Dear
@CaseySJ,
I have installed my RX 580 and with AMD config and my icloud registered SMBIOS parameters booted without any problem. I used
https://hackindrom.zapto.org/ for copying SMBIOS.
My bios settings are iGPU enabled, and initial graphics output on PCIe 2. (where RX 580)
I am trying to monitor GPU usage via Stats (exelban).
I have tried two setups;
- RX 580 displayport out connected to MB display in, monitor is connected via Thunderbolt 3 out of MB
- Monitor is connected to the RX 580 displayport
In both setups, iGPU is not taking any load for PDF rendering etc. All load is covered by RX 580.
Do I have missing some thing ?
Best
