4G memory supported by 32-bit systems (Vista/XP only)

I believe many of my friends will be eager to increase the memory in the near future. After all, the memory is much cheaper,
However, we all use 32-bit systems (Vista/XP). Generally, we can only recognize 3G memory,
So, how can we avoid wasting extra memory? (how can we afford it if it is cheap)
The younger brother found some related onlineArticleAnd finally found some mitigation methods.
Let's share it with you.

In theory, the 32-bit operating system fully supports 4 GB memory, and of course 4 GB is also the 32-bit System Support limit.
If the middleware uses 4 GB or above, we recommend that you use a 64-bit system.

First, check whether the motherboard is supported. Download the Everest detection software and right-click to use thunder to download it.
In the motherboard-memory option, physical address extension (PAE) checks whether "operating system support" and "processor support" are "yes ",
If it is "yes", it means that the motherboard supports (such as 001); if it is "no", it means that the motherboard does not support it. You don't need to look at the following.


Windows XP users:
Right-click "my computer" and click "properties-advanced-start and fault recovery-set-edit"
Find the following content in the pop-up Notepad:
\ Windows = "Microsoft Windows XP Professional"/noexecute = optin/fastdetect

Add "/PAE" to "icrosoft Windows XP Professional:
\ Windows = "Microsoft Windows XP Professional"/PAE/noexecute = optin/fastdetect"

Save and close.

Windows Vista users:
Click Start> AllProgram"-" Attachment "; right-click" command prompt "click" Run as administrator"
In the command line window, enter the following command and press Enter:
Bcdedit/set PAE forceenable

After the computer is restarted, the word "physical address extension" is added below the computer attribute. Although the display is still GB memory, 4G memory is actually fully enabled, but how can we prove this? Use the ramdisk virtual hard disk software for testing.

Ramdisk is a small software that converts memory into virtual hard disks. The memory speed is dozens of times faster than that of hard disks. Therefore, when I process PS and other software that requires a large number of temporary storage disks, usually, it is used as a temporary storage disk of the software, so the speed of the software will multiply. when the system does not enable PAE, it can only identify the GB memory, using ramdisk will directly occupy the GB of memory. After you enable PAE, you can use ramdisk to set the MB memory as the virtual hard disk and call up the Task Manager. The memory usage is not reduced, that is, the 768 MB memory called by ramdisk is the MB memory not displayed by the system. In other words, the system has found 4 GB memory.
