Thanks to:

        Check speeds with psrinfo -v or /usr/platform/sun4u/sbin/prtdiag -v
Adrian Stovall <>
        Check OBP versions and part numbers of all boards
Matthew Stier <>
        Check 84MHz or 100MHz backplane
        Make sure all CPUs are the same and all boards have same MHz

All the CPUs are 400MHz -- we bought them all at the same time. It seems
that the I/O board is 84MHz, while the two CPU boards are 100MHz, so we're
going to try replacing that. Hopefully, we have a 100MHz backplane, which
the resellers tech guy seems to think we do.

Thanks much for all the info.
