Win7 virtual memory setting error and correct method

Virtual memory is a technology for computer system memory management. If the computer lacks the random access memory (RAM) required to run the program or operation, Windows uses virtual memory to compensate. Virtual memory combines the computer's RAM with the temporary space on the hard disk. When RAM is running slowly, virtual memory moves data from RAM into a space called a “paged file”. Moving data in and out of paging files frees up RAM to get the job done.

Virtual memory is just a supplement to the lack of real memory, so don't deify it. The read and write performance of virtual memory (that is, hard disk read and write) is only a fraction of the real memory performance, and it is very harmful to the hard disk. ! If you can use it, you can use it less! The principle is enough to use + to leave a small amount of allowance.

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

Answer: 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? Is the head positioning! The positioning of the head in the same partition is undoubtedly more time-saving than the long-distance positioning across the partition! Therefore, the virtual memory (system default) in the system disk is the fastest and most efficient.

The optimal value for 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.

The larger 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.

How much is the virtual memory setting of Win7?

The memory usage of Win7 is bigger than XP and the management mechanism is different, so you can't use XP era. The standard is to measure. Win7 has prioritized the use of physical memory. If there are not many web pages opened at one time, the usage like you can refer to the virtual memory setting of 300-1000MB, which is a dynamic value to cope with the temporary virtual memory usage.

win7 virtual memory settings if you want more stringent set the virtual memory size, virtual memory necessary to detect specific amount. You can roughly add a memory counter to the peak value of the computer management & rarr; performance & rarr; monitoring tools & performance data counters, and then set the virtual memory value according to this usage.
