2018 Mac Mini i5 3.0 ghz, 16mb ram, 250gb ssd, MacOS 10.15.2 (sucks), AMD RX5700, Core X

I have one monitor plugged in via USB-C to display port. I have another monitor plugged in via the egpu.

I have Windows 10 1809 fully upgraded installed via boot camp. When I plug the egpu with windows already booted up it doesn’t recognize the card (only Microsoft Basic Display Adapter) and gives error 31.

When I shut the computer down and start windows cold with the egpu plugged in and on, on the igpu monitor the loading wheel starts (where you hit option to go to boot camp) then the windows logo flashes (literally) then the monitor cuts off. Nothing after that. The video card spools like its going under load, then stops blowing so much. That’s all I get.

Not sure where to go from here in boot camp. Don’t get me started on how crappy 10.15.2 is. Any advice would be mucho appreciated. Thanks.

Hello, I don't really understand this article.

I am using 2018 15in Macbook Pro Catalina and Razer
Core X with Msi amd RX 5700.

Can you give me the complete instructions for my
system?

My current issue is:
1. Met error 12, don't know what to do, perhaps a
video tutorial can help?

2. Delete and reinstalled Bootcamp, this time when i
plugin my core X, the monitor just blackout, and the
the only way to fix is to reinstall it, reinstalled it server times, any way to fix?

I'm wondering where should I start a thread "all the things about Mac Mini 2018"?

Most of us would use egpu with both windows & macos, so it's shame to scatter things in many threads...

Just bought Razer Core X Chroma today, it works perfectly with my MacBook Pro 16 under Windows! It is weird the non Chroma version doesn't work.

I have a RX580 working on a late 2018 mac mini in Win10 1903. I attempted to upgrade to 5700 XT and have not yet been able to make it work. The RX580 seems to be working fine on the mini with the PCIe x16 and PCIe x4 Controllers disabled in device manager.

I tend to believe that 1903 is bad news for resource management from what I've experienced and read.
I am using the 19.12.3 drivers from the Adreneline 2020 along with the iGPU Intel 630 installed.

I think my next step is going to be to reinstall Win10 @ 1809 if I can and try the 5700 XT again.

I don't need automate-eGPU EFI if I can just plug in my eGPU after it is windows booted, right?

I don't like messing around too much. So no EFI boot loaders no FW updates etc. I have a MBP late 2016 with a dGPU.

Last year I bought the razer core and the Vega 56. I also bought a win 10 OS build 1803.

Now after many attempts I came up with a very simple way to get the eGPU running in boot camp.

1. Install windows 10.
2. Safeboot into windows 10
3. Use DDU to clean and restart drivers
4. Plug in the eGPU (right side)
5. Repeat steps 2 and 3 to remove the drivers windows automatically did upon eGPU plug in
6. Disable PCI ports corresponding to the left side
7. Install drivers from adrenaline

Extra info.
- Never hot plug. And always shut down then boot when switching between OS.
- the dGPU would run in windows without the eGPU plugged in on the internal monitor. With the eGPU plugged in only the external monitor would work, and you wouldn't have the internal monitors working.

All this was find by me because I don't need extra partitions, or USB drives. Additionally I didn't' have to remember to ran .bat files and such when switching OSs etc. I found this convenient because it was the most efficient robust setup without the mess and having restore points if I forget something.

That said... I hate windows update in windows 10. Even if you disable it it automatically comes on after some time. Back in November 2019 windows made a major update without me realising that would happen. It broke my setup. I redid what I did above to no avail. Boot camp would boot up, and the eGPU would run my external monitor but very slow. After trying to restart a few times what happens now is that the eGPU would go into over drive (max fans and such).

So... anyone have any info and ideas? Or will I simply have to follow one of the guides to get large memory allocation and such since it seems to be a resource issue, though it is puzzling since it was fine before (even after updating the Mac OS it had worked without issue), but that windows update really messed it all up

I have a mac mini 3.2GHz 6 core processor + Razer Core x + AMD RX 5700 Ultra. The error code 12 is driving me nuts. I tried downgrading, despite complication, didn't work for me!! I also can't do the cold plugging as it freezes on the Windows loading screen. I tried hot plugin while loading but didn't work for me. I have literally been in front of my screen for the last 8 hours, trying to figure something out. I think the problem with this solution is it talks about MACs in general and ignore the fact that the differences between macs are big. I hope the author could do posts that are more exclusive to Mac minis, MBP, IMacs etc. Please let us know if someone reached a workable solution for Mac Mini?
