    How to Add or Remove "Maximum processor frequency" from Power Options in Windows 10


    Processor frequency specifies the operating frequency of the CPU's core(s) in MHz. The higher the frequency is for a CPU, the faster the processor is.

    You can specify the approximate maximum frequency (in MHz) of your processor from within Windows 10 to limit the frequency if needed. For example, to save energy or the CPU is running too hot at a higher frequency. By default, the maximum processor frequency is set to 0 for unlimited allowing the processor to run as high as what is capable of.

    This tutorial will show you how to add or remove the Maximum processor frequency setting under Processor power management in Power Options for all users in Windows 10.

    You must be signed in as an administrator to be able to add or remove this setting in Power Options.

    i'm wondering if both options COULD COEXIST with mhz and the maximum processor state in %.
    the TITLE says to "add" Maximum processor frequency ( not replace) so i suppose that the maximum processor state will be there after the mod, or not?

    in the case the options both are coexistent, a user should be prident to calculate well, because ia 1000mhz cpu is set to max 80% STATE, but 900mhz FREQ, it would not be clear which one preset is used

    They are indeed two separate settings.

    One for the state percentage, and one for the frequency.

    ok but so the user should to the counting... because if set a mhz which is higher of the % of the cpu ... which one value windows will prefer? 80% of 1000mhz or 900mhz (it is an example)

    Both.

    The max mhz will be the highest allowed for the CPU. The max % will be the highest allowed for the max mhz of the CPU.
