Increasing Virtual Memory in Windows 7 or Page File size can help to speed up your computer. The term Virtual Memory implies the additional Virtual Random Access Memory or RAM that is available. The Virtual memory is accessible by programs when sufficient physical RAM that is available. The virtual memory is accessible by programs when sufficient physical RAM is not available, or when a program has been designed for using virtual memory in order to increase the efficiency level.
A Low virtual memory will result in errors, and when you trying to start an application, the display message, in this case, will be “Virtual memory is too low”. The Windows Virtual memory helps the computer to shift the data to an empty space (in a file called “Pagefile.sys”) on the hard drive when you have no physical RAM available. The computer is able to get the data back to RAM when needed.
Having enough available space in your computer ensures that your RAM and virtual memory will be functioning appropriately. By increasing virtual memory, you will be able to have enough free spaces to store data. By automatically freeing the resources in the Registry, you can increase Virtual memory performance.
How to increase Virtual Memory:
Follow the steps to Increase Virtual memory in Windows 7.
By default “Automatically manage paging file size for all drives” setting is selected so that windows Windows & can manage the paging file without user’s interruption. If you want to change the paging file size, move the pagefile.sys to another drive or disable virtual memory paging, uncheck the check box of Automatically manage paging file size for all drives.
Select the drive that has the paging file that you want to change under Drive. Click on the Custom size button and fill the memory size that you want to keep reserved for virtual memory by entering initial and the maximum size
Note: Make sure you choose the same amount of memory size for the initial size and the maximum size. This will help you to prevent your CPU from the constant variation of the paging file. It would be best to keep the memory value 1.5 times more than the physical RAM, For example: If you have 1024MB RAM, you will want your Virtual Memory set to 1536MB. This should help you to increase Virtual memory and enhance the performance of you Computer.
Then Click Set and on OK. The changes you just made probably require Restart, Click OK.
