You require a dual socket motherboard to run 2 single core opterons, and
you do not require one to run a single dualcore opteron. That is I
believe what I said, although maybe I messed it up somehow.
With the dualcore chip you can use a cheaper board to get 2 cores
running, but you only get half the memory bandwidth of a two chip single
core system.

Exactly.
