VCO change is available since 85b1e626183986c3bdfcc9b2bb046e8f24a13882 in develop
branch
If you have chosen the Voltage Optimizer within BIOS option then you have to specify HWM_CHIPSET=AMD_VCO
to get an appropriate voltage Core reading.
Please post screenshots of the UI View > Sensors > Voltage
in various cases: Idle and Stressed CPU (not showing Menu)
Tips:
make -j HWM_CHIPSET=AMD_VCO NO_UPPER=1
Thanks anyone for helping

Do I do this while having curve optimizer active, or not active?

You do this while having curve optimizer active
Ok so i cleaned and rebuilt with make -j HWM_CHIPSET=AMD_VCO Im using a CO in bios of -20.
Here is idle voltage view:
All core stress using your software voltage view:
@madoverlord40 Thank you for your tests. CO is really odd: from idle to stress, the VID
delta is just about 4
for most cores.
And unfortunately 9950X
results don't behave as 7950X
ones
VID
to voltage formula has to be customized directly in source code and as a function of the curve parameters left in BIOS

Now BIOS can be configured with no CO, voltage offset and tweaks. Just the plain P-State. PBO is ok.
A simple make
(without HWM_CHIPSET
parameter) will now build CoreFreq with standard formula: please let ne know if voltage is accurate
Not using Curve Optimizer. Using per CCX with 52.0/50.5 @ 1.28 VID Here is idle and stress screenshots under my Boinc load.
I still have CO on and have not testing with it off but as having curve optimizer on at -20 and level 5 CPU LLC in bios, i dont think this voltage is correct?

For this screenshot how was made the build ?

When CO is activated, the VID
values in both case, idle and stressed, are so closed that it can't compute the low and high Vcore!
Let me show you what we have with Zen2/Matisse
Idle case
All CPUs stressed
Single CPU stressed
The VID
values (obtained from current P-State register) are inversely proportionate to the frequency
Applying the voltage formula (specified in AMD datasheet), we are getting an accurate voltage (for both CPU and SoC)
Vcore = 1.550 - (0.00625 * VID)
Vcore = 0.00625 * VID

I think its still built with HWM_CHIPSET=AMD_VCO.
You know i think these voltages im getting right now are good, not that i know what the formulas should be. But i rebuilt with just -j on develop, and then started to build HLOD in unreal engine 5, and voltages were between 1.29 and 1.36 while boosting. Seeing that i have a CO of -20 and LLC of level 5, its doing well. Even if the voltages are not correct, they are i think quite close!
Yeah, its close, im in RM now during a C++ all core compile, RM is averaging 1.33vcore, you are so close!

Great to see that.
make -j
brings the default voltage formula.
I'm going to merge last commit into master
Thank you for your help.
For AMD Vermeer, Raphael and Granite Ridge is introduced the VCO formula as a build argument:
Remarks:
HWM_CHIPSET
argument, the CoreFreq build will fallback to the AMD P-State voltage formula.
