This follows on from my thread here: https://forums.overclockers.co.uk/threads/asrock-extreme-4-vcore-reading.18825307/
Which begs the question: With your pre-binned chips it says, for example: "*Guaranteed minimum overclock of 5.1Ghz with an AIO 240mm cooler with 1.35-1.425v*", is this BIOS/software reading or physical (multimeter) readings?
Reason being my ASRock Extreme 4 with a 8600K gives a difference between the output from the PWM and software of about 0.06-0.08V, i.e. if the software shows a load voltage of 1.408V, the multimeter shows 1.498V(!). Some of the difference in HWINFO seems to be that the Vcore shown increases in 16mv steps which doesn't help...
Could you make some physical readings of Vcores for your binned chips to confirm the voltage they are actually receiving?
I'm fairly sure I can get this chip Prime95 stable at 5GHZ if I use the software reading, but I'd need ~1.5V physical reading which is too high given Intels spec...
I've dropped down to 4.9Ghz and 1.4V physical reading in the mean time. (~65C load)
