I am running a Supermicro P6DNF (hope to add another processor
when the single-processor work dies down, to assist in the SMP

To the best of my knowledge (verifications performed on P6DNF)

Note that the bios startup screen does not always report the correct speed,
you'll need verify the speed by running some test program that is purely
CPU Clock dependent.
