ok... have bought the 2x512 corsair ram... i got alot of condradictory reviews, but i dont really intend on going above 2gb RAM in this comp, so i figured id use the dual channel thing... CHEERS FOR ALL THE HELP GUYS!just as a final thought, would it be worth putting the existing ram stick (512) into bay 3, or would this slow down the ram as it is a different make of ram?
