If you wanted to upgrade your RAM, how do you go about it? Would you just need another RAM of the same size (ie you have say, 256mb so you add another 256mb module) or do you need to have another of EXACTLY the same type (ie: same make, model, size etc) or could you add one made by a different manufacturer (ie, aftermarket one) as long as it is the same size as the one you have in your machine and if it is compatible with your machine....

Anyone help me?
