From my experience if your CPU is unstable at a certain frequency under x64 OS try to LOWER vCPU. It worked for me, but you can't gain to much out of this solution. Much better cooling might help as well.
A lot depends on BIOS support. Gigabyte DQ-6 is a good example. None of my Phenoms could go stable beyond certain frequency and my 9850 for instance would be unstable at around 2700MHz (5 min. stable @2760MHz) on BIOSes up to F4. With new F5c BIOS I can get it absolutely stable @2760MHz default vCore!

@xPliziT Very good point! I was thinking the same! Only future revisions can change this situation.

Good luck guys in yours x64 adventures!!
This is good to know, I hope it's true for the DQ6. I'm about ready to reawaken my DQ5.

Are you on X86 or X64?
