You can manually configure virtual memory by completing the following steps:
1. In the Control Panel, click the System and Security category heading link.
2. Click System. In the left pane under See Also, click Performance Information and Tools.
3. Under Tasks, click “Adjust visual effects.” This opens the Performance Options dialog box.
4. On the Advanced tab, click Change to display the Virtual Memory dialog box shown in below screenshot. The following information is provided:
Drive [Volume Label] and Paging File Size (MB)
Show the current configuration of virtual memory. The dialog box lists each volume with its associated paging file (if any). The paging file range shows the initial and maximum size values of the related paging file.
Paging file size for each drive
Provides information on the currently selected drive and enables you to set its paging file size. “Space available” indicates how much space is available on the drive.
Total paging file size for all drives
Provides a recommended size for virtual RAM on the system and shows the amount currently allocated.
5. By default, Windows 7 manages the paging file size for all drives. If you want to configure virtual memory manually, clear the “Automatically manage paging file size for all drives” checkbox.
6. In the Drive listbox, select the disk volume you want to work with.
7. Select “Custom size” and then enter an initial size and a maximum size.
8. Click Set to save the changes.
9. Repeat steps 6–8 for each disk volume you want to configure.
10. Click OK. If prompted to overwrite an existing pagefile.sys file, click Yes.
11. If you updated the settings for a paging file that is currently in use, you’ll see a prompt explaining that you need to restart the system for the changes to take effect. Click OK.
12. Click OK twice to close the open dialog boxes. You’ll see a prompt asking if you want to restart the system. Click Restart.
