Few days ago I completed my eGPU setup which consists of the following:

  • 2017 14" Lenovo Yoga 920, i7-8550U, 8GB RAM, 512 SSD
  • ASUS ROG STRIX GeForce GTX 1080 TI
  • ASUS ROG XG Station 2
  • Windows 10 Enterprise 1709

Overall I didn't have any issues enabling the enclosure and the GPU. The only thing I did was:

  1. Install the Intel ThunderBolt driver/software. I couldn't find one on the Lenovo website, so I used the Intel NUC one (Version: 17.2.71.250; 11/20/2017) from here.
  2. Update the XG Station firmware to v25 from here.
  3. Install the latest NVIDIA GPU driver.

The system works well and you don't have to reboot or turn off the laptop when plugging or unplugging the XG Station. In fact I have a small issue with BitLocker. If I turn on the laptop while the XG Station is connected, then the built-in GPU is replaced (turned off) and BitLocker requires me to enter the recovery key. I haven't solved this yet so my workaround is to always connect the XG Station after I sign in to Windows.

Thanks for this info. I'm waiting for a new X1 Yoga to pair up with an external 1080Ti so it's good to hear Lenovo has their s*** together.

Buy open box or new Yoga 920 and probably get back near what you paid when the 2018 x1 yoga models come out...  This is better deal than the $150 savings they had Thanksgiving week for Black Friday.

I am also looking forward to the new 2018 x1 yoga!

This sounds awesome. Where did you find that?

Find what?  Probably won't get any info on the 2018 X1 carbon or X1 Yoga until January 2018...  I was saying you could buy an open box excellent Yoga 920 now for $1001.99 or new for $1099.99 (plus tax) and then sell later for near what you paid if you want to get something now while you wait for 2018 X1.

Hi Ochichka.   I just bought a Yoga 920, and am shopping for an eGPU for flight simulations.  Reading successful and unsuccessful eGPU implementations to decide what eGPU to buy.  Question re: your Thunderbolt driver (step #1 above)....how did you know to install it from the intel web site, and do you think it is safe for all to do so when it doesn't match the version (17.1.64.250 released 2017/09/10) on the Lenovo website?   Perhaps this is the trick needed to solve unsuccessful implementations on the 920.  Your thoughts?  Thanks, Mike 

Update:  disregard this post -- unable to delete -- I've since posted my results an implementation guide thread

To avoid the BitLocker issues on boot, you can disable PCR 2 via Group Policy (Configure TPM platform validation profile for native UEFI firmware configurations). I believe Dell recommends this to solve BitLocker issues with their docks. I'm not sure if you need to fully disable BitLocker to do this or if it can be done with it merely suspended.

EDIT: I can also say that installing the updated Thunderbolt driver intended for the NUC is safe. I installed it on my XPS 15 9550 with no ill effects. I will have to wait and see if it actually solves my USB woes.

Thanks a lot @XCVG. Indeed disabling PCR 2 solved my BitLocker problem. I know it's a bit less secure solution (I'm using the laptop as a business machine too), but the BitLocker PIN compensates it a bit.
