eth挖矿虚拟内存设置 挖eth至少需要4g虚拟内存

㈠ ETH挖矿提示VRAM不足

换内核软件。
4G显存挖ETH出现DAG显存不足报错的,换成15.0内核软件都可以解决问题,此故障过段时间会大面积报错。
更新一下显卡驱动或者虚拟内存弄大一点,把ETH删掉试试,我的就是这个问题,打上ETH补丁魅力吗跳出你这个提示,只能设置成窗口模式玩,把ETH删除掉就可以了。

㈡ 挖矿为什么要设置高虚拟内存

如果不设置高的虚拟内存,挖矿会占用系统大量内存导致卡顿崩溃。因为当挖矿开始时,将会大量占用分页内存,如果设置的虚拟内存不足,将会导致内存溢出的状况,直接导致的结果就是系统蓝屏。

还有的就是如虚拟内存不够,会导致挖矿显卡算力不正常或部分显卡算力不正常。这也同时强调了为什么要使用SSD作为系统盘的原因。SSD的零碎文件读写速率以及读写延时都远优于机械硬盘,相较而言更接近内存速率。

挖矿设备和环境:挖矿对电脑的硬件设备也是有所要求的,除了能正常开机使用,挖矿硬性要求是显卡:AMD和英伟达两家的显卡都可以,但是要求显存必须大于4G,无论是笔记本还是主机,只要显存大于4G,都可以用来挖矿。虚拟内存:单张GPU设置6G虚拟内存(如6张GPU则设置36G)。

在安装操作系统之后(约20GB),对于一个60GB的SSD来说依然有40GB的可用空间,可大胆的将其中16GB甚至32GB划分为虚拟内存,以保证挖矿过程中的系统稳定性。

虚拟内存:

设置虚拟内存,虚拟内存的概念是相对于物理内存而言的,当系统的物理内存空间入不敷出时,操作系统便会在硬盘上开辟一块磁盘空间当做内存使用,这部分硬盘空间就叫虚拟内存。

如何设置虚拟内存:

(一)合理设置虚拟内存

虚拟内存的设定主要根据你的物理内存大小和计算机的用途来设定,在桌面上用鼠标右击“本人的计算机”,选择“属性”,就可以看到内存了。根据微软公司的建议,虚拟内存设为物理内存容量的1.5--3倍,例如512MB的内存,虚拟内存设定为768--1536MB;1G的内存,虚拟内存设定为1536--3072MB。也可让Windows来主动分配管理虚拟内存,它可以根据实际内存的应用情况,动态调整虚拟内存的大小。在虚拟内存设置页面下方有一个推荐数值,假如确实不晓得设置几为最佳,建议虚拟内存就设为推荐的数值。虚拟内存有初始大小与最大值两个数值,最佳把初始大小和最大值设为相同,以避免系统频繁改变页面文件的大小,影响计算机运行。内存容量2GB或以上的,假如不运行大型文件或游戏,也可以关闭虚拟内存。

虚拟内存就是在你的物理内存不够用时把一部分硬盘空间作为内存来应用,不过由于硬盘传输的速度要比棱存传输速度慢的多,所以应用虚拟内存比物理内存效率要慢。个人实际需要的值应该本人多次调整为好。 设的太大会产生大量的碎片,严重影响系统速度,设的太小就不够用,于是系统就会提示你虚拟内存太小。

(二)虚拟内存设置办法

右击“本人的计算机”选择“属性--高级--性可以--设置--高级--虚拟内存--更加改”,选择虚拟内存所在的磁盘,然后在下边单击“自定义大小” 并写液闭入“初始大小”和“最大值”,最后按“设置”按钮,再确定即可。虚拟内存从C盘设置到其它磁盘的办法:右击本人的计算机--属性--高级--性可以设置--高级--虚拟内存更加改--点选C盘--单选“无分页文件”--“设置”,此时C盘旁的虚拟内存就消失了;然后选中D或F盘,单选“自定义大小”--在下面的“初始大小”和“最大值”两个文本框中写入数值--“设置”—确定--重启计算机,便完成了设置。

虚拟内存最佳不要与系统设在同一个磁盘内,内存是随着应用而动态地变化,设在C盘就容易产生磁盘碎片,影响系统运行速度。所以,最佳将虚拟内存设置在磁盘剩余空间较大而又不常用的磁盘,如D、F,这样可以避免系统在C盘进行频繁的读写操作而影响系统速度。虚拟内存在一台计算机,只用设置一次,可设置在任何一个磁盘。

(三)减轻内存负担:

1、打开的程序不可太多。假如同时打开的文档过多或者运行的程序过多,就没有足够的内存运行其他程序,要关闭不用的程序和窗口。

2、主动运行的程序不可太多 。单击“开始”--“运行”,键入“Msconfig”-“确定”,打开“系统配置实用程序”窗口闹盯裂,删除不想主动加载的启动项目。

BIOS里的虚拟内存怎么设?
BIOS是英文Basic Input/output System的缩写,意思是“基本输入/输出系统”。它是操作系统和硬件之间连接的桥梁,负责在电脑开启时检测、初始化系统设备、装入操作系统并调度操作系统向硬件发出的指令。

谈到BIOS,不能不先说说Firmeare(固件)和ROM(Read Only Memory,只读存储器)芯片。Firmeare是软件,但与普通的软件完全不同,它是固化在集成电路内部的程序代码,集成电路的功能就是由这些程序决定的。ROM是一种可在一次性写入Firmware(这就是“固化”过程)后,多次读取的集成电路块。由此可见,ROM仅仅只是Firmware的载体,而我们通常所说的BIOS正是固化了系统主板Firmware的ROM芯片。

最初的主板BIOS芯片采用的是ROM,它的Firmware代码是在芯片生产过程中固化的,并且永远无法修改。后来,电脑中又采用了一种可重复写入的ROM作为系统BIOS芯片,这就是EPROM(Erasable Programmable ROM,可擦除可编程ROM)。

现在的主板BIOS几乎都采用Flash ROM(快闪ROM),它其实就是一种可快速读写的EEPROM(Electrically Erasable Programmable ROM),顾名思义,它是一种在一定的电压、电流条件下,可对其Firmware进行更新的集成电路块。兼容机和国产品牌机BIOS大多采用AWARD或AMI公司的Firmware,国外的品牌电脑的BIOS则几乎全部采用Phoenix公司的Firmware。不管BIOS软件代码有何区别,它们的硬件部分(Flash ROM芯片)是大致相同的,BIOS芯片大多位于主板的ISA和PCI插槽交汇处的上方(也有部分主板将BIOS芯片安排在主板的左下方位置),芯片表面一般贴有BIOS Firmware提供商的激光防伪标贴。一般不是直接焊在主板上,而是插在一个专用的插槽上。

有很多芯片厂商都在生产Flash ROM芯片,我们在主板上常见的有Winbond、SST、Intel、MXIC、ATMEL等品牌的产品,这些厂商又提供了很多种型号的芯片,型号不同,芯片的存储容量和读写电压也不同。Flash ROM芯片大致分为28、29两大系列28系列的Flash ROM芯片是双电压设计的,它可以在5V的电压的条件下读取,而写入则必须提供12V的电压。采用这种芯片的主板在升级时,会给普通的电脑用户造成不小的麻烦---要开机箱、改跳线设置,太麻烦了。29系列的Flash ROM芯片则相对简单,由于其采用单电压设计,读写都采用5V电压,因此只动用软件就可以完成读写Firmware的操作。在主板说明书中,主板厂商还列出了Flash ROM芯片的容量,其中有1M和2M两种容量的型号。这里,“M”的单位是指“Mbit”,1M的Flash ROM芯片实际能存储的容量为1Mbit=8*128Kbyte(1Byte=8bit),2M的芯片为256K。以上这些技术参数都可以通过芯片正面的编号来区分,这个编号是严格遵循集成电路编号规则来标注的,如:台湾Winbond(华邦)公司的Flash ROM芯片,芯片编号为“29C020”。前两位“29”表明这是一块5V电压读写的Flash ROM芯片,后面的“020”代表容量为2Mbit。如Intel生产的Flash ROM芯片,它的芯片编号为“28F010”,由此可知该芯片是5V读、12V写,容量为1Mbit的Flash ROM芯片。

如何设置虚拟内存
我的电脑--右键--属性--高级---性能点设置--高级--最下面的虚拟内存

虚拟内存即拿出一部分硬盘空间来充当内存使用,当内存占用完时,电脑就会自动调用硬盘来充当内存,以缓解内存的紧张。

虚拟内存放在剩余空间大点的盘就好(不建议放在系统盘)

物理内存是256的话,虚拟内存设置2-3倍

物理内存是512的话,虚拟内存设置1.5-2.5倍

物理内存是1G的话,虚拟内存设置1-2倍

如果经常运行大型程序,可以再设置高点

把不必要的进程关掉

有条件的话,最好还是加根内存条,呵呵

系统提示“内存不足”的九大原因及解决方法

一、剪贴板占用了太多的内存

二、打开的程序太多

如果同时打开的文档过多或者运行的程序过多,就没有足够的内存运行其他程序。这时,对于多文档界面(MDl)程序,如Word、Excel等,请关闭当前文档外的所有文档,并退出当前未使用的程序,然后或许你就能够继续执行因“内存不足”而被中断的任务。

三、重新启动计算机

如果只退出程序,并不重新启动计算机,程序可能无法将内存资源归还给系统。请重新启动计算机以释放系统资源,然后再次运行程序或执行被中断的任务。

四、自动运行的程序太多

如果在启动Windows时自动运行的程序太多,那么,即使重新启动计算机,也没足够的内存用来运行其它程序。

五、管理虚拟内存设置

如果没有设置让Windows管理虚拟内存或者禁用虚拟内存,那么计算机可能无法正常工作,也可能收到“内存不足”的消息,或在运行某程序时出现相同的错误消息。

六、增加可用磁盘空间

由于Windows以虚拟内存分页文件的格式使用硬盘空间以模拟RAM(),所以,尽管已设置为让Windows管理虚拟内存,但是当虚拟内存分页文件所在的驱动器(默认为Windows系统所在的硬盘分区)没有足够的空间时,仍会出现“内存不足”的错误。此时,请执行以下一项或多项操作,增加Windows虚拟内存分页文件所在驱动器上的可用空间:

七、程序文件被毁坏

如果仅仅是使用某个程序时,系统提示内存不足,而其他程序可以正常运行,那么可能的原因是该程序文件被毁坏,从而导致内存问题。然而Windows并没有确切地提示表明该程序已损坏,所以请尝试删除并重新安装该程序,然后重新运行该程序。如果系统不再提示内存不足,那么说明原程序文件确实被损坏。

八、使用内存优化软件

内存优化软件有很多,比如RAM Idle和Memo Kit就是比较出色的两个。这些软件都可以设置自动清空剪贴板、释放被关闭程序未释放的内存、对Win386.swp文件进行重新组织等,从而免除你手工操作的麻烦,达到自动释放内存的目的,不妨一试!

