eGPU setup on 2013 retina MacBook Pro (with GT750M) + Akitio Thunder2 (internal and external screen)


Hey guys, in this video, I will show you the
easiest way to setup an external GPU on a 2013 retina MacBook Pro equipped with a GT
750m dedicated GPU. With this setup, you will be able to accelerate
the internal screen or to use an external display. The laptop can still be used standalone. In this case, we connected it to a videoprojector. Don’t pay attention to the green strips,
that are related to the camera and not visible in real life. Here are the performance levels I experienced
with a GeForce GTX 1060. This is a summary of the overall system with the three GPU represented. About the hardware, I’m using an Akitio Thunder2 PCI express enclosure, with a EVGA GTX 1060 SC 6 gigs model. I’ve removed the power jack and soldered another connector on the free PCB footprint. We’ll start from there, with a unique partition. First, use the boot camp assistant to create
a bootable USB disk with the proper Macbook drivers You can setup your thumb drive with another
program, like Rufus, just make sure that it has an EFI boot method. On this model of Macbook Pro, the default
installation method is UEFI. You can check that using GPT fdisk. This part is optional on this model. If you see the words “protective MBR”, you’re
good to go. Otherwise, you can convert it using GPT fdisk. You’ll find the link of a tutorial in the
description Your Mac will then reboot and start installing
Windows. Once the installation is complete, you can
verify your BIOS mode by typing MSinfo32.exe in the start menu. If you check the device manager, you’ll
see that only the dGPU is detected at this point. The next step consists on installing rEFInd,
from your Mac partition. Just open the installation file, everything
will be automatic. Then, you need to mount the EFI partition
and edit the rEFInd configuration file. Type the two following commands and look for
the refind.conf on the EFI partition. Just delete the comment symbol at the beginning
of the line “spoof OS version” (old method) Reboot without pressing any key and select
Windows on the rEFInd screen GO back in the device manager, your computer
now sees two graphic cards, your iGPU and dGPU. I’m not sure if the next step is necessary
but you can install Display Driver Uninstaller to delete your dGPU driver. Look also for the Windows version of gpu-switch
and move it to your desktop. You will need visual C++ redistributable from
Microsoft to open it. I did install each of its versions, just to
be sure. Open the file integrated.bat with administrator
rights, check that it worked and delete your display driver using DDU. Choose to turn off the computer at the end
of the process. Now comes the tricky part, turn on your computer
and plug your eGPU when you see the refind screen As the iGPU has been set as primary, Windows
should boot each time without any problem. Open you device manager, you’ll see 3 graphic cards. If you open dxdiag, you can check that the
iris pro graphics is the one in use. Download and install Nvidia Geforce experience
and the latest nVidia driver. The device manager will be updated with your
GPU models. In my case, GTX 1060 and GT 750M. Re-launch gpu-switch, just to be sure, then
reboot. When rebooting, you don’t need to unplug
the eGPU. Now, the device manager shows an error code
12 on the eGPU, that has not enough resources to work properly. Just right click on the GT 750M and choose
to disable it. Relaunch gpu-switch and reboot. Now your eGPU works properly. Open the nVidia control panel, go to PhysX
and set it to automatic. This allows your eGPU to accelerate your computer
in order to use its internal display. That’s it, you can now play your games with
desktop class performance. Everytime you want to use your eGPU, you’ll
have to use gpu-switch and disable the dGPU. At the end of your gaming session, just remember
to re-activate your dGPU, otherwise you’ll risk a black screen at startup. For the supply, I’ve modified an Xbox 360
power brick. At first, I was using an Xbox 360 S adapter
but the wires were too thin, causing a voltage drop. Any game crashed and the GPU fan was running
at max speed. When playing a game, the current can easily
reach 8 to 10 amps. I hope that this video will help you, if you
