shoot, i have 8370 @ 4.82 w/ 8GB dominator platinum 1866 running @ 2133 10-11-10-30-40 (NB @2200) and running gta V I get a decent boost running my ram @2133 vs 1866! it feels way smoother. but for some reason i can't get my NB even to 2300 w/out having problems. and i have had it in a asrock 990 ex4 and now in asus sabertooth 990 r2 and motherboard made no difference. so it must be my NB. but hey i'm happy w/ it. can game @ 5GHz w/ her but not prime stable. (at least in the summer).
PS. seen earlier in this thread about having NB and HT @ 2500?? well BD/PD's HT is 2600 stock. It should be run at no less. I think thats why a lot of early reviews didn't get as good of performance because everyone was clocking HT/NB @ 2000 like it was a phenom!!!
