    I am getting a new system with an i7 9700k CPU. It is advertised as 3.6 GHz and 4.9 GHz in turbo mode. How will I switch between the two speeds and how will I know which one is active?

    Turbo should be enabled by default.

    As for the maximum turbo mode speed, that depends on how many cores are in use. That varies from 4.9 GHz when only a single core is in use, 4.8 GHz when two cores are being used, 4.7 GHz with three or four cores used, and finally 4.6 GHz when more than four cores are in use.

    You don't need to do anything.

    IMO the single core turbo speed is almost meaningless cause usually at least 2 cores are loaded

    And in the history of turbo'd Intel CPUs, there have been a few that stayed at stock non-turbo speed when all cores are loaded. And there may have been a couple that stayed at stock non-turbo speed when more than two cores are loaded.

    Not sure I follow what you’re saying. For most current gen CPUs you can find the turbo tables on chip wiki or Wikipedia.
