ECC memory would have caught any memory errors, (including memory 
timing), and give a diagnostic and we wouldn't be having this 
conversation, this system would be in production, and you'd be working 
on the next customers job.

oh yeah, those 'server' motherboards generally use registered/buffered 
memory, which can handle higher memory fanouts and support a full load 
of memory banks robustly.

I meant to suggest the other night, go into the Intel BIOS, find the 
memory settings area, and set it to custom timings, and add a clock to 
each of the timings, like if its 4-4-4-12, try 5-5-5-15 (or whatever the 
next increment is).     running 8GB on a desktop board, I'm guessing you 
have all slots full, this increseas the capacitive load on the address 
and data bus, and makes marginal timing more marginal.
