Have you disabled Cool 'n Quiet ? I'm not sure how it works with Quad Cores but It may be disabling 2 cores to save power... Go into your BIOS And turn it off and see if that fixes it, If not your cpu may be half dead? Thats the only other thing i can think of.

Also, set your power plan to high performance. I'm just throwing ideas out there =| I'd be mad if I was in your situation.

I read on Tomshardware's review that Phenom compatible mobo's allowed you to turn off cores in the bios. Look for these settings.

Airdraft, make sure ACPI Multiprocessor PC is listed in the Device Manager under 'Computer'.

Let us know if it is there

Good luck

AMD Phenoms have a monolythic core. One core goes out, they all do. It can't be half dead.
