一个程序的RAM更多 [英] More RAM for a program

问题描述

我听说过Microsoft Windows为程序提供2 GB的RAM，为Windows后台操作提供2 GB的RAM。如果您想为程序提供更多RAM，则需要使用所谓的"/ 3"。切换到让你的计算机给3GB程序和1GB
windows后台操作。我想知道这是否属实，如果是，那么为什么主板允许你在你的PC上安装超过4GB的RAM，因为其余的什么都不做，如果它不是真的，我该如何为程序分配更多的RAM或
a sir-tan程序？

I have heard that Microsoft Windows gives 2 GB of RAM to programs and 2 GB to windows background operations. If you want more RAM for your programs you need to use the so called "/3" switch to make your computer give 3GB to programs and 1GB for windows background operations. I want to know if this is true and if it is, then why does a motherboard allow you to install more then 4GB of RAM on you PC because the rest will just do nothing and if its not true how do I allocate more RAM to programs or a sir-tan program?

推荐答案

是的，确实为用户模式分配了2 GB而另一个用于Windows核心操作。对于32位系统也是如此，通过在boot.ini中使用/ 3GB开关来为您的用户模式应用程序获取更多RAM; ie; 你可以改变这种行为。这个
也取决于你的操作系统。

Yes, It is true that 2 GB is assigned to usermode and the other 2 is for windows core operations. This is true for 32 bit systems also by uising the /3GB switch in boot.ini to get more RAM to you user mode apps; ie; you can alter this behaviour. This is dependent on you OS too.
