Not sure. I have not had this issue before. Just make sure that you are installing the windows 8.1 drivers? Other than that :/ ... A hard format and fresh reinstall is painful but tends to work.

Ah, It sounds like you have been doing what I did: Every single possible arrangement of the parts. I'm sorry to hear that it isn't working. For me, I used to turn on the macbook with the eGPU plugged in and it worked 75% of the time. The other 25% of the time, the macbook just wouldn't start (black screen). But shutting down windows/osx correctly often worked. Question: Do you always turn off the eGPU and unplug it before every boot? I got a slightly higher success rate if I : - Turn off my macbook pro - Turn off my eGPU enclosure (or attached PSU) and wait for around 10-20s - Finally turn the eGPU enclosure on and then the macbook pro. If that doesn't help then I don't know if there is much else to try :/

Can I check: - Do you have a Macbook Pro (Early 2015 13inch)? - Do you plug in the Thunderbolt3 Cable while the Macbook is off? - When you try to turn on the macbook, what happens? Does the screen stay black? What if you try to hold down the power button/try multiple times? - Does booting into Windows work without the eGPU? Have you installed the Latest Windows NVIDIA drivers? At the time, I was using 368.39 I believe.

Hey SnJae, I did try my eGPU with an external SSD (I bought a USB 3.0 SSD adapter). I installed windows 10 and still had issues booting, boot only worked once in every dozen tries. I tried the eGPU before the Anniversary edition was released but I do not remember which build number it was. It sucked to use windows 8 but the boot was *incredibly* reliable compared to Windows 10.

Hi Everyone, I recently build an eGPU setup for the first time with an NVIDIA GTX 1070 (https://www.techinferno.com/index.php?/forums/topic/10081-early-2015-13-macbook-pro-gtx107016gbps-tb2-akitio-thunder2-win1081-nasiryahm/) Absolutely loving it and thankful to everyone on the forum for sharing their knowledge. After building it, I wanted to make it look a little prettier so I went ahead and designed and printed two 3D pieces to vertically stand the GPU and the Akitio board (outside of it's metal enclosure). I wanted to share the love. I have detailed my build on my blog, here: https://nasiryahm.wordpress.com/2016/07/03/3d-printing-an-egpu-case/ And I have also attached the Sketchup files here. The Lower_3D file is the Akitio PCB mount. So long as your Akitio board looks like mines, it should fit perfectly (I would recommend lowering the heights of the pins though, they are excessive, again see my blog for details). The Upper_3D file is a mount for my GTX 1070. All question are welcome. Nas. 3D_Files.zip

Hi @cloudlee9 - I just ran Fire Strike (first time using 3D Mark, it's fun!). I have the following results and can post a screenshot on my blog maybe: Overall Score-> 7960 | Graphics Score -> 12760 | Physics Score 4899 | Combined Score -> 2761 How does that compare with what you are getting on the 970? (Plus, is your windows installation on the internal SSD?) One thing to note: I am running my windows os from a fairly slow mechanical external hard drive. I have already noticed that it is slowing down my laptop a large amount (and games loaded much faster when I used the internal drive). I am buying an external SSD drive with usb 3.0 and will update the scores when that comes through. @Barzenberg : Hey! Thanks for the suggestion - I have tried that a few times. When I installed via bootcamp I tried it for around 20 boots and it only worked once. I also tried lots of variations (as I didn't want to have to use an external drive). On my external drive I prefer to: Power off everything, insert TB2 cable, turn on eGPU, turn on Mac with alt. It boots around 8/10 times and that is good enough for me. I personally find the process of having to plug in the TB2 cable after the boot screen a little annoying, especially since I have my macbook on a stand at home. Each to their own!

Hi @jagung - There have been no drivers released for OSX at all yet. Since it is a new architecture, it won't work if I install existing drivers (as far as I am aware). There are quite a few people in wait for the new drivers :/

On looking around, tranJ10's post on installation for a macbook pro 2015 is a perfect explanation on how to move forward. https://www.techinferno.com/index.php?/forums/topic/8212-2015-13-macbook-pro-gtx97016gbps-tb2akitio-thunder2-win81osx1010-tranj10/ Also see his link for installation of Windows to an external drive: http://bleeptobleep.blogspot.co.uk/2013/02/mac-install-windows-7-or-8-on-external.html

Hi All, I'm new to the forums but I found a lot of great information here so I thought I would share. I have successfully run an NVIDIA GTX 1070 with my Early-2015 Macbook Pro. My setup is the following: - Akitio Thunder2 PCI-E Box - NVIDIA GTX 1070 - Powered 16x PCI-E Riser - EVGA NEX650G PSU (I know it is overkill, it was my only option in a pinch. Paperclip trick for power.) I have outlined the pieces, my excitement and some issues at my blog. Issues: - I initially had an issue where my system would not boot correctly with the eGPU powered and plugged in. The screen remained black and no boot chime. Booting into and shutting down from OSX solved this issue but it occasionally returns. - The first PSU I tried (EVGA 500W) would spontaneously turn off when I started using the GPU at high load (e.g. intense gaming). I replaced it with the EVGA NEX650G which I had from an old project. - Windows 10 still holds issues for me. I often have to get to the boot screen (holding alt at boot) and then plug in the eGPU + Power before selecting Windows. Even then I have a high failure rate (>70%). Windows 10 often hangs at the loading screen (spinning circles) and never moves on. This happens 3/4 times. I am currently re-installing windows 10 to see if it helps. When I get through to windows the eGPU works great. Tried with Witcher 3 @ 1080p with ultra-high settings. I believe that Optimus is also running with the current driver. If there are any requests for benchmarks, I am happy to do them. I am new to this world though and therefore don't know the defaults. Nas [EDIT: 23/06/2016] After using the setup for a number of days, I have come across a few problems and solutions. I am using a 2015 Macbook Pro and others on this forum have had issues making eGPU builds with this macbook. After installing Windows >5 times and Linux > 3 times, here are my outcomes: Issues: -> Windows 10 or 8.1 installed via bootcamp to the local disk barely works. One boot out of every 20 allows you access to the GPU, otherwise infinite spinning wheel or blank screen. -> Linux is a bit tough too as we are using an integrated graphics card. From what I have understood, to get the eGPU working you must uninstall the nouveau drivers and use bumblebee (for optimus on linux). Still trying to make that work. Solution: -> To get the setup working on Windows, install to an external drive. Following that, every time you want to use the eGPU do the following: 1) Turn off everything 2) Plug in the eGPU -> Thunderbolt2 3) Power up the eGPU and wait for ~10s 4) Turn on the Macbook Pro while holding alt and get to the boot option screen 4.1) It the GPU starts up but the mac does not, hold the power button until the GPU dies down and then try again. If it fails repeatedly, boot into Mac OSX and then shut down. 5) Success! This above technique has allowed me to boot around 7 out of every 10 times I try. I am now running Windows 8.1 but I shall also try this technique with windows 10 sometime. Much better. [EDIT: 03/07/2016] I created a 3D printed enclosure for my Akitio board!
