@David09 - Virtual memory is a swap file on your hard disk. When you’re RAM memory runs low, Windows uses the swap file. Data in the file is stored in segments called “pages,” which are basically portions of data clusters.
You can increase your page size by going into Control Panel, Performance and Maintenance, System, Advanced tab. Click Performance and Settings and then click the Change button under virtual memory. Click Paging file size and set a new size for the page. You are basically telling it how big of a chunk you want the RAM to swap out for memory. As a general rule you want to set your page size to 1.5 times the amount of RAM you have in your computer.
