Running the GTX 1070 with a 450W power supply on the PCB of a Thunder3 at 32Gbps which can be confirmed by GPU-Z:

.

The PSU powers both the GPU and the Thunder3 using the barrel plug mod. Pictures of the set up:

 32Gbps-TB3 confirmed:

 

Steps I had to undertake to get this working:

  1. Updated to the latest Thunderbolt driver/firmware (NVM 15 for me) and to the latest BIOS.

  2. Plugged in the eGPU - after Windows detected the 1070 and made me restart, I was shown the  infamous error 43 in the device manager (presumably due to a driver conflict between the 960M dGPU and the 1070).

  3. Downloaded and extracted the latest DDU. Booted into Safe Mode, wiped the Nvidia display drivers and disabled Windows from downloading display drivers (latest version of DDU does this automatically)

  4. Downloaded and installed the latest 1070 driver from the Geforce website. The installation detected both cards and proceeded without any issues.

Haven't run any benchmarks as there are an abundance of them elsewhere. Haven't tried gaming on the internal screen either. Games run very well on the external monitor - no complaints there. 

However there are a few issues that affect day to day operation that may or may not be limited to my device:

  • Gigabyte's XTREME Engine does not detect the card which makes it impossible to turn off the GPU LEDs or switch to OC mode
  • Plugging the eGPU in while Windows is running causes the computer to lag. This is resolved by restarting the computer
  • (the most annoying) Shutting down the computer with the eGPU plugged in causes black screens on boot when the eGPU is not plugged in. This is resolved by force shutting down and restarting the computer THREE times or plugging the eGPU back in during the black screen. This can be prevented by unplugging the eGPU before shutting down

The black screen on boot could be caused by incompatibilities with the BIOS and a second GPU. Does anyone else have this issue?

If you intend on connecting and disconnecting the eGPU several times a day, it would be wise to invest in an SSD for all the restarting.

Nice work there. Sure, the video card is connecting at x4 3.0 link speed but we need CUDA-Z performance results to see what the Thunderbolt channel is doing. CUDA-Z bandwidth results are typically > 2200MiB/s for TB3 and ~1400MiB/s for TB2. We've seen a few systems run their TB controller at half PCIe speed with this being the litmus test.

I thought GPU-Z verifies the connection speed when you run the render test? I tried launching CUDA-Z but it displays the following message:

Disable your dGPU, then connect your eGPU. CUDA-Z can't properly handle multiple installed and active Nvidia cards. Had the same issue yesterday with my K2100M dGPU and GTX 970 eGPU.

Aye, put me on the implementations list. Also, do you know any place in Melbourne that will cut my Thunder3 chassis? Wouldn't mind spending AUD50 instead of bending it.

Some TB3 systems report significantly lower host to device CUDA performance but device to host is close to Sonnet's advertised 2750MB/s (I suppose reading speed). Is this due to dual core CPU?

Nicely done. You are added, near the very top. Good to know the UX501VX has full speed TB3 ports. An attractive system.

Can't advise about cutting places other than the usual yellowpages/google search for "laser cutting". Or go the DIY opening-chassis approach. The extra chassis length there protecting the back of your video card if it doesn't have a backplate.

Have you tried to connect G501VW to AKiTiO Node yet ? I've planned to buy Node but not sure that my laptop will work with this.

@bossboonpt, the first pic is of a G501VX. The thread is titled UX501VX because it shares the same internals as the G501VX.
