When talking in the simple words then the Virtual Memory is actually the system memory which is simulated by the operating system. It is placed in your hard drive. The purpose of this memory is to combine the RAM of your computer with the temporary space which is available in your disk. When your PC is running low on RAM then it is the duty of the virtual memory to move the data from the RAM to the space which is called the paging file or the swap file. With the help of this movement of data, your RAM would be freed and the applications would be able to run without any sort of crashes. If there is not too much of RAM installed in your system then it would be a great idea to increase the size of the virtual memory of the system. The configuration of virtual memory in Windows Vista operating system is quite easy and can be done by following certain steps.
Increasing virtual memory
In order to increase the virtual memory of your Windows Vista system, you should first click on the computer on desktop and then right click on the icon of computer and click on properties in the menu. In the windows of System, click on the Advanced Systems Settings. The properties of the Systems windows would open on the tab of Advanced. In the performance section of that tab click on the settings button and then in the performance options window you would come across the current size of the swap or the paging file. In order to configure it you should click on change.
In the default manner Windows Vista itself manages all of the paging files sizes for the drives. In order to change these settings you should first deselect the checkbox. You can easily customize the file size of paging for each of the drive that you have in your system. Bu default, the paging file is present on the C: drive and the system automatically manage it. If you wish to use some other partition then select C: and check the option of No Paging File and then click on the Set button.
Creating paging file on another partition
Now you would require creating the paging file for the Windows Vista on some other partition. Click on the partition which you would like and then select Custom size or the System managed size. If you wish to customized size paging file you would have to write the initials and the max size. In order to get the initial size you must have a few hundred megabytes and in order to type in the maximum size you should write almost 2.5 – 3 time of the size of your RAM. Some of the enthusiasts also recommend that one should use the fixed size paging file. If you wish to go for this option then the size must be 2.5 to 3 times of the RAM’s size. The performance of the applications running on your system would be affected if you have a small paging file especially if you are using such applications which need a lot of memory.
