I had a similar issue and it took a motherboard replacement to get it 
fixed.  The CPU speed at bootup was all over the place, which was tied 
into the BIOS saying that the FSB was wrong (it also varied from boot to 
boot).  TAC had me upgrade the BIOS, then downgrade the BIOS and it 
still wasn't consistent.  (And this was even before getting into the 
application - it was during POST that the BIOS was reporting a 6Ghz CPU.)
