First of all, thanks for this great thread @Gigamaxx, and to all those who have contributed to it. It helped me decide that my next graphics card was going to be a 5700 XT.

I was originally going to buy a Sapphire Nitro+ 5700 XT, but the MSI Gaming X 5700XT was slightly cheaper here in the UK. I've not seen many others using this card, but I figured I could always send it back for a refund if things didn't work out.

Luckily, the card has been great. :thumbup: Thanks to this thread, I knew I needed to have "agdpmod=pikera" in my boot-args and, along with WEG, this was used to successfully boot into macOS. I'm running OpenCore 0.5.4, and my new GPU's been working fine so far. It's also extremely quiet under load, and has the semi-passive fan mode I was looking for.

About this Mac details, and Geekbench OpenCL score attached (iMacPro1,1 SMBIOS).

iStat sensors for the card are probably giving the wrong reading. It’s new and GDDR6 which is a first for MacOS.

Hello! Sorry, if my English is bad.

I have installed Catalina 10.15.2, good working with IGPU.

I try to run with my Sapphire RX 5600 XT Pulse (using Lilu, WEG, agdpmod=pikera and diferent SMBIOS). But I get this error:

Can someone help me, please? Do you have any idea?

Or 5600 XT is not working?

Disable IGPU in bios.

I already have set BIOS -> Advanced -> Integrated Graphics Configuration -> Initiate Graphic Adapter to PEG (instead IGP). Is that what you mean?

What other ideas do you have?

No. I do not see such an option.

Probably, IGPU disables automatically when а graphics card is installed.
