Hi guys I have an elite book 840 g1 which works beautifully on bigsur but on Monterey frequencies don't go lower than 1200.

I have cpufriend and also I put ssd-pm.aml in acpi in OpenCore to get all frequencies but Monterey does not won't to obey them...

Can someone  with more knowledge enlighten me in the proper procedure to achieve it??

No idea what files you need from me

I enclose my efi folder 

The photos is from bigsur you can see its working fine

MacBookPro12,1 is for Broadwell, you should go with MacBookPro11,4 for Monterey

You have too many patches doing the same thing, use one or the other, not both or all.

  • SSDT-PM.aml or SSDT-plug.aml
  • SSDT-data.aml with CPUFriend.kext or 
  • CPUFriend.kext with CPUFriendDataProvider.kext

hi did you generate it with ssdtime or you have used a prebuilt??

Do you frequencies go down to 800???

 

omg Jake Lo you are the best 

I just changed SMBIOS to 11.4 just used ssd-plug.aml and its great
