Windows 10: CPU parking options in power settings

I added a registry tweak that unlocked the power option to park the CPU....

I am running a PC so battery life or power use is not an issue...

just want to be clear about the min and max settings....thought it would be just ON or OFF...
its the %s that confuse me....So if i set the min to 100% I assume that turns oof parking completely ?
If I set max to 100% this allows the CPU to go to the max it can ? So is the min setting for parking ? and the max to just restrict the max the CPU will run ?
If these assumptions are correct....what are the %s in between for ?

I have read everywhere about this and cant find a definitive answer.

thanks

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

 

Parked cores? Windows 10

At the time of your image the cpu was only 16% in use, so the cpu is not the source of the

perceived slowdown of you machine.

When more cores are needed they will kick in automatically.

Core parking is an important means for using less power, and helping the cpu to run cooler.

Unparking cores will not improve performance, in most scenarios.

I'm not sure if there is a definitive answer!
Rather, choose 'Balanced', 'Power Saver' or 'High Performance' in Power Options; Windows will take care of the rest.

After choosing one of the above, Task Manager will show you if any are 'Parked' or not:

 

Hi
I just want to know the effect of the % settings in the following




Here is my task manager....not showing the same display as your image

 

I couldn't be sure of the percentages of the different power states and their affect on your machine, you would have to set each and monitor them yourself.

To show individual processors, right click on the graph and choose 'Change graph to'►'Logical processors'
