There are more and more users using the Windows 7 operating system, so you know how to properly set the virtual memory of the Windows 7 system? Let's take a look at it with Xiaobian.
1, what is virtual memory?
Memory plays a decisive role in the computer, all running programs in the computer need to go through memory to execute. If the program being executed is too large or too large, it will result in exhaustion of memory. In order to solve this problem, Windows uses virtual memory technology, which takes out part of the hard disk space to act as memory. This part of the space is called virtual memory.
In fact, virtual memory is only a supplement to the lack of real memory, so don't deify it. The read and write performance of virtual memory is only a fraction of the real memory performance, and it is very harmful to the hard disk! Therefore, Xiao Bian suggested that everyone take "do not need to use it, can use less and use less! The principle is enough to use + leave a small amount of margins."
2, virtual memory optimization
generally can first disable virtual memory, restart the computer into safe mode (do not run a lot of programs at this time), and then defragmentation, reset virtual memory after completion, the page can be made The file is free of fragmentation and reads and writes faster.
3, virtual memory settings
take WIN7 as an example, computer right, properties, advanced system settings, performance > settings..., advanced, virtual memory > change..., automatic management cancel, Custom size, set, OK, exit reboot.
4, the misunderstanding of virtual memory settings
1 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)
2 virtual memory should not be set in system disk C disk (system disk is the same as other disks), but 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? 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.
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.
General 512MB memory, according to the actual use of memory, you can set the virtual memory to 256-768MB (memory + virtual memory and 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.