九、查杀病毒

系统感染电脑病毒也是导致内存不足的罪魁祸首,当系统出现“内存不足”的错误时,请使用最新的防毒软件查杀病毒,或者在清除电脑病毒之后,就解决了“内存不足”的问题。
虚拟内存怎么设置最好
建议虚拟内存初始大小与最大值都设置为1536MB,设置相同数值是为了避免产生碎片,最好不要设置在C盘,设置在有足够空间的盘。

怎样设置虚拟内存:

(一)合理设置虚拟内存

虚拟内存的设定主要根据你的物理内存大小和电脑的用途来设定,在桌面上用鼠标右击“我的电脑”,选择“属性”,就可以看到内存了。根据微软公司的建议,虚拟内存设为物理内存容量的1.5--3倍,例如512MB的内存,虚拟内存设定为768--1536MB;1G的内存,虚拟内存设定为1536--3072MB。也可让Windows来自动分配管理虚拟内存,它能根据实际内存的使用情况,动态调整虚拟内存的大小。在虚拟内存设置页面下方有一个推荐数值,如果确实不知道设置多少为最佳,建议虚拟内存就设为推荐的数值。虚拟内存有初始大小与最大值两个数值,最好把初始大小和最大值设为相同,以避免系统频繁改变页面文件的大小,影响电脑运行。内存容量2GB或以上的,如果不运行大型文件或游戏,也可以关闭虚拟内存。

虚拟内存就是在你的物理内存不够用时把一部分硬盘空间作为内存来使用,不过由于硬盘传输的速度要比内存传输速度慢的多,所以使用虚拟内存比物理内存效率要慢。个人实际需要的值应该自己多次调整为好。 设的太大会产生大量的碎片,严重影响系统速度,设的太小就不够用,于是系统就会提示你虚拟内存太小。

(二)虚拟内存设置方法

右击“我的电脑”选择“属性--高级--性能--设置--高级--虚拟内存--更改”,选择虚拟内存所在的磁盘,然后在下边单击“自定义大小” 并输入“初始大小”和“最大值”,最后按“设置”按钮,再确定即可。虚拟内存从C盘设置到其它磁盘的方法(如果在其它盘,设置方法一样):右击我的电脑--属性--高级--性能设置--高级--虚拟内存更改--点选C盘--单选“无分页文件”--“设置”,此时C盘旁的虚拟内存就消失了;然后选中D或F盘,单选“自定义大小”--在下面的“初始大小”和“最大值”两个文本框中输入数值--“设置”—确定--重启电脑,便完成了设置。

虚拟内存最好不要与系统设在同一个磁盘内,内存是随着使用而动态地变化,设在C盘就容易产生磁盘碎片,影响系统运行速度。所以,最好将虚拟内存设置在磁盘剩余空间较大而又不常用的磁盘,如D、F,这样可以避免系统在C盘进行频繁的读写操作而影响系统速度。虚拟内存在一台电脑,只用设置一次,可设置在任何一个磁盘。

(三)减轻内存负担:

1、打开的程序不可太多。如果同时打开的文档过多或者运行的程序过多,就没有足够的内存运行其他程序,要关闭不用的程序和窗口。

2、自动运行的程序不可太多 。单击“开始”--“运行”,键入“Msconfig”-“确定”,打开“系统配置实用程序”窗口,删除不想自动加载的启动项目
win7系统怎么调整虚拟内存
首先,对着“计算机”图标击右键,选择“属性”。

在打开的界面中,选择“高级系统设置”。

在打开的系统属性设置中,点击“设置”,即可打开虚拟内存的有关设置。

在高级系统设置中,点击“性能选项”中的“虚拟内存”的设置,点击“更改”。

系统设置界面中提供给了推荐的虚拟内存值,因为对于每一个驱动器都需要有一个虚拟内存的设置,对于每一个页面文件的设置,下面是常见的设置方案。一般情况下,只需要对C盘驱动器进行虚拟内存大小的设置,如果物理内存为2GB,推荐虚拟内存的最大值设置为1.5~2倍左右即可。因此,点击自定义设置,然后输入相关的数值即可。

最后点击“确定”,然后计算机重新启动即可。

㈦ windows7 500g的更盘 3G的内存玩大型单机游戏 虚拟内存该怎么设置

你内存基本上够用了(不玩大型3d情况下)如果对虚拟内存该怎么设置不够了解情况下请看下详细介绍:
当系统运行时,先要将所需的指令和数据从外部存储器(如硬盘、软盘、光盘等)调入内存中,CPU再从内存中读取指令或数据进行运算,并将运算结果存入内存中,内存所起的作散没橡用就像一个“二传手”的作用。当运行一个程序需要大量数据、占用大量内存时,内存这个仓库就会被“塞满”,而在这个“仓库”中总有一部分暂时不用的数据占据着有限的空间,所以要将这部分“惰性”的数据“请”出去,以腾出地方给“活性”数据使用。这时就需要新建另一个后备“仓库”去存放“惰性”数据。由于硬盘的空间很大,所以微软Windows 操作系统就将后备“仓库”的地址选在硬盘上,这个后备“仓库”就是虚拟内存。在默认情况下,虚拟内存是以名为Pagefile.sys的交换文件保存在硬盘的系统分区中。

手动设置虚拟内存

在默认状态下,是让系统管理虚拟内存的,但是系统默认设置的管理方式通常比较保守,在自动调节时会造成页面文件不连续,而降低读写效率,工作效率就显得不高,于是经常会出现“内存不足”这样的提示,下面就自已动手来设置它吧。

①用右键点击桌面上的“我的电脑”图标,在出现的右键菜单中选择“属性”选项打开“系统属性”窗口。在窗口中点击“高级”选项卡,出现高级设置的对话框。

②点击“性能”区域的“设置”按钮,在出现的“性能选项”窗口中选择“高级”选项卡,打开其对话框。

③在该对话框中可看到关于虚拟内存的区域,点击“更改”按钮进入“虚拟内存”的设置窗口。选择一个有较大空闲容量的分区,勾选“自定义大小”前的复选框,将具体数值填入“初始大小”、“最大值”栏中,而后依次点击“设置→确定”按钮即可,最后重新启动计算机使虚拟内存设置生效。

建议:可以划分出一个小分区专门提供给虚拟内存、IE临时文件存储等使用,以后可以对该分区定期进行磁盘整理,从而能更好提高计算机的工作效率。

一、量身定制虚似内存

1.普通设置法

根据一般的设置方法,虚察尘拟内存交换文件最小值、最大值同时都可设为内存容量的1.5倍,但如果内存本身容量比较大,比如内存是512MB,那么它占用的空间也是很可观的。所以可以这样设定虚拟内存的基本数值:内存容量在256MB以下,就设置为1.5倍;在512MB以冲旁上,设置为内存容量的一半;介于256MB与512MB之间的设为与内存容量相同值。

2.精准设置法

由于每个人实际操作的应用程序不可能一样,比如有些人要运行3DMAX、Photoshop等这样的大型程序,而有些人可能只是打打字、玩些小游戏,所以对虚拟内存的要求并不相同,于是就要因地制宜地精确设置虚拟内存空间的数值。

①先将虚拟内存自定义的“初始大小”、“最大值”设为两个相同的数值,比如500MB;

②然后依次打开“控制面板→管理工具→性能”,在出现的“性能”对话框中,展开左侧栏目中的“性能日志和警报”,选中其下的“计数器日志”,在右侧栏目中空白处点击右键,选择右键菜单中的“新建日志设置”选项;

③在弹出的对话框“名称”一栏中填入任意名称,比如“虚拟内存测试”。在出现窗口中点击“添加计数器”按钮进入下一个窗口;

④在该窗口中打开“性能对象”的下拉列表,选择其中的“Paging File”,勾选“从列表中选择计数器”,并在下方的栏目中选择“%Usage Peak”;勾选“从列表中选择范例”,在下方的栏目中选择“_Total”,再依次点击“添加→关闭”结束;

⑥在右侧栏目中可以发现多了一个“虚拟内存测试”项目,如果该项目为红色则说明还没有启动,点击该项,选择右键菜单中的“启动”选项即可;

接下来运行自己常用的一些应用程序,运行一段时间后,进入日志文件所在的系统分区下默认目录“PerfLogs”,找到“虚拟内存测试_000001.csv”并用记事本程序打开它,在该内容中,查看每一栏中倒数第二项数值,这个数值是虚拟内存的使用比率,找到这项数值的最大值,比如图中的“46”,用46%乘以500MB(前面所设定的虚拟内存数值),得出数值为230MB。

用该数值可以将初始大小设为230MB,而最大值可以根据磁盘空间大小自由设定,一般建议将它设置为最小值的2到3倍。这样就可以将虚拟内存打造得更精准,使自己的爱机运行得更加流畅、更具效率

二、Windows虚拟内存加速密籍

虚拟内存对于任何版本的Windows而言都是十分重要的。如果设置得当,它将极大地提升电脑的性能和运行速度。可是在默认状态下,Windows始终将虚拟内存设为物理内存的1.5倍。这样的话,如果用户安装2GB的内存,系统就会腾出高达3GB的硬盘空间作为虚拟内存。但以当前的主流应用软件和游戏对内存的需要来看,根本没有必要使用这么多的虚拟内存。那么,有没有什么秘技或绝招可使虚拟内存运用得更有效率或更显性能呢?

1、分割存于多个硬盘

将虚拟内存设在较快的硬盘上,的确可使虚拟内存的运作更有效率。但是若电脑上两个硬盘速度一样快,则应将虚拟内存平均分配在两个不同的硬盘上(并非同一硬盘的不同分区)。因为同步进行读写操作会更有效地提高系统整体的虚拟内存性能。

举个例子,假设你原本在硬盘C上设置了700MB的虚拟内存,现在你可尝试重新分配,即把硬盘C改为350MB,硬盘D新增350MB的虚拟内存。理论上这样做会加快虚拟内存整体的读写操作.

