Skylake-X - running an i9-7980XE at 1.425V VCore 24/7
So looking at Intel specs, the maximum input voltage (Vccin), Vccio (supply for processor i/o), and Vccsa (supply for integrated i/o controller), are all specified as 2.15V, 1.35V, and 1.35V, respectively.
However, the maximum per core voltage is somewhat nebulous. I am currently sitting at a 4.9 GHz overclock at an all Vcore voltage of 1.325V (1.825V Vccin). Getting to 5.0 GHz all core performance will require a core voltage across all cores of 1.425V.
The question is: Can I get 5 years of life out of this CPU if I run it at full load, 24/7, at a core voltage of 1.425V, assuming that I keep core temperature at or below 80 C?
Is this within the realm of possibility, or will the CPU be partially and/or fully dead in a much shorter time frame due to electromigration and other effects?
It looks like there is a treasure trove of other info with regard to Skylake-X overclocking that is slowly building up in this thread that is unrelated or only tangentially related to my original question. If you are in the process of overclocking your Skylake-X CPU or trying to get the most out of your CPU/MB, you may want to give this thread a quick read-over and see if you discover some proverbial diamonds in the rough.
