Alien Grey, i used to run the Q9650 on the RF @ 4.05GHz 1.35v, men @ 1128MHz 1.85v fully stable and that was on bios 0802.

if i were you i would jump ship and go for the i7 LGA 1156 CPU much better and easier to OC. ASUS has stopped supporting all the LGA 775 boards. Kinda sucks really but thats the facts. Since i changed i really happy with it.
