[Solved] eGPU error 12 fail after update to Windows 10 1903 or newer (OS Build 18362.329 or newer) inc downgrade pci.sys version solution
My Mac Mini build is iGPU only, using the same setup as you bar OS version.
I'm currently using 2004 19042.421 slow ring and it works with a couple of weird steps, including restarting, unplugging HDMI and fumbling with the monitor controls until the machine restarts and the eGPU kicks in.
I also just realised a typo in my build link. My bad.
1. Agree on the ethernet - it's buggy as hell
2. The power available is 50W difference, although this can be accounted for by the 4 USB (2x 2.0 2x 3.0) ports on the Chroma vs Core X.
I've managed to have it working with the EFI method and the cable dance, I don't like this very much but if there is not an official fix there I go...
@gizzer3010, thanks! sound like too much hassle, I'll skip build 2004 then. I have practically zero issues (apart from HDR, which could be something else) with Windows 10 build 1903 and my setup. And I saw nothing but trouble with any newer build, so I don't feel like wasting several hours again and end up reinstalling 1903...
My system was doing fine with the eGPU on for the last seven months (2018 Mac mini running latest version of macOS Catalina and latest version of bootcamp with Windows 10). Then I had the "brilliant" idea of installing the public beta of Big Sur -in a different container- as i was told it wouldn't mess with my main Catalina and bootcamp systems. Well, turns out that all went well with the installation process, Big Sur runs fine, Catalina also, and then I turn to bootcamp. I launch Starcraft II and the game freezes after 5 min or so. It throws various errors, but the most common BSOD is "memory management". I tried gaming in macOS (particularly Starcraft II) and even though it crashed at the beginning, now it is stable after performing some recommendations from Apple support -mainly disconnecting my Mac for 15 seconds and then plugging it again-.
Iam desperate, I do a lot of gaming, and Windows 10 as you may expect gives the best performance.
What should I do? I think Big Sur updated the firmware in my machine because now I get the classic Mac chime, even though I erased everything and started from scratch installing Catalina to the last version and also Windows 10.
Please give me some pointers, suggestions, recommendations, anything!
Could it be this supposed firmware update? if so, installing future public beta updates of Big Sur in my system patch everything up?
Also, installing DDU could help me in this case?
Thanks in advance.
@jacket, I've tried this 2004 build version with different Macs. While it helps resolving error 12 on 2018 Mac mini and 2019 13-in MacBook Pro, it did not work on the 2019 16-in MacBook Pro (has dGPU). You can try upgrading to this version but make sure to leave the Windows.old folder alone so that you can revert back should the Win10 2004 doesn't work well for your setup.
Thanks for replying. I'm using version 2004 (compilation 19041.450).
So I should download this version from Microsoft website (may 2020 update)? If the link below is wrong, please point me to the correct one.
So based on your experience, this freezing in Windows 10 with my eGPU has nothing to do with me installing the Big Sur public beta in a container? Before doing this I was running the latest version of Windows 10 with my eGPU on without hiccups.
-Im going to erase bootcamp, install version 1903 from scratch as you say.
-Disable Windows updates.
-Run the Radeon Adrenalin 2020 installer
-Test Starcrtaft II.
Please if iam missing some steps feel free to point me in the right direction.
@lothar, My 2018 Mac mini has been running Big Sur Beta since WWDC. There were some issues but they are not Boot Camp eGPU related. Some newer 2004 versions work with the Mac mini + Radeon eGPU but they are not as good as 1903 V1 in my observation.
ok, I'm going to install windows 10 1903 V1. Is the link I provided correct for that build? It does not specify:
I mean this one:
if installing 1903 does not unfreeze my gameplay, should I try DDU?
I always recommend using DDU to remove existing graphics drivers as well as prevent Windows from auto search and install drivers for new devices.
Excuse me for all the questions (english is not my primary language). I clicked the link and selected the first 1903 build for 64bits systems. Whats the meaning of OP?
It finished downloading, I'm going to erase my bootcamp partition and create a new one with the 1903 build.
Hopefully everything will go fine.
