Most likely your old motherboard didn't output the correct voltage from what the sensors and settings are indicating. I'v seen plenty of people switch from Asrock motherboards to Asus and they had to significantly raise the voltage settings to achieve the same overclock. When in reality, their Asrock bord was putting out way more voltage than it should have. Asus boards in my experience are very tight when it comes to voltage regulation.
Have you checked your Vdroop to calibrate the LLC properly? I know on my Asus z77 board I had to raise it a decent amount then it was a stable .003 volts deviation. On other Asus boards, they were out of the box regulating voltage within .002 volts without any LLC.
You can also go in the bios and check the PSUs output to see how close the voltage tolerances are to spec. If there is allot of fluctuation, you can expect some instability when you really try to push things. Corsair uses a mixed bag of PSU manufacturers on their products, so quality can range from outstanding, to absolute crap.
I was not trying to get 5Ghz @ 1.25 volts, I took it up to 1.4v and tried for 4.8 and 4.9 and could not boot into windows.
Based on my understanding I don't appear to have a Vdroop, infact I am 0.02v+/- over settings in BIOS.
LLC is set to extreme (thanks for the reminder), still unable to crack 4.8ghz.

Temp range from 39c - 75c under load, but I just re-applied the thermal paste so it has not stabilized yet.Edited by Thirdstorm - 6/19/16 at 11:12am
