2600X running at 4.2GHz nearly constantly

[Malevolence]

No matter the load, hardware monitors show all the CPU cores to be sat running at 4.2GHz with random fluctuating dips down to 2.7GHz. Left it on the desktop with nothing but HW Monitor running and they were still sat at 4.2. Both Ryzen Master and CPU-Z show the same thing.

Was I wrong in assuming that it would be running at 3.6GHz and then jumping to 4.2GHz when needed?

It doesn't seem to idle though, it just sits at 4.2 across all cores at all times.

As above in the video, setting the Minimum CPU Power state works on my overclocked 1600, it down clocks to as low as 1.5Ghz when idle.

Nice one, never even thought of that. Knocked it down to the same value as yours (20%) and am now getting.
