I've been researching and looking up on 1.65v ram x79 platform. So far, it's only made me more confused. People are claiming that the IMC will burn out at 1.65v, some say it will run fine, and kingston hyperX beast runs at 1.65v at XMP.

So what is true and what is false??

I don't believe you would do any harm to your CPU running RAM @ 1.65v

You should be able to run your RAM at whatever it's rated for, ensuring its compatible with X79 Chipset. My 16GB 1866 Dominator kit run fine at 1.55v using XMP but changing Command Rate from 2T to 1T.

This 1.65v recommended maximum ram voltage has been around since they moved the memory controller off the chipset and onto the cpu. I read why this was so back in the day (something to do with max voltage/current the cpu to socket pins will handle) but have yet to hear of overvolting the ram causing a cpu failure.
