Hi everybody,

I'm just want to write something about my storie. Because I think it will help people who are considering making a External GPU.

I already apologize for my mistakes in English, it's not my mother tongue.

So, First of all I introduce myself : Mr. MoMo, i'm working for the Swiss Air Force and sometime i have a lot of Standby time during the day or night.

It's why i decided to buy a Laptop :

Lenovo T420s - Intel Core i7-2640M CPU 2.80GHz - 8Go RAM - with add GPU Nvidia NVS4200 - on Windows 10 64bits

I choose this one because i got a very good prices at my job 😀 !!

But after playing game like Counter-Strike GO, Cities Skyline, Kerbal Space Program and DCS World simulator. I realize that's not a Gamer Laptop indeed. And i don't wanna buy one (too expensive).

After some search to find a way to change my graphics card, I came across a forum that spoke about external graphics card. I said to myself "Yes it's for me". I've all ordered it and I started installing it all.

First, I bought a AMD Radeon RX 460 4go, with a PCI-E v8.4d EXP GDC with Express card interface version, a power supply, a 120mm fan, and a M/F HDMI cable.

So I installed it all in a box of ammunition that I had at home, and let's go playing.

 

After hours of manipulation to tear my hair because it did not work, I read on a forum that because of Nvidia Optimus I will not be able to display without an external screen. After I felt stupid I bought a Nvidia GTX 1050 Ti 4Go instead.

At that time it started to work as I wanted, but I had a lot of worries about putting the right drivers that works without crashing. I read all that I could do on this forum and I have all tried.

And finally here is my method that works through several of you. I started by disabling the PCI-E port of the NVS4200 card in the "Device Manager", then I selected the "High Performance" mode in "Power Options" and then I clean all my old Drivers with DDU, then I installed the only driver that made my computer error-free with the EGPU (Driver Nvidia v.375.63), And I disabled the windows driver auto update.

All worked until I launched the game Cities Skyline. After 3-4sec of games, or during charging, I had the super blue screen windows. So I start looking everywhere why. I find it, it was a graphic problem.  F&ç%*/&%/+"*ç*" ..... a lot of hours for that....

Somewhere a read on the FAQ on Steam it was maybe the temperature of the GPU... So my solution for that, it's to put an Program which allows to see the temperature, and test the with FurMark. And then that right... When the temperature rises without the fan increasing speed, Bing blue screen!!!

So I've downloaded MSI Afterburner, and I've changed the fan curve so that it will turn on very early as soon as the graphics card's temperature exceeds 23 degrees in idle.

In Mod 1, everything is automatic:

And Mod 2 is Full power.

And now all works perfectly, with having tried a FurMark and after launching my game. All is stable, the fan is running full, and I have no problem. It took me a long time to do all that, but I'm happy. Thank you all for your valuable help, and I hope this will help some as well.

Sorry for the long text

MoMo

Hi,

I'm not lucky today, Nvidia don't want to run anymore.

As you can see, there's my graphic card, and she's working well. But the Control panel from Nvidia is not there, and i can't see my graphic card in MSI Afterburn. (it's in french, but you can see the problem)

Do you have any idees ? Thanks
