Hi Nando,

Just want to thank you for your software!!!!

At the moment I´m runing Windows 8.1 with my eGPU with no problems.

I´m using your DIY eGPU 1.20 version with my MBPr 2012 and Zotac 970, the performance is great, and the best part for me is how the internal MBPr temperature is reduced drastically.

What is really funny is I spended last weekend testing the eGPU with a coupple of friends and one of them have one huge PC, watercooling, 32 ram, Geforce 970, etc... when we test both with Heaven Benchmark I allways got high scores!! xD I feld so proud...

Another courious thing is before i bougth the 970 I was trying de eGPU with a GTX 660 Ti and it work without your soft doing nothing special, just install the drivers,

Thank you so much again!!

I am extremely close I can just feel it. In my situation the internal display uses intel hd graphics "wired" when I disable NVidia via device manager and reboot, however it only is able to be used as a windows graphics adapter because every time I try to install the drivers for it, it goes to a black screen and the computer reboots, with no evidence of the driver installing at all. That driver is the only thing I believe at this point keeping me from having NVidia optimus. It shows the Microsoft display adapter as the one used for the lcd and not the 650m of which I have the drivers installed for so it would say 650m under display adapter settings if it was driving it. I am a newbie on forums so I messed up attaching the photo yes I know.....

Really interesting!! If you have any success, tell us please

It will be great to use the egpu with the internal LCD with our 2012 MBPR!!

Sorry for my long absence, much other work in the meantime.

@toxec:

Only two 4700 mF capacitors because there're no more of them here, and a extra buy I'd no desire. Moreover several test runs and measurements have shown that they are sufficient.

@Charly:

Sorry, but my "Windows" are only for to let the sunshine in my rooms and look outside my house.

On my Mac's only run OS X

Is the same with me, but now with the eGPU I want to try some games and most of them are in Win

Hi all (French below)

Just to let you know I succeeded in using the automatic installation on El Capitan 10.11.1

I found the nVidia web drivers there :

Nvidia Web Driver updates for El Capitan (UPDATE 11/02/2015) - New Releases and Updates - InsanelyMac Forum

First I integrated the KFA2 GTX970 ITX card which is the only one I found that is correctly fitting the Akitio TB2 chassis. The only tricky thing is that I had to build a very very low profile 2x6 Pins connector to power the card, using some copper rigid wire and my soldering skills. This is not something I would recommend to newbies to soldering and electricity in general.

Then I updated from Maverick to El Capitan (not my best idea I must say), doing a clean install an restoring datas from clone.

I was absolutely not successful with the script at the beginning, Terminal was returning something like "thunderbolt device present but graphic card not detected" UNTIL I found out that the Thunderbolt to ethernet adaptor was interfering. I unplugged it and it suddenly worked…

After the script ran, I was able to restart and see the card correctly recognized by the OS, and to get an image on a second screen.

Heaven Unigine test brought up the performance from 30 fps max (without card) to 130 fps max…(with card)

Beware :

- I had a Kernel Panic when I tried to switch of the card

- I experienced very often painful and slow Macbook startup, had to reset Pram many times to solve this (El Capitan issue it looks like)

- After some resets I had to go back to nVidia Web Driver Utility to specify again to use these drivers (and not the OS drivers)

- After any restart I had to change back the keyboard language to French (Vive la France), very very boring El Capitan issue ?

- Davinci Resolve detects the card but is very instable (Resolve 12.1 issue with El Capitan ?)

The result is that I am going back to Maverick…the most stable OSX I ever had, and will install the card again.

I will put my feedback here.

En Français :

Ce petit mot pour partager mon expérience. J'ai fait fonctionner le script automatique avec El Capitan 10.11.1

J'ai trouvé les drivers nVidia web ici :

Nvidia Web Driver updates for El Capitan (UPDATE 11/02/2015) - New Releases and Updates - InsanelyMac Forum

Petit mot sur le hardware : j'ai intégré une carte KFA2 GTX970 ITX que j'ai trouvé en ligne chez rueducomm… c'est à priori la seule qui rentre parfaitement dans le chassis Akitio TB2, que j'ai d'ailleurs trouvé à bon prix chez macway (alors que je comptais le commander aux USA).

