I've just run cat /proc/cpuinfo on my HP Proliant ML115 (Quad Opteron) and the results are indicating that the cpu is only running at 1050 Mhz. Any ideas why?

My Q9550 correctly reports 3739.879 MHz as its cpu MHZ, which is my current clock speed.

Do AMD chips use a different speedstep type thing, or is it set-up wrong?
