We all know that memory is an essential part of the computer, all programs need to go through memory. If we open a lot of tasks at the same time, it will take up a lot of memory, and we can't run the extra program directly. Is there any good way to solve this problem? In WINDOWS, the technology of setting virtual memory is to take some of the hard disk out as memory. Below we will briefly introduce the methods and precautions for setting up virtual memory for the latest WINDOWS7 system.
First of all, we must first understand some of the misunderstandings of virtual memory settings. Some people think that the bigger the virtual memory setting, the better. This idea is completely 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 settings save about 512MB-2G of space. 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. There is also a very important point, the problem of which disk is set in the virtual memory, most people will certainly not set in the C drive, because the general C drive is the system disk, everyone will have this idea. However, this idea is completely wrong. Because the C drive is the default system disk, the hard disk read and write most frequently is the system file and page file. What is the most time-consuming operation of hard disk reading and writing? It is the head positioning! The head positioning in the same partition is undoubtedly more time-saving than the long-distance positioning across the partition! So, the virtual memory in the system disk (system default Value) is the fastest and most efficient implementation.
Then, through the above preparation and understanding is how to set up, WIN7 setting method is also very simple and convenient, through the following steps can be easily set. Computer Right, Properties, Advanced System Settings, Performance > Settings..., Advanced, Virtual Memory > Change..., Automatic Management Cancel, Custom Size, Settings, OK, Exit Restart.

Finally, after we set up the virtual memory, we must optimize it. Generally, you can disable the virtual memory first, restart the computer into safe mode (do not run a large number of programs at this time), and then defragment, reset the virtual memory after the completion, so that the page file does not contain fragments, and the reading and writing is faster.
