Thats strange, i got my memory secondhand, the person (a great bencher) ran them a few times with 2.6V. i only run at max 2.48, and they still perform. and run at stock. they are insane though, can do 1200 4-4-3-3 : 1180 4-4-2-2-1 . screenies to prove it

Ive been running only on Asus x38 and x48, i think their stability is keeping the mem as lively as possible. im with zsams
