About the misunderstanding of setting virtual memory in Win7 system

In Win7 systems, when there is not enough memory, we can set virtual memory to replace physical memory usage, which can make the program think it has enough memory to run, but not. However, some users think that the larger the virtual memory, the better. Actually, it is not. Let's share some misunderstandings about setting up virtual memory in Win7 system.

System Settings on Win7 virtual memory errors

Myth: virtual memory the better

Answer: False! 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)

Myth 2: Virtual memory should not be set in system disk C (system disk) and should be set 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.

Myth #3: 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 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 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 above is about the misunderstanding of setting virtual memory in Win7 system. Through the above introduction, I believe that everyone has a certain understanding of virtual memory, I hope to solve the confusion for everyone, carefully use virtual memory.
