I am getting a P5k Deluxe MOBO. I would really like to run 8gigs of ram with the way price are right now but of course win xp can only use 4gb. So here is the question. With DDR2 (i am guessing 800 or maybe 1066, not sure yet) am i going to get better performance with using 1gb x 4 sticks or 2gb x 2 sticks. It will be dual channel sets and I plan on overclocking. Also if you have any preferences to timings or brands or lantencies to match with this MOBO it would be greatly appreciated.
