ASUS Maximus II Formula - new P45 king?

[Codeman05]

Guys, need some help with an e8400 (my e8500 killed itself this weekend).
I can't even get this guy stable at 4.0GHz, and I'm pretty sure its not the CPU as I could get 3.8GHz w/ 1.325 volts and I also had hell getting this board over 450 with the e8500.

Prime Blend fails in less than 15 mins...or the O/S freezes up.
Temps as follows: Cpu= 56/57 | Power=41 | NB=46 | SB=42 | MB=37

Any suggestions?
