One core is still running seemingly without problems it is only one core 
I disabled not the entire cpu. APIC 1 and 2 I believe are on the same 
chip. I am not a super CPU design expert, but if the two cores are on 
the same cpu chip do they not share the same memory bus with this model 
of the AMD cpu?

Or you could just move around two cpu cards and se if the error jumps 
from apic 1+2(err) to apic 3+4(err). If these are issued in order by 
FreeBSD? Or is the ordering random?

I suppose I could move all of the boards one step to the right and test 
it that way regardless.

If it does it is probably a DIMM or, as you say, the memory bus if not 
it is probably the cpuboard slot on the mainboard itself.

I will try this and post my findings.

Offtopic:

I cannot belive how poor the onboard bios diagnostics are on this server 
compared to my old IBM netfinity 5000.
