Make cpu frequency lower

[LordHung]

Hi, I want to make my cpu frequency get lower than 0.5Ghz. I think it can be around 0.3Ghz like my cpu freq in linux.
How can I do that? I have tried frequencyVectorEdit but how can I set frequency manually? Thank you.

Check into PikeRAlpha's freqVectors.sh script.

Thank for reply, I edited my Mac-{boardId}.plist with custom frequency vector data for my cpu. I checked with AppleIntelInfo.kext and now I see CPU P-State can go to 4 (before that it can only go to 5). So did I success or not?

At the early time when I install Sierra, I have followed your guide:

Do I really need the SSDT.aml generated by that script? Because I deleted it and now my CPU P-State can go to 4.

Thank for your help RehabMan.

CPU Ratio Info:
------------------------------------------
Base Clock Frequency (BLCK)............. : 100 MHz
Maximum Efficiency Ratio/Frequency.......:  4 ( 400 MHz)
Maximum non-Turbo Ratio/Frequency........: 23 (2300 MHz)
Maximum Turbo Ratio/Frequency............: 23 (2300 MHz)

IGPU Info:
------------------------------------------
IGPU Current Frequency...................:  900 MHz
IGPU Minimum Frequency...................:  300 MHz
IGPU Maximum Non-Turbo Frequency.........:  300 MHz
IGPU Maximum Turbo Frequency.............: 1000 MHz
IGPU Maximum limit.......................: No Limit

P-State ratio * 100 = Frequency in MHz

Thank for your help RehabMan.

Alternative is SSDT-PluginType1.aml as per guide.
