Installation steps

  1. Opened up enclosure, connected GPU with riser cable and power extension cable
  2. Downloaded and installed Nvidia drivers
  3. Reboot

When rebooting with eGPU attached BIOS complains about incompatible USB-C device.

Comment
I tried updating the TB3 firmware with the utility provided by Gigabyte but it cannot detect the device. Is this possibly caused by using a different GPU?

Soon I will add my system & eGPU details or a build link to this my signature to give context to my posts

@jc2222 , thank you got your submission. The picture links are broken so cannot see your CUDA-Z H2D values.  Did you want to repost them?

@theitsage did confirm your XPS 9365 has a 4-lane TB3 controller here so your upper limit would be 32Gbps-TB3 bandwidth.

After reading some more and downloading the correct firmware, Host to Device is now 1598 MiB/s:
cuda_z_2
My next steps are replacing the GPU fan and looking into a custom enclosure.

The cable I have is (I'm assuming) the OEM 0.5m cable provided with the Aorus Gaming box and it does have a 3 printed on each end, indicative it's a 40Gbps cable.

All of the above benchmarks have been with the internal screen and I don't know how much that affects the performance.

Update: why bandwidth is lower-than-expected

The lower-than-expected bandwidth numbers are due to the Dell XPS 9365 running a 2GT/s rather than 4GT/s OPI here.
