How to properly set the virtual memory of Windows 7

The optimal value of virtual memory is 1.5-3 times the memory capacity.

Answer: Wrong! It should be judged according to the actual use. Especially the popularity of large memory today. Memory usage See the task manager's memory column.

Generally 512MB of memory, according to the actual memory usage, you can set the virtual memory to 256-768MB (the sum of memory + virtual memory is generally 256MB higher than the normal occupancy).

1GB memory, according to the actual memory usage, you can set the virtual memory to 128-1024MB (the sum of memory + virtual memory is generally 256-512MB higher than the normal occupancy). Usually, people who normally occupy hundreds of megabytes (most of them) can even disable virtual memory (software-limited software can set a small amount of virtual memory, such as 16-128MB).

Memory is 2G and above, you can generally disable virtual memory (software limited to a small amount of virtual memory, such as 16-128MB). Some people who do use a lot of memory, such as playing large 3D games, making large pictures, 3D modeling, etc., and receiving the system memory shortage warning, need to set the virtual memory as appropriate.

Three: The bigger the virtual memory, the better.

Answer: Wrong. The virtual memory is too large, which wastes disk space, increases the time for head positioning, and reduces system execution efficiency without any benefit. Correct setting can save 256MB-4G space (depending on memory size)

3, virtual memory optimization

Generally, you can disable virtual memory first, restart computer
into security Mode (do not run a lot of programs at this time), and then defragmentation, reset virtual memory after completion, so that the page file is free of fragmentation and read and write faster.

4, virtual memory settings

Take WIN7 as an example, computer right, properties, advanced system settings, performance > settings..., advanced, virtual memory > change..., Automatic management cancel, custom size, set, OK, exit restart.
