Been tinkering around with undervolting my 13700k and most people I’ve seen online seem to think their chip can easily be consistently stable at an negative offset of -0.135. Mine on the other hand becomes unstable at -0.080. Also whilst running cinebench wont push past 4.5ghz. Am I missing something here?

Max temps and scores so far on cinebench are as follows: Score 26k Temp max 87 degrees

    Nobody’s CPU is stable at -0.135. If they think their CPU can run with that aggressive of an undervolt they’re either not testing it correctly or their default motherboard calibration is absolute trash.

    Realistically, these CPUs aren’t truly stable past -0.050 undervolt. There’s some randomness but there’s less than you think since the motherboard will always attempt to adhere to each CPU’s individual VID and the VID accounts for the silicon quality.

    A better binned CPU doesn’t always mean you can undervolt it further, it means it’s baseline voltage is going to be lower at a given frequency. How far you can undervolt is mainly dependent on how accurate the motherboard’s calibration is.
