Was contemplating 4gb kit of ocz sli edition ram @ $90. got 2 of these at fry's for $49.99 - $30mir = $19.99 each. so $40 bucks for 4gb after mir. Not bad for D9FTB. So far 450 is not stable; 400 is though. got 4-2-2-6 2t @ 2.2v (it doesn't like CAS 3). Going to go lower latencies, and see if it's stable at all. still lookin for a 680i to play with. hopefully i can oc better with that.
