Well, I have tried the B6 bios but I have trouble with the multipliers. It seems to jump between 6 and 9 with my E6600.

I can not register at the Abit-forum because I do not get any verification image when I try to register. Does anyone here have the B6 R bios?

Also, I have problems getting higher FSB than ~430MHz no matter what multiplier I set. For you guys getting ~500MHz, at what FSB do you boot and can someone recommend voltages for that boot?
I have tried to boot with 440-470MHz with the same result: the loading bar when windows starts works but after that is finished the screen get black and the computer hangs. No automatic reboot. vcore set to 1.5->1.7 and vmch 1.3->1.7v. RAMs are good enough.
