How much memory can I add to my computer?

Q I am looking to upgrade my computer in various ways, including getting a larger monitor and hard disk, but I’m particularly keen to add more memory. My computer is only a couple of years old, but I’m starting to notice that it is feeling the strain of some programs.

I have 2GB of memory installed and I want to know how much I can add. I know that there is a limit depending on the motherboard you have but after looking at mine, I am none the wiser. Is there an easy way to find out which type of memory I should buy to ensure compatibility as well as determining the maximum my motherboard supports?

A If you do not have the manual for the motherboard, you could find out what model you have and then look online for the specifications and limitations. However, you’ll probably find that it is easier to use a free online tool such as Crucial’s System Scanner. Visit the Crucial site, click the System Scanner link followed by the Scan My Computer button and you’ll be prompted to download the tool that will than scan and analyse your computer before providing you with a report.

This utility will analyse your computer and let you know precisely what type of memory you should be buying, what the maximum supported amount of memory for your motherboard is and whether the Ram has to be bought and installed in a special way – such as matching pairs.
