How to set Windows 7 system virtual memory tips

First: Virtual memory should not be set on the system disk C disk (the system disk is the same as other disks), but should be located in other non-system partitions.

Answer: Wrong! Because C disk is the default system disk, the most frequently read and write system files and paging files. And what is the most time-consuming operation for hard disk reading and writing? It's the head position! The head positioning in the same section is definitely better than the long distance back and forth of the partition. Therefore, the virtual memory (system default) within the system disk is the fastest and most efficient.

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

Answer: Wrong! To be judged on the basis of actual use. Especially the large memory popularity today. Memory usage See the Task Manager's memory column.

General 512MB memory, according to the actual use of memory footprint, you can set virtual memory for 256-768MB (memory + virtual memory and generally higher than the normal occupation of 256MB can).

1GB memory, according to the actual use of memory footprint, you can set virtual memory for 128-1024MB (memory + virtual memory and generally higher than the normal occupation of 256-512MB can). People who normally consume hundreds of MB (majority) can even disable virtual memory (with software restrictions that can set up a small amount of virtual memory, such as 16-128MB).

Memory is 2G and above, you can generally disable virtual memory (with software restrictions can set a small amount of virtual memory, such as 16-128MB). Some people who do use large amounts of memory, such as playing large 3D games, making big pictures, 3D modeling, and receiving low memory warnings, need to set virtual memory as appropriate.

Third: The larger the virtual memory the better.

Answer: wrong. The virtual memory is too large, which wastes the disk space, increases the time of the head positioning, and reduces the efficiency of the system execution. Correct settings to save 256mb-4g left and right space (depending on memory size)

Take the Win7 system as an example, the computer right key, properties, advanced system settings, Performance > Settings ..., Advanced, virtual memory > Changes ..., automatic management cancellation, custom size, settings, OK, exit reboot.

Memory is very important in the computer, all the programs running in the computer need to go through the memory to execute, if the execution of the program is very large or many, will lead to memory consumption exhausted. To this end, Windows uses virtual memory technology, that is, to take out a part of the hard disk space to act as memory use, which is called virtual memory, virtual inside the existence of a hard disk is Pagefile.sys this page file.
