Hello. New poster here.

I've run my E6600 on P5B Deluxe with following settings:

9,0 x 378MHz = 3402MHz
VCore 1,40V (1,375V was enough though)
DDR 2,1V
PCIE settings at 100 and 33,33MHz
Corsair 800MHz DDR2 mem at 4-4-4-12

Stable under Orthos for some hours and I didn't bother testing any longer. In P180 case with two S-Flex 120mm fans @1000rpm and Tuniq Tower 120 @1500rpm. Reasonably quiet (no sound heard from under the table while music playing).

Measuring with Everest Ultimate I have cores temps ranging from 33C to 55C depending on load in 22C room temp.

I would like to push for 9,0 x 401MHz. Some say that 401MHz is easier than 400MHz because of some strap thing or something else which I didn't really get. I'm back home tomorrow and will try the higher voltage settings given in this thread for chipset.

Any tips how much VCore should be a good bet to start trying to achieve stable system at 9,0 x 401MHz? DDR should run without problem at it's specsed 2,1V at least to that 800MHz. The other voltages, I've understood, one can set pretty freely to the max values?
