Dschijn Posted May 29, 2015 Author Share Posted May 29, 2015 If you want to keep it simple, it is not that hard. You just need the stuff to power it. Please read this thread: http://forum.techinferno.com/diy-e-gpu-projects/10061-basic-egpu-hardware-guide-macs.html From July I will have more time and might be more help Quote Link to comment Share on other sites More sharing options...
Dschijn Posted May 29, 2015 Author Share Posted May 29, 2015 Well. Get the point now!I added the switch now! ^^Got the inspiration from bsohn: http://forum.techinferno.com/provisional-guides/10099-2012-15-mbp-gt650m-gtx970%4010gbps-tb1-akitio-thunder2-win7-osx10-10-3%5Bbsohn%5D.html#post134736I just cut one of the crossbars of the ventilation of the IO shield and was able to perfectly fit in the old ATX PSU switch. Even the securing mechanism to hold the switch in position could get a good grab. Quote Link to comment Share on other sites More sharing options...
lovenf Posted May 29, 2015 Share Posted May 29, 2015 So if I just want to instal a simple epgu without modding anything. All I need to buy is: 1. AkitiO Thunder22. GTX 970 card3. A computer PSU Then plug the card to the box, then plug the power and turn it on, install the driver, enjoy. Is that right? Quote Link to comment Share on other sites More sharing options...

Yes almost.You will also need a modded barrel plug to power the AKiTiO with the computer PSU (please get at least 500W).Please read this: http://forum.techinferno.com/diy-e-gpu-projects/10061-basic-egpu-hardware-guide-macs.htmlAnd this: http://forum.techinferno.com/enclosures-adapters/8317-%5Bguide%5D-making-molex-barrel-adapter.html Quote Link to comment Share on other sites More sharing options...

I have a computer psu with an on/off switch so I dont need to mod any switch. And I think the gtx970 with 2*6pin maxium TDP is 225W, so 400W psu is ok.

Dschijn Posted May 30, 2015 Author Share Posted May 30, 2015 @lovenf: Well… you still need to do the paperclip trick, or get a SWEX/PSU starter plug.400W might be enough if it is a modern PSU and has 2x6-Pin PCIe plugs, but I doubt that!

seefew Posted May 30, 2015 Share Posted May 30, 2015 @lovenf: If your PSU is a newer one, the main switch only the power voltage turns on, there is no other output as a control voltage. You're have to do the paperclip trick to ensble 12V output. Quote Link to comment Share on other sites More sharing options...

lovenf Posted May 30, 2015 Share Posted May 30, 2015 Thank all of you. That paperclip trick works like the power button on the PC case. I understand now.So I think buying a Dell Da-2 adapter is more comfortable and simpler than using a computer psu. Quote Link to comment Share on other sites More sharing options...

Dschijn Posted June 13, 2015 Author Share Posted June 13, 2015 Currently experiencing a frozen system when playing GTA V for two times now. Not sure if it is related to the PSU or a GTA V problem.Not so demanding games like Heroes of the Storm are working for hours. Quote Link to comment Share on other sites More sharing options...
seefew Posted June 14, 2015 Share Posted June 14, 2015 May you'll take a closer look to the temps. My rooms are at the attic and during summer, temps rise often > 35° and more while it is winter temps below 15° in the rooms. Times i've worked on huge 3D models eg full body scan or engines (> 1 million polygon) my iMac works quite fine in winter but freezes during summer. 1 Quote Link to comment Share on other sites More sharing options...
Dschijn Posted June 14, 2015 Author Share Posted June 14, 2015 Since GTA V is putting a huge load on the i7, I increased the CPU coltage (from -75mV) to -50mV and could play for more than 2h straight.The CPU is also often close to 99-100°C with that game. Going to try to lower to boost clockspeed of the CPU with lower voltage as well. Quote Link to comment Share on other sites More sharing options...
Dschijn Posted June 14, 2015 Author Share Posted June 14, 2015 Update 14th June:OSX now working as well. Thanks to goalque for his awesome script: http://forum.techinferno.com/mac-os-x-discussion/10289-script-enabling-nvidia-egpu-screen-output-os-x-new-post.htmlUpdated the first post and added a lot of OSX GPU benchmarks.Edit: @Tech Inferno Fan could you please add to the topic OSX 10.10.3. I can't add that, since the titel seems to be limited in max length/characters to me. Maybe your admin powers allow longer titles? Quote Link to comment Share on other sites More sharing options...
seefew Posted June 15, 2015 Share Posted June 15, 2015 Maybe a additional possibility for your frozen system from 6-13-2015.Yesterday it was a very hot day. I've figured out the following: during about 5 hours of 3D modeling only the TB PCB of the Akitio becomes very hot also, until the system freezes, while temps of GPU and CPU are in a regular range.Greets 1 Quote Link to comment Share on other sites More sharing options...
Neogear Posted June 27, 2015 Share Posted June 27, 2015 Hi all, I have a Macbook Pro Retina 15'' 2014 with a discrete GT750M GPU card. I'd like to know if I can follow the Dschijn's guide with the AKiTiO Thunder2 Case + GeForce GTX 970 Gamer OC without modding the case. I'm going to set up all on Windows/Bootcamp and I'm wondering if disabling my current card's drivers does the trick or if there's still something I should be aware of. And what about the display? Should I plug it inside the GPU or to the case's thunderbolt port? Thank you so much for any help I could receive from you guys Quote Link to comment Share on other sites More sharing options...
Dschijn Posted June 27, 2015 Author Share Posted June 27, 2015 @Neogear: If you have an external display, you should connect it directly to the IO of the eGPU, not the AKiTiO TB port!For the installation, please follow this guide: http://forum.techinferno.com/implementation-guides-apple/8219-2014-15-macbook-pro-gt750m-gtx970%4016gbps-tb2-akitio-thunder2-win8-1-%5Btre87%5D.htmlHow do you want to cool the card without modding the case?

Dschijn Posted June 27, 2015 Author Share Posted June 27, 2015 @Neogear: The Galaxy / KFA2 GTX 970 Gamer OC is short enough to fit into the case without any mod! I did it to get best cooling options! Without any adjustments to the case, you will not be able to run the card with a high and stable clock speed. So cooling is compulsory. You don't have to disable the 750M, if you are going to use an external monitor connected to the eGPU (in Windows 8.1). Will work in OSX on an external monitor as well, yes! You must run the script from goalque and can't use an Filevault encrypted OSX: http://forum.techinferno.com/mac-os-x-discussion/10289-script-enabling-nvidia-egpu-screen-output-os-x-3.html#post136887 http://forum.techinferno.com/mac-os-x-discussion/10289-script-enabling-nvidia-egpu-screen-output-os-x.html Quote Link to comment Share on other sites More sharing options...
TheGrreatGatsby Posted July 3, 2015 Share Posted July 3, 2015 @Dschijn if you don't mind me asking where did you find the Galaxy GTX 970? I've looked everywhere but can not find any place that sells it Quote Link to comment Share on other sites More sharing options...
Dschijn Posted July 3, 2015 Author Share Posted July 3, 2015 Well I live in Germany and I guess you don't want to order from here right? Try to search for: Galax GeForce GTX 970 Gamer OC or KFA2 GeForce GTX 970 Gamer OC Quote Link to comment Share on other sites More sharing options...
TheGrreatGatsby Posted July 3, 2015 Share Posted July 3, 2015 Nope still could not find one lol, it's probably unavailable in the states Any other 970 recommendations that will fit perfectly into the akitio case? Amazon hopefully cause i get free one day shipping Quote Link to comment Share on other sites More sharing options...
