It's the only way AMD could reasonably do it. To require a different
motherboard for X1 (?) and X2 chips would have the mobo makers rioting!
That's what Intel did. Requiring a new i945/i955-based board for their
rushed dual-core CPUs. Only use the same socket but varied pin
definition. If you put the new CPU on an i915 board, it will shutdown
automatically to 'protect'. In contrast Athlon64 claimed to be
designed with dual-core capability in mind from the beginning.
It is worth noting that some motherboard manufactures did produce boards
that don't work with dual core opterons. In particular the Tyan K8SR
prior to rev-D doesn't work because they proview a couple too few watts
to the CPU sockets.

The Asus A8V-E series also does not work. Asus claims that it's a
limitation of the Via K8T890 chipset, which is highly unfortunate
since it's otherwise a good motherboard. Not sure whether to be
upset at Asus or Via here, but either way I guess both suck =-)
