Did anyone had any luck using Radeon RX 5700 XT with a Windows 10 version newer than 1903.295?

@precision01 This issue affects the host computer rather than a particular graphics card. I believe all Macs with Apple T2 Chip have this issue in Boot Camp. The pci.sys file replacement from Win10 1903 V1 ISO is the only workaround if you need to run latest Windows version.

Interesting, @itsage. Do we just have to replace pci.sys from any Windows 10 version with the one from Windows 10 1903.295? If it is not that simple, are there instructions for that workaround here on eGPU.io?

I have the same issue with windows 1803 since the last and final update in December. 

As windows 1803 will not be updated again, what would you recommend?

Build: Mac mini 2018 + Razer Core x +  Readon Rx 5700 (NOT XT) + Catalina 10.15.2 + Windows 10 1909   .535 

Tricks tried to fix Error 12: 

- pci.sys file swap 

- efi boot file (later figured it is irrelevant to mini)

- Downgrading windows 10 to .295 (didn’t work for me + People mentioned steam and Xbox don’t work on older windows versions) 

- Hot plug (card works but error 12 + later realized doesn’t work for AMD cards) + cold plug (Windows 10 doesn’t bolt beyond the logo) 

- Changing thunderbolt slot (tried all 4 of them with no success) 

- Disabling Pci Root and/or disabling iGPU. 
- reinstalling windows 1903 v1 (doesn’t boot beyond logo with eGPU connected) 

- Contacted AMD, Apple and Microsoft ( non wanted to take the blame especially AMD and Microsoft) 

Lets plz keep the topic for mac mino only because other fixes DONT work for mini. And EACH mac type and version is different. 

if someone tried something else, please share!

Have been on the .295 update since this first started to occur (and works almost perfectly). Just wanted to check the progress on the current state with AMD cards. Doesn't seem to have evolved to the extremes. But the pci.sys provided by @florin_samareanu sounded interesting. Seems that it still doesn't work for everyone though (which is heartbreaking). But I might give it a go if I have time this week on my MBP 15" touchbar 2016 + Vega56.

It seems that the Nvidia eGPU solutions still works best in bootcamp. I have a hard time believing that the teams at Nvidia is working/prioritizing to get specific eGPU solutions to work. It's more likely an effect of how their cards operate in general, being more efficient and not as highly resource dependent as AMD cards that their cards still works after recent MS updates. 

Is it confirmed what happened with the updates from .295 going forward? Why specifically that update works and not .329 . Right now it seems that most people (including me) by trial and error tries version to see what works, and stick with it without actually figuring out what caused it in the first place. We can try to *poke* MS and AMD for fixes (which we definitely should). But i think we might need more solutions like @florin_samareanu provided (even tho it was not a mac). 

Disclaimer: even though I am a computer science student (currently studying). I am by no means a hacker and programming isn't my favorite subject. I'm looking at .329 patchnotes from the 30th of August: https://support.microsoft.com/en-us/help/4512941/windows-10-update-kb4512941

Trying to see what changes could have caused it. Has anyone done more research within these patchnotes and come up with a theory previously? It's also likley that some changes were not included in this patchnote MS part.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Downgrading didn't work for me. I hate being forced to use this piece of crap OS for gaming. How do you fix? I'm running Windows 1903.

My windows 1903 version 18362.295 was updated to 18362.592 yesterday.

This is what I did to enable egpu.

  1. Disable PCIE Root port#3 -9DBA
  2. Shut down windows
  3. Power cycles egpu (turn off at least 30 secs)
  4. Turn on egpu, connect TB3 cable to laptop, (Turn on laptop)
  5. Use Refind to enable internal graphics

Tested on MBP 13 2018 i5 Touchbar with external display both with Aorus Gaming Box RX580 and Mantiz Venus. 

MacOs Mojave 10.14.6

AMD ver 19.12.3

MBP 2018 13" i5 512GB Touch Bar (MR9R2)
Aorus Gaming Box RX580
Mantiz Venus, Red Devil 5700XT
