Hello, I just implemented the instructions on my setup and just wanted to know if it worked, cause I personally have no idea to find it out myself, sorry.

Here are all the details:
1. Sierra 10.12.5 / H97M-D3H rev 1.1 / F8b / Intel i3-4160 / HD4400
2. IOReg copy attached below
3. AppleIntelInfo attached below
4.Config.list attached below
5. Intel Power Gadget screenshot attached below

According to ioreg, CPU PM working...

I have downloaded the "ssdt_lpcb-9series.zip" and it has the SSDT-5.aml. The instructions state to move it to EFI/Clover/ACPI/Patched

Does it require me to extract all the platform SSDTs and place them there too? (of course, apart from the SSDT-5.aml) Just want to learn and clear my doubts.

Update: After leaving my system alone for a few hours, the CPU is now running better with XCPM; all the way down to 0.8GHz! No idea what could've changed, though. System was idle during my testing.

I'm having a problem(?) with this power management. For some reason, it causes my CPU to run at max more often with XCPM than without. I also have more power states without it. I don't know if it's something that needs fixing, though. I have verified that IOReg does contain the CPU power states when XCPM is loaded (in X86PlatformPlugin) and doesn't when not loaded.
