Fixes to Get Full Hardware GPU Acceleration using Intel HD Graphics with AMD RX480 on SMBIOS iMac 17,1 and MacOS High Sierra 10.13.0 Z 28-10-2017
First draft.
Hardware
Gigabyte Z170X-UD5-TH/i7 6700K/SSD’s/32 GB RAM/MSI AMD Radeon RX480/8GB Gaming X.
RX480 connected to 2160p monitor using displayport, HD530 used for Intel quicksync. QuickTime player screenrecording and h264 export from FCPX work
Audio over DP works
Not a complete guide for a successful iMac 17,1 installation on the Z170X-UD5-TH. I’m showing just the relevant parameters in the BIOS to make the RX480 and HD530 work, for example.
Luxmark 3.1 ball benchmark: normally about 16000.
Sleep is not working well on my system, but this is due to the USB3.1 ports that have not been properly patched(any ideas how to do this are most welcome)
Maybe there are too many patches and SSDT’s in place
BTW, still using HFS+
BIOS
version F20
