@razvani Yesterday i was thinking again about this problem: if the issue is in the Adobe software used with thunderbolt eGPU, why we get the same results also with Davinci Resolve? Maybe the problem is with CUDA used a thunderbolt eGPU?

Well, if it's true, that's a terrible news. I bought my eGPU setup also for gaming in windows, ok, but the main reason was "I need to work faster in video editing". I think i'll sell my akitio and my rocketstore thunderbolt docking station and build something different in order to get better performance in OSX. I don't like to work in Windows T.T EDIT: I just found on the web that some gtx970 had problems with Adobe software also in windows. Some people said that a solution could be the bios update of the GPU. In order to do that, we need the file and an nVidia flashing tool. This tool is only available for windows or linux. Can i update the bios of the 970 in windows and then use the card on the mac with it's updated bios? Or this "information" for the card is like a driver which is saved only in the hdd used by the current operating system (windows)? In this case, trying the update will be useless.

Maybe the problem is that 970 isn't in the official list of adobe tested/compatible GPUs. But i know that one of my friends has a windows pc with a gtx 980 working very well with premiere, afterfx and davinci resolve. And also 980 isn't a compatible GPU looking at the adobe GPUs list. So i can't understand why 970 isn't working with editing software in my osx system also if the mac can detect it and use it to output signal to external monitors. I think that if I use 970 like external gpu on the mac but using windows on external hdd I'll be able to get it working correctly with adobe and davinci. And i think also that i can get the same results by using it in a "normal" windows pc, like the 980 i was talking about. But at the same time, I don't know how to fix this osx problem. That's so annoying.

Hi guys, i'm using MacBook Pro 15" retina mid2014 (intel iris only) with a gtx970 g1 gigabyte and akitio thunder2. I use adobe premiere and davinci resolve. In the first month I installed eGPU (november 2015) i tried editing and rendering in premiere and a quick test of colour grading in davinci. Both was running very faster. Davinci wasn't telling me that i couldn't use CUDA (I always got that alert message before installing eGPU) while in premiere i wasn't able to find any information but i'm sure, it was a lot faster in rendering. In the next months I didn't work on heavy video editing and I was always using my mac without eGPU plugged in. But in these days I'm doing again a lot of editing and i need my eGPU performance. Today I was using premiere and i noticed that it was very slow also in the viewer while i was working in the timeline, i couldn't get a good "real time" view. So i tried a rendering with and without the eGPU and it took the same time. But i also seen that when I plug eGPU in the thunderbolt port I can choose the "mercury engine CUDA", while without plugging the eGPU i can select only "mercury software only" or "mercury OpenGL". So it's like Premiere it's using GTX970 but it doesn't make any difference in the "speed" of the program. I've also seen in after effects that i can select GTX970 CUDA for raytracing instead of the integrated intel (but with the alert message that 970 isn't tested by adobe). In Davinci i can see that the used GPU is the 970 and not the integrated intel. I didn't test rendering/workflow speed in After Effects and Davinci. Tomorrow i'll try with and without eGPU plugged in. I don't know what to do with premiere... Months ago it was working fine! EDIT: now I noticed that i have to update CUDA drivers to a new version, maybe that's the problem, but i can't understand why having the old one means that it couldn't work like always before, only because there's a new one. I don't think it will change the situation, but i'm not an expert...

Ok, thank you for the info! Yep, i know that CUDA is necessary for editing software like Davinci or Adobe, so i bought the nvidia card But why in mac informations, under "monitor" i can see that monitor are powered by intel and not by nvidia? Is that normal?

