I'm performing a few upgrades on my cousin's rig here. I've noticed something odd about his cpu clock frequency.
First of all, the mobo is an Asus A8R-MVP running an Athlon X2 3800 overclocked to 2.4GHz.
Before, the CPU ran at a constant 2.4GHz. Yesterday, I flashed the BIOS and now it'll sometimes run at 2.25GHz. It's 50/50, really; sometimes it runs at 2.4, other times at 2.25.
Cool'n'Quiet is DISABLED! I'm seeing nothing else in the BIOS that would throttle the clockspeed. The temperature is a cool 38 C.
What's wrong with this thing? Thanks for any help.

He plans to install an Opteron 180 chip, which, according to Asus, requires a more recent BIOS than the one he was currently running. That's why I flashed it.
Any clue on why it sometimes runs at 2.25GHz now?

Asus was of no help. :(
All right, I discovered today that the behaviour is not random. When I cold boot it, it only runs at 2.25GHz (225x10), but if I restart it from Windows, then it'll go up to 2.4GHz (240x10).
Why is this???
