Nice nice ...
BTW on my system I have to
- deactivate only C-States (C0/C1)
- leave Turbo and Speed Step on
then I can control the rest in Windows (CPU core parking, clock) simply by selecting one of the three power profiles.
Then in windows select power profile: "High Performance (EN)" or "Höchstleistung (DE)".
With a Xeon E5-1650v4 CPU (3.6 / Turbo 4.0 GHz) this leads to a constant clock slightly higher than base clock (3.6) and a little slower than Turbo (4.0) => 3.8 GHz.
You need to observe then with tools like e.g. HWMonitor (which is quite nice as it shows clock per CPU core) whether the clock is stable or whether it changes. If its stable then you should have the benefit as well running with a little higher clock rate compared to base clock.
But please check whether CPU temperatures are still fine, this you can also observe with HWMonitor.
You need to run it as administrator to get more details: https://www.cpuid.com/softwares/hwmonitor.html
Then you can tweak it even a little further with tools like parkcontrol: https://bitsum.com/parkcontrol/
Sorry this one only in German but look at the pictures, there I did some fine tuning for the older CPU model that I
had, the E5-1650v3 (Base: 3.5, Turbo: 3.8 GHz).
Depending on the Windows Power Profile I can select CPU core parking and clock speed:
High Performance: no cores parked, full clock
Balanced: 50% of cores parked, at least 1,9 GHz clock speed
Power Saving: as many cores as possible parked and a minimum clock speed of 1.2 GHz

I tweaked then this even more by making use of special features of Process Lasso Pro:
Performance Mode and Idle Saver
My default Power Profile is "Balanced".
If there is no user activity (Mouse, Keyboard) for e.g. 15s (configurable), then it enters automatically "Power Saving" mode.
As soon as I start working again, the energy profile switches to the currently set which is balanced.
Then for certain applications where I want 100% performance I can configure to enter an energy profile for high performance. To ensure, that IDLE saver does not become activated I need to select not only a higher energy profile for such applications but also a "flag" Performance Mode. This mode hinders that IDLE saver becomes active.
By this I have a full automated selection of power profile based on the applications that I use.
And in the evening its quite nice, when I use the PC only for casual internet browsing, that I get a sufficient performance for internet browsing (as it stays in power profile balanced) and as soon as I continue watching TV, then PL Pro's IDLEsaver feature takes automatically care to select Power Saving as lowest energy profile.
Applications like cubase can activate their own energy profile or you choose "Bitsum Highest Performance", which Bitsums own Energy Profile to ensure highest performance.
This article is a little older, meanwhile I selected a little higher clock for "Balanced" but am still parking 50% of cores.
Not 100% sure but in a good case of luck these 50% deactivate exactly the Hyperthread cores ...
Under Windows 7 I could notice that every 2nd core (the hyperthreaded cores) became deactivated.
Under Windows 10 the behavior of these Gadget tools for CPU changed a little, not sure whether Win10 is different in that regards, but I do not care too much.
PL Pro has btw also a steam detection, so that Bitsums Highest Performance is automatically being selected as soon as you start gaming. It gives you really some extra comfort options and even some more.
Don't get me wrong, I do not see a necessity to use PL Pro .. I only wanted to give you an idea whether this would also be of interest for you, that your PC can save some energy, if you are not recording or of you are away from the keyboard.
