eGPU with discreet AMD GPU on Macbook Pro (help)

Recommended Posts

HI,

I'm trying to get my egpu going on windows (for the time being I don't care about OS X), and I can't barely get started. Akitio + Evga 1070 

I read many guides but I still don't get it. 

 

Right off the bat the Thunderbolt or Basic Display Adaptor doesn't even show up on Windows Device Manager. I think I read somewhere that Windows needs to boot with the Intel graphics not the AMD and in order for that to happen I need to mess with the EFI to make sure the Windows boots with the Intel and not AMD?  If that is the case, i couldn't find any instructions on how to do that properly. 

 

I really appreciate any input or help! 

 

Thanks

I need this too mate. Let me know if you find anything.

So I made some progress. 

You need to install reFind. Here is the guide I used: 

 

NOW , a  difference from this guide: 

1- I installed reFind via OSX. I installed by booting with cmd option R and then terminal, and ./install something like that  (the guide says to use windows)

 

Maybe that is why mine won't work. But everything else matched the guide. I didn't install reFind from Windows 10 because Refind author says not to do it, because on Win10 things are different. 

 

I am at the point that I have the Iris gpu and disabled the AMD one, but the Nvidia 1070 won't show up on Device manager.

@macfan, suggest you pursue getting the eGPU detected in OSX. That would then at least indicate it's working. Until then it points to you having faulty hardware.

 

Excellent idea! I also ordered a PCIe Network card to see if I can get it going on windows. But I like your idea better

It did not!. OS X see s the Akitio box and that is it.    I replaced the 1070 with an old PCI video card (nvidia too), like REALLY old, and OS X sees there is something there (A VGA Card) and Windows sees it too (Basic VGA Adaptor) 

 

So bad card... ALL THOSE HOURS thinking windows was the problem.

      With AMD's long awaited Navi release, do you plan to purchase the 5700/XT?

      Following the release of NVIDIAs new 436.02 driver which I mentioned in an earlier article here, I've decided to make a quick and dirty video showing off NVIDIAs new Sharpen filter which is part of their Game Filter feature. It works with the most popular APIs including DX 9, 11, 12 and Vulkan and can be set on a per-game basis with granular settings of 0-100 unlike AMDs RIS which is limited to Navi and lacks DX 11 support.
