ASUS ROG Crosshair VIII Dark Hero + Ryzen 9 5900X + RX 6800 XT

check the specific branch for the EFI files, currently 5700G branch is WIP.

• OpenCore ver 0.9.3
• MacPro7,1
• Ventura 13.4

Current hardware

Powerful and silent even under full CPU + GPU load (Thanks to external radiator).

Full hardware list:

• ROG Crosshair VIII Dark Hero motherboard.
• AMD Ryzen 9 5900X CPU.
• AMD RX 6800 XT GPU.
• Crucial Ballistix RGB 64 GB (2 x 32 GB) DDR4 3800MHz CL16 Micron B-die.
• SK Hynix Platinum P41 1TB TLC NVMe SSD (Windows + Hackintosh).
• Western Digital Ultrastar DC SN640 7.68TB TLC NVMe SSD (Games + Linux)
• Corsair HX1000i Platinum 1000W ATX PSU.
• ASUS TUF GT502 M-ATX case.

WiFI / Bt

The built-in components support WiFi 6 / Bluetooth 5 with the itlwm.kext and IntelBluetoothFirmware.kext, however, after Ventura, BT stopped working. Therefore, I switched to the Fenvi T919. Note that on Ryzentosh, in order for the BCM_20702B0 chipset to work, USB ports have to be mapped properly, and BlueToolFixup is required even for a PnP card like the Fenvi T919.

acidanthera/BrcmPatchRAM#28 made Bluetooth alive again on Ventura. Long live, Intel! As Apple has revealed in the Sonoma Dev Beta, Broadcomm is killed, and this makes it not worth it to get the Fenvi one for $59.99 as a PnP alternative. Despite AirDrop being not working, there is really no complaint for getting Bluetooth to work as I am typing this on my Keychron K14 via Bluetooth connection.

BIOS

Version 4501

• Fast Boot: Disabled ⁴
• CSM: Disabled
• Above 4G Decoding: Enabled
• Resizable Bar Support: Auto - This means Enabled on the ASUS board

Notes

Use at your own risk.

• All .efi drivers and .kext are -RELEASE builds from the respective packages.
• OpenCanopy (GUI boot menu) is up and running.
• I boot Windows 11 and Gentoo Linux using Opencore, thus I can guarantee it will work. I have Win 11 installed on the same SSD but Gentoo installed on an Optane P1600X that is disabled for this.

Good luck.
