Then, I would play with CPU and VTT (QPI/DRAM) if still unstable.
Give it a try and report back.
I would be very careful with dram voltage at 1.65. Anything over 1.65 can damage the memory controllers on the chip and when I set mine for 1.65 I can get spikes over that so be careful and watch for voltage spikes. Just a heads up
