    First of all, big thanks to Dschijn, nando, goalque and the rest for their fantastic guides! EDIT:MUCH THANKS TO @goalque FOR THE SCRIPT TO GET THIS WORKING ON OSX!! Tested Computer: 2014 15" MBP with Iris Pro only; i7-4770hq @ 2.2 GHz (Turbo to 3.4); 500 gb ssd Parts List: PSU: EVGA 600 B1 80+ BRONZE GPU: Gigabyte GeForce GTX 970 Mini ITX Overclocked GV-N970IXOC-4GD Thunderbolt 2 Enclosure: AKiTiO Thunder2 PCIE box Cables: 2 Molex to 1 PCIE cable (to make a molex to barrel adapter) 2.5mm x 5.5 mm male DC Barrel Plug (screw terminals are the easiest) Monitor: Dell 1920x1080 ^^Not sure why there are links there... Procedure: 1) Install Windows 10 via bootcamp instructions here 2) Download latest Nvidia drivers here 3) Open Akitio enclosure 4) Line up the x16 on the graphics card with the physical x16 slot on the Akitio. Push in the graphics card and screw the top screws on the Akitio to hold the graphics card steady. Plug in the PCIe 6/8 pin connector(s) from the PSU into the graphics card. 5) Make a Molex to Barrel Adapter using the 2 molex to 1 PCIE cable in conjunction with the barrel plug instructions here As Dschijn suggested, I made the barrel plug with 2x molex instead of 1x molex by twisting together 1 yellow wire (12V) from each molex connector and 1 ground from each molex. The yellows go in the positive terminal while the grounds go in the negative; make sure the plug is center positive! Be sure to check polarity of the barrel plug with a multi meter to make sure it is center positive! 6) Plug in the molex to barrel adapter into the PSU's molex connectors. Apply the paperclip trick or adapter on the PSU's 20/24 pin connector 7) Plug the barrel into the Akitio's power input 8) Connect the thunderbolt cable from the Akitio into the Macbook 9) Connect the video output cable from the eGPU to your desired monitor 10) Turn on the Mac while holding "Alt" 11) When the boot selection screen appears, turn on the PSU (I use a power strip) 12) Count to 5/wait for the fans on the GPU to spin up 13) Select "Windows" on the boot screen 14) Install Nvidia drivers 15) Follow the prompts to restart the computer and what not. 16) Profit The Boot Procedure that works most of the time for me: Assuming everything is plugged in, power on the macbook while holding Alt When boot selection appears, turn on the PSU with a power strip Count to 5 or wait for GPU fans to spin up Select Windows Both screens should work. If not, turn everything off and try again. I use Intel's XTU tool to undervolt and underclock its boost speed to reduce heat output. I underclocked it to 3.0 GHz and undervolted it by -75 mV. There are UV guides on the internet I used EVGA's Precision tool to OC the Graphics card. I managed to get +190 MHz on the core clock and +350 MHz (+700 MHz effective) on the memory (probably could push further). I also use a custom fan curve on the GPU via EVGA's Precision Tool. Temps never go above 61 degrees Celsius. Games: World of Tanks runs everything on Max/High 60fps @ 1080p with VSync and Triple Buffering on Witcher 3 runs Max/High no hairworks smoothly with no noticeable drops Naval Action (In alpha) runs everything on max no AA (kills fps in this game at this moment) @ 1080p open world and combat CSGO obviously no problems BF4 high in multiplayer @ 1080p and 60 fps Warframe is smooth everywhere on Max including Physx @ 1080p and 60fps Fallout 4 is same as above as far as I could tell Questions are welcome even though I might not be able to answer all of them. EDIT: Almost forgot to mention the paperclip trick Images: http://imgur.com/a/I9jaf External 1920x1080 Monitor: Heaven 4.0: Extreme settings at 1920x1080 with extreme Tess. and 8x AA GPU OC: +190/+350 Score: 1310 Valley: Extreme HD settings 1920x1080 GPU OC: +190/+200 score: 2318 Firestrike: +150/+200 Score: 8980 +190/+200 Score: 9154 SteamVR Performance Test: VR Ready +150/+200 Fidelity could be higher with a higher overclock CPU: limited to 3.0 Ghz and undervolted by 75 mV via Intel XTU Note: It says Iris Pro Graphics for GPU but it actually tested the GTX 970 Fidelity: High 6.2 Frames below 90 fps: 0 Frames CPU Bound: 0 Windows 10 Optimus Heaven: same settings as above, +150/+200 Score: 1137 ~13% performance loss Firestrike (demo version on steam): +150/+200 Score: 7754 ~14% performance loss

