2018 14" Lenovo Thinkpad X1 Carbon + [email protected] (HP Omen Accelerator) + Win10 [paulpaulson] // doesn't work well, don't do this)
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.

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)
Installation steps (what did you do to get it all going?)
I followed the manufacturer's installation guide here:
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.
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.
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.[url= http://www.userbenchmark.com/UserRun/9582049]UserBenchmarks: Game 71%, Desk 101%, Work 62%[/url] CPU: [url= http://cpu.userbenchmark.com/SpeedTest/353957/IntelR-CoreTM-i7-8650U-CPU---190GHz]Intel Core i7-8650U[/url] - [b]73.2%[/b] GPU: [url= http://gpu.userbenchmark.com/Nvidia-GTX-1060-6GB/Rating/3639]Nvidia GTX 1060-6GB[/url] - [b]71.9%[/b] SSD: [url= http://ssd.userbenchmark.com/SpeedTest/413203/PM981-NVMe-Samsung-1024GB]Samsung PM981 NVMe PCIe M.2 1TB[/url] - [b]221.2%[/b] RAM: [url= http://ram.userbenchmark.com/SpeedTest/265336/Micron-MT52L1G32D4PG-093-2x8GB]Micron MT52L1G32D4PG-093 2x8GB[/url] - [b]71.4%[/b] MBD: [url= http://www.userbenchmark.com/System/Lenovo-20KH002HUS/80031]Lenovo 20KH002HUS[/url]
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?
