0. Start with a fresh installation of Windows 10 Build 1803. (It may work with another build or not-so-fresh installation, but this is confirmed. And this is best way to avoid dreaded Error 12).
A) nVidia cards:
1. Hot-plug your eGPU on a running windows system into the right side TB3 ports.
2. Give the system some time, at least a couple of minutes, it will install the drivers by itself.
3. Finally your card will appear in Device Manager under "Display Adapters", but yellow banged (Error 14 or 43)
4. Right-click on it and "Disable device", followed by "Enabled device". No reboot necessary.
5. Finished. If you have an external monitor, it will display a windows desktop.
6. Before you boot next time => go to Step C7!
(Note: With nVidia cards Step C7 can be avoided, by unplugging the eGPU during boot and hotplugging it after Windows is fully loaded)
B) AMD cards:
1. Download AMD drivers von bootcampdrivers.com
(Important Note: Why bootcampdrivers drivers? Because standard AMD drivers (eGPU) and Apple AMD drivers (dGPU) collide, bootcampdrivers support both.)
2. Reboot your system into Safe Mode. ("Change advanced startup option" -> "Restart now" -> Option 4/5)
3. Uninstall all AMD Drivers with the Tool "DDU" which is coming with the Bootcampdrivers.
4. Install Bootcampdrivers downloaded in 1, "Radeon Pro Series" will appear under "Display Adapters". Reboot without eGPU.
5. HotPlug eGPU => AMD eGPU will be yellow banged with error 12.
6. Reboot, but before you reboot => Go to Step C7.
C) AMD+nVidia: Preparation that internal display will be working after reboot:
7. Uninstall the eGPU directly from Device Manager: (Do not delete the drivers)
8) Reboot immediately. Done:

Hardware: mid 2017 15"MBP Radeon Pro 555 model, with HP omen accelerator, the best I Can tell is my Omen is basically non responsive when plugged into my system at any point. This is in bootcamp as well, is there any fancy step to getting the system detected?

How are you connecting the 5k to your laptop? Through the eGPU video card? or through your Laptop?
In any case, I never thought of this! I will definitively try it!

Hmm, I've noticed this method seems to work for me initially (most of the time). However I've found after a period of about 10 minutes the whole Windows 10 OS seems to freeze / lock up. Has anybody else experienced this behaviour before?
Strange as when testing this the first couple of times it wouldn't lock up after any time period.

There are two ways.
1) Using the Software DDU (the safe and recommended way)
2) Uninstalling from DeviceManager, it is not what is displayed in the screenshots, but similar and you have to check "Delete the drivers software for this device".

When you hotplug your eGPU, it is automatically detected. Sometimes the system seems to stop, but only for a few second and then it's normal again. If your eGPU is not detected or your system doesn't respond anymore, there is something wrong with either software or hardware.
@mac_editor, are there any news on an automatically uninstall of eGPUs on shutdown?

@oliverb haven’t had time to work on it further. Dealing with a busy college schedule at the moment.

Thank you very Much I'm Presuming there is something up with the Enclosure itself, HP released a Firmware update for it to address this sort of issue but without the station being detected let alone the eGPU it makes it a little difficult for me to update the firmware but ill find a way.

Hi everyone,
I followed these steps and was able to get my Vega 64 to work properly on my 2017 MBP 15", with an external monitor. My only (large) caveat is that I'm unable to use an peripherals - about 30 seconds after I plug in a mouse or keyboard, the computer freezes and requires a restart.
I'm plugging the EGPU thunderbolt in the left side of the computer on its own, and attempt to plug my mice/keyboard on the right side.
Tips? Is there a USB controller that I need to install/uninstall/disable in device manager? I see these by default, but aren't sure if they're at the root of the issue:
1. Apple USB Composite Device
2. Intel(R) USB 3.0 eXtensible Host Controller - 1.0 (Microsoft)
3. USB Root Hub (USB 3.0)
Thanks!

1803 is what I got, I didn't have to DSDT and this was the only way to get both dGPU and eGPU working. Also wonder if the BIOS version in the MAC(updated by OSX) also affects this. For some reason bootcampdrivers.com manages to allocate the eGPU properly, so what happens about that 32 space addressing as being the root case of code 12? Is bootcampdrivers doing the same thing as DSDT?
Thanks so much @oliverb for jumping on my thread and helping out. I didn't have to do a DSDT!
