New i7 930!

Question:
This processor has problems with multi 22X?

Yeah, for high overclocks, you should even odd multipliers, because i7 seems to hate even multipliers. This is true for any i7 chip though, not just the 930.

Anyway, I came across something _VERY_ interesting. Dropping my CPU PLL voltage from it's default 1.8v to 1.3 (huge undervolt) dropped temps on my CPU by a few degrees, and I now need LESS vCore to get my CPU stable at any given speed. Great little i7 trick! 4.2ghz is currently stable, but aiming for lower vCore now (using 1.344 at the moment).

this is nothing unusual, people used to do it all the time a few years ago, then once C2D came out it seemed like people stopped, i kept hearing that undervolting no longer helped.

What motherboard are you using?

I have an Asus P6T and i can't set it lower than 1.8v to test your theory.

I am about to try that trick and see what happens.
Currently @
CPU 1.325v
PLL 1.82
QPI 1.275
IOH v 1.14
ICH v 1.2
@ 4.2GHz testing.
I am going to drop the PLL to 1.3v.

Nope My board wont do PLL 1.3v that sucks. BIOS update ASUS pls
I was able to drop by .02v lol
