Yet another reason to run the world renowned PC PItstop OverDrive Scan.
OverDrive features a Memory Load Test that measures the percentage of RAM currently in use on a system.
Use the information in your OverDrive test results to learn more about the RAM usage of the applications that are running on your PC and how to make your system run more efficiently.
The most common cause of a high memory load is running too many applications for the available RAM. If you run more applications than will fit in the available RAM, Windows will decrease the size of the disk cache and increase the amount of paged virtual memory coming from disk. RAM access is much faster than disk access, so when you overload RAM and the system uses disk space to compensate, the system slows down. This is sometimes called thrashing.
