Https://us.msi.com/Laptop/gs30-shadow-with-gaming-dock-intel-iris-pro-5200.html

System specs:
i7-4870hq (thermal compound replaced by me because of overheating problem{it still overheats})
Iris pro 5200 (disabled because of optimus compatibility issues)
2x128gb sata m.2 ssd (upgraded to 2x 1tb ssds because i use it on the go)
16gb ram (2x 8gb sticks)

eGPU hardware: Manufacturer included "Gaming Dock" Connects via Proprietary connector (PCIEe 16x)
Gpu: 1070 gaming z (Originally bundled with a 970 on release)
Storage:   12tb 3.5 inch hdd originally had no hard drive, but included 3.5 inch mounting hardware, and doesnt have included 2.5 inch mounting holes
Other Ports: 4xusb 3.0 1x ethernet, separate headphone and microphone jack, standard pc power and proprietary connector for laptop

Personal additions: External cooler, sucking style > https://www.amazon.com/LC05-Cooling-Auto-Temp-Detection-Compatible/dp/B01NACVLWM?th=1
 

Hardware pictures: 

Linus did a great video on it:

 

Installation steps: Plug and play, but...
If you dont want to use the internal screen while it is on the dock, Do not upgrade the bios, there are compatibility issues with nvidia optimus
If you do, you do need to upgrade the bios, available on manufacturers website, however you cant go back (if someone has the original bios, message me, i want it back)
If you upgraded bios and want the compatibility issues to go away, turn boot mode to uefi mode (without csm) and the integrated gpu will be disabled in docked mode and enabled without

Benchmarks :
My 1070 overclocked really well, +105 core +550 memory, and I had to turn down the cpu voltage and power (-.075v, -1.75W) to prevent throttling (it didnt work)

Comments: 

I got it on amazon for 1.1k no gpu included, and added the 1070, because I needed a laptop, i wanted to game, and i could only make one purchase (gpu acquired later)

I needed a 15" or smaller laptop for school, and wanted a desktop at home, and really didn't want two separate systems. 
This was my first gaming build, and the computer was made around Christmas 2017.

The integrated Gpu is really bad for gaming, dont purchase this if you plan to game on the go.

The gpu is connected with full pcie 3.0x16, so there is no bandwidth throttling, but the cpu is weak by current standards, and it is not hot pluggable, you Need to shutdown your computer before removing it from the dock.

Also I could not find any sites still selling my laptop, so getting one may be a challenge

There is a version with a better cpu Here but i could not find any of these at all anywhere.

There is an even newer version with a 6th gen u processor here but it has a dual core cpu, and it is much more expensive (and also not available anywhere)

If there is any more info that i need to add, ask me and i will try to find it.

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

Thank you for your unique submission.  Would you mind re-running the CUDA-Z bandwidth tests?  Your present results, while good, are not quite reaching the host-to-device numbers we'd expect of 128Gbps x16 3.0.  We'd expect double the 64Gbps x16 2.0 result numbers as seen at:

Im not sure why it isnt performing as expected, as it is properly connected, it may be that my cpu cant handle the speed?
here are the aida results with igpu enabled>

igpu disabled >

I believe i am running into a cpu bottleneck because it hits the single core max frequency that i can attain... Edit: that doesn't seem to matter according to results online, it may be that the interconnect isn't properly shielded (and since the laptop's power is going through the same connector) there is interference that is slowing down the connection.

I am still past what any other connector (pcie 2.0 x 16 or 3.0x8) is able to do even in theory, (but 60% of theoretical performance or even 75% of real world max isn't great I do agree...)

So, after extensive testing, cleaning, and over and under clocking everything I can get my hands on, and nothing was able to get my memory write score over 9333 MB/s untill I decided to test my theory of power interfering with the pcie connection (by plugging in my laptop's power adapter while the system is docked, and there are tangible results>

This 100MB/s bump is repeatable, every test gets over 9400MB/s, confirming part of my interference theory. (the read speed is higher by ~50MB/s so not as great)

The problem is that the pcie slot, the dock's motherboard, and the laptop connector are not shielded, meaning that the slot is likely interfering with itself 🙁
There is no way to test or fix this that I can think of, so until I get an 1180, there probably wont be any better results from my dock in terms of connection speed.

Welp I randomly ran the test again and well the results speak for themselves :

this is much closer to true pcie 3.0 x16
I can only conclude this was a "wierd glitch" caused by such a strange setup, and a new driver fixed it?
who knows, anyways im glad its fixed (for now)

Welp, unfortunately after two years of (great) service, it has died.

It is just dead, nothing i have tried has revived it.

RIP

What's dead exactly? Laptop itself, Gaming dock?

It was TOP setup!

The laptop itself died, and none of my troubleshooting was able to do anything about it
im pretty sure the processor died, and replacing that isnt gonna happen

Hi..

Got the same machine, but in dock a GTX 1080 Ti + Silverstone SFX 700W.

The laptop has 16gb 1866Mhz Corsair Vengeance and 2x Samsung 850EVO 250GB / output 950-1000MB/s in Raid 0.

I'm looking into a tower, if interested in the laptop let me know.

I would like to get it,
however as I already spent all of my money on a new computer i couldn't give you a fair price for it...

No worries.

If you ran the machine for 2 years without replacing its CPU thermal paste or cleaning the internal fan/heatsink, I'd guess it is quite possible the CPU baked itself.

I've regularly opened it, cleaned and put fresh paste... since the dock+laptop has a number of fans, lots of dust packs around the internal cpu fan of ultrabook...

I liquid metalled it a year ago, and have cleaned it pretty regularly.
Tho it probably still cooked itself to death;
that heatpipe is not at all enough for that CPU...
