Update: Try linux-cpupower

I found this Q&A that may be of help: Is it possible to set a constant lowest CPU frequency under the modern PSTATE driver?

Summary of the answer:

sudo apt-get install linux-cpupower


sudo cpupower frequency-set -g powersave
sudo cpupower frequency-set -d 400MHz
sudo cpupower frequency-set -u 3100MHz

As mentioned elsewhere I don’t have an AMD processor and cannot test this for you…

I’ve been thinking of purchasing a Ryzen based system based upon leading-edge developments but I am still Intel platform based.

cpufrequtils comes up often on this site and it is designed for your AMD platform. From this Debian Article (Debian is the father of Ubuntu) install the AMD CPU utilities using:

sudo apt install cpufrequtils

Pay close attention to removing or overriding other governor utilities such as laptop-mode-tools.

If you have any questions post a comment below and I’ll try my best to assist with my limited knowledge of AMD platform.

Additionally, here is a detailed report from another user in Ask Ubuntu: CPU frequency scaling stuck 2.80 Ghz and it's not going down