2、硬盘需有足够空间

如果你不是很有经验的电脑用户,又或者没有特殊的使用要求,在Windows XP中选择“系统管理的大小”的方法来自动处理虚拟内存,一般情况下应该会比选择“自定义大小”的方法来得安全和稳定。不过,有一点大家必须注意,由于虚拟内存的“页面文件”(pagefile.sys)会随着电脑使用过程进行收缩和扩展,为使系统管理虚拟内存能够进行得顺利和更具弹性,必须保证分页文件所在的硬盘拥有足够的可用空间。

3、最小值等于最大值

选择“自定义大小”的方法来处理虚拟内存,并将最大值和最小值都设为同一数值。有很多人都相信用这种方法来处理虚拟内存有助于提高系统的性能。他们所持的理由是,当最大值和最小值都相等时,系统无需时刻进行收缩和扩展页面文件的动作。省去了这些工作,相应地就是提高系统效率。

这种方法,很多人坚信有效,但同样地,也有人指出其实并没有效果。但不管怎样也好,如要将最大值和最小值设为相等,必须坚守一个原则,那就是虚拟内存的大小必须足够,否则系统轻则会出现效率下降(要进行更多复写动作来腾出空间),严重的更会造成系统不稳定。

4、整理页面文件

文件数据保存在硬盘上久了,文件碎片(fragment)自然会产生。要保持或提高硬盘的工作效率,应不时为硬盘进行一次碎片整理。所谓虚拟内存,其实也是硬盘上的资料文件,那么虚拟内存是否也应该像普通文件般需要整理呢?

Windows系统处理页面文件(即虚拟内存)的方法有别于一般的文件。相比之下,页面文件比一般文件更少出现碎片,为页面文件进行整理通常是没有必要的。事实上,当Windows XP进行磁盘碎片整理时,页面文件不会牵涉其中。

虽然Windows不会对页面文件进行整理,但事实上页面文件也有碎片存在。追求“尽善尽美”的朋友可能仍想对页面文件进行碎片整理。大家不妨试试下面的方法:

在桌面“我的电脑”图标上单击鼠标右键,在随后出现的功能菜单中选“属性”。进入系统属性的设置窗口,用鼠标点选“高级”-->“性能”-->“设置”-->“高级”-->“更改”,在随后出现的“虚拟内存”设置窗口中选中“无分页文件”一项。最后单击“设置”按钮退出,并重新启动电脑。

重新启动后,检查一下磁盘根目录中还有没有pagefile.sys页面文件存在,如有就将之删除。清除掉虚拟内存的页面文件后,现在再进行磁盘碎片整理。完成后,按照前面的步骤重新设置一定数量的虚拟内存,并启动电脑使之生效。经上述方法处理后,新得出的页面文件将会是没有碎片的。

另外,如果想查看页面文件碎片的具体情况呢?启动磁盘碎片整理程序,为存在有页面文件的硬盘进行一次“分析”,再点选“查看报告”,看看“页面文件碎片”一栏便会一目了然.

5、虚拟内存的理想大小

想以“自定义大小”的方法来处理虚拟内存,究竟应该设置多大的虚拟内存呢?在Windows XP中,如果由操作系统自己定义虚拟内存,系统通常会把最小值设置为物理内存的1.5倍。当扩展时,最大值则介于物理内存的2.5至3倍。一般情况下,用户想自定义虚拟内存的大小,均可参照这个比例设置。

真的要参照这个比例吗?如果电脑有1GB的内存,难不成最小值要设置为1.5GB,最大值是2.5至3GB。这样一来。Pagefile.sys页面文件至少为1.5GB,太不现实了!

其实,大内存的系统跟小内存的系统相比,在设置虚拟内存时,标准有些不同。

如果大家有512MB以上甚至1GB的内存,既然物理内存已经相当充足,所需的虚拟内存反而应该减少。故在大内存的系统中,虚拟内存的最小值可以设成物理内存的一半。比如有1GB的内存,虚拟内存的最小值设成512MB,最大值则维持3GB以备不时之需。注意:虽然最大值设为3GB,系统是不会立即出现3GB大小的pagefile.sys文件,实际上它首先会以最小值出现,待有扩展需要时才会递增。

另外,有些大内存的朋友,可能会干脆不设置虚拟内存,以此强迫系统使用速度较快的内存。其实这是不太明智的做法。正所谓凡事都不要做得太绝对,完全没有虚拟内存也不行。原因是不少应用程序在设计时要求必须使用虚拟内存,没有了就会造成系统不稳定或死机。

至于小内存的系统,例如256MB,参照1.5倍及3倍的设置比例最稳当。即虚拟内存最小值设为384MB,最大值768MB。

6、手工订制最准确的虚拟内存

0.5倍、1.5倍、3倍,哇!好像买衣服时分大、中、小号,完全没有个性。究竟设置虚拟内存有没有更“贴身剪裁”的方法呢?

在Windows XP桌面的“开始”→“运行”中输入perfmon.msc,一个与系统性能有关的监视器便会出现。看看显示器的底部,有三个计数器(pages/sec、Avg.Disk Queue Length及rocessor Time,)。为了便于接下来对虚拟内存的页面文件进行精确监测,现在请大家将这三个计数器逐一点选,并按键盘上的Delete键将它们删除。请大家放心,删除后,下次再启动系统性能监视器时,这三个项目会重新出现。

删除后,现在请在图表中央位置单击鼠标右键,在随后出现的功能菜单中点选“添加计数器”一项,跟着在跳出窗口的“性能对象”一栏选“Process”。之后再在“从列表选择”一栏中点选“Page File Bytes”。不清楚“Page File Bytes”代表什么意思,只要单击“说明”按钮,解说文字便会出现在对话框之下。

选定“Page File Bytes”后,再在右方的“从列表选择范例”一栏选取“Total”项,之后依次单击“添加”和“关闭”按钮,一个名为“Page File Bytes”的计数器便会出现在性能监视器的下方中。

重复以上的动作,再添加一个名为“Page File Bytes Peak”的计数器(即Process下面的Page File Bytes Peak)。

现在,回头看一下监视器,图表中应该正在显示并计量着刚才新增加的两个计数器。如无意外,这两个计数器在图表上的显示不正确,即数值靠近最高比例线,没有动态变化。不用怕,这并不表示你的电脑出了什么问题,而是图表比例设得不太恰当而已!用鼠标右键逐一单击监视器底部的“Page Fele Bytes”和“Page File By8tes Peak”计数器,并选“属性”一项。在“数据”页面的“比例”一栏中改为0.0000001,这样显示器中的图表便不再是没有动静了。

如果你看过系统提供的说明,相信应该知道“Page File Bytes”和“Page File Bytes Peak”正是代表了系统监测期间所使用的虚拟内存及其峰值是多大。因此,需要精确地手工设置虚拟内存,可参考图表下方显示的数字,其单位是Bytes。

想知道在正常的情况下,你的系统会耗用多少虚拟内存?请将平时日常使用的应用软件同时启动并让它们开始工作,接着再看性能监视器上所显示的数值,心中有数了吧。

人总有疯狂的时候,想知道自己疯狂使用电脑时系统需要多少虚拟内存,现在就尽情地将电脑上的程序启动并运行(例如,开十多个IE浏览器窗口上网,播放MP3和DVD影片,再进行光盘刻录或DV影片压缩编码),看看监视器的百分比会升高到多少。

在图表上右击鼠标,点选“属性”,进入“图表”页面勾选“水平格线”一项。这样图表中会出现一条条的水平分割线,是不是好分辨了?

图表中的红色垂直线跑得太快,来不及开启电脑上的程序进行测试?

同样,在图表上单击鼠标右键,选“属性”,在常规页面的“自动抽样间隔”一项中将1秒改为5秒。此时,图表中的“图形时间”数值便会由1分40秒变成8分20秒。换言之,红色垂直线走完一圈需花费8分20秒,这个时间应该足以让大家开启并运行很多应用程序,然后再慢慢查看图表中的结果。

最后,通过监视器的图表,相信大家已经能粗略估计你的电脑系统应设置多大的虚拟内存了。

三、出现“虚拟内存不够”的几个可能

1、感染病毒

有些病毒发作时会占用大量内存空间,导致系统出现内存不足的问题。赶快去杀毒,升级病毒库,然后把防毒措施做好!

2、虚拟内存设置不当

虚拟内存设置不当也可能导致出现内存不足问题,一般情况下,虚拟内存大小为物理内存大小的2倍即可,如果设置得过小,就会影响系统程序的正常运行。重新调整虚拟内存大小以WinXP为例,右键点击“我的电脑”,选择“属性”,然后在“高级”标签页,点击“性能”框中的“设置”按钮,切换到“高级”标签页,然后在“虚拟内存”框中点击“更改”按钮,接着重新设置虚拟内存大小,完成后重新启动系统就好了。

3、系统空间不足

虚拟内存文件默认是在系统盘中,如WinXP的虚拟内存文件名为“pagefile.sys”,如果系统盘剩余空间过小,导致虚拟内存不足,也会出现内存不足的问题。系统盘至少要保留300MB剩余空间,当然这个数值要根据用户的实际需要而定。用户尽量不要把各种应用软件安装在系统盘中,保证有足够的空间供虚拟内存文件使用,而且最好把虚拟内存文件安放到非系统盘中。

4、因为SYSTEM用户权限设置不当

基于NT内核的Windows系统启动时,SYSTEM用户会为系统创建虚拟内存文件。有些用户为了系统的安全,采用NTFS文件系统,但却取消了SYSTEM用户在系统盘“写入”和“修改”的权限,这样就无法为系统创建虚拟内存文件,运行大型程序时,也会出现内存不足的问题。问题很好解决,只要重新赋予SYSTEM用户“写入”和“修改”的权限即可,不过这个仅限于使用NTFS文件系统的用户。

四、虚拟内存的优化

1. 启用磁盘写入缓存

在“我的电脑”上单击鼠标右键选择“属性->硬件”,打开设备管理器找到当前正在使用的硬盘,单击鼠标右键选择属性。在硬盘属性的的“策略”页中,打开“启用磁盘上的写入缓存”。

这个选项将会激活硬盘的写入缓存,从而提高硬盘的读写速度。不过要注意一点,这个功能打开后,如果计算机突然断电可能会导致无法挽回的数据丢失。因此最好在有UPS的情况下再打开这个功能。当然,如果你平常使用计算机时不要进行什么重要的数据处理工作,没有UPS也无所谓,这个功能不会对系统造成太大的损失。

