Why is the processor chasing by default?

Question

motherboards

Motherboard: asrock z370 extreme4
Processor: i7-8700K
It would be good to start overclocking and see what the temperatures will be, and only then manually overclock.
Reset all settings in bios. In A-Tuning (this is a utility for asrock z370 extreme4 mothers for overclocking), I turned off overclocking and even deleted it. Why do I not have a frequency of 3.7, but 4.4? Do I understand correctly that the mother should drive by default, that is, these are such frequencies without overclocking? Where does it even come from?

And it seems suspicious to me that the processor is Cofee Lake, and its alias is Kaby:
