first i have to make my windows bootup again, wrecked it by ram oc..

Ouch

And another update! Getting more excited now.

Though my only stability testing atm is a few hours of Prime long FFT's, Ill use some other applications later on as well. Is the AOD stability test worth anything or just like Prime small FFT, aka crap?

KTE tried the auto tune feature a week ago. That brought him above 3GHz but it was not stable. I assume that process uses AOD stability test functions, so they are not usefull.

I just quit a Prime which ALMOST ran 6hours at 1.3125Vcore and Vnb. With ~20C ambient (Im guessing), it only became 42~43C. I also just noticed, it runs (thus far) stable at only +0.0125V from default.

Do you use watercooling, you have no info about that in your sig?
If those overvolts i measured are correct and common to all boards your real vcore is at ~1.355V.

Thinking quickly what Ill test now, as Im going to bed in a few minutes. Thinking to drop Vcore and Vnb at a little below 1.3V and see how it does that.

With NB speeds below 2200GHz and NB voltages at ~1.3V i see no need to keep vcore and vnb in sync. Is there a bios manual from DFI available? Only have the sapphire descriptions.

I also thought, now Im searching for lower Volts, I must be burning the CPU nicely in now.

On the other hand that will shorten the lifetime of the cpu without doing something productive.
