How to get frequency under 1Ghz when i'm not doing anything (idle) ? With config PluginType=yes and also KernelPM=yes, it just shows that iddle frequency are only at 1,3Ghz. I want to get idle frequency below 1Ghz, something like 0,8 Ghz or below it. And i saw the other people with i5-7200 also able to activate that idle frequency to 0,8 Ghz. And i hope this can be applied to my laptop too.

Thanks in advance

It is controlled by X86PlatformPlugin plists (FrequencyVectors).
You can patch it or even use CPUFriend to patch it, but you may have unwanted behavior (Apple may have chosen this idle pstate for a reason).

does this mean it's better to leave idle conditions like that instead of editing the frequency to be lower?

Maybe. For you to test if you want.

Read up on frequencyVectors, freqVectors.sh, and CPUFriend.kext.

Which one of method that leaving the vanilla kext untouched ? I don't want to patch that something vanilla in S/L/E

Install LiluFriend.kext and CPUFriend.kext into /L/E.

Already mentioned: CPUFriend.kext.
Why didn't you read about it before asking questions?
