It was the Opteron that had the speed issues. The Xeon  cpuinfo and bios
data matched.

These were "loaner" systems to test usability for a specific function.
They have been returned today. So I can't get the exact cpu id strings.
They all matched up OK for the Intel but they did NOT match up for the
Opteron. I sadly did not make a copy of the cpuinfo data due to time
constraints. I don't recall if the Opteron specifically stated that it
was a 285 model or not. Hmm. The BIOS did and the sticker on the cpu
cage did.

I am suspicious if the wrong cpu was installed or the motherboard was
misconfigured and the chip clocked down. No docs on the board.
