I'm having some trouble with my QPI voltage. I've tried setting it withing 1.25-1.27v, and I can't get it stable, and Prime crashes almost instantly at those voltages. What am I doing wrong? I can't see why it should be higher
My i7 920 runs at the same speed of yours but with a very low voltage i.e below 1.1V


6hrs prime without errors.


Now it's running at 1.024V idle and 1.03V on load.

You can try to increase your Vcore to make it more stable.
