I'm going to be buying some RAM for the system i'm builing, the motherboard is the Asus p4p800. I was looking to get some Corsair memory, from what i've read it seems to be the most stable and pretty fast. I was looking to get 512mb. I was wondering what you guys think a good stick of RAM is? I don't know if i'm going crazy hehe, but i think i remember reading something about these double data rate motherboards run better with 2 sticks of RAM as oposed to just one, maiking sure there is either 2 or 4 sticks of RAM in the system? Am i right hehe? Thanks.
