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.
