Probably way off topic, but just wondering how you can tell if you have say 2x512mg RAM sticks or just 1gig of RAM stick. If I do ever upgrade my pc (I'm going to wait to see how it handles m2tw, if its struggling I'll upgrade), I can only afford to upgrade ram (I currently have a gig, il upgrade to 1 and a half gig). So I'm a total novice at these sorts of things and it'll be a job of giving my pc to a local pc shop, and telling them what to upgrade, but if I have 2x512mg then I'll have to add a stick of a gig right? (assuming theres only two "slots", which i guess there is, again im a total novice with hardware) but if I have just 1x1024 then I'll only need to add a stick of 512mg which is obviously cheaper, but it'll have the same effect. (so I'm hoping iv just got 1 stick of a gig). I have no idea if those "calculations" lol there mroe like complete guesses, are correct, please correct me!

But ye, how do I tell, without taking my pc apart, if I have 2x512 or 1x1024
