Comments

The installation was trouble free, I do experience some startup issues every once in a while where the eGPU isn't correctly detected by the system however either a restart or a manual scan for hardware changes will clear this up. I don't typically plug and unplug my GPU with the system either on or asleep and prefer to just shut down each time.

I came from a TB16 dock where I was having issues with USB device lag (specifically keyboard and mouse), I figured i'd try the USB port on the RTX to run my peripherals however I still see the same issues, devices that do not rely on real-time communication like network and external drives work just fine using that route.

Overall i'm pretty happy with the setup, I get strong desktop performance over my 3 x 1440p displays and a single cable solution for docking and charging.

Which TB3 drivers did you use? I just got the same laptop, and I’m having huge issues with my thunderbolt drivers, code 12 and random BSOD.

This sounds like the exact setup I am looking for.

I travel a lot for work, and I want to get home and be able to do some video editing. So, I think this will work well. Thanks so much!

I have a similar setup.  You mentioned USB peripheral lag.  Any fixes?  I got a Jabra wireless headset that uses a USB dongle and it broke my setup.  I max out at keyboard and mouse.  If I add any other devices the lag makes the system unusable.

 

I think this is an issue with the dell 9380 only being able to handle so much USB bandwidth.  I'm not sure if its fixable.

@ruin, Sadly, no fixes from back when I was evaluating that platform, a few months after I posted this I returned the hardware to Dell and switched to a Precision 3541 with a WD19TB and the eGPU in passthrough from the dock, I don't see any such issues on this platform.

In a few weeks i'm going to start evaluating a newer platform based on the XPS 9310, i'm hoping that Dell have some of their issues worked out.

@ruin Just to give you an update, i've been using the newer 9310 system for about a week or so and it seems they have worked the majority of the issues out.

It's worth noting that I have a pretty decent deployed base of Latitudes from this and the next generation and have seen spotty lag issues with peripherals but I don't have any current open tickets on them so i'm assuming that over time, BIOS and dock updates have made it workable for end users.
