It used to be fairly straightforward and linear but Skylake added all kinds of dynamics to it. Dunlop0078 is right on in that it boosts based on need and temperatures.
@Zerk2012 do you know of any confirmed cases where someone wasn't able to roll back to an older BIOS to over clock? Don't think I've ever seen any myself.
And you understand only a few motherboards with certain BIOS revisions allow this? Damric posted the list. Your own link is about the feature being removed.
The boost isn't something that works on Skylake processor's.

There is a microcode update in later BIOS revisions that prevent rolling back to older BIOS revisions on some of the boards Damric listed just to prevent overclocking non K processors.
I don't follow it closely but I believe there are a couple of boards left you can overclock on. You need a Z170 chipset in all of the cases though and most people buying a locked processor are doing so because they're on a tight budget so Z170 isn't a first choice for most of them.
So while overclocking non K is still technically possible it's not that easy unless you set out from an enthusiast perspective and it's just something you want to try. For 99% of the people asking about new builds on this forum it might as well not exist.
The "Intel locked this down" articles were just click-bait bunk posted by people that are too ignorant to try. These BIOSes were always beta and overclocking has never been officially supported. DO IT.
You don't need to adjust anything. As said above Turbo is automatic. Sorry your thread got derailed.
Your CPU will dynamically adjust its frequency based on need and heat among other variables. It will even downclock itself lower when idle to save power. All totally normal behavior.
