How to set Win7 virtual memory best

At present, the most popular Win7 has a much larger memory footprint than the previous XP system. Maybe 2G memory is enough for an XP computer, but it is just normal for Win7. Virtual memory is only a supplement to real memory shortage, so don't deify it. Virtual memory read and write performance (ie hard disk read and write) only has real memory performance. A few tenths of a degree, and the damage to the hard disk is very big! If you can use it, you can use it less. If you can use it less, you can use it less! The principle is enough to use + a small amount of allowance. To this end, the importance of virtual memory is self-evident, so today we will lead everyone to understand the Win7 virtual memory setting skills. For the general case, we recommend the following method:

One: virtual memory Should not be set in the system disk C disk (system disk is the same as other disks), but should be set in other non-system partitions

Answer: Wrong! Because C disk as the default system disk, hard disk read and write most Frequently, system files and page files. 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.

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

Answer: Wrong! It should be judged according to actual usage. 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)

Win7 system as an example, computer right button, properties, advanced system settings, performance > settings, advanced, virtual memory > change, automatic management Cancel, customize size, set, OK, exit reboot.

The memory plays a big role in the computer. All running programs in the computer need to be executed through memory. If the program is large or many, the memory consumption will be exhausted. To this end, WINDOWS uses virtual memory technology, that is, take out a part of the hard disk space to serve as memory. This part of the space is called virtual memory, and the virtual memory exists on the hard disk in the form of PAGEFILE.SYS.
