I hate to necro a perfectly dead thread, but I searched through 15 pages of AMD-related posts and did not see this come up again.
I am having the exact same issue, same motherboard, though with a different CPU. I just upgraded to a 960T, so I have to use the most recent, F6h BIOS (as far as I know). The symptom of this is that Windows Vista 32 can't seem to properly manage the p-states, and so the CPU spends most of its time screaming away at 3000MHz, when it should be happily idling at 800MHz.
The old chip was a 9150e, and it spent most of its time at 900MHz, so this one should be capable of this as well, given my usual workload (email, Firefox, Winamp). I disabled Turbo Core, and that seems to have helped, but it still runs too high. I will resort to K10STAT if I must, but I would really rather not have to mess with that.
The BIOS flash procedure went without a hitch and checksum was fine. Any ideas?
I have put in a ticket to Gigabyte tech support, but nothing yet.
