-
Install Windows 10 Pro as normal using the Boot Camp Utility. I used Win10 v2008
-
Let the Boot Camp Assistant install the standard drivers.
-
Reboot into safe mode and run DDU. I asked it to wipe AMD drivers. I don’t know if this step is required, however the guide this was based off did so I did it. Note that Bluetooth may not work in Safe Mode, so plug your keyboard in via USB for this step.
-
Reboot back into Windows as normal, and let all the Windows Update run. Several reboots will be required, so be ready to hustle that along. Whilst it’s downloading, go grab the latest AMD drivers but don’t install them yet. I used the Radeon Adrenalin 2020 20.9.1 from 16th Sept.
-
After the updates are completed, plug in / turn on your eGPU. It won’t work, but it’ll allow the AMD drivers to install. Painfully, if the eGPU isn’t connected, the driver app will quit as it starts with no prompt… annoying. I selected Factory Reset to “Yes”.
-
When the first stage of the AMD drivers has finished and it’s ready to reset, press restart and unplug the eGPU.
-
When the system is back at the login screen, plug your eGPU back in. This is important, as the AMD driver setup will continue when you log in, and if it can’t find the card, it’ll quit and you’ll need to start back at step 5.
-
When the installation is finished, click restart and again unplug the eGPU.
-
When the system starts back up, log in and turn on the eGPU. It’ll fail to start in the device manager however this is expected. Restart again, however as you’re restarting unplug the HDMI cable from the monitor that was directly connected.
-
When Windows 10 boots, you should be looking at your login screen through the eGPU. Huzzah!

@jazzdogg, There's progress with newer Windows 10 versions and glad to hear it's getting easier with Boot Camp eGPU setup (on a select few Macs). If you notice lower performance than expected, try Radeon Adrenalin 20.4.2 drivers.

Glad the build helped @jazzdog!
Are you using the latest AMD drivers direct from their website? I've noticed my only issue since moving to 5700XT and using the amended drivers is that streaming frame rates are _terrible_.

- @gizzer3010, crickey I haven’t noticed that yet. Streaming as in streaming your own screen to an online service?

@jazzdogg, tbh it could be using Twitch’s streaming app, but I remember getting better frame rate using my 580.
Did you download direct from AMD?

@jazzdogg, this may sound stupid, but when you say "When the installation is finished, click restart and again unplug the eGPU." do you mean unplug the eGPU as soon as you click restart or unplug it in the down time between switching off nad switching back on again? Because I would assume the former could cause a BSOD.
Great to see you have it working with a pretty simple set up! Would love to see pics...

- @eightarmedpet, either way works. I did it whilst Windows was shutting down. It won’t BSOD because it’s not running anyway. (Edit: removing the emote because the Smiley is creepy)

Hi,
I have the same configuration, Windows 10 installed and running on an external USB-3 disk.
When using it in normal office work it works fine, but when starting games I got a black screen
and the computer hangs after some minutes.
Any idea how to fix this?

@michael_behn, I played some War Thunder installed on a USB-C Samsung T5 last night and had no issues. Are you also running a Mac Mini 2018 w/ eGPU 5700 XT, except your W10 install is on an external USB volume?

correct.
I found the Problem. Semester to be a heat problem. I limit the frequency to 80% and increased the speed of the cooling fan. Now everything works fine. It‘s still fast enough with graphic Level set to high at FS 2020
