I have tested bios 0507, 0512 and 0601.
0601 improved stability in a sense because now I can boot linked and synched at fsb 1800, 1850, 1900 (did not try above).

What is giving me trouble is the P1/P2 option.
As soon as they are enabled, I can't post anymore.
I have tested 2 different PC14400 kits (corsair dominator and cellshock), even with relaxed timings, still no post: stuck on "DET RAM"

The only way to finally POST was to set NB at 1.7V ! Anything below that won't make my board start...
What the hell?! I see all people using values of 1.44V, 146V max for NB with P1/P2 enabled and give very nice memory read in everest.

What is wrong with my s2e?
I easily go to 60°C when NB @1.7V :-(

- Do you guys care to share exp. about NB voltage?
- Why is everest read so bad with P1/P2 on auto?
