ASUS Maximus II Formula - new P45 king?

[Grnfinger]

Hey guys I need your help. I was Prime95 "Blend" stable 2 hours with bios 701 and I flashed up to 1307 and it craps out in a matter of minutes now. Here are my settings, please look them over and make some suggestions. I am not trying to hit real high numbers just 3.7 for my daily machine. This chip is a "C0" revision and not the best clocker by any means. This is the machine in my sig.
Thanks.

going back to 701 is your rig stable again with same settings.

Why are you running PLL so high? I doubt it need to be set so high, I'm running 1.5 ( bios ) for 3.9GHz 459x8.5
