What is Virtual Memory?
Virtual memory combines your computer’s RAM with temporary space on your hard disk. When RAM runs low, virtual memory moves data from RAM to a space called a paging file. Moving data to and from the paging file frees up RAM to complete its work.
The more RAM your computer has, the faster your programs will generally run. If a lack of RAM is slowing your computer, you might be tempted to increase virtual memory to compensate. However, your computer can read data from RAM much more quickly than from a hard disk, so adding RAM is a better solution.
If your computer lacks the random access memory (RAM) needed to run a program or operation, Windows uses virtual memory to compensate.
Virtual memory and error messages
If you receive error messages that warn of low virtual memory, you need to either add more RAM or increase the size of your paging file so that you can run the programs on your computer. Windows usually manages the size automatically, but you can manually change the size of virtual memory if the default size is not enough for your needs.
Change the size of virtual memory
If you receive warnings that your virtual memory is low, you'll need to increase the minimum size of your paging file. Windows sets the initial minimum size of the paging file at the amount of random access memory (RAM) installed on your computer plus 300 megabytes (MB), and the maximum size at 3 times the amount of RAM installed on your computer. If you see warnings at these recommended levels, then increase the minimum and maximum sizes.
To optimize the virtul memory follow these steps:
1. Open System by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking System.
2. In the left pane, click Advanced system settings. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
3. On the Advanced tab, under Performance, click Settings.
4. Click the Advanced tab, and then, under Virtual memory, click Change.
5. Clear the Automatically manage paging file size for all drives check box.
6. Under Drive [Volume Label], click the drive that contains the paging file you want to change.
7. Click Custom size, type a new size in megabytes in the Initial size (MB) or Maximum size (MB) box, click Set, and then click OK.
8. Increases in size usually don't require a restart, but if you decrease the size, you'll need to restart your computer for the changes to take effect. We recommend that you don't disable or delete the paging file.
