I don't want to suggest this as a build guide, but I want to share my experience to either get tips or to caution people that this combination is tricky. 

 

System specs (model inc screen size, CPU, iGPU, dGPU, operating system)

●  Processor: 8th Generation Intel® Core™ i7-8650U Processor with vPro® (1.90GHz, up to 4.20GHz with Turbo Boost, 8MB Cache)

●  Operating System: Windows 10 Pro 64

●  Display Type: 14.0" HDR WQHD (2560 x 1440) IPS glossy with Dolby Vision, 500 nits

●  Memory: 16 GB LPDDR3 2133MHz (Onboard)

●  Hard Drive: 1 TB Solid State Drive, PCIe-NVME OPAL2.0 M.2

 

eGPU hardware (eGPU enclosure, video card, any third-party TB3 cable, any custom mods)
OMEN by HP GA1 Accelerator
MSI GAMING GeForce GTX 1060 6GB GDDR5 DirectX 12 VR Ready (GeForce GTX 1060 GAMING X 6G)

 
All of this is being run on two 1440p 25 inch monitors and a Lenovo Explorer WMR headset.

 

Installation steps (what did you do to get it all going?)

I followed the manufacturer's installation guide here:

https://support.hp.com/us-en/document/c05573720

I encountered problems including:

1) Plugging the TB3 cable in to my laptop leads to BSOD about 1/4 of the time. This happens even on a clean boot. 

2) Plugging the TB3 cable in does not lead to the eGPU being recognized about 1/2 of the time. Charging always works.

3) USB ports on the hub function poorly - Logitech integrated receivers do not work, mice and keyboards stutter, VR headsets are picked up half of the time.

I've uninstalled and reinstalled many versions of the following:
laptop motherboard firmware
Omen accelerator firmware
TB driver
GPU driver
Omen accelerator application

When it works, it is great. Quite (Omen fan is a bit noisier than I'd like, but still much quieter than the laptop), fast, etc. 

However, random BSOD are bad and so I can't recommend this combination. 

Update: I've made a few changes that seem to have improved things:

1) I enabled the BIOS setting BIOS Assisted TB3 mode (for prior to Windows 10 1709). (: Based on the reddit thread here https://www.reddit.com/r/eGPU/comments/86ftcf/lenovo_x1_carbon_6_with_aorus_1070_gaming_box/) I haven't suffered a BSOD since I made that change, but we'll see as it has only been a day.

2) I've also started powering off and on the eGPU before plugging in the TB3 cable, which helps the recognition issue.

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

Update2: 

I'm getting in the 57th percentile of performance among people with a GTX 1060 6GB in the userbenchmark.com benchmarks. I'm happy about that - I was expecting a penalty given I'm running the card externally but I'm not seeing that at least in those benchmarks.

Update 3:

In terms of getting the device to work:

- BSOD issue fixed: I changed a BIOS setting to enable BIOS assisted thunderbolt, based off of a Reddit post. That seemed to have fixed the BSOD issue.

- USB Hub still doesn't work: Still works poorly. I use it for my printer only, where it works fine as the lag issues don't matter.

- Recognition of computer improved, still bad: Things have gotten better here, unsure if it is due to the above or driver updates. I'd say it is now a problem 20% of the time. If the device isn't recognized, I can deauthorize it and then reauthorize it from the TB3 control panel which sometimes fixes it, if not restarting my computer usually fixes it.

I also modded the device. Pics:  https://imgur.com/a/dmK9MbO

I removed the stand, the front Omen logo, and all of the lights. This is reversible and took about 20 minutes with a screwdriver. This makes the device much more compact and seems like it will improve ventilation. I took off about a pound of junk in total.

Could you do a Unigine Valley benchmark, type Extreme on 2560 x 1440?
