[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
Hi, I saw this threat highlighted in the main page. Is this only for MacBookPro users? I'm using a Dell Laptop with Windows 10 1909 and eGPU with AMD RX without issues at all.
Dell Inspiron 14 FHD 3442 mod with 3543 i5-5200U motherboard. 8GB RAM. eGPU PCE164P V008 MSI RX550 4GB OC. PSU 500W.
Sorry for beeing noobish but after following multiple guides, installs and try outs I still cant´t get my setup to work in Bootcamp.
Is there a failproof way of getting a Macbook Pro 13 2019 with two TB3 ports to get a running eGPU in Bootcamp?
- Macbook Pro 13, 2019, I5, 8GB, Touchbar, Intel Iris GPU and two TB3 ports on the left side
- Asus XG station pro with a Asus RX 580
- MacOs Catalina 10.15.2 and Windows 10 19H1 (Build 18362.30)
Merry Christmas and thank you!
Replacing the pci.sys file works for my setup. Thank you so much!
Will we need to grant TrustedInstaller access permissions to the pci.sys file again in order to update windows in the future?
I'm sad to report the fix (Using the pci.sys provided by @Shiraz) was not successful in my case.
EDIT: After doing a clean reinstall of windows this comment no longer applies, I suspect it was a messy install from many failed attempts causing issues. This fix is working for me, alight I cant boot windows with the eGPU connected, it must be connected after startup.
Update regarding the pci.sys fix by mentioned here https://egpu.io/forums/pc-setup/egpu-fail-after-update-to-windows-19-03/
Initially after applying the fix error 12 was fixed and the AMD drivers detected an external GPU (Driver version 19.10.2). They also detected the display connected to the GPU, however the display remained a black screen. After restarting with the GPU connected, the screen remained black. Interestingly remote desktop connection was not possible, suggesting startup was failing as before.
I attempted uninstalling the AMD drivers, after this device manager reported error 35 (Bios does not know how to setup this device). After 2-3 re-hot plugs of the egpu, error 12 had returned. Attempting to reinstall AMD drivers at there the error 35 or error 12 point resulted in the AMD drivers saying no hardware was detected.
So Iv not lost the driver install, and cant get it back. This could be unique to the fact I'm using Windows Education Edition or not. However I have to conclude the pci.sys fix does partly work, but not fully in my case.
curious on pci.sys fix so just did an upgrade to 1909 which gave me error 12 by no surprise...
but....wow, pci.sys fix works. as soon as I reboot after replace the pci.sys, all back to normal.
Thanks a lot for the tips, all
