Apparently only Windows or AMD’s drivers didn’t manage to do that. And unless the BIOS defaults are loaded the "Auto" mode doesn’t do what you expect – if you’ve set an overclock previously.Ĭuriously enough, booting Fedora Linux from an USB stick did properly scale the CPU frequency based on the load, even with the overclock applied.

The same setting only with a different clock value produced a different behavior. When setting 3400MHz it properly clocked down and also boosted as a R5 2600 should. When applying the overclock with 4000MHz it effectly ran at 4GHz every time, even in idle. Enable manual control and set the correct CPU base frequency at 3400MHz.There’s a weird bug in the BIOS that still applies the overclock even if the setting is set to "Auto by AMD CBS" (or something like that). It is not recommended to upgrade unless a Ryzen 3000 is installed. I have an ASRock B450 Gaming mITX mainboard with the latest non-Matisse (Ryzen 3000) BIOS. It was the frickin’ BIOS! Ryzen Master was not to blame. More reboots and tests with BIOS settings.Getting pissed and searching the Internet – apparantly I was not alone.Notice CPU always at 4GHz, no more Cool’n’Quiet operation mode.

Reboot to Windows and reset everything in Ryzen Master.
