Regarding the system virtual memory problem, what does the system virtual memory value mean is too l

It's about a double of the computer's real memory.

What is virtual memory.

Virtual memory is a hard disk space that is used as memory to make up for the lack of RAM space on your computer. When the actual RAM is full (in fact, before the RAM is full), the virtual memory is created on the hard disk. When the physical memory is used up, the virtual memory manager selects the low-priority portion of the memory that has not been used recently and writes it to the swap file.

This process is hidden from the application, which treats the virtual memory as the same as the actual memory.

Technical details: For Intel IA-32 processors (including 386, Pentium, etc.), the memory address of the user application (process) accessing memory is virtual, and the CPU converts it to the actual physical memory address. When there is not enough physical memory, the operating system swaps out a portion of the memory that is not used in each process for the time being to a page file (swap file), and swaps the contents of programs that need to access the memory from the page file to the physical memory.

This paragraph] the role of virtual memory.

I don't know if you have noticed,In the windows2000 (XP) directory there is a system file called (windows98 under it,Its size often changes by itself,When it is small, it may only be tens of megabytes,When it is large, there are hundreds of megabytes,This irregular change really makes many people scratch their heads。 In fact, it is a virtual memory under Windows, its role is basically similar to physical memory, but it exists as a "reserve force" of physical memory, that is, it will only play a role when physical memory is no longer enough.

It's up to you to find it yourself! <>

Your hard drive has enough space for you to set up your own virtual memory, and the steps are as follows:

Right-click on My Computer Properties Advanced Performance Settings Advanced Virtual Memory Changes Select the partition where the virtual memory (page file) is stored Custom size Determine the maximum and minimum settings.

Generally speaking, virtual memory is a double of physical memory, a little larger is fine, and if you don't want the virtual memory to change frequently, you can set the maximum and minimum values to the same.

1. This is because the virtual memory of the system is set a little low.

2. It is recommended to set the initial size and maximum value to 1-2 times of your physical memory at the same time, such as 1G set to 2048MB (1G memory is 2 times), 2G set to 3072-4096MB (2G memory is doubled), 3G set to 3072-4608MB (3G memory is doubled), 4G memory is set to 4096 (1 time of 4G is not enough to add), if your physical memory is less than 2G or 2G, It is recommended to upgrade your physical memory (the initial size and maximum settings should be the same).

3. How to set up virtual memory: right-click on My Computer Properties Advanced Performance Settings Advanced Changes in Virtual Memory Select a custom size, set it to 1-2 times your physical memory at the initial size and maximum value at the same time. If you have 1GB of RAM, set both the initial size and the maximum to 2048MB.

After setting, you need to press the "Settings" button, and then press OK and Apply, restart the computer and the settings take effect (there is no fixed number to set the size of virtual memory, and the size can be adjusted.) For example, if your physical memory is less than 512, the virtual memory can be set to be larger such as "three times").
