What you will need:

- EXP GDC Beast V6 with a mini PCIE cable

- Graphic Card

- 400 W Power Supply

- Optional a mini pcie to mini pcie extender

- modded Bios

For the eGPU mod i am using:

- EXP GDC Beast V6 with a mini PCIE cable. (lightly modded for gtx780ti)

- 400 W Power Supply

- GTX 780ti Gigabyte

- Optional a mini pcie to mini pcie extender ( it came today <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" title="Smile :)"> )

/ this can be used to get the mini pcie connecntion out of your blade. So you dont need to open the case everytime you want to plug in the eGPU

So how does it work?

First:

This is very important. I always got error 43 with this controller. After two weeks of dispair i realizes that the GTX780ti needs 2x 8 pin Power cables. But the EXP GDC just had 1x 8 pin and 1x 6 Pin.

So i modded the Cable to have 2x 8 PIN OUTPUTS.

Like this:

Reboot into the modded Bios. you will find the Graphic options under Chipset/System Agent (SA) Configuration/Graphics Configuration:

<span style="color: rgb(179, 0, 89)">

THE PRIMARY DISPLAY MUST BE SET TO IGFX ELSE YOU WILL GET BOOTLOOPS

(this option is set to SG from Razer/default)

You can try the other settings. for me it ended with reseting the bios many times.</span>

Power Off the Blade and open the back:

Remove the WIFI Card and Plug in the MINI PCIE Cable of the Beast ( or some other eGPU controller)

<span style="color: #b30059">

A HDMI SOURCE MUST BE PLUGGED IN!!! And of course the Power cables for the GTX780ti

(these are not yet plugged in in my picture)

When you boot into windows now, you will be able to install the latest Nvidia drivers. If it gives you errors and reboots, try to install it over the Device Manager.

if you have done it right all 3 Gpus will be recognized and GPU-Z will give you this:

I DID NOT GET OPTIMUS TO WORK WITH THE INTERNAL LCD. I think it can be done through right bios settings or setup 1.x

I get more than double of the frame rates with the GTX780ti,

with the 3D Benchmark Furmark :

- GTX870m gets around 40 Frames/s

- GTX780ti gets around 130 Frames/s

Yes 130 Frames/s

So thats it with the EGPU MOD.