La seule chose un peu compliquée a été de fabriquer un double connecteur 6 pins très compact pour alimenter la carte sans que ledit connecteur empêche la fermeture du boitier.

J'ai dû sortir la Dremel et le fer à souder, donc c'est une bidouille que je ne recommande pas aux novice du bricolage de précision ou de l'électricité en général…les connaisseurs peuvent me contacter en MP pour plus d'informations.

Ensuite j'ai mis à jour le macbook de Maverick à El Capitan (pas la meilleure idée que j'ai eu on dirait) en faisant une clean install et une restauration de mes données à partir d'un clone.

Au début le script automatique ne fonctionnait pas du tout…Terminal s'arrêtait à chaque fois en disant un truc du genre "thunderbolt device present but graphic card not detected"

Jusqu'à ce que je me dise que l'adaptateur Thunderbolt - Ethernet était détecté et bloquait peut-être la procédure…une fois débranché cela a fonctionné parfaitement ! J'avoue que c'est peut être dit quelque part au milieu des 38 pages de ce post…qui a tout lu ??

Après redémarrage, l'OS a parfaitement reconnu la carte et j'ai pu afficher une image sur un second écran.

Heaven Unigine (un logiciel pour tester les GPU) qui donnait 30 fps max (sans la carte) donnait désormais 130 fps max…(avec la carte) En activant l'anti-aliasing à x2 j'ai eu l'impression que la carte s'étranglait un peu…une limitation certainement due au débit du Thunderbolt 1…

Mais attention :

- J'ai eu une Kernel Panic quand j'ai éteint le chassis (je l'ai fait juste pour voir, je n'ai pas été déçu)

- El Capitan démarre très souvent très très lentement à tel point qu'il faut souvent resetter la Pram…(problème apparemment connu sur El Capitan) pour retrouver un démarrage rapide

- Souvent après ces resets il a fallu re-spécifier d'utiliser les nVidia Web Drivers à la place des Drivers de l'OS

- Après chaque démarrage il fallait re-spécifier le clavier français (hyper relou !)

- Davinci Resolve voit la carte GPU dans les prefs mais est très instable (incompatibilité de Resolve 12.1 avec El Capitan ?)

Résultat des courses, je ré-installe Maverick et je reprends tout à zéro…je trouve El Capitan beaucoup trop instable et contraignant

Je mettrais la suite de l'aventure à la suite.

Hi, it looks like is a driver problem with our MBPR, at the moment is not stable in our system, I have random kernel panics with 10.11.1

It looks like the script is stable with our system MBPr 2012 15" Nvidia 650M + INTEL4000 using OS 10.10 as errin told me coupple of days ago, I didn´t test it allready.

Since errin’s Maxwell card gives quite a similar kext backtrace, I suppose that this is Mac hardware related issue, and the reason is the dGPU. Nvidia driver cannot handle both the dGPU and eGPU. Confirm that your MBP doesn’t suffer from GPU design flaw:

MacBook Pro Repair Extension Program for Video Issues - Apple Support

Wow goalque, it´s really courious, the main reason of my eGPU proyect is that I think that I have exactly these problem. Sometimes I have strange behaviour with the grafics, strange psicodelical images when you resize a windows or move between monitors, and another thing is that when it boots osx always have external black screen, so i have to disconect te external screen and connect it again.

Couple mouths ago I speak with Apple Care and went to apple store, they pass a couple of tests with no problems detected... I was surprise because in my oppinion the main problem was the really high temperatures reached by de mbp without fan control (Dota 2 105 celsius... to much for the system), and when in the apple store made what it was supposed to be a temperature test, the macbook remained cold, (i was touching the aluminium near the processor)

I thoutgh then a possible solution would be a egpu to process the graphics of the system and release the internal components decreasing the internal temperatures.