2. 打开Ultra MDA

在设备管理其中选择IDE ATA/ATAPI控制器中的“基本/次要IDE控制器”,单击鼠标右键选择“属性”,打开“高级设置”页。这里最重要的设置项目就是“传输模式”,一般应当选择“DMA(若可用)”。

3. 配置恢复选项

Windows XP 运行过程中碰到致命错误时会将内存的快照保存为一个文件,以便进行系统调试时使用,对于大多数普通用户而言,这个文件是没有什么用处的,反而会影响虚拟内存的性能。所以应当将其关闭。

在“我的电脑”上单击鼠标右键,选择“属性->高级”,在“性能”下面单击“设置”按钮,在“性能选项”中选择“高级”页。这里有一个“内存使用”选项,如果将其设置为“系统缓存”,Windows XP 将使用约4MB的物理内存作为读写硬盘的缓存,这样就可以大大提高物理内存和虚拟内存之间的数据交换速度。默认情况下,这个选项是关闭的,如果计算机的物理内存比较充足,比如256M或者更多,最好打开这个选项。但是如果物理内存比较紧张,还是应当保留默认的选项。

页面文件的设置

一、页面文件的大小计算

对于不同的计算机而言,页面文件的大小是各不相同的。关于页面文件大小的设置,有两个流传甚广的“公式”,“物理内存X2.5”或者“物理内存X1.5”。这两种计算方法固然简便,但是并不适用于所有的计算机。设置页面文件大小最准确的方法是看看计算机在平常运行中实际使用的页面文件大小。

通过Windows XP自带的日志功能可以监视计算机平常使用的页面文件的大小,从而进行最准确的设置,具体步骤如下。

1、在“我的电脑”上单击鼠标右键,选择“属性->高级”,单击“性能”下面的“设置”按钮,然后选择“高级”页,单击“虚拟内存”下方的“更改”按钮。选择“自定义大小”,并将“起始大小”和“最大值”都设置为300M,这只是一个临时性的设置。设置完成后重新启动计算机使设置生效。

2、进入“控制面板->性能与维护->管理工具”“性能”“性能日志和警告”“计数器日志”。在窗口右侧单击鼠标右键选择“新建日志设置”

3、随便设置一个日志名称,比如“监视虚拟内存大小”。

4、在“常规”页中单击“添加计数器”按钮。

在“性能对象”中选择“Paging File”,然后选中“从列表选择记数器”下面的“%Usage Peak”,并在右侧“从列表中选择范例”中选择“_Total”。最后单击“添加”和“关闭”按钮。

5、别忘了记住“日志文件”页中的日志文件存放位置和文件名,后面需要查看这个日志来判断Windows XP平常到底用了多少虚拟内存,在这个例子中,日志文件被存放在D:\Perflog目录下。

另外还要设置“日志文件类型”为“文本文件”,这样便于阅读。

这时你可以看到刚才新建的日志条目前面的图标变成了绿色,这表明日志系统已经在监视虚拟内存了。如果图标还是红色,你应该单击鼠标右键选择“开始”来启动这个日志。

过一段时间后打开这个CVS文件,可以看到如下内容的条目。

这个日志文件记录这一段时间中页面文件的使用情况,注意这里的单位是%,而不是MB。通过简单的计算,就可以得到页面文件的最小尺寸,公式是“页面文件尺寸X百分比”。比如这个例子中,虚拟内存最大的使用比率是31%,300MBX31%=93MB,这个值就是虚拟内存的最小值(注意,300MB是前面的设置的临时值)。

如果物理内存较大,可以考虑将页面文件的“起始大小”和“最大值”设置为相等,等于上一步中计算出来的大小。这样硬盘中不会因为页面文件过渡膨胀产生磁盘碎片,其副作用是由于“最大值”被设置的较小,万一偶然出现虚拟内存超支的情况,可能会导致系统崩溃。

设置页面文件

现在回到“虚拟内存”的设置对话框中选择自定义大小并按照上面的计算结果分别设置“初始大小”和“最大值”。这里将“初始大小”设置为91M,而将“最大值”设置成了200M,这样比较保险。

对页面文件进行碎片整理

Windows XP运行时需要大量访问页面文件,如果页面文件出现碎片,系统性能将会受到严重影响,而且会缩短硬盘的使用寿命。所以很有必要对页面文件定期进行碎片整理。

不过别忘了,页面文件是系统关键文件,Windows XP运行时无法对其进行访问。所以对它进行碎片整理并不是一件容易的事情。有两种方案可以选择,一是安装Windows双系统,然后启动另外一个Windows对Windows XP所在的分区进行碎片整理。二是使用专门的工具软件,比如System File Defragmenter等。

㈧ 怎么改电脑的虚拟内存

步骤

1,右键单击“此电脑”, 选择最下方的“属性”

2,点击左边的“高级系统设置”点击打开

8,嫌指闷还需要进行重启让虚拟内存生效点击确定重启即可

㈨ 电脑怎么修改虚拟内存

问题一:电脑CPU如何修改虚拟内存 右键“我的电脑”――属性――高级”贺枣――点“性能”下面的“设置”――点“高
级”――点“虚拟内存”下方的“更改”――点“自定义大小”――根据你的实际情况
设置最大值和最小值(我内存256,设的最小值512M,最大值1024M)――也可以把它们
都设成实际内存的2――3倍(假使实际内存=或小于256M)――点设置――3次确定――重启。

问题二:怎样修改电脑虚拟内存 大小 ? 右击“我的电脑”,左键点“属性”---“高级”--“性能(设置)”---“高级”----“虚拟内存(更改)”---“自定义大小(设置)”根据你物理内存的大小设置为物理内存数值的1.5或2倍大小就行了。一般利用系统的默认大小就可以,要是系统经常提示你虚拟内存小,那你可以把数值设大一点,也不要太大哦,还要看你系统盘的剩余容量啊。当然,你也可以把分页文件“虚拟内存”转移到其他分区,点你要设置的分区,假如你想把分页文件转移到“d”盘,就点“d”,设置好虚拟内存的数值后点“确定”就行矗(需要重新启动)。

问题三:我电脑内存4G,虚拟内存如何设置 一般来说4G不需要虚拟内存,但是。。。。。
一般来悄拍升说虚拟内存是实际内存的1.5~2倍,所以4G设1.5~2倍太大了,所以你先设2G,如果还是吃紧,就设为4G。
一般来说虚拟内存都不设在C盘下

问题四:怎么修改电脑虚拟内存大小,多少合适 修改电脑虚拟内存方法
1、右击“计算机”,选择“属性”。
2、在打开的“系统”界面中,单击左侧的“高级系统设置”。
3、在打开的“系统属性”界面中,切换到“高级”标签,单击性能选项框里面的“设置”按钮。
4、在打开的“性能选项”的窗口中,选择“高级”标签,然后选择“更改”。
5、去掉“自动管理所有驱动器的分页文件大小”的“√”,选择一个盘符,不建议放到系统盘,可以找一个空间比较大的盘符,自定义大小即可,如果不知道设置为多少,可以设置成
6、设置完成以后,重启计算机即可。
虚拟内存通常设置为物理内存的1.5倍或2倍,推荐固定大小。过大的页面文件不仅占用磁盘空间,而且对性能没有什么帮助,因为硬盘的读写速度十分有限。物理内存3GB,虚拟内存设置为1G就可以罚,日常的应用占用内存不会超过3GB,设置太大没有什么意义

问题五:电脑的虚拟内存设置在哪里?怎么打开 20分 【简易步骤】:
【我的电脑】右键―【属性】―【高级】―【性能】―【设置】―【高级】―【虚拟内存】

1.在【我的电脑】上单击右键,点击【属性】―【启老高级】―【性能】―【设置】。(如图1)
图1
2.然后点击【高级】―【虚拟内存】―【更改】。
3.需要把虚拟内存更改到哪个分区就直接点击对应的分区,再选择【自定义大小】进行调节。
一般虚拟内存设置为物理内存的【1.5―3倍】即可。
注:如何查看物理内存大小。
右键点击【我的电脑】―【属性】―【常规】选项卡,下图中粉线上边的就是物理内存信息。

问题六:如何设置电脑虚拟内存最好 建议将初始大小和最大值同时设置为你物理内存的1-2倍,比如1G设置为2048MB(1G内存是2倍),2G设置为4096MB(2G内存是2倍),3G设置为4608MB(3G内存是1.5倍),4G内存先设置为4096MB(4G的1倍不够在加),如果你的物理内存小于2G或是2G,建议升级一下你的物理内存(初始大小和最大值设置要一致)。
设置虚拟内存方法:右击我的电脑/属性/高级/性能中的设置/高级/虚拟内存中的更改/选自定义大小,在初始大小和最大值,同时设为你的物理内存的1-2倍。如果你的内存是1G,就将初始大小和最大值同时设置为2048MB。设置后需按“设置”按钮,然后再按确定和应用,重新启动电脑设置生效。
右键计算机/属性/高级系统的设置/高级/性能/设置/高级/虚拟内存更改/进入调节界面(就和上面说的差不多了Win7系统)
你没有说你的内存是多大的,参考上面设置即可。

问题七:win7 4g内存 虚拟内存怎么设置最好 根本不用这么大,虚拟内存是做为物理内存的补充,速度有限,设置太大没多大作用,一般设置在C盘就行,其他盘不用设置,你现在用的物理内存有4G,初始大小建议设置为1024,最大值建议设置为4096,如果这样都提示内存不足,你应该互虑加内存了。

问题八:计算机虚拟内存怎么设置 如果你的系统盘空间够的话,可以不用考虑虚拟内存以及它存放的位置的。因为你的物理郸存已经够大,虚拟内存的使用率是很低的。当然如果把虚拟内存放在非系统盘的位置,会稍微的加快系统的运行速度,也会稍微延长硬盘的寿命。要设置虚拟内存,在“我的电脑”点右键->属性->高级->性能->设置->
高级->虚拟内存->更改,你会发现系统有个默认值,默认值一般为物理内存的1.5倍到3倍。也就是最低1.5倍,最高3倍。你就用默认的好了。然后点别的分区进行设置,比如你要把虚拟内存放在E盘,你就点E盘,然后设置最低值与最高值。然后把原来c盘的虚拟内存设置为空,即选择“无分页文件”。保存退出,系统要求重启。重启以后,虚拟内存就被放到了E盘。要查看的话,你可以显示所有隐藏文件(包括系统文件),到E盘看看是不是有个“pagefiles.sys”,这个就是虚拟内存的文件了。

问题九:电脑虚拟内存怎么设置 电脑虚拟内存的设置技巧 以win7系统为例,计算机右键,属性,高级系统设置,性能>设置,高级,虚拟内存>更改,自动管理取消,自定义大小,设置,确定,退出重启。


㈠ETH mining prompts insufficient VRAM

Replace the kernel software.
If an error occurs when mining ETH with 4G video memory and there is insufficient DAG memory, switching to 15.0 kernel software can solve the problem. This fault will cause a large number of errors after a period of time.
Update the graphics card driver or make the virtual memory larger. Try deleting ETH. This is my problem. Is it charming to apply ETH patch? You will get this prompt. You can only set it to window mode to play. Delete ETH. That's it.

