WinXP system breaks through 4G memory constraints and has a trick

With enough memory space support, the system can run quickly, but under Windows XP system, this is a very distressing problem, only 3.25G of memory can be used in the system. In order to make the memory space bigger, in order to improve the system running speed, we must implement the Windows XP breakthrough 4G memory constraints.

WinXP system breaks through 4G memory control method:

1. First check whether the motherboard supports, download the everest detection software, in the motherboard-memory item, Physical Address Extension (PAE) view & ldquo ; Operating system support & rdquo; & ldquo; <; processor support & rdquo; whether it is "yes", if it is "no", it means that the motherboard does not support, the system level is no longer how hard it is; if it is "yes" is ” In the words, "activity" one is “no” there is also the possibility of modification.

2, open my computer - Properties - Advanced - Startup and Recovery - Settings - Edit, here the editing operation is the hidden boot.ini file in the root directory of the c drive, you can also directly edit to the system disk The file contents 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 the "multi(0)disk(0)rdisk(0)partition(1)\\WINDOWS=”Microsoft WINDOWS XP Professional" /noexecute=optin /fastdetect” “Microsoft WINDOWS XP Professional ”plus“/PAE” ie“multi(0)disk(0)rdisk(0)partition(1)\\WINDOWS=”Microsoft WINDOWS XP rofessional” /PAE /noexecute=optin /fastdetect”, save off The system starts again opens PAE.

4, after restarting, the computer attribute is more than "physical address expansion", although the display is still 3.25g 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. When the system does not open PAE and only recognizes 3.25g memory, using ramdisk will directly occupy the 3.25g memory. After turning on PAE, set 768mb with ramdisk. Memory as a virtual hard disk, and then call out the task manager, you will find that the memory usage has not been reduced, that is to say, the ramb memory called by ramdisk is 768mb which is not displayed by the system, which solves the problem that xp system limits 4g memory.

The above content is the way Windows XP system breaks through 4G memory constraints. Looking at the dense English letters will make you feel that the method is difficult. Actually it is not. Just add a word and then pass the ramdisk virtual hard disk software. To test, you can complete the operation. The method is quite simple. Users who need it can set it up by themselves.
