Hi Leeghoofd,

Unfortunately there is no way I can lower PLL and FSB term. voltage if I want to run stable at FSB444.
The only setting that I could lower was the DRAM voltage, and I need 2.02v.
Anything below that value will cause Prime Blend to fail.
I've tried changing memory timings like you suggested but it seems that I've hit a wall at FSB444 / RAM 1066MHz.

Now I'm running with the following settings, and still trying to lower FSB term. voltage.
Since I'm at 4GHz CPU clock, I don't know if I should try lowering CPU PLL with FSB400...

What do you think about this setup?
Thank again for your precious help.

Try the above settings plz... sure you need as much Vcore ? Try to lower PLL and FSB term voltage (if possible) Why don't you run 400FSB with 10 multi ? and ram at 1066 ( in case my settings wouldn't help ya to OC the ram... Gskills and Mushkins do 1081 daily with 450FSB) Also the board overvolts the ram so be carefull there you are going for 2.15Volts?