    @Brian and @Khenglish, thanks for your inputs, guys. Turns out a Windows 8.1 clean reinstall helped identify the problem - it was an Intel Control Panel anti-aliasing option shown below: Leaving it disabled solves the problem entirely. Thanks for the suggestions, guys. Could you mark this post as [SOLVED] for future visitors?

    Hey there, i've bought the new iMac 5k (late 2015) and try to setup my eGPU (Geforce GTX 970 & Akitio). Running the eGPU in osx works fine with automateEPGU (thanks to goalque) and the newest nvidia drivers. I only have some problems with the imac display resolution but after pressing sleep and wake up again everthing works fine. But in windows i'am not able to get the egpu running. I have installed the latest nvidia drivers but its still not working. If i dont disable the internal gpu, the egpu is recognized but with error 12. If i disable the internal gpu, windows crashes while booting in windows. Hope anyone can help me

    So this is looking down as if you were looking at the motherboard. Pin 1 is in the lower right corner. The pad marked in red is definitely missing. For the orange blocks, one of the pads is missing within that block, but I'm not sure which because I put the chip on and can't see. The memory interface half that is active (the chips supports 128-bit, but only 64 are used) is on the left side, and other than that there are not that many required connections for a GPU. PCI-E will downsize as needed if defective, and over half the pins are power and ground. There are very few connections that should be required to detect if a gpu is present. I'm leaning towards incompatible vbios as the problem. For example, the driver sends some instructions (vbios stores gpu instructions) and expects a result, but since the instruction set is changed it doesn't get anything back. If I have a stencil for it though I'll reball it and use leaded solder. I did have a tough time with the unleaded using a heat gun, so it's possible it isn't on right. There are no shorts though so it probably is on right.

    I can confirm it works. Well at least we can use the eGPU to power on the internal screen and we don't need setup1x to disable the dGPU before booting into Windows. I've just tested it in my Asus G46VW using EXP GDC Beast mPCIe. I can have the 660m and 750 2GB on at the same time with drivers 361.82. I was even able to have version 361.75 in the GTX660m while at the same time version 361.82 in the GTX750 2GB. In order to "force" the GTX 750 to power the laptops internal screen all I needed was to disable the 660m in the device manager and restart the laptop. Not restarting would the mean that only the HD4000 would power the laptops internal screen. In my opinion this is a huge improvement compared to what we had before, specially in Windows 10. But on the other hand this should be like this since 2012... I guess its better late then never

    The risk was explained already by @Dschijn, but no I'm no longer running it with just 1. Got a better barrel plug that fits perfectly and decided to supply more power to my GPU since it's a pretty power hungry card. @Squidgy If you are gonna sell it, I know some1 that was interested on getting a case, so you both might be able to scratch the others back a little bit @Kr4nG would be the one. P.S. Sorry for the late response, was on a little vacation.

    CAN CONFIRM OPTIMUS NOW WORKS!!! Tested on Warframe and the game looks nice on the internal screen (yay). To get Optimus working on Windows 10, install driver version 361.75 released 1/27/2016 Boot procedure is now: plug everything in start egpu start laptop wait 30 seconds boot Profit Big Thanks to Everyone!

    ThrottleStop 8.00 b7 https://www.sendspace.com/file/i84h7g I think the latest version of ThrottleStop should work well on a Surface Pro 3. Post some screenshots if you have any questions.
