sorry guys, Forgot to add that i have 64 bit windows7 and thats why i wasnt sure if i could upgrade my 3GB to 4GB. Against my specs, i wanted to know if there was to be any conflicts with compatibility before i made the purchase
No, there won't be any compatibility problems whatsoever. The only thing that'll be affected is your wallet ;-)
I'm guessing you already have 1x 2Gb module installed, so you'll need another 2Gb module to get it up to 4Gb. If yes, then 2Gb starts at £18 click here (no stock atm) / click here / click here / click here. G
4 Gig ok for 64 bit. Download and run the Win 7 Upgrade advisor to check hard and software with 64 bit. You may have to download 64 bit drivers for some items.If everything is working now with 64bit, the extra RAM will improve speed and cannot be a conflict with anything.
Crossbow7, something you said made me realise something. I have 3GB installed but does that mean I have 2GB and 1GB running at the moment? So that means all I have to do is just buy another 2GB stick? Here I was thinking I had to buy 4GB (2x2GB) straight! Another thing to point out, I have no idea what brand my 3GB ram is? does it matter if its different, as long as it fits inside?
