Strange at 1.98 it can pass several tens of iterations and at 2.04 fails in several first iterations. I am testing at 1.9V now in the crazy hope of desperate
Next one will be 2.1V, if it fails, i may as well start to panic

Update:
12hrs of 4x prime95 blend, all memory tested, passed no problem 1.9V
Memtest86+ passed numerous times.
Yet my infiniband network card hangs almost immediately together with Linpack.
So much for this "memory tests"

Now for 2.1V, the last resort.
I'd put $10 on it that it's a chipset limitation, not memory. Increase vMCH and maybe VTT and see if it fixes stability.
