for 3930k.
if you don't go on Liquid cooling, you are wasting your chip!!!!!

Clock Speed: 5.0 (for 24/7)
Multiplier: 50
BCLK / BStrap: 100
Manual Vcore: 1.5V
Cooling Used:
1, custom loop max on Prime95 for 12 hrs: 68.5'C
2, H100 with push/pull, on Prime95 for 12 hrs: 84'C

Air cooling will cause the chip to eventually throttle at 1.5V. Not ideal.


I have this chip for 4 months now, been abusing it day in and out, it is ONE TOUGH chip!!!!
I have tested as high as 1.6V on benching, and so far, no signs of degration whatsoever.
Further, I haven't have read 1 report of people seeing this chip degrade.. I am about to believe that the majority of the people are just whimps.
this chip can handle 1.5V on 24/7, No Problem.

While I wouldn't call people wimps, I do think this chip points more toward the older style CPU's as far as voltage use goes since the SB/IB chips seem to work on much lower voltages and seem to take less.

Either way I guess I will have to start from step one as my chip either really hates Offset, or some random setting is being missed/messed in the bios. No way am I getting the same OC's out of this thing so far with the low voltages shown here. 1.47 vcore (from a +.105 offset, medium LLC) and it still will 101.
