Hi all,

I have a Mac mini 2018 i7 with a thunderbolt eGPU amd vega 64. After my windows update, the egpu is showed in Device Manager with the  yellow exclamation point (error 12). I installed the latest amd drivers but when I restart the Mac mini i need to connect the HDMI cable directly to Mac mini to see something and the egpu stay with exclamation point. I tried to install the May windows version from zero and the issue wasn't resolved. Now I installed again the windows version october 2018 and it work fine again. However I cant use xbox game pass with this version because a latest windows update is needed. any idea to solve this issue ?

thank you.

maybe try removing the windows drivers with DDU, update Windows to 1903 and then give it a go again? Also, are you sure 1903 is detecting the thunderbolt drivers properly? I upgraded to 1903, and then switched to the DCH drivers with no problems. Lastly, would you be able to give us a breakdown of the steps you use to set up your bootcamp partition on your Mac Mini? (including the boot camp drivers I'm assuming)

And just a caveat, I never do any upgrades to the OS and drivers with the eGPU installed, I always boot up Windows by itself just to avoid any issues.

Current build: XPS 15" 9500 + Mantiz Venus MZ-02 + Silverstone SX700-LPT + Noctua NF-A14 + GeForce RTX 3070 FE
Previous build: 2017 15" MacBook Pro + Mantiz Venus MZ-02 + Silverstone SX700-LPT + Noctua NF-A14 + Gigabyte GeForce GTX 1070 G1 Gaming 8G (rev. 1.0)

Hi,thank you for your reply.
I used this drive : https://www.amd.com/en/support/graphics/radeon-rx-vega-series/radeon-rx-vega-series/radeon-rx-vega-64
I also installed windows 19.03  with a clear installation but this not solved my problem.
I follow this steps:
1- Start mac with with the EGPU off, then when windows is started I turn on the egpu and restart the machine.
2- at startup I see the monitor blinking so I put off the mac with power button unplug the hdmi cable and turn on the mac again with the display port cable only and the egpu plugged in. 

With this steps the windows previusly version the egpu is correctly detected with the 19.03 not :(.

what mean dhc driver ?

Which macOS version are you using? If you install Catalina Beta, there's Boot Screen support through the eGPU so that you don't have to switch back and forth between HDMI port from Mac mini to DisplayPort from eGPU. That way your boot up procedure is also simpler, always have the eGPU connected and powered ON prior to boot. I'm using my 2018 Mac mini + Radeon VII exactly this way and there's no error 12 issue with the latest Windows 10 1903.

I can confirm that if you install the latest "Optional" update from Microsoft for windows that it disables eGPU... without update, no problem... as soona s you run the update it kills it. I will be testing it again tonight but there is something fishy going on with a recent optional update. My recent build with my 2019 MBP worked great... ran the optional install and now error 12... no amount of DDU repairs it...

I too ran into an issue with the latest update. Had everything working on my 2018 Mac mini + Akitio Node Vega 64 eGPU and then update... stopped working. Frustrating to say the least.

@daniele_pugliese, @ttamnogard, and @visvism Can you run winver in the Taskbar search box to get the OS Build number? I'm collecting information to see whether this new Windows 10 build is causing more headache. I updated my 2016 15" MacBook Pro to 18362.329 tonight and setting up eGPU becomes harder.

Exact same system as above and eGPU now shows Code 12 error when it was working perfectly fine before.

I'm on latest Mojave 10.14.6