Hi everyone. First of all, thank you for the script Goalque! But maybe i had some problems. I'm not sure of what i've done. I'm a beginner in egpu setup. I'm using Akitio + GTX970 Gigabyte + 550w PSU with a mid 2014 macbook pro with intel only graphic, no nvidia cards. This is the steps I've done: 1) Downloaded the script on desktop. 2) Opened the terminal and cmd+v the first line of code. Pressed enter. 3) the same with second line. 4) the same with third line. 5) Terminal asks me a psw but i don't know which psw it's talking about. 6) I repeat the steps and now the terminal doesn't ask a psw, but it tells me that i must connect the thunderbolt cable (i was doing this with the egpu disconnected) 7) I repeat the steps with the egpu connected and turned on. 8) The procedure starts. It finds the nvidia Quadro drivers. I want to avoid the installation of this drivers, 'cause before going on, i wanted to ask information here considering that i have a gtx970, so why the script downloaded the quadro drivers? Anyway I made a mistake and i pressed the comand to go on, so i installed the quadro drivers. Terminal told me that everything was ready and that i can restart. So i restarted the system. 9) Mac restarts and everything seems normal, nothing new. I haven't external monitor connected. I look in the mac info and i find that internal monitor is powered by intel iris. 10) I connected the external monitor and i found that also that was powered by intel iris. 11) I restarted the system and again internal and external monitor was powered by intel iris. 12) I opened davinci resolve 12 and the program says to me that it can't find CUDA. (But when time ago i used davinci only with intel graphic it didn't told me anything about missing cuda, so i thought that now he can see the nvidia card, even if cuda can't be found). I closed davinci. 13)I restarted the system without the egpu and I opened minecraft in window mode on the internal monitor. Pressing F3 i see that the program it's powered by intel iris. Then i restarted the system now with egpu turned on. I opened again minecraft in window mode on the internal monitor. It tells again it's powered by intel but performances are better. 14) I drag the window on the external monitor and now it says that minecraft is powered by GTX970. But now there are some frame-rate problems (game freezing one time every 10-20 seconds). And i also notice that macbook is hot, like when i'm doing a render in video editing software. 15) I try to close minecraft, but it stop working and i had to close it from the mac activity monitor. (It never happened in 5 months when i was using mac without egpu. This is the first time) 16) in the upper bar of the mac i can see that there is the nvidia icon on the right. From there, i opened the nvidia driver manager preferences and i can see that in "ECC", in the fourth slot there is the gtx970 while the other 3 are empty. And in this window, between nvidia web drivers and osx default graphic drivers i can see that is selected the first one: nvidia web drivers) 17) I decided to close everything, turn off the system and ask info here. What does this situation means? I think I made a lot of mistakes and I'm feeling very stupid lol. What should i do? (And i'm sorry for my bad english)

Hi everyone! I'm trying to build my first egpu setup and I have some doubts. Can i ask some questions about the PSU? I'd like to get some help, in order to avoid a massive explosion ahahah. I'm going to use a Cooler Master 550W atx12v (with my Gigabyte gtx970 and Akitio thunder 2 PCIe box) [ATTACH=CONFIG]16516[/ATTACH] I saw in this guide that i have to plug two 6pin in the gtx970 and one 6pin in the Akitio using an adapted cable that will allow me to use the standard Akitio power input. My questions are: 1) considering the fact that my PSU has three 6pin plugs, it's the same if i plug the P4 and P5 in the video card and then i use the P6 for the Akitio, or are they different and so i must know where which one of them must go in? 2) for the first question, i supposed that a 6pin plugs is 12v. It's right? And how can i know the A of these 6pin plugs? I saw that original Akitio psu is a 12V 5A. On the PSU there are written six outputs specs and no one has 5V for 12V. I'm so confused. Is this PSU ok for the eGPU system that i'm trying to build? Of course I'm not going to turn it on without this information and without being sure that it's all plugged in the right way. I'm sorry for my ignorance and for my bad english. Thanks to everyone who's going to help me! n.n

I made a mistake, i didn't want to post the reply (that now i'm editing, because it wasn't making sense in this thread) and i don't know how to delete, but only how to edit. I'm sorry...

Ok, so the akitio is empty because there isn't a pcie card (that in my case is my gpu) but anyway it has the pci female connector that i need to put there my gpu, right? Thank you for the hardware guide, it's been very useful also for the PSU info! And thank you for the help

Hi guys, i'm new in this forum. I'm sorry if this isn't the right place in which i have to ask this question, but i saw this thread about Akitio and i have a little question about it. I'm from Italy (I'm sorry for my bad english) and I found one of this thunder2 pcie box from USA, but in the title of the article there's written "without pci express card". Now, i don't know what that means. It's just telling that there is no GPU included? But that sounds too obvious to me... or it means that's missing another component that i'll need in my eGPU setup? I know that maybe it's a stupid question, but i'm so inexperienced with this kind of things and before throwing money i'd like to have some help
