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?

Idle speed will be lower .But you need to test for stability at 4.2. to could run for a long time like that, but something demanding will make it crash

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

^ Thats my 2600x logged over a couple of minutes while reading this and other threads, and preparing to snap a screenshot.

Processor cores are running default XFR / Auto with a 40mV negative offset applied and Ryzen balanced power plan in windows.
Most of the time the cores down-clock to ~3GHz, boosting to 4.2/4.25GHz when required.

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.

I tried this earlier to no avail, what other settings are required as mine didn't down clock.

Edit: I should say where is c6 state on gigabyte k7

You shouldn't be running the Ryzen power plan anyway, it's defunct and shouldn't be used. The fall Windows update included a Ryzen power plan. Just change you power plan to the Windows Balanced plan and you are good to go. By now you should be running Win10 1803, which will defo be fully updated to be Ryzen compatible.

Thanks for linking this, I'm running my 2700x at stock but I put it under an AIO recently & plan on trying out a bit of overclocking at some point.
