Can't resolve error 12 W/ Razer Core X + RX580 in bootcamp (2017 13" MPB non-touchbar)
Hey everyone, I'm sorry if this is covered many times over, but I have been trying to get my eGPU to work in windows on my MPB for a day or so now and I can't for the life of me get it to work. I want to preface this by saying I am in no way knowledgeable in terms of thunderbolt or the setup of eGPUs in general. This is all new to me.
If I boot into windows, then plug in the coreX, it will usually result in the system recognizing that there's a RX580 there, but it shows error 12 in device manager. If I try and boot with the thing connected, the windows logo displays, but there is no spinning loading animation and the screen starts to glitch and just gets progressively worse until I turn it off. AMD drivers for the RX580 are installed from the AMD website. If I boot from apple_set_os.efi with it connected, it will boot, but still show error 12 if I remember correctly. Depending on how many things I disabled and how the planets happen to be aligned, I got the card to show something on a monitor for a few seconds before the whole system froze and died. (tried this multiple times, never with any success)
What I've tried:
The most obvious thing I've tried is disabling the PCIe root port for the FaceTime HD camera. That didn't affect the situation. Then for the sake of experimentation I tried disabling the one for the WIFI card too, and that didn't seem to work either. Then I tried uninstalling the top option for PCIe (I can't remember what it was called) and then rebooting after the system shat itself and crashed. I hoped it would reconfigure where/how the resources are allocated or something. Still no luck.
I'm not sure at what point I got the card to work for a few seconds but it never worked properly, and as I'm sure you can tell, I have no idea what I am doing anyways. Let me know if I am doing something obviously, stupidly wrong.
I tried it in Windows enterprise LTSB 2016 first then Windows 10 pro for workstations. I figured it would work on that if it works on anything. The setup works beautifully in MacOS, but games perform badly and I want to see if Windows will help or if I need to upgrade my MacBook in order to get decent performance. I tried both thunderbolt ports. I feel like I'm just missing something very obvious.
Thanks for your time!
Please review successful AMD eGPU Win10 builds for your system to see what was needed to overcome error 12:
If you’re adding an egpu to game in windows just grab an Nvidia card, I’ve tried 4 and they were all plug and play, the 2 AMD cards I have tried have been nothing but trouble (error 12).
