Hrm.  IIRC all the BIOS parameters are default (I could be mistaken).  
It's a
SuperMicro X8DTN+ motherboard with:
CPU: Intel(R) Xeon(R) CPU           E5645  @ 2.40GHz (2400.22-MHz 
K8-class CPU)

   TSC: P-state invariant, performance statistics

avail memory = 75186962432 (71703 MB)
(2 packages, 6 core, 12-threads each) and 18 4GB sticks.
this ONE slot seems to be a problem.

How would you recommend looking for an issue modulo pulling the 2 cpu 
packages?
