How to increase virtual memory in Windows XP

Presentation
As its name suggests, virtual memory is physical memory.
Windows uses virtual memory when you do not have enough memory "normal" physical ability to accomplish a task. When you do this, Windows uses the hard drive to store information that is usually placed in the memory or RAM.
Virtual memory is simulated RAM. Once you have exhausted all physical memory, the computer will pass data to a blank space on the hard disk. Swaps data from the hard drive of the computer and back to RAM if necessary. If you do not have much space on the hard drive on the left and you have a lot of problems, lack of virtual memory may be the reason. When Windows runs out of memory (virtual and non virtual) just does not work well.
Why bother to add more RAM to your computer when you can use hard drive space instead? Main reason - RAM is much faster. Whenever you use a lot of virtual memory, your computer is down. The best solution is to get more physical memory. The minimum requirements for an operating system Windows XP is 512 MB and 1 GB minimum for Vista. RAM prices have been reduced today with a 1GB or 2GB for your team is not that expensive yet. The more physical memory is faster processing of your computer and will be able to run multiple programs simultaneously.
How to increase virtual memory
If you are low on virtual memory, or continue to receive messages indicating that you are, you can change the default "System managed size" or "No paging file" to "Custom size" to increase your virtual memory to an acceptable level for the configuration of your host computer.
In Windows XP
1.Click the Start menu and right click on My Computer and select Properties.
2.Select the Advanced tab and select "Settings" option of return.
3.Under Performance Options window, select the "Advanced" tab and click on "Edit" in the Virtual Memory section at the bottom of the window.
4.Under virtual memory, select "Custom size" on the file size for selected drive to manually configure the memory of the virtual machine.
5.Enter the amount of virtual memory you need to put in "Initial Size" and "Maximum size". You must choose the same amount for the initial size and maximum size. This will prevent the CPU from constantly changing the paging file.
Tip: To prevent the CPU from constantly changing the paging file, set the initial and maximum size with the same value. That is, the initial size of 768 MB and 768 as the maximum size. The value must be at least 1.5 times physical RAM. For example, if your computer has 512 MB of RAM, virtual memory increase of 1.5 * 512 = 768.
6.Click Set.
When prompted to restart your computer, click Yes.
In Windows Vista
1.Click the Start menu and right click on My Computer and select Properties, then click the Advanced system settings.
2.If the system properties, select the "Advanced" tab and click on "Settings" in the Performance section.
3.Under Performance Options window, select the "Advanced" tab and click on "Edit" in the Virtual Memory section at the bottom of the window.
Note: By default, Windows Vista is set to "Automatically manage paging file size for all drives." Disable this option and select Custom Size to manually configure the virtual memory on disk C.
4.Under virtual memory, select "Custom size" on the file size for selected drive to manually configure the memory of the virtual machine.
5.Enter the amount of virtual memory you need to put in "Initial Size" and "Maximum size". You must choose the same amount for the initial size and maximum size. This will prevent the CPU from constantly changing the paging file.
Tip: To prevent the CPU from constantly changing the paging file, set the initial and maximum size with the same value. It, 1500 MB 1500 MB initial size and also the maximum size. The value must be at least 1.5 times physical RAM. For example, if your computer has 1 GB of RAM, virtual memory increase of 1.5 * 1000 = 1500.
6.Click Set.
When prompted to restart your computer, click Yes.
Tips & Warnings
Play with a gradual increase until you are satisfied with the performance of the system.
Do not give virtual memory settings below the minimum allowed. This could cause system crashes and slow.
Check "Recommended" virtual memory settings "total size of the paging file for all drives" at the bottom of the window.
