RAM (random access memory) is a type of storage device that holds data on a temporary or volatile basis. A computer uses RAM for short-term storage. Testing the RAM of your PC will allow you to know how much space is available on your personal computer. Whether you need to upgrade your PC's memory or have a bad memory module, finding the amount of RAM on your computer is a very easy process.

Step 1

Left-click on the Start menu and click on "All Programs".

Step 2

Locate and double-click on the "Accessories" folder. Under the "Accessories" folder, double-click on the "System Tools" folder.

Step 3

Click on the "System Information" program to open up your system summary. You will see the basic information about your computer.

Scroll down until you see "Installed Physical Memory". The system summary screen will also show you the "total physical memory" and the "available physical memory" on your PC.


  • Refer to your motherboard's manual if you are planning to increase your PC's memory.
