How to Enable PAE on 32-bit Windows Vista for 4 GB or More Memory如何啟用PAE的32位Windows Vista的4 GB或更多的內存

Intel introduced the 36-bit physical addressing mode called PAE (Physical Address Extension, read英特爾推出了36位物理尋址方式所謂的PAE （物理地址擴展，閱讀 Wikipedia reference維基百科參考 or或 MSDN reference的MSDN參考 ) since Intel Pentium Pro processor to allow 32-bit operating systems to use more than 4 GB of physical memory. ）以來，英特爾的Pentium Pro處理器，讓32位元作業系統使用4 GB以上的物理內存。 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.不過，即使與x86或x86的x64的PAE支持的CPU處理器，在大多數的Windows系統， PAE是默認情況下禁用，用戶必須手動打開該PAE的支持，在作業系統，以便確認和使用超過4 GB的物理RAM內存，除Windows Vista的。

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.大量的技術支持和故障排除的網站Windows Vista的發布調整或提示，要求用戶手動啟用PAE支持在32位的Windows Vista與下面的命令使用4GB以上的記憶體。

According to據 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 ( “一台計算機上支持硬件啟用數據執行保護（ DEP ） ，並且是在運行32位版本的Windows作業系統支持的DEP ，自動啟用PAE時啟用DEP （ Data Execution Protection數據執行保護 , 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. ，啟用DEP默認情況下，在Windows Vista ） ，並在所有32位版本的Windows操作系統，除了Windows Server 2003 SP1的， PAE是殘疾人士當您禁用DEP的。 To enable PAE when DEP is disabled, you must enable PAE explicitly, by using /set nx AlwaysOff and /set pae ForceEnable.”要啟用PAE時， DEP的是殘疾人士，您必須啟用PAE明確，使用/設置NX的alwaysoff和/設置的PAE forceenable “ 。

Thus, PAE mode is always enabled by default in Windows Vista as it’s required for hardware-based DEP / NX.因此， PAE模式一直是啟用默認情況下，在Windows Vista ，因為它所需的硬件為基礎的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位客戶端版本的Windows Vista （也是Windows XP中）絕不會支持以上4 GB的地址空間，即使與PAE的啟用，另據 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內存限制在32位元Windows Vista是一個人造的軟件基於鎖放置的Windows Vista作業系統，以限制供應的部分記憶體大於4 GB ，在制度與主板支持4GB以上的價值物理地址空間。

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，許多用戶感到失望和困惑，即使後' ，使' PAE的支持在32位（ x86 ）的Windows Vista （其中，實際上是沒有必要） ，他們仍然無法看到全部4 GB的或以上（最系統的顯示，只有約3.5或3.25 GB的內存，由於一些內存地址空間被映射到使用作為儲備，為系統外設）的物理內存或RAM模塊安裝，雖然 Windows Vista SP1 Windows Vista的SP1的 can可以 correctly display正確顯示 the amount of installed memory (not memory available to use) up to 4GB in size.金額安裝的內存（不可用的記憶體使用）高達4 GB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，已知的僅有的方法，使支持的物理內存更大的超過4 GB的大小在Windows Vista 32位版本是使用 hack to replace the limitation files with copy from 32-bit Windows Server 2008哈克，以取代限制文件的副本由32位Windows Server 2008 , which supports and can see more than 4 GB memory. ，支持和可以看到， 4 GB以上的記憶。 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.不過，用戶使用入侵已處理一些後果，特別是產品激活的問題，除非你有執照或真正的產品密鑰用於Windows Server 2008 。
