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

you have to control (Lite load settings (AC/DC) + LLC settings + Offest) to use very high offsets,…if you set LLC 7 (default in MSI) you cant reach more than -0.050 offset mostly ,. so try to compare other’s undervolt with vcore on load value ,. it give more accurate undervolts
It could also just be the silicon lottery. Some people get lucky so there cpu might either overclock better or unvolt better but it could be you aren’t as experienced so you could be doing something wrong.
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.
hii,. this is how i use -0.130 offset with my 13600k ( https://imgur.com/a/p9AUnzo ) ; i use LLC 3 (near straight)
For the V/F curve in tweakers paradise my 14900k is stable at -0.1V for all 11 steps, not sure if it’s the same as I’m new to Intel.
I dont think 13700k stable at that low offset, I have personally tried and -0.065v offset is ideal in terms of temps and performance
