It could be the case that your system ‘thinks’ it can do the job with that stepping.
Apart from the power profile, I use Throttlestop Download ThrottleStop (9.7.2) | TechPowerUp
The setting ‘speed shift - epp’ is for me the most important one: setting it to 0 (zero) means that you want performance instead of efficiency.
There are a lot of other settings (also cpu voltage related), but I wouldn’t go there unless you really know what you’re doing. I leave them alone.