㈡ Why should high virtual memory be set for mining?

If high virtual memory is not set, mining will occupy a large amount of system memory and cause lags and crashes. Because when mining starts, a large amount of paging memory will be occupied. If the virtual memory set is insufficient, it will cause a memory overflow situation, and the direct result will be a system blue screen.

In addition, if the virtual memory is not enough, it will cause the mining graphics card to have abnormal computing power or some graphics cards to have abnormal computing power. This also emphasizes the reason why SSD should be used as the system disk. SSD's system file read and write speed and read and write latency are much better than those of mechanical hard disks, and are closer to the memory speed in comparison.

Mining equipment and environment: Mining also requires computer hardware equipment. In addition to being able to be turned on normally, the hard requirement for mining is a graphics card: AMD and Nvidia. Any home graphics card is acceptable, but the video memory must be greater than 4G. Whether it is a laptop or a host, as long as the graphics memory is greater than 4G, it can be used for mining. Virtual memory: Set 6G virtual memory for a single GPU (for example, set 36G for 6 GPUs).

After installing the operating system (about 20GB), there is still 40GB of available space for a 60GB SSD. You can boldly divide 16GB or even 32GB of it into virtual memory to ensure that during the mining process system stability.

Virtual memory:

Set virtual memory. The concept of virtual memory is relative to physical memory. When the physical memory space of the system cannot make ends meet, the operating system will store it on the hard disk. Allocate a piece of disk space to use as memory. This part of the hard disk space is called virtual memory.

㈢ How to solve the error reported by the hd7990 graphics card 3G mining software

Mining generally requires a relatively high-end and powerful graphics card. Mining consumes the performance of the graphics card.

It is recommended to replace or check the graphics card driver version to see if it is the same. If it is still the same, reinstall the system. It is recommended to use the latest version of win10.

㈣ How to set up virtual memory

1. First open My Computer, find the "This Computer" icon on the system desktop, right-click the icon and click in the pop-up menu "Properties" option.

㈤ How to set virtual memory for 3G memory

It is recommended to set the initial size and maximum value to the same1-2 times the physical memory. If the physical memory is 3G, set it to 3072-4608MB (3G memory is 1-1.5 times, and the initial size and maximum setting must be consistent).

How to set virtual memory: Right-click My Computer/Properties/Advanced/Performance Settings/Advanced/Change in Virtual Memory/Select Custom Size, and check the initial size and maximum value. At the same time, set it to 1-2 times the physical memory. If your memory is 3G, set both the initial size and the maximum size to 3072-4608MB. After setting, you need to press the "Set" button, then press OK and Apply, and restart the computer for the settings to take effect.

First press the small setting. If it is not enough, the system will prompt you to change it to a larger one.

㈥ How to change virtual memory

How to set virtual memory best
Actual memory - 2 times actual memory. For example, if the memory is 2G, it is set to 2046-4092, and if the memory is 4G, it is 4092. -8184, do not set it on the system disk.
How to adjust virtual memory in ps
Right-click "My Computer", select "Properties", then on the "Advanced" tab, click the "Settings" button in the "Performance" box, switch to "Advanced" tab, then click the "Change" button in the "Virtual Memory" box, then reset the virtual memory size, and then restart the system.
How to set virtual memory for the hard disk
You can right-click the "My Computer" icon on the desktop, click "Properties", click the "Advanced" tab in the pop-up window, and click "Performance" Click the "Settings" button in the area, click the "Advanced" tab, and click the "Change" button in the "Virtual Memory" area. At this time, in the upper part of the window, select the partition where the virtual memory is to be stored. After selecting, click "Custom Size" at the bottom and enter the virtual memory size to be set in the "Initial Size" and "Maximum Value" boxes. (unit is megabytes), then click the "Settings" button, and finally click the "OK" button to close the window.

It is recommended to set the partition where the virtual memory is saved to a non-system partition, and the system default save partition is the system partition. In this case, you can first select C in the settings window with the partition list mentioned above. drive, then click "No paging file" below, click the "Settings" button, click other non-system partitions in the list, such as D drive, then click "Custom size", set the minimum and maximum values, and click The "Settings" button will do the trick. It is recommended that the maximum and minimum values ​​be set to the same size. This can effectively reduce the formation of disk fragments and cause a decrease in system performance and running speed. The default virtual memory size is generally 1.5 times the physical memory. Yours is 2G memory. The default virtual memory size is 3G. You can set the initial size and maximum value to 4096, which is 4G.

How to change virtual memory to the best one?
How to set up virtual memory:

(1) Properly set up virtual memory

The setting of virtual memory is mainly based on your You can set the physical memory size and the purpose of the computer. Right-click "My Computer" on the desktop and select "Properties" to see the memory. According to Microsoft's recommendations, the virtual memory is set to 1.5--3 times the physical memory capacity. For example, for 512MB of memory, the virtual memory is set to 768--1536MB; for 1G of memory, the virtual memory is set to 1536--3072MB. You can also let Windows actively allocate and manage virtual memory. It can dynamically adjust the size of virtual memory based on actual memory usage. There is a recommended value at the bottom of the virtual memory settings page. If you really don't know what the optimal setting is, it is recommended that the virtual memory be set to the recommended value. Virtual memory has two values: initial size and maximum value. It is best to set the initial size and maximum value to be the same to prevent the system from frequently changing the size of the page file and affecting the computer operation. If the memory capacity is 2GB or more, you can also turn off virtual memory if you are not running large files or games.

Virtual memory is to use part of the hard disk space as memory when your physical memory is not enough. However, since the transmission speed of the hard disk is much slower than the transmission speed of the memory, the use of virtual memory is better than that of physical memory. The efficiency is slower. The value that an individual actually needs should be adjusted several times by himself. If it is set too large, it will produce a lot of fragments, which will seriously affect the system speed. If it is set too small, it will not be enough, so the system will prompt you that the virtual memory is too small.

(2) Virtual memory setting method

Right-click "My Computer" and select "Properties--Advanced--Performance--Settings--Advanced--Virtual Memory" --Modify", select the disk where the virtual memory is located, then click "Custom size" below and enter "Initial size" and "Maximum value", and finally press the "Settings" button, and then confirm. How to set virtual memory from C drive to other disks: Right-click your computer--Properties--Advanced--Performance settings--Advanced--Virtual memory update--Click C drive--Select "No paging" File"--"Settings", then the virtual memory next to the C drive disappears; then select the D or F drive, single-click "Custom size"--"Initial size" and "Maximum value" below Write the value in the text box--"Settings"--OK--restart the computer to complete the setting.

It is best not to place the virtual memory on the same disk as the system. The memory changes dynamically with the application. If it is placed on the C drive, it will easily cause disk fragmentation and affect the system running speed. Therefore, it is best to set the virtual memory on disks with large remaining disk space that are not commonly used, such as D and F. This can avoid the system from performing frequent read and write operations on the C drive.operation and affect the system speed. Virtual memory only needs to be set once on a computer and can be set on any disk.

(3) Reduce memory burden:

1. Do not open too many programs. If there are too many documents open at the same time or too many programs running, there will not be enough memory to run other programs, so you need to close unused programs and windows.

2. There should not be too many actively running programs. Click "Start" - "Run", type "Msconfig" - "OK", open the "System Configuration Utility" window, and delete the startup items that you do not want to load automatically.

How to set up virtual memory in BIOS?
BIOS is the abbreviation of Basic Input/output System in English, which means "basic Input/Output System". It is the bridge between the operating system and the hardware. It is responsible for detecting and initializing system devices when the computer is turned on, loading the operating system and scheduling the instructions issued by the operating system to the hardware.

When talking about BIOS, we must first talk about Firmware (firmware) and ROM (Read Only Memory) chips. Firmeare is software, but it is completely different from ordinary software. It is the program code solidified inside the integrated circuit. The functions of the integrated circuit are determined by these programs. ROM is an integrated circuit block that can be read multiple times after being written to Firmware once (this is the "curing" process). It can be seen that ROM is just a carrier of Firmware, and what we usually call BIOS is the ROM chip that solidifies the Firmware of the system motherboard.

The original motherboard BIOS chip used ROM, and its Firmware code was solidified during the chip production process and can never be modified. Later, computers used a re-writable ROM as the system BIOS chip, which is EPROM (Erasable Programmable ROM).

Today's motherboard BIOS almost all uses Flash ROM (Flash ROM), which is actually a kind of EEPROM (Electrically Erasable Programmable ROM) that can be read and written quickly. As the name suggests, it is a kind of EEPROM that can be read and written quickly. An integrated circuit block whose Firmware can be updated under voltage and current conditions. Most of the BIOSes of compatible computers and domestic brand computers use AWARD or AMI Company's Firmware, while the BIOS of foreign brand computers almost all use Phoenix Company's Firmware.re. Regardless of the differences in BIOS software codes, their hardware parts (Flash ROM chips) are roughly the same. The BIOS chips are mostly located above the intersection of the motherboard's ISA and PCI slots (some motherboards also arrange the BIOS chip at the lower left of the motherboard). location), the surface of the chip is generally affixed with a laser anti-counterfeiting label from the BIOS Firmware provider. Generally, it is not soldered directly to the motherboard, but inserted into a dedicated slot.

There are many chip manufacturers producing Flash ROM chips. We commonly see Winbond, SST, Intel, MXIC, ATMEL and other brand products on motherboards. These manufacturers provide many types of chips. , different models have different storage capacity and read and write voltages of the chips. Flash ROM chips are roughly divided into two series: 28 and 29. The 28 series Flash ROM chips are designed with dual voltages. They can be read at a voltage of 5V, while writing must provide a voltage of 12V. When a motherboard using this chip is upgraded, it will cause a lot of trouble to ordinary computer users - it is too troublesome to open the case and change the jumper settings. The 29 series Flash ROM chip is relatively simple. Since it adopts a single voltage design and uses 5V voltage for reading and writing, reading and writing firmware can be completed using only software. In the motherboard manual, the motherboard manufacturer also lists the capacity of the Flash ROM chip, which has two capacity models: 1M and 2M. Here, the unit of "M" refers to "Mbit". The actual storage capacity of a 1M Flash ROM chip is 1Mbit=8*128Kbyte (1Byte=8bit), and the 2M chip is 256K. The above technical parameters can be distinguished by the number on the front of the chip. This number is marked strictly in accordance with the integrated circuit numbering rules. For example: the Flash ROM chip of Taiwan Winbond Company, the chip number is "29C020". The first two digits "29" indicate that this is a Flash ROM chip with 5V voltage reading and writing, and the following "020" represents a capacity of 2Mbit. For example, the Flash ROM chip produced by Intel has the chip number "28F010", which shows that the chip is a 5V read, 12V write, Flash ROM chip with a capacity of 1Mbit.

How to set up virtual memory
My computer--right-click--properties--advanced---performance point settings--advanced--most The following virtual memory

Virtual memory uses part of the hard disk space as memory. When the memory is used up, the computer will automatically call the hard disk to act as memory to relieve memory tension.

It is better to store the virtual memory on a disk with larger remaining space.(It is not recommended to place it on the system disk)

If the physical memory is 256, set the virtual memory to 2-3 times

If the physical memory is 512, set the virtual memory to 1.5-2.5 times

If the physical memory is 1G, set the virtual memory to 1-2 times

If you often run large programs, you can set it higher

Shut down necessary processes

If possible, it is best to add a memory stick, haha

Nine reasons and solutions for the system prompting "Insufficient memory"

1. The clipboard takes up too much memory

2. There are too many open programs

If there are too many documents open at the same time or too many programs are running. more, there won't be enough memory to run other programs. At this time, for multiple document interface (MDl) programs, such as Word, Excel, etc., please close all documents except the current document and exit the currently unused program. Then you may be able to continue the execution that was interrupted due to "insufficient memory" task.

3. Restart the computer

If you only exit the program without restarting the computer, the program may not be able to return memory resources to the system. Please restart your computer to free up system resources, and then run the program or perform the interrupted task again.

4. Too many programs that run automatically

If there are too many programs that run automatically when you start Windows, then even if you restart the computer, there will not be enough memory to use it. Run other programs.

5. Manage virtual memory settings

If there is no setting to let Windows manage virtual memory or disable virtual memory, the computer may not work properly or may receive "Insufficient Memory" message, or the same error message appears when running a program.

6. Increase available disk space

Since Windows uses hard disk space in the format of a virtual memory paging file to simulate RAM(), even though it has been set to let Windows manage virtual memory, memory, but when the drive where the virtual memory paging file is located (the hard disk partition where the Windows system is located by default) does not have enough space, an "out of memory" error will still occur. At this time, please perform one or more of the following operations to increase the available space on the drive where the Windows virtual memory paging file is located:

7. The program file is destroyed

If only When using a certain program, the system prompts that there is insufficient memory, while otherIf the program runs normally, then the likely cause is that the program file is corrupted, causing memory problems. However, Windows does not explicitly indicate that the program is damaged, so try deleting and reinstalling the program, and then re-running the program. If the system no longer prompts for insufficient memory, it means that the original program file is indeed damaged.

8. Use memory optimization software

There are many memory optimization software, such as RAM Idle and Memo Kit are two of the better ones. These software can be set to automatically clear the clipboard, release the memory that has not been released by closed programs, reorganize the Win386.swp file, etc., thereby saving you the trouble of manual operations and achieving the purpose of automatically releasing memory, you might as well give it a try!

9. Virus Checking

System infection with computer viruses is also the main culprit that causes insufficient memory. When the system has an "out of memory" error, please use the latest anti-virus software to check and kill it. Viruses, or after removing computer viruses, the "out of memory" problem is solved.
What is the best way to set up virtual memory
It is recommended that the initial size and maximum value of virtual memory be set to 1536MB. Setting the same value is to avoid fragmentation. It is best not to set it on the C drive, but set it on a drive with enough space. plate.

How to set up virtual memory:

(1) Properly set up virtual memory

The setting of virtual memory is mainly based on the size of your physical memory and the size of your computer. To set the purpose, right-click "My Computer" on the desktop and select "Properties" to see the memory. According to Microsoft's recommendations, the virtual memory is set to 1.5--3 times the physical memory capacity. For example, for 512MB of memory, the virtual memory is set to 768--1536MB; for 1G of memory, the virtual memory is set to 1536--3072MB. You can also let Windows automatically allocate and manage virtual memory, which can dynamically adjust the size of virtual memory based on actual memory usage. There is a recommended value at the bottom of the virtual memory settings page. If you really don't know what the optimal setting is, it is recommended that the virtual memory be set to the recommended value. Virtual memory has two values: initial size and maximum value. It is best to set the initial size and maximum value to be the same to prevent the system from frequently changing the size of the page file and affecting the operation of the computer. If the memory capacity is 2GB or more, you can also turn off virtual memory if you are not running large files or games.

Virtual memory is to use part of the hard disk space as memory when your physical memory is not enough. However, because the transmission speed of the hard disk is much slower than the transmission speed of the memory, using virtual memory is more efficient than physical memory. Be slow. The value you actually need should be adjusted multiple times by yourself. If the setting is too large, a large amount of fragments will be generated, seriously affecting theaffects the system speed. If it is set too small, it will not be enough, so the system will prompt you that the virtual memory is too small.

(2) Virtual memory setting method

Right-click "My Computer" and select "Properties--Advanced--Performance--Settings--Advanced--Virtual Memory- -Change", select the disk where the virtual memory is located, then click "Custom Size" below and enter "Initial Size" and "Maximum Value", and finally press the "Set" button, and then confirm. How to set virtual memory from C drive to other disks (if it is on other drives, the setting method is the same): Right-click My Computer--Properties--Advanced--Performance Settings--Advanced--Virtual Memory Change--Click C Drive--Single-select "No paging file"--"Settings", then the virtual memory next to the C drive will disappear; then select the D or F drive, single-select "Custom size"--"Initial size" below Enter values ​​into the two text boxes "" and "Maximum value" - "Settings" - OK - restart the computer to complete the settings.

It is best not to place the virtual memory on the same disk as the system. The memory changes dynamically with use. If it is placed on the C drive, it will easily cause disk fragmentation and affect the system running speed. Therefore, it is best to set the virtual memory on disks with large remaining disk space that are not commonly used, such as D and F. This can prevent the system from performing frequent read and write operations on the C disk and affecting the system speed. Virtual memory only needs to be set once on one computer and can be set on any disk.

(3) Reduce memory burden:

1. Do not open too many programs. If there are too many documents open or too many programs running at the same time, there will not be enough memory to run other programs, so you need to close unused programs and windows.

2. There should not be too many programs that run automatically. Click "Start" - "Run", type "Msconfig" - "OK", open the "System Configuration Utility" window, delete the startup items that you do not want to load automatically

㈦ How to set up the virtual memory of Windows 7 500g replacement disk with 3G memory to play large-scale stand-alone games

Your memory is basically enough (if you are not playing large-scale 3D) ) If you don’t know enough about how to set up virtual memory, please read the detailed introduction:
When the system is running, the required instructions and data must first be transferred from external memory (such as hard disk, floppy disk, CD, etc.) In the memory, the CPU reads instructions or data from the memory to perform calculations, and stores the calculation results in the memory. The memory plays the role of a "setter". When running a program requires a large amount of data and occupies a large amount of memory, the memory warehouse will be "filled up", and there is always a part of temporarily unused data occupying a limited space in this "warehouse", so this part must be "filled up" "Lazy" data is "please" out to make room for "active" data. At this time, you need to create another backup "warehouse" to store "lazy" data. Since the hard disk has a large space, the Microsoft Windows operating system selects the address of the backup "warehouse" on the hard disk. This backup "warehouse" is the virtual memory. By default, virtual memory is saved in the system partition of the hard disk as a swap file named Pagefile.sys.

Manually set virtual memory

In the default state, the system is allowed to manage virtual memory, but the management method of the system's default settings is usually conservative, which may cause problems during automatic adjustment. The page file is not continuous, and the reading and writing efficiency is reduced, and the work efficiency is not high, so prompts such as "insufficient memory" often appear. Let's set it up by ourselves.Leave it alone.

① Right-click the "My Computer" icon on the desktop and select the "Properties" option in the right-click menu that appears to open the "System Properties" window. Click the "Advanced" tab in the window to display the advanced settings dialog box.

② Click the "Settings" button in the "Performance" area, select the "Advanced" tab in the "Performance Options" window that appears, and open its dialog box.

③In this dialog box, you can see the area about virtual memory. Click the "Change" button to enter the "Virtual Memory" setting window. Select a partition with a large free capacity, check the check box in front of "Custom size", fill in the specific values ​​​​in the "Initial size" and "Maximum value" columns, and then click the "Settings → OK" button. Yes, finally restart the computer to make the virtual memory settings take effect.

Suggestion: You can divide a small partition specifically for virtual memory, IE temporary file storage, etc. In the future, you can perform disk defragmentation on this partition regularly, so as to better improve the computer's work efficiency.

1. Tailor-made virtual memory

1. Common setting method

According to the general setting method, check the virtual memory swap file Both the minimum and maximum values ​​can be set to 1.5 times the memory capacity. However, if the memory itself has a relatively large capacity, such as 512MB, the space it takes up is also considerable. So you can set the basic value of virtual memory like this: if the memory capacity is below 256MB, set it to 1.5 times; if it is above 512MB, set it to half of the memory capacity; if it is between 256MB and 512MB, set it to the same memory capacity. Same value.

2. Precise setting method

Since the applications that everyone actually operates cannot be the same, for example, some people want to run large programs such as 3DMAX, Photoshop, etc., while some people You may just be typing or playing some games, so your virtual memory requirements are different, so you need to accurately set the value of the virtual memory space according to local conditions.

