Can't get eGPU (Zotac Amp Box) to work with my MSI GT75 Titan

I have an MSI GT75 Titan. I got a Zotac Amp Box with an RTX 3060 Ti in it.

I plug it into the Thunderbolt port, approve the connection, reinstall Nvidia drivers with clean install checked and both GPUs (internal discrete GPU is a GTX 1080) show up in the list. But from the monitor connected to the eGPU, there's just random colorful lines.

Disabling the GTX 1080 just has it switch to what I assume is the onboard video from the CPU or something. It's Microsoft something or other when I go to Windows' Graphics Settings. Nvidia Control Panel refuses to start. All the while, the RTX 3060 Ti is recognized and listed in Device Manager.

When I restart and go into BIOS, the BIOS screen is mirrored on both the laptop screen and the monitor connected to the eGPU. This is the only time the eGPU works. I couldn't figure out how to disable the internal discrete GPU from the BIOS (even in the advanced settings... I don't think disabling the PCIe x16 port altogether would be a good thing).

As soon as we're out of BIOS and on to Windows, again with the noisy/squiggly colorful lines on the external monitor connected to the eGPU. Sometimes nothing on the screen at all.

Windows only shows one display connected, the laptop display.

I tried a second install of Windows on another removable USB drive. Winds up being same thing. Devices plugged into USB ports of eGPU work. And, as I said, the BIOS will show up on eGPU connected monitor as well as laptop display. Otherwise there's just random noise/lines sometimes, but most of the time nothing.

 

I'm all out of ideas at this point.

One thing I haven't much looked into, is there some special way I should be turning the enclosure on/off? Or a specific time/moment?

 

The Advanced BIOS has a lot of options for everything, including Graphics/PCIE and Thunderbolt. For instance, there's many options about Titan Ridge workarounds and whatnot. Should I be trying any of these?

FWIW, I disabled internal dgpu and even limited it to x4 lane width in the BIOS. That didn't help though.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

@blackbeard_, I'd recommend running DDU to remove all Nvidia graphics drivers. Make sure you open Options in DDU to disable Windows auto-detection and drivers installation too. Restart the computer with eGPU connect then check Device Manager. You should see 3x Microsoft Basic Display Adapter devices showing. This is assuming Intel iGPU is active with Nvidia dGPU, and Nvidia eGPU. Proceed to download the non-laptop version of Nvidia drivers.

I did that, eventually finished and wound up in the same situation. GPU is in Device Manager (and CPU-Z lists it), but can't be used by Windows or any app for anything, including Nvidia apps.

This is from hwinfo. Is I/O Base Address 5 supposed to be at 0? The other internal dgpu has an actual value for it. I disabled extra SATA ports in BIOS, disabled other things in Windows (LAN port, etc) which isn't being used, but no difference.

Interestingly enough, in one of the Windows installs while I was disabling and re-enabling PCIe x16 controller and internal dgpu, now the eGPU (3060 Ti) shows constant error 31. "The I/O device is configured incorrectly or the configuration parameters to the driver are incorrect"

Well, tried the GPU and it was the GPU that was at fault. Guess that's what I get for buying Zotac.

 

It's really weird how the same problem happened in two different desktops. Device appears in Device Manager but remains non-functional, sometimes with Error 43.

 

Enclosure probably was fully functional. I'm RMAing it with Zotac since it came bundled together.

I'll keep this thread updated with how the RMA goes and if they'll send a replacement and if so, how that goes. There isn't much info on this Zotac product online, hopefully this can help encourage or discourage people interested in it depending on how things go now.
