Above 4G decoding(This must be on, if you can't find the option then add npci=0x2000 to boot-args. Do not have both this option and npci enabled at the same time.)
- If you are on a Gigabyte/Aorus or an AsRock motherboard, enabling this option may break certain drivers(ie. Ethernet) and/or boot failures on other OSes, if it does happen then disable this option and opt for npci instead
2020+ BIOS Notes: When enabling Above4G, Resizable BAR Support may become an available on some X570 and newer motherboards. Please ensure this is Disabled instead of set to Auto.

[2023-4-10] tried to upgrade to macOS Monterey 12.6.4
- failed，because Monterey requires OC 0.7.4 or newer, from https://forum.amd-osx.com/threads/audiogods-gigabyte-aorus-x570-pro-pro-wifi-ultra-master-big-sur-monterey-beta-opencore-0-7-4-efi.1344/page-55
[2023-4-12] upgrade to Ventura 13.3.1
- Don't forget to update cpuid_cores_per_package as per https://github.com/AMD-OSX/AMD_Vanilla , since for >=13.3，a new cpuid_cores_per_package is added
