I have no idea about this till now, maybe the ACPI table is different with Intel. Based on my experience, the x86platformplugin is not work for AMD platform, nothing happens even you make the driver loaded. if you looking for better power management for AMD CPU, you can try AMD Power Gadget...

I find some topic here about the wakescreen issue, seems need to modify some patch based on SSDT which is beyond my knowledge, maybe you guys can try it and see if the problem can be solved. @AudioGod...

yes, it is different with the most of guide. Anyway, thanks for you and Shaneee for the kindly help.

so far so good, I'm just complaint such weird motherboard...

OMG, it nearly killed me...

How should I do with MaciASL?

finally, I find that the _SB.PR00 works for my comp, but it is total different with the CPU name I see in Windows Devices Manager, any one can explain that? here is the workable patch file

what is the app name?

I think it should be _SB.PLTF.C000, right?

I just enable SSDT-plug-drtnia for a try, and it works.... I will try to delete the CPU name in SSDT-plug-drtnia one by one and see which item works.

nope... :( the x86platformplugin not loaded, and my CPU name should be _SB.PLTF.C000 not PR.C000

yes, I have made the SSDT-plug patch and added into ACPI folder but the x86platformplugin still not been loaded, and the power nap is missing

Apple CPU identifier must be 0x0F01(3841) for 8 core CPUs or higher and 0x0601(1537) for 1, 2, 4, or 6 cores.

Thanks for the guide, but I failed in making a workable SSDT-PLUG.aml by following this guide. x86platformplugin not loaded properly as before and here are some problems: 1. there is no "processor" can be found from my dumped DSDT file; 2. I find the CPU name is "_SB.PLTF.C000" in Windows...

It is weird that the SSDT-PLUG-DRTNIA.aml really works in my comp, the x86platformplugin loaded and the power nap appears. I find some articles said the SSDT-PLUG patch is only for Intel, if that is the fact do I still need such file? If I still need the SSDT-PLUG, could you guide me how to...

I just reset nvram via OpenCore but the nothing changed for the performance issue, it happens after I download SSDT-PLUG-DRTNIA.aml and added it into ACPI path to enable x86platformplugins, before that I have USBports.kext for my system and it works well for a few days. So I doubt if the SSDT...

Hi guys, My PC is AMD 5600x + MSI MAG B550 + RX580 + BCM94360CD, currently in Big Sur 11.5.2 with OpenCore 0.7.2. My question is when I wake up my desktop from sleep by clicking keyboard or move the mouse, the CPU/GPU fans start and power up my keyboard & wired mouse properly, everything...
