Blackmagic EGPU and Bootcamp with a Mac Mini 2018

Been hearing many things about this combo. First that it wasn't supported at all. Then supported in Windows Insider. Then heard that the bootcampdrivers mod was required. Then heard it was only required with Macs that already have dedicated AMD GPU, etc.

Well, my Mac Mini doesn't have a dedicated AMD card, so curious if I really do need the bootcampdrivers. I'd rather not void my warranty if I don't have to. I definitely need something done, because currently Windows Bootcamp recognizes the Blackmagic EGPU, but not as a GPU, and can't find the drivers it needs. I'd really like to try and get it working in Windows if possible. Mainly got it, because it works with my classic Thunderbolt Display. Whereas the other eGPU solutions need a little modding to get the Thunderbolt display working with the Display ports.

I don't think you can void warranties by installing software.

Mac mini (2018), Mac Pro (Early 2008), MacBook Pro (Retina, 15-inch, Mid 2015), GA-Z170X-Gaming 7, Sapphire Pulse Radeon RX 580 8GB GDDR5, Sonnet Echo Express III-D, Trebleet Thunderbolt 3 to NVMe M.2 case

The Bootcampdrivers site says it will. Warms about it on the main page. That's why if there's an alternative, I'd rather go that route.

Like has anyone tried installing the AMD drivers from the AMD site to see if that might get it working?

@c-films Many people/companies are playing it safe because of lawyers. They wanted to make sure it's explicitly written that if you break anything you can't blame it on anyone else but yourself. You will be fine with installing the modified Radeon drivers from bootcampdrivers.com.

@c-films

I'm also interested on this.

Please share your experiences if you are able to successfully run the Blackmagic EGPU on your Mac Mini bootcamp.

Do you have any guide that you are following?

Your post inspired me to test again after a frustrated attempt last year.

I finally got my Blackmagic eGPU to work on my Mac Mini 2018 while on bootcamp.

Here are the steps that I took:

1. Disconnected the eGPU from my MacMini

2. Installed Windows 10 1909 through Bootcamp

3. Rebooted on Windows

4. Connected the eGPU, but with my monitor still connected directly to the Mac Mini. (not the eGPU)

5. Downloaded the latest driver on bootcampdrivers.com (2020 blue enterprise edition)

6. Ran the AMD Setup and installed the driver. Got a Code 12 Error.

6. Removed the external SSD. Turned Off the computer.

7. Connected my Mac Mini to the eGPU, and the eGPU to the Monitor.

8. Turned On the Mac Mini. Got a black screen, and it looked like the computer rebooted a few times in a row.

9. Nothing was working, so I turned off and on the computer a few times. When I was about to give up, I saw the windows log in screen. The eGPU was installed correctly and working as expected.

Thanks for resurfacing this topic. Good Luck and have fun! =)

@meadmaker, I have no idea if you’re still following this thread. I’m trying this exact setup now, and I’m at stage 8. I can see through Remote Desktop that the eGPU is recognized and installed correctly, but my Apple Thunderbolt Display is black.

Can you tell me exactly which ports you’re using in the two units? Thanks.

Hi @monsieur_walsh 

I was not using an Apple Thunderbolt Display, but a Samsung monitor through a DP connection. 

I used the 1st and 3rd thunderbolt slots on my Mac Mini, with the eGPU on 1st, the SSD on 3rd and the display connected through the HDMI port with a HDMI > DP adapter. I don’t remember which exact slot I had on the eGPU, but I believe it was the one at the top. 

After I got to step 8, I just removed the HDMI cable and connected the eGPU to the monitor with a Thunderbolt > Distplay Port adapter.

I hope it helps. I had to hard turn-off and on my Mac Mini several times, almost losing all hope, before it worked. After I got it to work the first time things got smoother though...

@meadmaker, thanks for the reply. I can see there are some reports of booting with HDMI and then changing output afterwards that seem to work. I tried today to hook it up to an HDMI monitor, but as soon as the eGPU was added to the equation, the HDMI image went bonkers. Will need to do more testing. Thanks for taking the time.
