According to a recent article, installing the attached "SSDT-PMC.aml" file into "EFI/CLOVER/ACPI/patched" will re-enable native RAM on B360, B365, H310, H370, and Z390 motherboards. It did work for me on both my "Mini ITX 3" and "Mini ITX 4" systems below. The article also recommended deleting some files after installation of the attached SSDT:
- /Volumes/EFI/EFI/CLOVER/drivers/UEFI/EmuVariableUefi-64.efi
- /Volumes/EFI/nvram.plist
- /etc/rc.clover.lib
- /etc/rc.boot.d/10.save_and_rotate_boot_log.local
- /etc/rc.boot.d/20.mount_ESP.local
- /etc/rc.boot.d/70.disable_sleep_proxy_client.local.disabled
- /etc/rc.shutdown.d/80.save_nvram_plist.local
NVRAM continues to work for me after deleting the above files also.
