  2. processor power management optimization

    ive been playing around with the processor power management options for quite a while already since i noticed that my old notebook's cpu (i7-720qm) struggles with running on full power (mainly due to heat i assume).

    i already managed to optimize performance quite noticeably, but some of the settings are not fully clear to me resp. their default settings are quite confusing, even contradicting to their descriptions.

    so if there is somebody familiar with processor power management - ie. idle and performance states and their respective settings, some explanations and recommendations would be highly appreciated.

    my main aim is to make the cpu run on as few cores/threads possible, clocked as high as possible, before unparking additional cores/threads. ie. to be highly responsive for just a few tasks rather than manage multiple tasks simultaneously, and not getting
    throttled because too many threads get unparked although just a few - but clocked high - would manage it better. mainly because most of my tasks much more require few but high clocked threads than more parallel processing.

    here are the settings i have set currently:

    processor performance increase threshold - 30%

    processor performance core parking min cores - 13%

    processor performance decrease threshold - 20%

    processor performance core parking concurrency threshold - 95%

    processor energy performance preference policy - 20%

    allow throttle states - off

    processor performance decrease policy - ideal

    processor performance core parking parked performance state - no preference

    processor performance boost policy - 100%

    processor performance increase policy ideal - aggressive

    processor idle demote threshold - 30%

    processor performance core parking distribution threshold - 90%

    processor duty cycling - disabled

    processor idle disable enable - idle

    processor performance core parking decrease threshold - 60%

    processor performance core parking decrease policy - ideal

    processor idle promote threshold - 50%

    minimum processor state - 50%

    processor performance autonomous mode - enabled

    processor performance core parking overutilization threshold - 80%

    system cooling policy - active

    processor performance core parking core override - disabled

    maximum processor state - 100%

    processor performance boost mode - aggressive

    processor performance core parking increase policy - ideal

    processor performance core parking increase threshold - 80%

    processor performance core parking utility distribution - disabled

    processor performance core parking max cores - 100%

    what confuses me a bit are the default settings in power saver & high performance profiles of

    processor idle demote threshold - ps: 20% / hp: 40%

    processor idle promote threshold - ps: 40% / hp: 60%

    judging from their descriptions, i would actually suggest them being exactly opposite?!

    any suggestions on these two options resp. how to optimize the power settings better to achieve what i explained above - as few cores/threads unparked as possible, clocked as high as possible, before unparking more, without capping
    min/max states or preventing threads from parking/unparking completely?

    thanks

  3. Windows 10 only use half of max cpu speed

    Follow this thread, add back min processor state and max processor state to Windows power options.

    Power Options - Add or Remove "Min/Max processor state"

    Open Windows power options and change the Max Processor State from 50% to 100%, Win10 default 50%.

    Then, the CPU frequency dynamic range can be exceed 50% ceiling.
