Hi,
stupid question : isn't it possible that your motherboard does some sort of
overclocking when it detects high cpu usage (bus activity, etc...) ? It
should not be easy to check (rdtsc every second ?), but you might want to
explore such a possibility.

Hi,
I'm having a strange problem when I benchmark some of my physics
simulation code on my new Athlon 64 X2 4800 machine. It occurs on all
current kernels that I have tested including 2.6.12.5 and 2.6.13.
If I run my benchmark single threaded, so that one of the two CPU cores is
just idling
