Dual eGPU setup working on nMP + FCPX fix + Pictures via Instagram
What am I missing here?
BTW, I'm running the 1080 Ti in one eGPU and the 1080 in the other eGPU.
@imcalledandy What exactly did you do to get your machine to boot with both GPUs connected?
I had mixed success and I believe I've tracked it down to the 1080Ti card being a Founder's Edition - the nMP doesn't seem to like those so I'll get a non-reference card and test the 3 x setup again - more on that here: https://egpu.io/forums/mac-setup/can-you-mix-9-series-with-10-series/
Back to the point: try enabling -a mode in automate-eGPU and put your eGPUs onto different busses - i.e not bus 0. I found with my attempt at 3 x I had overcrowded Bus-0 as I had an HDMI connection running too.
BTW - I did get the Node and a Thunder 2 working
2013 MacPro 2xD700 [email protected] (AKiTiO Thunder2) + macOS 10.13.3
2017 TB MBP 2xGTX1080Ti-TB3 (Akitio Node) + macOS 10.13.4
@imcalledandy Well, I gotta say, I think that worked!
I ended up reinstalling the script twice since I didn't uninstall the web drivers the first time. I let the script download them the second time which seems like it allowed the script to take care of some remaining tasks. After my first attempt, the cards were showing up as Nvidia Chip Model which I knew was wrong and led me to my second attempt. I have 1 card and 1 display in Bus 0 (ports 5 & 6), and the second card in Bus 1 (first port).
There's a post you left in that other thread where you mentioned you plugged in your display AFTER you booted up. I took a cue from that and left my monitor off during startup and everything worked as expected. I'm not 100% sure if this is one of the tricks needed, but I was initially having startup issues with my monitor on at boot and both devices connected. I now have my second monitor in Bus 2 (2nd port) — connected after login — and everything is up and running.
I need to see whether or not having the displays powered on at boot causes that to fail.
Just joining this thread as I am thinking about potentially setting up dual eGPUs on my 2013 iMac. I just recently got a GTX 980Ti to work with the Akitio Node. I'm not super hardware savvy and this talk about daisy chaining and risers and whatnot is kind of confusing to me. But based on what everyone has been testing here, do you guys think that 2 Akitio Nodes would work on my iMac? Also seems like I wouldn't necessarily need to get the same card. I use Octane in C4D pretty heavily and I am LOVING the boost I get with the single eGPU (soooo much faster than things were before just using the internal GTX 780M), so they thought of it being even faster with a 2nd eGPU is making my mouth water 🙂
what exactly ist the "-a mode"?
thx a lot!
my routine was following:
1. startup & login with HDMI -> Display
2. plugin/start 1st eGPU (BUS=1)
3. unplug HDMI and switch to 1st eGPU connected via D-Port to Display.
4. plug/start 2nd eGPU (BUS=2)
everything is fine and recognized by system... have work with it hours for rendering nonstop.
now, the 3rd eGPU (Razer Core & Frontier Edition) arrived and i was sure that the was the method to run it....
5. every time i plug/start the 3rd eGPU (BUS=0), the hole System Crashed: display went Black; all eGPUS run the Fan at full speed.
do you mean not even a USB keyboard & mouse by: "It's best to keep them on separate Thunderbolt buses and have no other peripherals connected."
