Virtual memory allows the system to use hard disk space to store information normally stored in RAM. Windows XP manages virtual memory by using a paging file. You specify the minimum and maximum size of this file. If the size is different from the default in Windows XP, applications may return errors. However, some applications may require a non-default size for the paging file. Change the size only if other applications aren't adversely affected.

To set the paging file to the default size:

Note: You must be logged on as an administrator to change the size of the paging file.

  1. Quit all applications.
  2. Choose Start > Control Panel, and then double-click System.
  3. Click the Advanced tab, and then click Settings in the Performance area.
  4. Click the Advanced tab, and then click Change in the Virtual Memory area.
  5. From the Drive list, select a hard disk partition that has free space equal to at least three times the amount of the computer's installed RAM. To determine the amount of space available on a hard disk partition, click the drive letter; the amount of space available appears in the Paging File Size For Selected Drive area.

  6. Click Custom Size.
  7. In the Initial Size box, enter a value equal to one and a half times the amount of the computer's installed RAM.
  8. In the Maximum Size box, enter a value equal to twice the amount of the Initial Size value.
  9. Click Set, and then click OK to close the Virtual Memory dialog box.
  10. Click OK to the alert "The changes you have made require you to restart your computer..."
  11. Click OK to close the Performance Options dialog box, and then click OK to close the System Properties dialog box.
  12. Click Yes in the System Settings Change dialog box. Windows restarts.
