24/7 Overclock, OK for 4 weeks now. Prime and LinX stable. I went ahead and raised the vDIMM after the Corsair Dominator decided not to play nice at 2000 (v3.2 Micron). I managed to tighten up the timings, seem to get flaky below 1.73 so I left it at 1.74. I am going to politely ignore the 1.65v warnings for now.
