I don't know that any of the 300MHz-capable boards *can't* do 400MHz.
IIRC, only the really old 501-2487 motherboard was limited to 200MHz
(there's no frequency select jumper between CPU0 and the SBus
connectors at all), and any rev of 501-3132 should be able to do 300MHz
What might not be immediately clear from the silkscreening for the
jumpers (again, IIRC... haven't been wrist-deep in a U2 in a few years)
is that you need to jumper the box as if it were a 200MHz CPU for the
400MHz to work. This is due to the required bus speed multipliers for
Hope that helps...
