ASUS Maximus II Formula - new P45 king?

[drnick]

Hey, I was wondering if I could get some advice on what to tweak to get a stable 4+ GHz with this board and an e8600- I've looked through the thread and tried setups posted by cstkl1, BuGjAE, radaja, CryptiK, and others that have posted 4+ GHz dual core bios settings, and with all of them orthos invariably craps out with a rounding error within minutes (no pattern in which core fails that i could detect.).

Specs: MIIF 1306 bios w/ e8600 VID 1.25 watercooled
GSkill 2x2gb pc8800
pcp&c 750w
winxp64

I can get pretty decent memory bandwidth with the following settings (and I ran memtest for 5 complete rounds and 30 rounds of test 5 without errors), but again it fails orthos within minutes (usually seconds):

Thanks for any suggestions. I was wondering if I just needed to bludgeon it with more vcore, or if it simply won't fly with this lofty of a fsb goal (but many of the other setups I've emulated employ a lower fsb in the upper 400's to lower 500's range, and I still can't get stability with them). I did set everything to stock timings and volts and i ran an error free orthos session for 8hrs (I was hoping this would throw errors too so i could blame the equipment!!!)

EDIT: I just got home to see my system at 4.05 GHz (450x9) is still priming error free at 10 hrs! I know I've tried 450x9 before and failed; I did however flash to the 1307 bios, disable loadline calibration, and bump up vcore a bit (I think I'm at 1.42 in bios and 1.36 according to everest under load) this time compared with previous failures at this speed.
