I7 920 @ 3.8 Freezing

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.

  1. Your Vcore is too low bump it up a little try like 1.2 or 1.21 or somewhere around that should help.
  2. Still freezing, now at 31:26 of prime95. Temps never go above 69*c
  3. Is the QPI/VTT too high?
  4. Might be a little but you are getting longer just keep bumping up the Vcore and watching your temps.
  5. Alright, thanks.
  6. I have QPI.VTT @1.275 and Vcore @ 1.24 and still freezing. Any other suggestions?
    Temps are still never above 70*C
  7. 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
  8. I cant seem to get stable, any suggested voltages?

    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 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.
