Error 173 with Windows BootCamp on iMac 2017 and Radeon RX 5700 XT
Unfortunately, I still get Error 173 (hardware not recognised) when installing the AMD Drivers . The Windows drivers recognize the Radeon Pro 570, which is installed in the iMac , but the Sapphire is shown as "Microsoft Basic Display Adapter" in device manager with a yellow exclamation mark.
The fans of the eGPU do work, though, when it is plugged in.
I did try using Windows 1903 instead of the newest Version.
Does it have to do something with the fact that the Razer Core X is plugged into the iMac and that there is no external display? Should I maybe try connecting the graphics card via Displayport to an external display?
Thanks for Your help!
@mac_editor, I deleted BootCamp Partition and reset it, installing the old Windows 1903 version as You describe in Your 8-Step guide here on the forum. That should have deleted all drivers, shouldn‘t it? I did try with the AMD drivers then before trying to download the latest BootCamp driver. Do You think, that makes a difference?
