@susurs, I would say to use Windows 10 1903. The newer Win10 versions don't always work with an EFI boot loader. Since your Mac mini only has iGPU, use original drivers from AMD website. You can take a look at my 2018 Mac mini + RX Vega 56 Gaming Box build for reference [build link].

Thank you! I can try that. There seem to be some differences for 1903 as well. Is V1 supposed to be the best?

@susurs, Yes Windows 10 1903 V1 ISO is the one to use. The build version should be 18362.30.

@itsage Still not working.... 🙁

I tried Dev channel W10 update 21296 - still error 43.

Then I wiped the drive and installed 1903 V1 - the same (Error 43 after installing drivers)...

I have no idea for anything else...

P.S. The card boots fine to macOS, is reported correctly, works on internal or external hdmi. I tested some graphics benchmarks like Basemark GPU, Unigene on macOS. Everything is fine and as it should be as far as I understand.

Hmm... I found a note no Sonnet’s webpage saying RX 5500 / 5700 requires latest release W10 20H2. Not sure, however, whether that applies to Bootcamp as well, or Windows machines only.

Also, not sure on what they mean with ‘latest’ as well - just 20H2 or latest build of 20H2 as there seem to be some updates to that version.

(On the product page itself it says ‘not certified’ for use under Windows.)

YeH, like I said, I got my 5700 XT working on 2004 (and without any software hacks, boot adjustments, etc.). I’ve heard that 2004 is much friendlier with eGPUs, and am inclined to believe them when they say 20H2 is required. I suspect that the idea that you have to use 1903 or files from it is a holdover from when the much less friendly 1909 was the latest version.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

@cptnjustc It might be but I wonder what specific advantage would there be in 20H2 as a requirement for RX 5500 / 5700. 

I thought of trying to install W10 on an external drive, and plug it into Mac Mini’s TB port or even directly in eGPUs second TB port for an experiment. As Code 43 could (maybe) be related to some bandwidth issues (not sure), maybe that would change something. Just a wild guess as I have not a lot of other possible fixes for now to try...

This seem to be an interesting statement as well (Code 43 on drivers above version 19.11.3.):

Yeah, dunno why 20H2 would be required, but If real, I’d suppose it would have something to do with the interface to Sonnet’s enclosure rather than the GPU itself.

I tested again with 1903, 1909, and 20H2 and old drivers. Does not work. I noticed that Windows 10 has a tendency to auto update the driver to newer version at some point even if this option is switched off in settings.

1903, 20H2 - ‘Code 43’. With 1909 the only difference was that I could not ger rid of ‘Code 12’.

I noticed that when I launch AMD’s driver installer and there is a driver installed already, the ‘Code 43’ goes away even if I do not press install driver. However, GPU-Z still reports the card without speeds, and the card does not get enabled. Restart is needed probably, and upon restart I get ‘Code 43’ again.
