I had no idea about this. Thanks so much for sharing.

First of all, thank you jcp-123 for this guide. I have been using it with success. Unfortunately I had forgotten to remove Windows Update, and, long story short, I had to reinstall everything.


I'm using the roughly same configuration (with D300 instead of D500 as internal GPUs and a Radeon 580X as the eGPU), and I use a Thunderbolt display attached to the port number 6 on my macPro.

I did the following steps :

- Install a fresh ISO of Windows 10 pro, build 1809

- Installed all the Bootcamp drivers from Apple (including the graphics drivers)

- Followed the dsdt procedure, succesfully compiled a source, and have the "Large Memory" item in my device manager.

- Uses the Display Driver Uninstaller and installed the latest version of the AMD drivers from bootcampdrivers.

If I start up the computer with the eGPU on, the Thunderbolt display stays black, and it doesn't seem to boot all the way (namely I cannot connect via VNC). And if I boot up the machine and after a while I boot up the eGPU box, then Windows does not see the external Radeon. Under macOS everything is fine, but Windows is not liking anything.

Is there a way to check that the eGPU is effectively seen by Windows, or is there a specific boot sequence to use for my setup ? Any help would be greatly appreciated (and the situation is really frustrating, a simple omission of a "do not ever update" on the registry has messed a particularly fine setup).
