How to Enable PAE on 32-bit Windows Vista for 4 GB or More Memory如何启用PAE的32位Windows Vista的4 GB或更多的内存

Intel introduced the 36-bit physical addressing mode called PAE (Physical Address Extension, read英特尔推出了36位物理寻址模式称为抗生素后效应（物理地址扩展，阅读 Wikipedia reference维基参考 or或 MSDN reference参考的MSDN ) since Intel Pentium Pro processor to allow 32-bit operating systems to use more than 4 GB of physical memory. ） ，因为英特尔奔腾Pro处理器，让32位元作业系统使用4 GB以上的物理内存。 However, even with x86 or x86-x64 PAE supported CPU processor, in most Windows system, PAE is disabled by default, and user has to manually turn on the PAE support in operating system in order to recognize and use more than 4 GB of physical RAM memory, with the exception of Windows Vista.但是，即使x86或x86的64位抗生素后效应支持CPU处理器，在大多数的Windows系统， PAE是残疾人默认情况下，和用户手动打开太平洋建筑工程公司支持的操作系统，以便确认和使用超过4 GB的物理RAM内存，除Windows Vista中。

A lot of technical support and troubleshooting sites for Windows Vista publishes a tweak or tip that asking user to manually enable PAE support in 32-bit Windows Vista with the following command to use more than 4GB of memory.很多技术支持和故障排除的网站为Windows Vista出版了尖调整或用户的要求，以手动启用PAE支持32位的Windows Vista与下面的命令使用超过4GB的内存。

BCDEdit /set PAE forceenable

According to据 MSDN Library article MSDN Library的文章 , “on a computer that supports hardware-enabled Data Execution Prevention (DEP) and is running a 32-bit version of the Windows operating system that supports DEP, PAE is automatically enabled when DEP is enabled ( ， “计算机上支持硬件启用数据执行保护（ DEP ）和正在运行32位版本的Windows操作系统，支持的DEP ， PAE是自动启用的DEP启用（ Data Execution Protection数据执行保护 , DEP is enabled by default in Windows Vista) and, on all 32-bit versions of the Windows operating system, except Windows Server 2003 with SP1, PAE is disabled when you disable DEP. ，环保局是默认启用Windows Vista中） ，并在所有32位版本的Windows操作系统，除了Windows Server 2003 SP1的， PAE是残疾人当你禁用DEP的。 To enable PAE when DEP is disabled, you must enable PAE explicitly, by using /set nx AlwaysOff and /set pae ForceEnable.”要启用PAE时的DEP是残疾人，你必须启用PAE明确，通过使用/设置NX的AlwaysOff和/太平洋建筑工程公司ForceEnable一套。 “

Thus, PAE mode is always enabled by default in Windows Vista as it’s required for hardware-based DEP / NX.因此， PAE模式始终是默认启用Windows Vista中，因为它是需要以硬件为基础的DEP / NX的。 And 32-bit client versions of Windows Vista (and also Windows XP) will never support more than a 4GB address spaces, even with PAE enabled, according to another和32位客户端版本的Windows Vista （也是Windows XP中）将不会支持超过4GB的地址空间，即使抗生素后效应启用，另一种 MSDN Library article MSDN Library的文章 . 。 Thus, 4 GB physical RAM memory limit on 32-bit Windows Vista is an artificial software based lock placed by Windows Vista operating system to limit the availability of the portion of memory larger than 4 gigabytes in a system with motherboard that support more than 4GB worth of physical address space.因此， 4 GB的物理RAM内存限制在32位的Windows Vista是一种基于人工智能的软件锁放在Windows Vista作业系统，以限制供应的部分记忆体大于4千兆字节的系统与主板，支持超过4GB价值物理地址空间。

Thus, many users disappointed and baffled that even though after ‘enabling’ PAE support in 32-bit (x86) Windows Vista (which in actuality is not necessary), they still cannot see full 4GB or more (most system showing only around 3.5 or 3.25 GB of memory due to some memory address space been mapped to use as reserve for system peripherals) of physical memory or RAM modules installed, although因此，许多用户感到失望和困惑，即使在'有利'太平洋建筑工程公司支持32位（ x86 ）的Windows Vista （这实际上是没有必要） ，但它们仍不能充分看到4GB或更多（最系统显示只有大约3.5或3.25 GB的内存由于一些内存地址空间被映射到用作储备系统外设）的物理内存或RAM模块安装，虽然 Windows Vista SP1 Windows Vista的SP1的 can可以 correctly display正确显示 the amount of installed memory (not memory available to use) up to 4GB in size.数额安装内存（不可用内存使用）高达4GB的大小。

Currently, the only known method to enable support for physical memory bigger than 4GB in size in Windows Vista 32-bit version is using the目前，已知的唯一方法，以使支持的物理内存大于4GB的大小在Windows Vista 32位版本使用的是 hack to replace the limitation files with copy from 32-bit Windows Server 2008黑客，以取代限制文件的副本从32位Windows Server 2008的 , which supports and can see more than 4 GB memory.支持并可以看到4 GB以上的内存。 However, user using the hack has to deal with some consequences especially product activation issue, unless you have license or genuine product key for Windows Server 2008.然而，用户使用黑客已处理一些后果是产品激活的问题，除非你有执照或真正的产品金钥的Windows Server 2008年。
