If you are considering a memory upgrade, it is a good idea to find out how much memory your computer currently uses. If only a small faction of your RAM is currently used, then adding more memory may not increase system performance as much as you might hope. Windows Task Manager will give you the information you need by displaying both the percentage and amount of memory used.
Right-click an empty area of the Windows taskbar and select "Start Task Manager."
Click the "Performance" tab of Windows Task Manager.
Look for the graphical "Memory" box for the number displayed. This figure is the amount of memory you are currently using.
Look at the bottom edge of Windows Task Manager, where it says "Physical Memory." The figure is the percentage of installed RAM the system is currently using.
Tips & Warnings
- To get a better idea of the demands placed on your system, reproduce the most intensive processing session you anticipate having, such as running several programs, performing an antivirus scan and opening large files. Read your memory usage again to get memory used during such sessions.
