EGPU only works on 1 out of the 2 Thunderbolt ports on DELL XPS 7390
DELL XPS 7390 (has two Thunderbolt 3 ports)
Gigabyte GeForce RTX 2070 8GB Windforce OC Triple Fan
Windows 10 Pro 1909 (latest updates installed)
Hello all! The EGPU setup I have only works on the left, rear most Thunderbolt Port. If I plug the EGPU into the other available Thunderbolt port (the one right next to the working port) I get a "This device cannot find enough free resources that it can use (code 12)" error.
Does any one know what could be the issue? Why would one port work and the other would not? Thank you in advance everyone.
@nosnim, Run DDU to remove graphics drivers and disassociate the PCIe resource allocation to that TB3 port. Once you do that, you can set the eGPU up with the other port. You can also try upgrading the system to Windows 10 May 2020 version.
