I am pretty sure they have an EVBOT firmware version updated for the X79 DARK so would think voltages
should be correct but you might want to ask that question in the EVBOT section.
I know many here use AIDA64 to read voltages and temps and from what I have heard it is the most accurate out
of all the monitoring apps with the X79 DARK. I have been using it for years and has never failed me BUT
I don't have my DARK build up and running yet ..... soon.
My god man ... why so many drives? 3 sets of RAID 0 SSD's, 1X RAID 1 Raptors and a Back up 1TB.
Why don't you get rid of all those drives, get a decent size SSD for your OS (256/480/512gb), 'maybe' another
for your games (although a 512GB drive for OS would probably accommodate games and apps too)
and then maybe two HDD's in a raid array for storage and back up?
Just a suggestion, would also reduce all the cable clutter I'm sure those drives create.
Keep playing around with your OC settings, you'll get to a point where you will be happy and
you know if you need any help there are always people here to answer questions.
Can you post some pics of your build? Would love to see it with Nate's blocks in there.
