Virtual memory is hard drive space on your computer that the machine uses as though it were RAM. If your computer is running low on RAM, increasing the virtual memory available can help to keep you from continually running out of physical memory. Virtual memory is not as fast as physical memory and is not the same as adding more RAM. Windows XP allows you to set the size of the virtual memory manually.

Skill level:


  1. 1

    Open the Start menu and select "Control Panel." Double-click the "System" icon.

  2. 2

    Choose the "Advanced" tab. Under "Performance," click on the "Settings" button.

  3. 3

    Select the "Advanced" tab in the new window. Under "Virtual Memory," select the "Change" button.

  4. 4

    Click the drive of which you wish to increase the size of the virtual memory under the "Drive [Volume Label]" heading.

  5. 5

    Select the "Custom Size" button under "Paging file size for selected drive." Enter new initial and maximum sizes in megabytes.

  6. 6

    Choose "Set" to set the new virtual memory size.

  7. 7

    Click "OK."
