Core i7/X58 Overclocking Thread

[ACS]

Ive got problems getting my board to even post at anything above 196bclk, 21x196 is prime stable for me with HT on @ 1.39vcc 1.35 qpi/pll .

When i put 197 no post , im sure i have more juice in this proc ;/ Tried anything i can think of , lowest mem/uncore/qpi dividers - bumped qpi voltage up to 1.55 , dram to 1.7 , vcc to 1.55. Laxed memory timings , tried skew settings - nothing. No post at 197 and up at all.

There was one time that PC posted at 197 noticably slower (watching the detect dram/cpu on the little lcd asus board has)and then froze on post. Cant reproduce this again thou, no post.

Tried 0903 and 0904 bioses, dunno if cpu just cant do above 196 or its a dummie board problem.

Any ideas ?
