I saw the announcement of the new utility also. No help for us Linux users. We still have to find the individual CCX stable voltage points through experimentation. Good for Windows users. All automatic.

Hmmm

An article that may be of some use to you is here AMD Ryzen 3000 Undervolting Offset vs. Override | Vcore Voltage - the video in it talks through the article.

Thanks for that, a very interesting article - a shame that they chose such a ridiculously low fixed voltage for their comparison, I’d have thought maybe 1.2v would have been more appropriate.

Certainly would, though it was triggered by an article talking about 1.0v.
It would also have been interesting to see data for 1.1v, 1.2v and 1.25v to get an idea of where the inflexion point was, as well as 0.05v, 0.10v and 0.15v negative offsets

But anyway, you have a lot to go on and it looks like you've had a fair bit of success already. Good stuff.

Eventually it will, the standard k10temp driver for AMD and Ryzen processors gets updates in the HWMON branch at every new kernel release. The zenpower and RAPL coding has been brought into the k10temp branch for voltage and power readouts.

So in later kernels, you won't have to do anything extra or use an out of tree driver to see those sensors. You will be able to see them just by invoking sensors in a terminal. You still have to pick your poison in regard to a desktop GUI monitor if you choose to use one.

And more is coming for the Zen2 Ryzen's https://www.techspot.com/news/86498-upcoming-free-software-brings-more-performance-lower-power.html

Wow, that’s almost enough to make one consider moving to Windows.

You can accomplish the very same thing in Linux. Just not automatically with a single click. The concept was defined and experimental result posted in the OCN Ram Calculator thread. Just run several instances of Prime95 at fixed VID voltages for each CCX complex to find how far you can push each CCX and be stable. Then input the per CCX VID get voltages for each CCX in the BIOS.

You still have to input all that information after running the Windows utility. Just like you need to do in Linux. All the utility does is script the several Prime95 runs it needs to do to find the max CCX clocks and the required voltages.

OK, thanks - I'll look into it.
