XPS with dedicated GPU, nothing is working to get the laptop to detect my eGPU
I have the Node listed as an approved thunderbolt device, but I cannot find anything mentioning the existence of the GPU inside of it in the device manager. I've disabled/uninstalled my 1050Ti dGPU and I've DDU'ed in Safe Mode and attempted to install the 10XX drivers, but it says that no compatible device has been found. I attempted all of this again on a fresh Windows 10 install and still no luck. I'm at a loss for what else there is to do to get it to detect the GPU inside of the enclosure. I should note that I've previously used my friend's Aorus GTX 1080 gaming box on this device with no issue, which is why I felt like maybe a reset would fix these problems initially.
I have a 9575 and had an issue similar to this. It was because my thunderbolt driver was out of date. Do you have the thunderbolt drivers installed? Mine is like this intel thunderbolt driver. Yours is probably something similar and should be listed on their drivers page for your service tag.
Also make sure you've got it in the right port. The 9575 only has thunderbolt and 4 lanes of PCIE on the left 2 ports. The right 2 are just USBc.
Late to the party, but you most likely need to update your thunderbolt firmware AND the thunderbolt driver/controller. Once that is done, your computer will see the eGPU and you can install the corresponding display drivers.
I've got egpus working on the 9550 and 9570, and it was the firmware and drivers that got in the way of it being a PnP egpu setup.
