From Nvidia heaven to AMD nightmare : Solving "No Drivers Installed" problem on a Vega

Hello!

 

I'm having trouble installing an AMD configuration on boot camp.

 

My previous configuration worked sooo well:

- a MacBook Pro 13 2018 touchbar with 4 TB3 ports.

- a KFA2 enclosure with a GeForce GTX 1060 6 Gb

 

With the latest Mac OS Catalina and a Windows 10 at the beginning of 2019, all I had to do was plug the card in just as the little wheel started to turn, and it worked perfectly, without any further adjustments.

 

Today, it's more complicated.

 

I'm trying to run a Razer Core X with a Saphire Radeon Vega 64 8 Gb card on the very same MacBook .

 

1. I reinstalled Windows 10 with the methods found here to get version 295 and block future updates.

2. When I wanted to install the card, I plugged it in at boot time when the little wheel starts to turn, then

3. I used the DDU utility to remove the Windows drivers and then installed the official AMD drivers.

4. During the installation, the progress systematically stops at 96%. I abruptly cut the installation, then

5. I see in the Device Manager that the card is in error 12.

 

I disable the camera (the USB device to which it is attached, USB Composite Device, under the same USB Root Hub that the keyboard) and also the TB3 ports on the right (9DB0)

 

1. I start again: DDU then installation of the official drivers.

2. I am also blocked at 96%. I cut abruptly.

3. Now, the error is "no drivers installed for this device".

 

I see that says half of the information on GPU-Z and in Furmark.

 

Notes :

 

A. I tried Goalque's bootloader (on a FAT32 usb key, modified as agreed for T2 / Catalina systems): the system doesn't see the eGPU at all when I boot Windows with it. (Neither in the little black screen in the boot utility, neither after that in the Device Manager, where the Iris is very sadly alone)

I didn’t need this tweak for the GTX 1060. Do you think it’s still advisable to use it now ? Is there any explaination about the cases where it solves error 12 ?

B. I don't have an external screen, and the previous configuration (Nvidia) worked without needing it.

C. Unigine Valley works on Mac OS too so I tested the eGPU in Mac OS, to be sure the GPU is not a problem here. It works really smooth, just after hot-plugging it.

D. Some people here are talking about pci.sys. What’s the thing about it ?

 

PS : I read many things on this forum, very usefull discussions.. But few people seems to have the "No Drivers" problem. Maybe I did something wrong ?

 

Thank for your help_

Also, I can see in the Device Manager that when I sort by connection, I have a Large Memory with one line (0000004000000000 / 0000007FFFFFFFFF PCI Express Root Complex).

Does this mean that initiating a DSDT override is pointless in this case ?
