Title: eGPU Setup Help for OSX
Post by: pixxelpusher on June 06, 2016, 02:59:02 PM
Hi all, I've set up a eGPU with the following: AKiTiO Thunder2 Enclosure, EVGA GTX 980, Silverstone SFX 450w modular power supply, Mac Mini Late 2012 (OS X 10.10.5).

I've got all the hardware working together, but how do I get the Mac OS X software to run the enclosure as a eGPU?

Any help would be great, and thanks in advance.

Ok I've managed to get it up and running in OS X using the automated script people keep talking about on GitHub. I'm not sure if there's a better way to get things working? as nothing's been mentioned.

So far the setup is holding strong through a few benchmarks I've done in both Mac and PC Bootcamp, and I haven't had a crash yet. Also starts up every time, don't have to do any weird timing things with my card as some do, just plug it in and switch on the computer.
 
I've attached the results of some tests I've been doing and it seems to perform similar to when the card is in my Mac Pro desktop, maybe 10-15% performance difference depending on the task. Also I measured the power load taken by the PSU using a wall outlet meter and it measured 211W max during the Heaven benchmark, all other tests were below that amount.

Good job !

Glad you are enjoying it.

Pretty amazing to have a small low power machine suddenley bumping shoulders with the big boys.

Yes it is a bit of a game changer!

To have a small portable system that's almost as fast as a full desktop rig is what I've been dreaming about.

I'm planning on using it for VR for both work and play.
