Do you know if the tyan BIOS has all the latest processor errata for
your CPU rev implemented?  We were working with 2 very large opteron
systems, one with B3 rev CPUs and another with C0 rev CPUs.  At the time
the BIOS didn't implement all the errata for the B3 rev of CPUs so they
crashed regularly with very odd oopses (random memory corruption)
while the C0 based systems were solid.  After the BIOS was fixed the B3s
worked just as well as the C0s.

Analyzing lots and lots of oopses :)
