Hi, I have a PC I built about a year ago and stuck 2 x 1 GB memory modules in it. I want to add more. But how do I know what the max is i can put in my PC is ?

and what kind of memory? etc etc? Do i have to take computer to bits to find out what make of mobo it is and cpu etc as I have forgot what I have brought, I know it is a dual core cpu though.

thanks

Thanks guys will do that later,

main thing is i am running 2 gb memory and my friend has started using my computer with cs3 and she is into photography and she shoots in RAW, just takes a while viewing raw files on my PC, wondered if that was just down to 2GB ram ? I am using Windows 7
