Can't get eGPU to work in Windows Bootcamp

So thank you to everyone that helped me with downgrading my Windows build. I'm now at 18362.30. However, I still am getting error 12 in my device manager, with zero output to my external monitor. I've tried DDU, and installing the latest (September) drivers from bootcampdrivers.com . I have the 2019 Macbook Pro with 2 Thunderbolt ports, and I have an RX 5700XT hooked up to a sonnet breakaway box. The eGPU works perfectly fine in the latest beta build of MacOS Catalina. Thank you!

@jackson_patenaude Not all Macs can work with eGPU in Boot Camp mode through hot-plug. I would recommend trying timed hot-plug by connecting the eGPU to your 2019 13" MacBook Pro as soon as you see the Windows logo with spinning circles.

Yea, I just tried this and it didn't work. Thank you though.

@jackson_patenaude Disable some devices in Device Manager? But that did not seem to be necessary in the following similar builds:

I'm having the same problem. I think perhaps I'll need to go through the "Large Memory" hack process, as every other thing I've tried (using my 2016 non-touchbar 13" MacBook Pro with a Razer Core X and a RX480) has failed: I always get Error 12 no matter what, even running .30

The worst part is, yeah, it works *perfectly* in macOS, but Catalina has basically broken gaming in macOS entirely by removing 32-bit support: most games will never see an update to fix this, sadly.

I'm at a loss, and have a brand-new, $480 AUD paperweight 🙁

I think I just replied to you on reddit, but incase you a different person - you need to be on an earlier version of Windows as per the notification at the top of the forum page. 1903.295 is all good, and I run 1809 on my Macbook.

Yep, that’s me!

Figured I’d post here too for reference: I got past error 12 for a split second disabling PCI-e #9 and #10 after moving to 1903.295, but then it fell over again.

Doing some more research, I think I have to attempt the DSDT override, which I’m giving a crack tonight. What I’m confused about is whether I should follow the steps in Windows (the original DSDT thread) or the linked (in the original thread) macOS one (which has an app and everything) — I feel the former is what makes sense, but BootCamp makes it confusing lol

I believe that you’ll have a much easier time getting the modified DSDT file done via MacOS than Windows, so I recommend doing it there.

Our public repository of eGPU DSDT Overrides contains an appropriate DSDT.aml for the 2016 13" MacBook Pro non TouchBar. Look for and download Apple_2016_late-13in-MacBook-Pro_goalque.zip.

So interestingly, I tried that, and it quite literally busted my Windows boot camp -- stopped it booting altogether, even after removing the USB I was booting off lol

But, writing my own override was simple enough, and it's now working perfectly under Windows 1903 v1 at .295 Smile

Hey everyone. I'm new here. First of all thanks to this forum for all that useful info everywhere.

I just got a 5700 xt and, not surprisingly, the plug and play didn't work. Egpu is connected to a macbook pro 15 inch 2018 with internal amd rx560x. In macOS plug and play works. All is amazing. Now I want to make it work in bootcamp like in OPs problem.

You can see it in the device manager but it is just listed as "Microsoft Basic Display Adapter" and yellow banged (code 31). 

My question would be: "Where do I go from here?" So much info on this site, where to start?
This thread? https://egpu.io/forums/mac-setup/2016-macbook-pro-solving-egpu-error-12-in-windows-10/#post-709
Or that whole shabang here? https://www.bootcampdrivers.com/

Before I start some lenghty installations I wanted to ask for experience on what to try first.

Thank you all Smile

 

Edit: I tried the bootcampdrivers.com solution and now it correctly displays as RX 5700 XT in the device manager BUT it is now yellow banged (code 12). I've heard this one can be hard to fix...

@sebastian_bracht Take a look at the RX 5700 XT + 2018 15" MacBook Pro build by @Mac_editor [link]. His eGPU setup is almost identical to what you're trying to set up.

@itsage Thanks. After reading more, it seems like my best bet for now.
