Is this going to make the egpu work on nMP in windows?

@goalque What's up with this guy "rominator" asking you to "come clean" so that he shares his insights on nmp egpu? If this thing is based on pride, then we are sabotaging ourselves. Can't believe how hostile he can be.

Guys, I'm trying to make a 970 work with a 2013 15'' iris MBP and it's only working with an external screen. I'm getting a black screen every time I start with the eGPU connected. I tried several startup procedures. How do I get Optimus working? I'm using the newest nvidia 362 drivers on Win10 64bit.

I was also thinking about this. Yes, it could be the problem. Davinci uses the integrated GPU for computing and the GTX for...i don't know what because it doesn't say. I was thinking about some CUDA tests, couldn't find one. I got CUDA-Z and it sees all the resources. Hm...

Same problem here. I tried fiddling with DSDT override but I couldn't get it done. I got errors on compiling. We don't even know if this works with the mac pro though. Hope there would be an automated process, like in OSX.

@Dschijn How did you cut the case for the plug? And how did you manage to mount the plug on the case? I'm at this stage now and I need to find a good and clean solution for this. Please help me out.

Yeah, I'm feeling the same man. Adobe is pretty bad at coming up to date, especially with the software itself and its problems. I mean Premiere CC has several critical bugs that are fucking up the workflow of any professional filmmaker. Adobe hasn't resolved most of the critical issues that were there for several years, but instead they're coming up with tiny glittery new functions like h265. This while not fixing the problems that are making people choose Avid over Premiere. Had a project this summer and I was strongly thinking to switch back to Avid due to their stupid little bugs. So basically I won't be expecting this fix anytime soon, mainly because they came up with an update for their apps to work with El Capitan, long after the OS was launched. I think 4 months after that. I was really stoked about the Metal API which was saying that would speed up Adobe apps (Premiere included) or AE rendering by 8x. So many people updated and guess what, they had to roll back. I was also thinking about getting rid of the mac pro and getting a PC to make a hackintosh. Actually my hackintosh that I had before was giving me better performance than this guy. Mainly because of CUDA. OpenCL is terrible in Premiere. The only inconvenience of the PC was the lack of thunderbolt and a more stable OSX. And a big case as well. I don't think I'm going to sell this. I'm just going to wait a little more. I think in 6 months this will not be a problem anymore. Let's all go on and submit a bug request to Adobe. If they get more requests, they will probably take care of it in the next update. Here's the link : http://www.adobe.com/products/wishform.html Let's ask for eGPU support in OSX. Cheers!

There are several cards that are not in the Adobe compatible GPUs but they work perfectly. I think it's a software thing that has to do with thunderbolt connected GPUs. When eGPUs would become more popular, I think they'll fix this.

@Dschijn Can you post a picture of how you cut the case for the DA2 plug? It looks like a nice place for the plug. I've used hot glue to stick the plug and the switch to the GPU's grill. Thing is - I can't use the 2 slot card holder from akitio anymore - that would be without cutting it. I don't really want to cut it so I think I'm going to do a rewire. I've ordered this custom cable that you guys were talking about. I spent a ton of time trying to get the pins out and back in, broken pins & whatnot. I hope this cable would help me do better wiring. As you can see in the photos, the wires are not so long and they're going into the back of the board - which is not great. Then if I close the case, the thick cable would touch the copper pipes and I'm afraid that this would damage the cable when it really heats up. Did you remove Akitio's fan? I haven't removed it for now and I'm not sure if that's necessary. I could keep it and put it the other way around so that it pulls air from the case. For now, I'm feeding all the DA2 12V positions into the GPU and I'm also using Akitio's PSU. I've read about some instability issues so I've built a small PCB with 3 2200uF 24V capacitors. Do you guys think these would work fine? Would using both Akitio's PSU and the DA2 work fine? Or is it just a matter of many cables? I figure that if I use both PSUs, there wouldn't be any need for the capacitors. I'm also thinking about not using the barrel plug, but soldering the cables to the back of the case plug.

@Schecter I've also tried my GTX970 with Premiere 2015.2 on a 2013 Mac Pro. Yes, I can choose CUDA for rendering but it doesn't seem like it's doing anything though. I tried to open up a project I was working on and every time I opened it with the eGPU plugged in, it crashed. Turns out it was because of the full screen playback setup which got confused and just crashed the program. I then restarted, unplugged the eGPU, opened up the project, turned off the mercury playback engine, restarted, plugged in eGPU, opened up project, it worked. Didn't feel like I was getting any better playback performance. This is something that Adobe needs to fix within the software. But how do we get them to fix that? Tried After Effects rendering with the untested Raytracer - it just doesn't render. DaVinci shows the card in there but it's not using it for computing. It's using the internal D300 instead. I had a GTX660 in my previous PC and I was getting way better playback performance than the D300 with openCL. Huge difference. I could even send a file to AE, do something there and then go back to Premiere and play that in real time without even rendering. OpenCL can't do that.

Thanks a lot for this. I thought I was doing something wrong.

I've installed Windows 10 (UEFI mode) on my Mac Pro 2013, I've built a Galax GTX970. I still need to work on the wiring and the case but it seems to be working fine for now. It works just fine on OS X but I can't get it to work on Windows 10. I've installed all the drivers and I still see the card in Display adapters giving me Error 12. Does anyone have any idea about this?

I'm having a hard time finding the 2200uf 16V in the stores around me. They have 2200uf 25V though. Would these be ok?

Well, I guess that I've just rushed on this now. Hopefully there would be some future development that would make it work.

I'm building my GTX970 rig now for this exact purpose. I have a 2013 mac pro though, I hope it will work. I'm sick of AMD graphics and openCL.
