great thread man

i emailed Richard over at bit-tech about his claim to keep uncore within 0.5v of vdimm which will keep the CPU safe

Richard confirmed on email that Francois from Intel told him this about uncore & vdimm relationship during his interview

maybe something you should add in first post

here is what Richard wrote about it

QPI/DRAM Voltage - 1.35V: This is poorly worded by Asus - it should read uncore or QPI/memory controller voltage so not to confuse it with the actual memory voltage. Increasing this is also necessary as it helps overclock the base frequency as the uncore area overclocks increase in relation to the CPU core overclocks. This voltage is tied to actual DRAM voltage - the two are directly connected on the motherboard. You'll need to increase this to keep the CPU safe.

While Asus and Intel (rightly) scare everyone (read: uneducated) into thinking that 1.65V on the DRAM voltage should be the absolute limit before you reach for the fire-blanket, all that's really needed it to obey this: keep the CPU uncore voltage within 0.5V difference of the DRAM voltage and there's no problem. Over this potential difference and you’ll greatly increase the chance of CPU death, but it certainly won't happen instantly in a big ball of fail fire if you make a mistake.

DRAM Voltage - 1.66V: This is the closest to the 1.65V the Corsair Dominator DIMMs wanted and it's within the 0.5V Uncore difference.
