How to set win7 virtual memory?

There are two pieces of memory in the computer, one is physical memory, and the other is virtual memory. When the physical memory is not enough to support the computer, the computer will open up another path and support a computer to run. Disk space is called virtual memory! Let's teach you how to set up win7 virtual memory?
First understand the size of virtual memory settings
1. General situation
Generally, it is recommended Let Windows automatically allocate management virtual memory, which can dynamically adjust the size of virtual memory according to the actual memory usage.
2. About the minimum
Windows recommended page file minimum value should be the current system physical memory capacity plus 12MB, and for users with physical memory capacity less than 256MB, it is recommended to set the minimum value of the page file Larger:
1 For users who use 128MB or less of memory, it is recommended to set 1.75 times the current physical memory capacity to the minimum value of the page file.
2 For users with a memory size between 128MB and 256MB, it is recommended to set 1.5 times the current physical memory capacity as the minimum value of the page file.
3. About the maximum
In general, the maximum value of the page file is set as large as possible, it is recommended to set it to 2 to 3 times the minimum value.
4. Extreme situation
If the hard disk space is relatively tight, when setting the page file, just ensure that it is not less than 3/4 of the physical memory.
If the physical memory is large (greater than 2G), you can disable the virtual memory, which will make your computer run more smoothly.
