Proof or it didn't happen.

Thanks all. I have vcore at 1.55 and cpu-nb at 1.54, CPU speed is 3.93Ghz and NB is at 2700Mhz, stress testing with IBT currently. Good thing I have it under water, it's hanging around 55, peaking at 58.

Try your CPU/NB volts at 1.35 to 1.40,You don't need it at 1.54 for 2700MHz.
Mine is at 1.40 for 2808MHz

Doesn't boot at all when I go that low. I have to reset the CMOS.

Wow really?Ok.

Edit:Keep your eye on the NB temps.

Turns out it is stable with 1.4 @ 2640 rather than 2700... oh well, I'll keep the voltage at 1.4, not worth the extra heat. Plus I have my CPU at 3.84 rather than 3.93, at 1.5 rather than 1.55.

too high...bring down your cpu-nb. for 2700...you might only need 1.3 to 1.35. your rams might not be stable or somthing. make sure your rams are stable first before you mess with the cpu-nb overclock. NM...thought you had the x6...its normal for the denab. max cpu-nb for the denab is around 2600 to 2800...anything above that is quite hard.
