Since ET vs BIOS MCHref is pretty confusing, what is yours set to in BIOS? At 400 MHz I've left MCHref at default 63% of VTT while increasing VTT to 1.3v. But at 500 MHz system would crash if I didn't lower the MCHref a step or two.

funny thing is i couldnt past 450fsb whatever voltage i set for MCH and VTT, but after update to F6, it perfectly stable for 535, tried 550 and 560 but no stability on windows, i guess my 8Gigs RAM limited my OC, will try to boot with two sticks next weekend and see if can get higher
I've had trouble with F6. It wouldn't boot at PL10, only on auto (and maybe on manual but much higher than 10, can't remember). It seemed as if it always tried to boot at too low PL, even if it was set on 10. Went back to F5.

That's one nice e7300 you got there. Wish mine was as capable. Is it IntelBurnTest stable also?

Can your system wake up from S3 with current settings?
