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.
@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.
2017 13" MacBook Pro Touch Bar
GTX1060 + AKiTiO Thunder3 + Win10
GTX1070 + Sonnet Breakaway Box + Win10
GTX1070 + Razer Core V1 + Win10
Vega 56 + Razer Core V1 + macOS + Win10
Vega 56 + Mantiz Venus + macOS + W10
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
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
