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. 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. The virtual memory exists on the hard disk in the form of PAGEFILE.SYS.
virtual memory only supplement the lack of real memory, so do not be deified, one of only a few very real memory performance read and write performance of virtual memory (ie hard disk read and write), but also a large hard disk injury 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.
One: Virtual Memory should not be located in the system tray C drive (system disk to another disk the same way), but should be located in other non-system partition.
Win7 set the virtual memory to quickly boost its read and write speeds
Answer: False because the C drive as the default system disk, hard disk read and write is the most frequent 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 the virtual memory is the memory capacity of 1.5-3 times.
Answer: False want to be judged based on actual usage!. Especially the popularity of large memory today. Memory usage See the task manager's memory column.
general 512MB of memory, according to the actual use of memory footprint, you can set virtual memory to 256-768MB (RAM + virtual memory of, and generally higher than normal occupancy can be 256MB).
1GB memory, according to the actual memory usage may be set virtual memory 128-1024MB (memory + virtual memory and generally higher than normal occupancy can be 256-512MB). 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).
2G of memory and above, generally can disable virtual memory (with software limits can be set up 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: 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. Set up correctly can save about 256MB-4G space (depending on memory size)
