EP45-UD3P Benches 3D at 670mhz+ FSB

[Alcibiades]

Been trying all day to get around 500FSB stable on my Q9650. F4 and F5A bios.

Ive set vtt/Mch higher than i would normally dare but it didnt make any difference. Ive also copied Hicookies settings in this post but it still fails super_pi and blend instantly. My ram is OCZ flex 2 9200 so normally handles 500Mhz with ease.

Try dropping your MCH Reference volts from 0.760 -> 0.660 in ET6
Actually, just drop it one notch at a time until you are stable.
I set up ocz flex 9200's and flex 9600's on EP45-Extreme using 0.660v MCH Ref 1200Mhz DDR2 @ 2.1V

BTW can you pass memtest 5 and 7?

Also might wanna try 800-900mv and 200-300ps skews for cpu and MCH clocks
