hi @rrysio6 You have to use an opencore debug version to extract your DSDT Then, in your Config.plist misc/debug section you have to enable SysReport option When you try to boot frm opencore menu you should find in your EFI ppartition a folder named Sysreport ACPI folder inside is the one...

@rrysio6 those ACPI patches in your config.plist are done for your motherboard? you should post to CorpGhost your DSDT on amd OSX discord server if those patches are not for your motherboard Asus has 4G in its bios (you have to enable it) More important is to use exact ACPI patches for you...
