I tested my CPU today on an ASUS Sabertooth P67 board, and it only produced more heat... I got the idle voltage lower than on the UD3, by using some more sophisticated LLC option. I guess the more expensive boards have more LLC options. Using the first options (regular and medium) gave approx the same results as on the UD3.

However, the load voltage had to be 0.005 or 0.010 higher than at the UD3, which produced 5-10 degrees Celsius more heat. (Using a Cooler Master v8, for those interested). The temp went from max 65C on UD3 to 70+C on the sabertooth.

The sabertooth is going back; guess not all 2600k's are equally OC'able, so i'll have to do with my 4.5GHz @ 1.35 idle, and 1.27 on load. Never been so happy with the UD3.

Needless to say, I am quite saddened by this. I suspect more and more it might be the board, as I've tried many different bios to no avail, but am really unsure. Any ideas? Any and all help would be appreciated!

Buy an ASUS board. Everyone with an ASUS board can get to 5 if they want to.

I wasn't, at least not under acceptable temperature running prime.

PS> Lowering PLL to 1.74 might help getting it stable
