I did not yet have Ryzen Master installed on this system (thanks to a recent SSD death I am still rebuilding). I then went into AMD's Profile Manager and selected "Gaming" as a profile setting. Games do not typically push the CPU to maximum, but the clock on my CPU fluctuated between 2.1GHz - 2.6GHz, with only occasional excursions. My 3900X has a base clock of 3.8GHz and a boost clock of 4.6GHz. CPU clocks during this initial test were surprisingly low. I hadn't previously selected a profile setting, so I kept everything on default for my first test. The ability to control and monitor system clocks is intended as a feature of AMD's driver software, but the point is not to deliberately overclock the end-users CPU without their knowledge. I happen to currently be running an RDNA2-powered Radeon 6800 XT and a 3900X, so I tested the problem out on my own system.
This doesn't appear to be happening in every case, but it may occur if you use one of AMD's Radeon profiles. AMD has acknowledged that its GPU drivers are also overclocking AMD CPUs in systems where Radeon and Ryzen are sharing space.
