Well, since I'm running XP I got the 3gb kit from Crucial. It is sold as a 3 pack so its not like I'm just getting 3 separate 1 gb sticks. We'll see how it does.
i know its a 3-pack, and i understand, i was just thinking that running 1gb on one channel and 2 on the other might affect your ability to run dual channel, although ddr3's insane bandwidth might make up for the loss to some degree. It would be a shame if you had to end up running only 2gb
