Right now I have 1 gig of pc 2700 ram, and my motherboard, ABIT's IP-95, supports up to PC2 4200. Never having over- or underclocked anything, I was wondering if I would be able to use some Corsair PC2-6400 RAM http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=85025-6&prodlist=dealnews underclocked on my board. I just want to make sure there is nothing I am overlooking, because as I said I have never done this before. MY reasoning for PC2-6400 is because it is cheaper, and I plan on possibly upgrading later on.
