You might want to review why you have multiple SSDT tables loading.
Also you can get GPU PM by renaming GFX0 to IGPU in DSDT.

Hmm.. I only have the one SSDT in ACPI>Patched (Clover), however it was named SSDT-4 for some reason. I have reverted it to simply SSDT.aml. Might that have been the issue?

I also edited my DSDT to include the change you outlined.

I have attached an updated IO registry file in case any changes are reflected in it.

You probably have Clover set to generate SSDTs for pstates/cstates, so you have duplicate info... Check your config.plist and be sure Generate/CState/Pstate is set to false.

That should do it?

If that is under SSDT, I think so... Use Clover Configurator to be sure.

Made those changes using Clover Configurator, just to be sure.

Updated IOREG file is attached.

Has that helped in any way? The battery drain is/was horrible.

*Update - since I implemented those changes my speed stepping seems fairly limited and stuck between two states.

Or is that how it's supposed to work?
