External Monitor - LG 27UK850 27" 4K UHD IPS Monitor with HDR10


eGPU hardware

Razer Core X Chroma

ZOTAC Gaming GeForce RTX 2080 Ti 11GB

Installation steps

Still working out a few kinks with this setup, however, @prasys does provide a starting point with the following steps:

1. Be sure to update all the frimware via Lenovo Vantage-  this includes the BIOS & TB3 Frimware
2. Go to BIOS and disable Thunderbolt security - else it gets all cranky 
3. Uninstall drivers using  DDU . It's important that you do not let the computer to use the stock Lenovo drivers , otherwise you'll have a lot of issues when unplugging or swapping the graphics. 
4. Download Latest  NVIDIA Driver  (Pick the Mobile version) and have it installed 
5. Reboot!


Benchmarks 

Will add benchmark pictures when I have the chance and after I've work out the kinks in this setup. 

I will say that as of right now, I've been able to play Doom (2016), Far Cry 5, Arma 3 at a solid and reliable 60 FPS.


This last image demonstrates better performance when using the included USB-C cable from Razer.


Comments 

Prior to assembling this build, I had an old desktop PC, built in 2013, that currently has a 3rd gen i7, 16 GB DDR3 RAM, and a GTX 1070 as well as a SurfaceBook 2 15" with 16 GB DDR4 RAM and GTX 1060. This was great for for a while in college as an engineer student, I would be able to perform heavy Solidworks builds on my desktop and light building on the SurfaceBook. Furthermore I could continue using the SurfaceBook in tablet mode to take notes during class.

 

I switched over in order to better suit my current needs as I tend to travel more frequently for work. This build allows me to continue to enjoy an amazing gaming experience with the RTX 2080 Ti, especially at 4K, yet also keep my work assets accessible on the same system. The dGPU is still good enough for daily tasks, and and coupled with the 9th gen CPU and FHD HDR display provides excellent battery life.

@gideon_brillantes , thank  you for your build. Do note that your CUDA-Z host-to-device (H2D) bandwidth looks more like a downgraded 16Gbps TB2 link:

https://egpu.io/builds/#perf

Same link explains things to check to get full 32Gbps-TB3 performance:

32Gbps-TB3: to achieve ~2254MiB/s H2D (Nvidia) or ~2550MB/s (AMD) requires the correct TB3 enclosure firmware, a 40Gbps TB3 cable , NO additional active TB3 enclosure ports and a x4 3.0 host PCIe port (not x4 2.0). U-CPU systems must be in OPI 4GT/s.

@nando4 Looking at the photos I don't think Gideon is using the enclosed 70cm cable that comes with the Core X Chroma (I know that cable is a lot shorter than I thought it was going to be - so that could be the issue.

@Gideon how is the noise from the Gen 2. I received one last week but it's going back as the fans were too noisy and far too active even when I wasn't doing anything. 

I've replaced it with a Razer Blade Stealth as I worked out I could cope without the CPU grunt. I build report will follow later

 

 

 

2019 Razer Blade Stealth (16gb, replacement 1tb NVme, MX150)
Razer Core X Chroma (replacement SF750 PSU, Noctua NF-S12A FLX Fan)
EVGA 1080 to be replaced by Gigabyte 2080 TI Windforce OC once it arrives

Good point about the included USB-C cable for the Core X. I'll try using that one instead and return the results once I've changed it out. 

 

Fan noise is minimal and only engages when I'm playing a game. Even then it isn't too loud.

Thinking I should update this thread:

Since the last post, I've swapped the USB-C I was working with initially that was giving me 16 GB data transfer rates and now seeing those improved rates as shown in the graphics in the OP.

 

Only problems I'm still seeing at this time is inconsistent fps in some games. Recently began playing the new COD MW and have run into issues with the graphics glitching out in some scenes or >40 fps in one game then <30 fps in the next (Ultra settings at 4K). Totally could be the fault of the installation files and will probably look into reinstalling the game entirely (scan and repair reports no issues). Outer Worlds with the same settings was  gimmicky at first but has improved since. 

 

As some have reported in other forums/threads/sites, the use of the eGPU will most likely perform at one tier lower than what it is capable (i.e. my 2080 Ti eGPU demonstrates the performance of a normal 2080 GPU) so I'm maintaining relatively low standards for the setup I have going through the eGPU.

Hey,  how is it going on now? It might be great if you could add the thermal pad on VRM since i recall that most of the laptop doesn't have it except the razer blade 15..

Have you observed any issues with USB peripherals connected to the Chroma no longer working on start-up and requiring a restart?

Awesome ! Nice setup. I am wondering - do you have issues with booting up the Laptop with TB3 plugged in. Often times , it gets stuck in a boot loop. I am not sure if Lenovo decided to fix it in Gen2

I only have my Razer keyboard connected as a peripheral to the Razer Core X Chroma. So far it hasn't demonstrated the issue you mentioned.

Thanks! The only time I have issues with the bootloop is sometimes when I restart the computer (not a hard shutdown). I usually just keep the laptop open when I have it plugged to the Core. When I turn the X1E on from completely off, it never runs into the bootloop issue.

Looks like Lenovo did not fix it in Gen 2 either. Do you have frame rate drop issue with two monitors (i.e laptop internal + external). I realised that I need to toggle Intel HD on/off , otherwise there would be huge frame drops if I use two monitors

I only disabled the 1650 and it's been working fine since then. I wouldn't recommend disabling both the Intel GPU and 1650 (definitely caused problems) but otherwise with the 1650 off I don't have issues with framerate. Although I have to say the 2080 Ti does have occasional hiccups for some reason (inconsistencies in FPS in game).