Well I foun´d another oficial apple service and its probable that they replace me the motherboard.

Anyway somthing really amazing happen today, the eGPU is working solid and stable in Windows 8.1, with no extra software in bootcamp installation¡¡¡¡

Since I tried a lot of different things I can tell that the problem has been resolved doing one or all of this thing:

- Change the thunderbolt conection on the Akitio (I´m using the upper plug)

- Uninstall the Script is OSX and uninstall Nvidia Web Drivers

- Install BootCamp 5.0 instead 5.1...

The actual state:

- I´ve reboot the system many times with no problems everything plugged,

- I shut down the system and the eGPU and start again with no problems

- Internal and external screen are working

- Both cards are in use 650M and 660ti

- Unigine Heaven has now 806 Score vs 692 Score in OSX

- When I close the internal screen it remains on

- If I use the thunderbolt ethernet adapter conected to the macbook the eGPU don´t work at all

I´ll post a couple of pictures later.

Really happy but I would like to uderstand what happend here...

I´be been trying reconcile my GTX 660ti with many methods in windows but I´m starting to thing that is something wrong with the model of the card and windows, I tried with win10 and win 8.1 with no results.

As I been using the eGPU with the 660ti and OS X with instability but fully working I know that my setup is working fine.

Is your 660 working with the akitio? Please, Can you explain me the steps you followed to recognize the card in windows?

Thank you

@Charly:

I missed the fact that you have actually 600 series card which is Kepler. Uninstall the script (sudo ./automate-eGPU.sh -uninstall), run again with -skipdriver option and report if that helps. Note that only Maxwell cards and older AMD HD series are stable with AKiTiO. Some Kepler GPUs may work, some may not. PCIe only powered 750Ti is not a reliable choice either.

Therefore, your issue may be different than errin’s since he has a Maxwell (GTX 960). Did you have similar kernel backtrace, including com.apple.driver.AppleMuxControl?

No luck with -skipdriver option, kernel panic again.

I´m thinking that the problem comes with the GTX660 IT, in Windows has been imposible to detect the card with many methods, but always black screen and reboot.

Do you know someone using a 660 ti with Akitio? As fas as I know I fond no one with this setup working...

I´m going to paste the error report maybe can help you, for my is like egipcian... Just tell me if you need I try anything else.

Thank you so much for your support

I’ve heard that v0.9.7 disables the internal screen completely with Nvidia dGPU equipped Macs, but does it stay stable? Have you tried gfxCardStatus “integrated only” mode? If you find a working combination (either with v0.9.6 or v0.9.7) so that the internal screen will always use Intel’s iGPU, it’s possible to automate this process.

Ok, I´ve been trying different combinations no one is stable with v0.9.6:

1- Automatic gfxCardStatus = NOT STABLE

2 - Force dGPU with gfxCardStatus + ClamShell Mode (Rebooting with the Macbook Screen closed) = NOT STABLE (Internal screen is not recognized by the system And shows frezed image

3- Force iGPU = NOT STABLE (Start system without external screen connected to te eGPU force the iGPU and reboot, without that is not possible to force it)

4- Force iGPU + ClamShell Mode = NOT STABLE (Repeating the steps to disable internal screen in step 2) * I thought this could be the good one

So no luck at the moment...

What it looks curious to me is that my software monitor iStat Monitor shows the usage if the GPUs and when the iGPU is in use only shows the iGPU in the monitoring screen, but when the dGPU is in use you can see dGPU and eGPU in the monitor software, is like the soft only things that the eGPU is connected when the OS is using the dGPU when in fact in both situations eGPU is in use

Last one is with Heaven benchmark running

Hi guys my name is Charly from Spain.

You can see my setup in the signature, but I,m buying probably the Zotac 970 that fit in the Akitio next black friday.

At the moment eGPU is not working right in OS X 10.11.1, the problems look like is my 650M iGPU but still finding a solution, now I´ve just installed Win 8.1 and I´m going to try with nando soft.

