30: How Do I Change My Virtual Memory
Microsoft usually recommend that you allow Windows XP to manage your
virtual memory (also referred to as Paging
File.) However, sometimes you can get bombarded with
messages saying that you do not have enough
virtual memory and Windows needs to make necessary
adjustments to the virtual memory.
In order to get around this problem it sometimes
becomes necessary to manually adjust the virtual
memory. This can be done in the following way.
- Click the Start button.
- From the Start menu Click
- When the Control Panel window
opens click the System Icon.
- In the System Properties
window click the Advanced
- The top section of the Advanced
tab window is market Performance.
- Click the Settings button.
- The Performance Options window
- Click the Advanced tab.
- At the bottom of the window you will see a
section marked 'Virtual Memory'
Click the Change button.
- In the next window your main C:
drive should already be highlighted. If it
isn't then right click on it with your mouse to
- Now look just below the Drive section.
You will see a section marked 'Paging File
for selected drive.'
- Right click on the
radio button next to the Custom
size to enable this option.
- The Custom Size dialog box
now become available for use.
- The normal formula for virtual memory is
1.5 times that of your physical
memory. So if you have 128MB of
physical memory the formula would be as follows:
128 + 64 = 192MB (64MB being half of 128).
- In the Initial Size (MB)
dialog box type in 192MB (or whatever figure you
have calculated - in our example 192MB).
- In the Maximum Size (MB)
dialog box type the same figure, i.e., 192MB.
- Now click the Set button to
save your new settings.
- Next click OK.
- In the next screen click the Apply
button followed by OK.
- You should now be back at the System
Properties window. Click OK