① First set the customized "initial size" and "maximum value" of the virtual memory to the same two values, such as 500MB;

② Then open the "Control" in sequence Panel→Management Tools→Performance", in the "Performance" dialog box that appears, expand "Performance Logs and Alerts" in the left column, select "Counter Log" under it, and right-click in the blank space in the right column. Select the "New Log Settings" option in the right-click menu;

③ Fill in any name in the "Name" column of the pop-up dialog box, such as "Virtual Memory Test". Click the "Add Counter" button in the window that appears to enter the next window;

④Open in this windowIn the drop-down list of "Performance Object", select "Paging File", check "Select counter from list", and select "%Usage Peak" in the column below; check "Select example from list", in Select "_Total" in the column below, and then click "Add → Close" to end;

⑥ In the right column, you can find an additional "Virtual Memory Test" item, if the item is red It means that it has not been started yet. Click this item and select the "Start" option in the right-click menu;

Next, run some of your commonly used applications. After running for a period of time, enter the location where the log file is located. In the default directory "PerfLogs" under the system partition, find "Virtual Memory Test_000001.csv" and open it with the Notepad program. In the content, check the penultimate value in each column. This value is the usage ratio of virtual memory. , find the maximum value of this value, such as "46" in the picture, multiply 46% by 500MB (the virtual memory value set previously), and the resulting value is 230MB.

Use this value to set the initial size to 230MB, and the maximum value can be freely set according to the size of the disk space. It is generally recommended to set it to 2 to 3 times the minimum value. In this way, you can make the virtual memory more accurate and make your machine run smoother and more efficiently

2. Windows virtual memory acceleration secrets

Virtual memory This is very important for any version of Windows. If set up properly, it will greatly improve the performance and speed of your computer. However, by default, Windows always sets virtual memory to 1.5 times the physical memory. In this case, if the user installs 2GB of memory, the system will free up up to 3GB of hard disk space as virtual memory. But judging from the memory needs of current mainstream application software and games, there is no need to use so much virtual memory. So, are there any secrets or tricks that can make virtual memory use more efficient or perform better?

1. Split the virtual memory into multiple hard drives

Being on a faster hard drive does make virtual memory operate more efficiently. However, if the two hard disks on the computer are equally fast, the virtual memory should be evenly distributed on two different hard disks (not different partitions of the same hard disk). Because synchronous read and write operations will more effectively improve the overall virtual memory performance of the system.

For example, suppose you originally set up 700MB of virtual memory on hard disk C. Now you can try to reallocate it, that is, change hard disk C to 350MB and add 350MB of virtual memory to hard disk D. Theoretically, this will speed up the overall read and write operations of the virtual memory.

2. The hard disk requiresHave enough space

If you are not a very experienced computer user, or do not have special usage requirements, select the "system managed size" method in Windows XP to automatically handle virtual memory. Generally speaking, It should be safer and more stable than choosing the "custom size" method. However, one thing you must pay attention to is that since the "page file" (pagefile.sys) of virtual memory will shrink and expand as the computer is used, paging must be ensured in order for the system to manage virtual memory smoothly and more flexibly. The hard drive where the file is located has sufficient free space.

3. The minimum value is equal to the maximum value

Select the "custom size" method to deal with virtual memory, and set both the maximum and minimum values ​​to the same value. Many people believe that handling virtual memory in this way can help improve system performance. Their reasoning is that when the maximum and minimum values ​​are equal, the system does not need to shrink and expand the page file all the time. By eliminating these tasks, system efficiency is improved accordingly.

Many people firmly believe that this method is effective, but similarly, some people point out that it is not actually effective. But no matter what, if you want to set the maximum value and the minimum value equal, you must adhere to one principle, that is, the size of the virtual memory must be sufficient, otherwise the system efficiency will decrease (more copy operations will be required to free up the system). space), in severe cases, it will cause system instability.

4. Organize page files

If file data is stored on the hard disk for a long time, file fragments will naturally occur. To maintain or improve the working efficiency of the hard drive, defragment the hard drive from time to time. The so-called virtual memory is actually a data file on the hard disk, so should virtual memory also need to be organized like ordinary files?

The way Windows system handles page files (i.e. virtual memory) is different from ordinary document. In contrast, page files are less fragmented than regular files, and defragmentation of page files is usually not necessary. In fact, when Windows XP defragments the disk, the page file is not involved.

Although Windows does not defragment the page file, in fact the page file also has fragments. Friends who pursue "perfection" may still want to defragment the page file. You may wish to try the following method:

Right-click the "My Computer" icon on the desktop and select "Properties" in the function menu that appears. Enter the setting window of the system properties, use the mouse to click "Advanced" --> "Performance" --> "Settings" --> "Advanced" --> "Change", and in the "Virtual Memory" setting window that appears subsequently Check "No paging file"One item. Finally click the "Settings" button to exit and restart your computer.

After restarting, check whether the pagefile.sys page file still exists in the root directory of the disk, and delete it if it exists. After clearing the virtual memory page file, now defragment the disk. After completion, follow the previous steps to reset a certain amount of virtual memory and start the computer to make it effective. After being processed by the above method, the newly obtained page file will be fragment-free.

In addition, if you want to check the specific situation of page file fragmentation? Start the disk defragmentation program, conduct an "analysis" for the hard disk with page file, and then click "View Report" to see The "Page File Fragmentation" column will be clear at a glance.

5. The ideal size of virtual memory

If you want to use the "custom size" method to deal with virtual memory, what should you do? How much virtual memory should be set? In Windows XP, if the virtual memory is defined by the operating system itself, the system usually sets the minimum value to 1.5 times the physical memory. When expanded, the maximum value is between 2.5 and 3 times the physical memory. Under normal circumstances, if users want to customize the size of virtual memory, they can refer to this ratio setting.

Do we really need to refer to this ratio? If the computer has 1GB of memory, is it possible that the minimum value should be set to 1.5GB and the maximum value should be 2.5 to 3GB. Thus. The Pagefile.sys page file should be at least 1.5GB, which is too unrealistic!

Actually, compared with systems with small memory, systems with large memory have different standards when setting up virtual memory.

If you have more than 512MB or even 1GB of memory, since the physical memory is already quite sufficient, the required virtual memory should be reduced. Therefore, in a system with large memory, the minimum value of virtual memory can be set to half of the physical memory. For example, if there is 1GB of memory, the minimum value of virtual memory is set to 512MB, and the maximum value is maintained at 3GB in case of emergency. Note: Although the maximum value is set to 3GB, the system will not immediately appear a 3GB pagefile.sys file. In fact, it will first appear with the minimum value, and will increase when expansion is needed.

In addition, some friends with large memory may simply not set up virtual memory to force the system to use faster memory. In fact, this is not a wise approach. As the saying goes, don't do anything too absolute, even if you don't have virtual memory at all. The reason is that many applications require the use of virtual memory during design. Without it, the system will become unstable or crash.

As for systems with small memory, such as 256MB, the setting ratios of 1.5x and 3x are the most stable. That is, the minimum value of virtual memory is set to 384MB, and the maximum value is 768MB.

6. The most accurate hand-customized virtual memory

0.5 times, 1.5 times, 3 times, wow! It’s like buying clothes in large, medium and small sizes, no personality at all . Is there a more "custom-tailored" way to set up virtual memory?

Enter perfmon.msc in "Start" → "Run" on the Windows XP desktop, a monitor related to system performance will Will appear. Look at the bottom of the display, there are three counters (pages/sec, Avg.Disk Queue Length and processor Time,). In order to facilitate accurate monitoring of the virtual memory page file, please click on these three counters one by one and press the Delete key on the keyboard to delete them. Please rest assured that after deletion, these three items will reappear the next time you start the System Performance Monitor.

After deleting, please right-click the center of the chart, select "Add Counter" in the function menu that appears, and then select "Performance Object" in the pop-up window. "Process". Then click "Page File Bytes" in the "Select from List" column. I don’t know what “Page File Bytes” means. Just click the “Description” button and the explanation text will appear under the dialog box.

After selecting "Page File Bytes", select the "Total" item in the "Select Example from List" column on the right, and then click the "Add" and "Close" buttons in sequence. A counter named "Page File Bytes" will appear below Performance Monitor.

Repeat the above actions and add a counter named "Page File Bytes Peak" (ie, Page File Bytes Peak under Process).

Now, look back at the monitor. The chart should be showing and counting the two newly added counters. If nothing unexpected happens, the display of these two counters on the chart is incorrect, that is, the values ​​are close to the highest ratio line and there is no dynamic change. Don't be afraid, this does not mean that there is something wrong with your computer, but that the chart scale is not set appropriately! Use the right mouse button to click the "Page Fele Bytes" and "Page File By8tes Peak" counters at the bottom of the monitor one by one. And select the "Properties" item. Change the "Scale" column on the "Data" page to 0.0000001, so that the chart in the display is no longer silent.

If you have read the instructions provided by the system, I believe you should know "Page File Bytes" and "Page File Bytes Peak" exactly represents the virtual memory used during system monitoring and its peak value. Therefore, you need to accurately manually set the virtual memory. You can refer to the number shown below the chart, the unit is Bytes.
< br />Want to know how much virtual memory your system will consume under normal circumstances? Please start the applications you usually use daily and let them start working, and then look at the values ​​displayed on the performance monitor. You know.

There are always times when people are crazy and want to know how much virtual memory the system needs when they use the computer crazily. Now just start and run the programs on the computer (for example, open more than ten programs) Use an IE browser window to surf the Internet, play MP3 and DVD videos, and then burn discs or compress DV videos to see how much the monitor percentage will increase.

Right-click the mouse on the chart , click "Properties", enter the "Chart" page and check the "Horizontal Grid" item. In this way, horizontal dividing lines will appear in the chart. Is it easier to distinguish?

In the chart The red vertical line runs too fast and it is too late to open the program on the computer for testing?

Similarly, right-click on the chart, select "Properties", and click "Auto Sampling Interval" on the general page Change 1 second to 5 seconds in one item. At this time, the "Graphic Time" value in the chart will change from 1 minute and 40 seconds to 8 minutes and 20 seconds. In other words, it takes 8 minutes and 20 seconds for the red vertical line to complete a circle Seconds, this time should be enough for you to open and run many applications, and then slowly check the results in the chart.

Finally, through the monitor chart, I believe you can already roughly estimate your computer How much virtual memory should be set in the system.

3. Several possibilities for "insufficient virtual memory"

1. Infection with viruses

Some When a virus attacks, it will occupy a large amount of memory space, causing the system to have insufficient memory problems. Quickly kill the virus, upgrade the virus database, and then take anti-virus measures!

