First: Sorry for my bad English.

I have the same Problem like Jor3lBR with 2x2048MB RAM, DDR1066 and MCH-Voltage, he discibes on Page 58/59.

but it is more bad, my "Stuck" MCH -Core is 1,2V!!

Corsair Dominator 2x2048MB DDR 1066 5/5/5/15, the CPU is a Q9550 E0.

When i set everything to DEFAULT (FSB333x8,5, DDR1066) i can boot and everything is fine. Even DDR 1080 is no Problem.

But when i raise the MCH-Core Voltage over 1,2V the Board loop in Reboots. I must turn down FSB to 325 (DDR 1040), then i can boot.

I need higher MCH-Core Voltage then 1,2V for my Quad at higher FSB, but then i cant run DDR 1066or higher!
(For Example FSB 445 and 2.4B=1066 -> not possible over 1,2V MCH
FSB 433 and 2.4B=1040 -> possible with 1,2-1,4V)


What is the Problem, is the Board damaged or the RAM incompatible?

Any solution?
