Hey guys this is probably a no brainer but i wanted to check. I have an Asus P4P800 SE with 1gb giel deluxe dual channel pc3200 ram running in a pair 512x2. I want to upgrade with another 1gb but im not sure if i have to use dual channel for the other 2 slots or if i can just buy a cheaper pair of ram to stick in there? DO i need to buy pc3200 ram again/dual channel or can you mix and match dual channel with non dual channel ram? Thanks for any help in advance.
