If you looked at my sig, I have 2x2gb Gskill PI PC28800's. Hoss, also had 2x2gb OCZ 1066 RAM and had the same exact issue. Using less then 1.34MCH fixed our problem, bios F7/F8 and F9B, revision 1.1 board. We also both have Q9650's, so if your dual core chip causes it to not be able to boot over 1.26MCh then I am not sure what you can do, sorry

i don't think is the cpu, cause its a great one, i think it's the motherboard which is rev. 1.0 and that's why i guess i can go only as high as 1.26v on the 333 latch. Youre ram is better than mine and maybe they are more stable with less mch volts.
Anyway some problems still are with this motherboard , why making available mch volts up to 1.6+ when u can use a max of 1.34 or 1.26 in my case. There must be some issues causing this loops after passing a certain mch lvl .
