What is Virtual Memory?

Virtual memory is simulated RAM. When you have used up all your RAM, your computer will shift data to an empty space on the hard drive. The computer swaps data to the hard disk and back to your RAM as needed. When you increase your virtual memory you are increasing the empty space that is reserved for your RAM overflow.

Also having enough available space is absolutely necessary for your virtual memory and RAM to function properly. You can increase Virtual Memory performance automatically by freeing up resources in your registry. You may want to use a Registry Cleaner. Click Here to learn more!

5.Under Drive [Volume Label], click the drive that contains the paging file that you want to change.
6.Under Paging file size for selected drive, click to Custom size check box. You can enter the amount of memory you would like to reserve for Virtual memory by entering the initial and maximum size.
7.Click Set
When you are prompted to restart the computer, click Yes.
Special Note: You should choose the same amount for the initial size and maximum size. This will Stop your CPU from constantly changing the paging file.

HOT TIP: To stop your CPU from constantly changing the paging file, set the initial and maximum size to the same value. For example, 500 and 500. The value should be at least 1.5 times more than your physical RAM. If your computer has 512MB of RAM increase the virtual memory paging file to 1.5*512= 768
