First you have to change the microcode from "Current Microcode" to "0x104 Microcode"
Doing this enables you to set an offset to "Global Core SVID Voltage" and "Cache SVID Voltage".
Leave "Actual VRM Core Voltage" on Auto!
Cinebench R23
Single: 2006
Multi: 23700
CPU-Z Bench
Single: 830
Multi: 9800
So pretty much the expected scores for a stock 13600K.
I set the offest to -150 mV because the latest Bios increased the stock voltage even further to around 1.4 Volts. Looks stable to me so far.
This thread over on Techpowerup pushed me in the right direction: https://www.techpowerup.com/forums/threads/colorful-b760i-frozen-wifi-13600kf-the-fivr-display-is-lo...
Should also work with B760-I. You don't have to use Throttlestop, but that's also an option.
Hope this helps someone.

Nice numbers, I cannot set offset lower than -0.040 V, it crashes/freezes at -0.050.
cinebench score with i3-12100 is 8300.
what is your power gain with that undervolt?

I can't tell you if this option is only available on 13th gen and/or unlocked CPUs. People reported on this option all seem to have a 13600K so far. Are you on the latest BIOS (2212)?
Beware, if you go past version 1620, you can not roll back!
The negative offset value depends on the stock voltage the mainboard sets for your CPU and the voltage your CPU needs to work properly.
I see a descent power consumption drop from 180W to around 145W in CB23. Overall performance is the same.
