Virtual Memory is one of the vital factor for your system's performance.In this article I am going to tell you how to increase your virtual memory size which can result in increasing performance.

How to increase Virtual Memory size

If your computer is slower then one of the most vital causes is the installed RAM. If your RAM size is small and you are running more applications at a time, then you may face different problems.

To avoid such problems windows create a virtual memory space on your HDD and it automatically manages it. Virtual memory is nothing but the reserved memory space in your HDD to assist RAM. By increasing the virtual memory available for your system you can increase the performance of your system. Please follow the simple steps below to increase your system's performance.

NOTE:-Low RAM size is not the only problem for slower performance. The performance of your system also depend upon your processor speed and other factors. So by increasing only the virtual memory you may not experience more performance speed. Increasing the virtual memory will increase your performance a bit.

In the above picture you can find that C drive is selected and the option "System managed Size" is active. If "No Paging File" option is selected then we are not using paging file in that particular drive.

N.B:- The page file is created during the Windows installation and resides on the hard drive in which windows is installed. Page files are measured in MB and otherwise known as virtual memory and the size of the page file is based on how much RAM is installed in the computer. By default, a page file is 1.5 times the amount of installed RAM.

Step 4:- Change the Virtual Memory.

To set the virtual memory select the desired drive and see the recommended size and currently allocated size. Then select "Custom size" option.
Now give a "Initial Size" and "Maximum Size" in MB and click on "Set" to set the virtual memory.

Set Virtual Memory

You have to set the maximum size larger than the currently allocated size to increase the performance. For initial size it may be between the size of the installed RAM to currently allocated size.

NOTE:- While setting virtual memory make sure to close all the running programs. It is not mandatory to close all the programs but it is recommended.

You must have administrative access to the system to change virtual memory size.
