done,  any suggestions? Seemed somehow the eGPU is blocked from accessing that address space

Thanks to this thread, I was able to pinpoint why my Vega 64 with MBP 13in 2019 wasn't working. I confirm that the latest build has issues (aka code12) -- after going back to .295, it's now working fine, Microsoft store is not working though, can't download anything. any fix to that?

Hi.

My 2018 15'' MBP + Razer Corex X with RX480 in bootcamp is working ooookay at 18362.356.

Only issue is to keep internal screen running with dGPU ready to rock at any moment. I am able to keep dGPU online in device management without yellow exclamation mark, but internal screen keeps disappearing from display options and screen is going black in bootup. I am able to get dual screen situation up and running by booting twice: First time boot to Windows without eGPU to make internal screen available again. Then boot to Windows with eGPU plugged in from the getgo. Until next shutdown internal screen keeps running with dGPU acceleration. Next time same issue occurs again.

OS and eGPU acceleration work just fine tho, so I seem to be lucky out of this bunch.

Thanks! this is the only way that worked as the featured update is now pushed out automatically without choice.  Looks like MS is serious in getting these featured updates rolled out there must be something important in them.

I put a 7870XT/LE GPU in a TB3 eGPU enclosure and that works with Windows 10 build 18362.356 and Radeon driver 19.9.2 but a 5700XT gets a Device Manager Code 12 error.

One thing @user99999 and I have in common is the 7870 XT/LE is GCN 1.0 like the M370X.

I uninstalled KB4515384 as suggested in this thread.  The Win10 build is now 18362.239 and the 5700XT is now running fine.

Hi everyone,

I have a 2018 Mac Mini i7 with Gigabyte Aorus GTX 1070. The eGPU won't work if I boot it on Windows after the update. I only get a black screen even though the HDMI cable is attached at the back of the eGPU. I tried to hot-plug the eGPU when Windows is starting but still the black screen appears. The lights of the eGPU is turned off but I heard its running. I tried to boot the Mac again with the eGPU turned off and the HDMI attached to the Mac Mini and it booted fine because the internal gpu took over. I then switched ON my eGPU and the screen froze for about less than a minute. After that, the eGPU was detected and it worked well. I tried to run the Heaven benchmark and it has detected the eGPU as well. When I switched the HDMI cable back to the eGPU, I can't click but I can see the windows desktop. I don't know if I'm the only one to have this kind of problem or I did something wrong. The 1070 drivers are up to date as I recently played the Modern Warfare beta.

FYI: Radeon driver 19.9.3 that was released September 30 did not solve the Code 12 error with Windows .3xx  builds and Radeon 5700 for a Dell Precision 7730 laptop. This laptop has the most recent BIOS, TB3 firmware and drivers.

Runs fine after uninstalling KB4515384.

With three separate updates breaking egpus, not just via bootcamp but altogether, we have to assume that it's a mistake and not an intent.  Does anyone know where to notify them of the issue? Can we hit them with a few notices to underscore that they broke egpus?

I've used the Windows Feedback hub app to report this issue to Microsoft, the following URL should link you to it (I think you may need to be running Windows for this to work):

https://aka.ms/AA65meb

There are 2 other feedbacks complaining about the same issue, if you like you could upvote them too.

https://aka.ms/AA66had

https://aka.ms/AA669l4

I also think that anyone suffering this issue on a laptop with "official" egpu support from their vendor (i.e. Razer, Dell, HP, Lenovo, etc) would be extremely helpful to all of us if they reported this to their corresponding support, since Apple/Microsoft/Nvidia/AMD do not support egpu in boot camp, but the other vendors may be able to report this to Microsoft with more weight than these feedback hub reports.
