Questions on Ryzen 9 Speed Stepping

I'm currently trying to diagnose some thermal weirdness with my new PC build, and I'm suspecting that its my motherboard, but I have some questions on Ryzen turbo's and speed stepping.

 

A little pre-amble, my background has mostly been prebuilds and working on them and making them perform really well.  So a lot of intel chips, even though I really like the AMD chips, I just haven't been able to afford one until recently.  So, I expect some sort of speed stepping from AMD, right?  Well currently my processor is bouncing between 3.77GHz at 0.996-1.42V and jumping up to 4.5GHz.  If I turn turbo off I have none of these problems and my thermals don't climb.  Currently my PC isn't doing anything, its really just idling with vivaldi open as I type this out.  My motherboard is a gigabyte X470 Aorus Ultra Gaming, F42G bios.  Has anyone else had this happen?

 

Other thing is I'm fine with having turbo off, 3.2 GHz is honestly the fastest speed I get on a processor most of the time so 3.8 seems fine to me, but is it supposed to rest at 3.79GHz constantly?  That seems weird to me.

 

Any pointers are helpful, thanks.

the x470 aorus doesn't have good enough vrms to run a 3900x. so what you're seeing is probably vrms overheating and the throttling. can you monitor temps?

Even with turbo on VRM's rarely get hotter than 46 degrees.

Still wondering about this.  If its not a thing, ok.  I have the cooling for it.

Are you on a Windows high performance power plan? Accidentally disable downclocking/C-states in BIOS?

Hmmm no but mysteriously the CPU minimum in the power plan is stuck at 99%.  I noticed in one of Paul's video's that his 3900X was stuck at 3.7GHz as well.  I wonder if thats just normal.
