The WinXP system breaks through 4G to have the wonderful recruit

1, first check whether the motherboard support, download Everest detection software, in the motherboard-memory one, physical address Extension (PAE) to see "Operating system support" "Processor support" is "yes", if it is "no" on behalf of the motherboard does not support, At the system level, the effort is futile; if it is "yes", "activity" is a "no" and can be modified.

2, turn on my Computer-Properties-advanced-Startup and recovery-settings-edit, here the edit operation is the C-packing directory hidden under the Boot.ini file, you can also directly edit the system disk file, the contents of the file are as follows:

[boot loader]

Timeout=5

Default=multi (0) disk (0) rdisk (0) partition (1) WINDOWS

[Operating Systems]

multi (0) disk (0) rdisk (0) partition (1) windows= "Microsoft WINDOWS XP Professional"/noexecute=optin/fastdetect

3, then in "multi (0) disk (0) rdisk (0) partition (1) windows=" Microsoft WINDOWS XP Professional "/noexecute=optin/fastdetect" The "Microsoft Windows XP Professional" that indicates the operating system plus "/PAE" is "multi (0) disk (0) rdisk (0) partition (1) windows=" Microsoft Windows XP rofessional "/pae/noexecute=optin/fastdetect", save shutdown, the system starts again will open PAE.

4, after the restart, the computer properties of the lower part of the "Physical Address extension" a few words, although the display is still 3.25g of memory, but in fact 4g memory has been fully enabled, you can use RAMDisk virtual hard disk software to test. RAMDisk is a small software that converts memory into a virtual hard disk. In the system does not open the PAE can only recognize 3.25g memory, use RAMDisk will directly occupy the 3.25g of memory, and after the PAE, with RAMDisk set 768MB memory as a virtual hard disk, and then pull up Task Manager, will find that memory usage is not reduced, that is to say, RAMDisk called 768MB memory is the system does not show the 768MB, that is, to solve the XP system limit 4g memory problem.
