Umm yeah. Ryzens can handle upto 1.5v with very low current use, basically nothing more complex than websurfing. At high current use, it's down to 1.325v and even that is questionable as it depends on how much current is actually pulled. For a simple 4GHz OC, should be down in the 1.2v ish range.
HyperT2 is actually worse than the stock cooler. Lower wattage capacity.
80+ 500w TT psu?
Between the OC voltages, the cooler choice, the single 16Gb stick and the abysmal TT psu, I just gotta ask, I'm sorry, but do you not like the pc so much you are intentionally trying to undermine its potential or burn it up?
