I am thinking of upgrading the ram in my laptop. it has 256k in it and i think that it is a pc2100 module that operates at 266 megahertz.
The computer has an empty slot, so i can add a module easily. My question is does the new ram have to be the same speed as the original? it is a 200 pin slot and this is in a hp ze4805 pavilion. It has xp home. would xp pro speed it up enough to be worth the expense?
