Win7 virtual memory setting tips

As we all know, compared to the previous WinXP, Vista and Win7 have a larger memory footprint. Maybe 2G memory is enough for an XP computer, but it is just normal for Win7. Virtual memory is only a supplement to the real lack of memory, so don't deify it, virtual memory read and write performance (ie hard disk read and write) only 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 It should not be set on the system disk C (the system disk is the same as other disks), but should be located in other non-system partitions.

Setting Win7 virtual memory Quickly improving its read/write speed

Answer: Wrong! Because C drive is the default system disk, the most frequently read and write files are 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 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.

Third: 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 about 256MB-4G space (depending on memory size)

Take Windows7 as an example, computer right click, properties, advanced system settings, performance > settings..., advanced, virtual memory > change. .., automatic management cancel, custom size, set, OK, exit restart.

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.