This forum is great, really nice and smart people¡¡¡

Yes no problem with Windows 8.1 and 10 only sometimes boot up can be frozen after the chime but if I successfully boot in to Windows it's 99% working fine.

You may tried to read the Implementation threads, as far as I know there are 3-4 threads with 650m MBP

Great news!!

I´ll find the threads and install Windows 8.1

@Charly

I didn't use gfxCardStatus since the previous OSX 10.11 worked like a charm but the issue just occur when I'm in 10.11.1.

I played Dota2 for 6 hours watch video fro 6 hours but no problem came up but sometimes 5 mins after boot up it cause Kernel Panic. For me I think this issue is just random.

As from goalque said, beta driver from nVidia may fix this.

Tried the beta but didn't work can't boot to eGPU have to revert back again.

Wow that's really good news, Im installing 10.11 in external USB Drive and confirm.

errin, Do you get Windows to work with the eGPU? I installed nando soft but can´t find the graphic card card before the compaction, I spend some time with it but I was not pretty sure that my eGPU implementation was working or not so i concentrate in OSX, now i know that is functional so i´m trying again, Any suggestion?

Maxwell cards require web drivers from Nvidia. That’s the problem as the same driver handles both the dGPU and eGPU. The script downloads the correct driver automatically, and -skipdriver option is meant only for Kepler cards.

Thank you, I understand know.

Newer cards as 970GTX have official drivers or the problem is in all Nvidia cards? Im buying 970 gtx this week but this makes me thing about AMD cards.

In your opinion which option is smarter?

I’ve heard that v0.9.7 disables the internal screen completely with Nvidia dGPU equipped Macs, but does it stay stable? Have you tried gfxCardStatus “integrated only” mode?

Rigth now is late in Spain and so tired but tomorrow will try all combinations in 0.9.6. and explain everyting

FORGET THIS JUST CAN`T FIND DELETING THE POST

errin this Is exactly the same with my mbpr, last kernel panic was during Safari browsing so i can't find any clear pattern in what Is causing The problem.

Next i'm going to force igpu, i'll tell you any news

Is your egpu working in Windows? I'll try wirth nando soft but Is not finding the egpu

First of all, thank you for your great job and sorry for my bad english...

My setup is :

MBPR 2012 GTX 650M

Akitio 2

GeForce GTX 660 Ti 2GB

PSU (450W) + Barrel adaptor -> Akitio + Molex to PCIe Conectors -> GeForce

I´ve used Version 0.9.6 as you recommendation for dGPU and I´m having random kernel panics after a frozen display.

I´ve used -clpeak with no problems and also Engine Heaven also with no problems.

I have two questions:

1- Do I need to install BETA drivers? I am not pretty sure if you are saying this to errin

2- As the problem looks like comes from how the system manages the internal GPU, Is it important to set up an specific configuration for te uses of the internal cards? I´m referring to disconnect automatic graphic change in settings or force the system to use only one card wit gfxCardStatus (I´m testing now disabling automatic changes and force with gfxCardStatus to use only the discrete card and no kernel panics in 2 hours)

Thank you for your help and tell me if you need to test anything with my hardware.

Sometimes I have Kernel Panic, do you know what might cause this?

<none>*** Panic Report ***panic(cpu 4 caller 0xffffff7f853c7bad): "GPU Panic: [<none>] 4 3 7f 0 0 0 0 3 : NVRM[1/188:0:0]: Read Error 0x00000200: CFG 0xffffffff 0x140110de 0x00100400, BAR0

</none>

Looks like we have the same problem with the 650M I´ve the same Macbook as you but with 8GB RAM.

Have you try to force the use of the discrete card with gfxCardStatus? 2 hours without kernel panics and benchmarking and video playback... I´ll tell you with final conclusions

If you find another solution please tell me.

Good luck!!

EDIT: Just launch Dota2 in Steam and another shutdown... force de discrete card did´t work</none>