2. Improper virtual memory settings

Improper virtual memory settings may also lead to insufficient memory problems. Generally, the virtual memory size is 2 times the physical memory size. If it is set too small, it will affect the normal operation of the system program. Readjust The virtual memory size takes WinXP as an example. Right-click "My Computer", select "Properties", then on the "Advanced" tab, click the "Settings" button in the "Performance" box, switch to the "Advanced" tab, and then Click the "Change" button in the "Virtual Memory" box, then reset the virtual memory size, and then restart the system.

3. Insufficient system space

The default virtual memory file isIn the system disk, for example, the virtual memory file name of WinXP is "pagefile.sys". If the remaining space of the system disk is too small, resulting in insufficient virtual memory, the problem of insufficient memory will also occur. At least 300MB of remaining space must be reserved on the system disk. Of course, this value should be determined based on the actual needs of the user. Users should try not to install various application software in the system disk to ensure that there is enough space for virtual memory files, and it is best to place virtual memory files in non-system disks.

4. Because the SYSTEM user permissions are improperly set

When a Windows system based on the NT kernel is started, the SYSTEM user will create a virtual memory file for the system. For the sake of system security, some users use the NTFS file system, but they cancel the "write" and "modify" permissions of the SYSTEM user on the system disk. In this way, they cannot create virtual memory files for the system. When running large programs, problems will also occur. Insufficient memory problem. The problem is easy to solve, just give the SYSTEM user "write" and "modify" permissions again, but this is only limited to users using the NTFS file system.

4. Optimization of virtual memory

1. Enable disk write cache

Right-click on "My Computer" and select " Properties->Hardware", open the Device Manager, find the hard disk currently in use, right-click the mouse and select Properties. In the "Policy" page of the hard disk properties, turn on "Enable write caching on disk".

This option will activate the hard disk's write cache, thereby increasing the hard disk's read and write speed. However, please note that after this function is turned on, if the computer suddenly loses power, it may cause irreparable data loss. Therefore, it is best to turn on this function when there is a UPS. Of course, if you don’t perform any important data processing work when using your computer, it doesn’t matter if you don’t have a UPS. This function will not cause much damage to the system.

2. Open Ultra MDA

Select "Basic/Secondary IDE Controller" in IDE ATA/ATAPI controller in device management, right-click and select " Properties" to open the Advanced Settings page. The most important setting item here is "Transfer Mode", generally "DMA (if available)" should be selected.

3. Configure recovery options

When Windows XP encounters a fatal error during operation, it will save a snapshot of the memory as a file for system debugging. For most ordinary users, this file is of little use and will instead affect the performance of virtual memory. So it should be turned off.

Right-click on "My Computer"key, select "Properties->Advanced", click the "Settings" button under "Performance", and select the "Advanced" page in "Performance Options". There is a "Memory Usage" option here. If it is set to "System Cache", Windows XP will use about 4MB of physical memory as a cache for reading and writing to the hard disk, which can greatly improve the data exchange between physical memory and virtual memory. speed. By default, this option is turned off. If the computer's physical memory is sufficient, such as 256M or more, it is best to turn this option on. But if physical memory is tight, you should still keep the default options.

Page file settings

1. Calculation of page file size

For different computers, the size of the page file is different. of. Regarding the setting of the page file size, there are two widely circulated "formulas", "physical memory X2.5" or "physical memory X1.5". Although these two calculation methods are simple, they are not suitable for all computers. The most accurate way to set the page file size is to look at the actual page file size used by the computer in normal operation.

Using the log function that comes with Windows XP, you can monitor the size of the page file that your computer usually uses, so as to make the most accurate settings. The specific steps are as follows.

1. Right-click on "My Computer", select "Properties->Advanced", click the "Settings" button under "Performance", then select the "Advanced" page, click Click the "Change" button under "Virtual Memory". Select "Custom size" and set both "Start size" and "Maximum value" to 300M. This is only a temporary setting. After the settings are completed, restart the computer for the settings to take effect.

2. Go to "Control Panel->Performance and Maintenance->Management Tools" "Performance" "Performance Logs and Warnings" "Counter Logs". Right-click on the right side of the window and select "New Log Settings"

3. Set a log name at will, such as "Monitor Virtual Memory Size".

4. Click the "Add Counter" button on the "General" page.

Select "Paging File" in "Performance Objects", then select "%Usage Peak" under "Select Counters from List", and in the "Select Examples from List" on the right Select "_Total". Finally click the "Add" and "Close" buttons.

5. Don’t forget to remember the storage location and file name of the log file in the “Log File” page. You will need to check this log later to determine how much virtual memory Windows XP usually uses. In this example , the log files are stored in D:\Perflog directory.

In addition, set the "Log File Type" to "Text File" to make it easier to read.

At this time, you can see that the icon in front of the newly created log entry turns green, which indicates that the logging system is already monitoring the virtual memory. If the icon is still red, you should right-click and select "Start" to start the log.

After a while, open the CVS file and you will see the following entries.

This log file records the usage of the page file during this period. Note that the unit here is %, not MB. Through simple calculation, you can get the minimum size of the page file. The formula is "page file size X percentage". For example, in this example, the maximum usage ratio of virtual memory is 31%, 300MBX31%=93MB, this value is the minimum value of virtual memory (note that 300MB is the temporary value of the previous setting).

If the physical memory is large, you can consider setting the "Start Size" and "Maximum Size" of the page file to be equal, equal to the size calculated in the previous step. In this way, the hard disk will not be fragmented due to excessive expansion of the page file. The side effect is that because the "maximum value" is set to a smaller value, in case of accidental virtual memory overrun, it may cause the system to crash.

Set the page file

Now go back to the "Virtual Memory" settings dialog box, select the custom size and set the "Initial Size" and "Maximum Size" respectively according to the calculation results above. value". Here, the "Initial Size" is set to 91M, and the "Maximum Size" is set to 200M, which is safer.

Defragment the page file

Windows XP requires a large amount of access to the page file when running. If the page file becomes fragmented, system performance will be seriously affected and the hard disk will be shortened. service life. Therefore, it is necessary to defragment the page file regularly.

But don’t forget that the page file is a key system file and cannot be accessed when Windows XP is running. So defragmenting it is not an easy task. There are two options to choose from. One is to install Windows dual system, and then start another Windows to defragment the partition where Windows XP is located. The second is to use specialized tool software, such as System File Defragmenter, etc.
Hope this helps! ! !

Right-click "My Computer" - Properties - Advanced He Zao - click "Settings" under "Performance" - click "Advanced" - click under "Virtual Memory" "Change" - click "Custom size" - set the maximum and minimum values ​​according to your actual situation
(I have 256 memory, set the minimum value to 512M and the maximum value to 1024M) - you can also change them
Set them to 2-3 times the actual memory (assuming the actual memory = or less than 256M) - click Settings - Confirm 3 times - Restart.

Question 2: How to modify What is the size of your computer's virtual memory? Right-click "My Computer", left-click "Properties" --- "Advanced" -- "Performance (Settings)" --- "Advanced" -- "Virtual Memory (Change)" ---"Custom size (setting)" can be set to 1.5 or 2 times the physical memory value according to the size of your physical memory. Generally, you can use the system's default size. If the system often prompts you that the virtual memory is small, then You can set the value a little larger, but not too big. It also depends on the remaining capacity of your system disk. Of course, you can also transfer the paging file "virtual memory" to other partitions. Click on the partition you want to set. If If you want to transfer the paging file to the "d" drive, just click "d", set the virtual memory value and click "OK" (need to restart).

Question 3: My computer Memory 4G, how to set virtual memory. Generally speaking, 4G does not require virtual memory, but...
Generally speaking, it is said that virtual memory is 1.5 to 2 times the actual memory, so 4G is set to 1.5 to 2 times. It is too big, so you set it to 2G first. If it is still tight, set it to 4G.
Generally speaking, virtual memory is not set under the C drive

Right-click [My Computer]-[Properties]-[General] tab. The pink line in the picture below is the physical memory information.

Question 6: How to set the computer virtual memory. It is best to set the initial size and maximum value to 1-2 times your physical memory. For example, 1G is set to 2048MB (1G memory is 2 times). 2G is set to 4096MB (2G memory is 2 times), 3G is set to 4608MB (3G memory is 1.5 times), 4G memory is set to 4096MB first (1 times 4G is not enough), if your physical memory is less than 2G or 2G , it is recommended to upgrade your physical memory (the initial size and maximum value settings must be consistent).
How to set virtual memory: Right-click My Computer/Properties/Advanced/Performance Settings/Advanced/Change in Virtual Memory/Select Custom Size, set the initial size and maximum value at the same time to your physical 1-2 times the memory. If your memory is 1G, set both the initial size and the maximum size to 2048MB. After setting, you need to press the "Set" button, then click OK and Apply to restart the computer and the settings will take effect.
Right-click Computer/Properties/Advanced System Settings/Advanced/Performance/Settings/Advanced/Virtual Memory Change/Enter the adjustment interface (it’s almost the same as the Win7 system mentioned above)
You didn’t mention your memory How big is it? Please refer to the settings above.Can.

Question 7: How to set the virtual memory of win7 4g memory? It is best not to be so large at all. The virtual memory is used as a supplement to the physical memory. The speed is limited. If it is set too large, it will not have much effect. It is usually set on the C drive. That's it. No need to set it for other disks. The physical memory you are using now has 4G. It is recommended to set the initial size to 1024 and the maximum value to 4096. If this prompts insufficient memory, you should consider adding more memory.

Question 8: How to set up computer virtual memory. If your system disk space is enough, you don’t need to consider virtual memory and its storage location. Because your physical memory is large enough, the virtual memory usage is very low. Of course, if you place the virtual memory in a location other than the system disk, it will slightly speed up the system and slightly extend the life of the hard disk. To set virtual memory, right-click "My Computer"->Properties->Advanced->Performance->Settings->
Advanced->Virtual Memory->Change, you will find that the system has a default value, the default The value is generally 1.5 times to 3 times the physical memory. That is, the minimum is 1.5 times and the maximum is 3 times. Just use the default one. Then click on another partition to set it. For example, if you want to store the virtual memory on the E drive, you click on the E drive and set the minimum and maximum values. Then set the original virtual memory of the c drive to empty, that is, select "No paging file". Save and exit, the system requires a restart. After restarting, the virtual memory is placed on the E drive. To check, you can display all hidden files (including system files), go to the E drive to see if there is "pagefiles.sys", this is the virtual memory file.

Question 9: How to set up computer virtual memory. Taking the win7 system as an example, right-click on the computer, properties, advanced system settings, performance>settings, advanced, virtual memory>change, automatic management Cancel, customize size, set, confirm, exit and restart.
