BCLK: 181
VCore 1.1875
QPI/VTT 1.295



If I run Prime95 I freeze at 16:38 every time. Max temp is 66*C is there something wrong with my settings or what else would cause this?

Hardware:
i7 920
gigabyte x58a-ud3r
coolmaster hyper212 plus
corsair 650w
ocz 1600 gold(6gb)
antec 900 case

Thanks in advance.

Definitely voltage too low. I did my 920 to 3.6 GHz at 1.21875 Vcore, 1.31875 QPI/VTT. 1.2125 1.3125 lasted 8 hours with Prime95 without any error. Anything lower than that freezes Prime95 so I decided that increase each voltage by a step to be sure and tested for 24 hours.

I think you should try 1.225 - 1.325 at least but will have to watch your temp.

I got 1 hour Prime95 with that at 3.8 GHz but two cores went into the...
I got 3.7 on my 920 at 1.125 vcore......at 3.8, raised vcore all the way to 1.4 w/ no luck.

Turned of HT and I got all the way to 4.2 GHz ....then started fiddling w/ half dozen other settings w/ HT on and finally got 4.4 Ghz w/ HT on.

Turbo, C!E, CPU TM Function, A20M, SpeedStep, CState was disabled, load line calaibration anabled, CPU diff amplitude was 800mv, Extreme OV was disabled, CPU and PCIE Spectrums disbaled

I got 1 hour Prime95 with that at 3.8 GHz but two cores went into the low 70's. I read one Intel article (confession: don't understand much of it) but it says at 130W, temp is about 67.9*C so 70 is too hot for my liking. That was why I stopped the test (no error) and brought it down to 3.6 GHz.
