Interesting. Are these the results of the turbostat program? What does
powertop show in the idle stats?

Yes, they should work at the native clocks. Don't even try mixing
different generations of Opteron even with the same socket, it won't
work, but a minor clock difference shouldn't be a problem in the same
overall family (e.g. mixing an 82xx with an 82yy should be OK).
