Dual eGPU setup working on nMP + FCPX fix + Pictures via Instagram
Sooooo..... Finally got some success with eGPU and FCPX 10.3.2. Had to use a Displayport to HDMI 4k 60hz adapter. Found it on Amazon. Came straight from Titan Z to my 4k display. Thankfully I am only using a single monitor. If I plug in a HDMI to the Titan or the Mac Pro to get a second monitor in directly and launch FCPX, it crashes again.
Also I am still only able to get a single Titan Z or 980ti to boot in Sierra 10.12.2. However it is nice to have FCPX and Octane working without having to restart constantly. thanks all for the help.
Quick question: have you tried daisy-chaining the two eGPUs (assuming your Akitio cards have two thunderbolt ports)?
I have a build very similar using a 980Ti with the cards from a HighPoint RocketStor 6361A in a Silverstone SG13B case.
I've been debating adding a 2nd identical setup for the Octane/Cycles speed gains (and hopefully DaVinci Resolve also). Which got me wondering:
There's a lot of empty space in these cases, and SFX-L power supplies exist up to 800W which would comfortably drive both 980Ti cards.
If the two Thunderbolt cards work daisy-chained, I'm trying to figure out if the entire two-card setup could be fitted in one (perhaps custom) case with a short internal cable connecting them?
(Or if anyone who knows more than I do could chime in, is there any kind of daughter card or riser that could put two GPUs on one thunderbolt controller card?)
PCIe switch-capable risers exist. They can be used to connect two PCIe devices to a single physical slot by switching PCIe traffic between the two devices, each in their own downstream slot. They do not tend to be cheap, though (except of single-lane ones that can be found for relatively cheap on ebay).
