Threadripper 1920x and post overclock dynamic frequency

[Axiomatic345]

I overclocked my 1920x to 4.0GHz at 1.325v and although the overclock seems stable and idle temps were at 27C and max during cinebench etc 67C, what I am noticing is the CPU always shows at 3.99 or 4GHz and it does not downclocks when I am not doing anything.

 

I am using ASRock x399 taichi mobo. Is it possible that this is Operating System thing?  Is there any post overclock steps to do with threadripper to ensure lower power use when I am not stressing the CPU much.

That's not how overclocking works. When you overclock, most power saving features are automatically disabled causing all cores to stay at maximum frequency. However, idle is idle, if your computer is not doing anything, then it's not consuming great amounts of power.

If I'm going to be idle for a while I change the cooling policy to passive and set the minimum frequency to 20% or something like that. Clocks drop to 2.2GHz and power usage drops quite a bit. You could also achieve this by switching to the Power Saver plan.

Coming from Intel platform. One can actually disabled fixed frequency and enable adaptive power to take CPU to lower power states when just browsing or not doing anything taxing.

There's a good chance I'm wrong, it's been known to happen.  I've changed so much with my power plans testing new things and attempting to verify my answers before posting, I need to uninstall my Ryzen Balanced Power Plan and reset the Windows plans to defaults.
