Help - Razer Core X, AMD RX 580, 13' Late 2017 non touch bar Macbook Pro
Hi all, First i would like to thank this community for all the work done in helping to get EGPU's to run on windows on bootcamp macs. Its impressive and i thank you. I have spent the last two days trying to get my set up to work which no luck. I reinstalled a fresh version of windows via bootcamp to version 1903 OS Build 18362.356. I followed the the bootcamp drivers instructions to a T, but still end up with error 207 and yellow banger. I can not get past this point. Does anyone have any tips or suggestions in getting past this error or fixing it. I am not trying to play any hardcore games, but just use the EGPU to set up 3 external monitors so i can work from home during these crazy times which we currently are living through. Any help will be greatly appreciated. I have attached pictures of my errors below
There are 28 bootcamp 2017 13-inch MacBook builds with AMD TB3 eGPUs available to help you along:
@nando4, Thanks Nando4, None of them worked. I tried the code 12 fix on the front page and am having trouble with that. Do you know where i can find these files being reference in the instructions? Any help would be greatly appreciated.
Temporary Fix [by @bas_timer]
A quick analysis shows that in `pci.sys`, a function called "PciOverrideBridgeRequirements" got changed between .1 and .329 to add 2 additional override cases from the initial build of pci.sys. There does not seem to be a registry change to bypass this, but perhaps this can be overridden from ACPI: that's a slightly later concern I might look into, it does seem to act on a resource requirement value. For now, downgrading system32\drivers\pci.sys to the version shipped with the initial 18362.1/.10 ISO (take ownership, rename, replace) works fine, but it might be this'll need to be put back to allow future CUs editing this file to be installed. Perhaps as a workaround references to pci.sys in the registry could be renamed to, say, pci2.sys as well, but I'm not certain about this...
- Open install.wim with 7-Zip
- Mount the Image and then extract the following file
- After updating Windows to 1903/1909 boot from an "Emergency" USB-Drive and replace Windows\System32\drivers\pci.sys with the extract one.
- Reboot and your AMD eGPU will working.
