What I meant was that IC choice (CFR) on these 2400C11 is somewhat unexpected while quality (obvious binning rejects) is not.
Belial, may be it's your iMC that can't do 1300MHz stable, happens sometimes. Have you tried tightening them at 1200?
If you mean the PSC, the best they did on 5ghz Ivy:
Good Kit 2x2: 2400mhz 8-12-8-28 1.75v (tight secondary/tertiary)
Bad Kit 2x2: 2400mhz 8-13-8-29 1.8v (tight secondary/tertiary)
Good+Bad 4x2: 2200mhz 8-11-8-27 1.75v (tight secondary/tertiary)
I played a bit with 2600mhz CL9 on 2x2 on the good kit, i got errors and stuff, but I dont know if it was the imc or the ram. I assumed, at the time, it was the ram because changing vtt/imc voltage had no impact on stability (even reducing it didnt make it more unstable), and figured 2600 CL10 woudl be slower than 2400CL8, which isnt true but I assumed so at the time.
As for the hynix, I really didn't play much with them but no i didnt try playing with them at 2400, I'll see if they can beat 2400 CL8-12-8.Edited by Belial - 6/14/13 at 10:29pm
