I am a happy user of iMac pro. I want egpu! For cuda rendering in octane. What should I choose?
Akitio node or Sonnet breakaway box (550W)? 
In terms of availability/price - I should check local vendor.
In terms of drivers/recognition - which one is better?
probably I won't be running another extra display with egpu (just cuda rendering) - do I need a dummy adapter?

best!

I'm running 2 Gigabyte Aorus 1080 and 1070 boxes on my iMac Pro for Redshift rendering. Working without a problem.

Hello, 
With imacpro are you use macos or Windows?
İf you use macos which system are you using? 10.13.4 or 10.13.3?
İ cannot manage to work with 10.13.4 with Sonnet egpu 1080ti in it.

@killengage,
Hi, I have been trying to run a second ogpu box out of the iMac Pro without success so far.
Could you share your steps or set up to see if that could work for me as well?
Thanks!

Hi @J_H_D_H

I use the first and last TB3 ports for the EGPU's. If you use something else they share a TB3 bus and it is not going to work. I also use a domotica plug so I can switch on both ogpu's at the same time (instead of fiddling around with the power cords 🙂 ). Turn EGPU's on when you see your login screen. Oh..and I'm still at OSX 10.13.2. Hope this helps.

Thanks for the speedy reply.
I am using 10.13.3 which might already be the issue, but I will try the TB3 order you mentioned, and hopefully that can do the trick.
will let you know,
Best!

Hi,
Finally I have build iMac pro with my akitio node.
My specs are:
MAC OS 10.13.4 (17E202),
with akitio equipped with Gigabyte gtx 1080 wind force OC (or something like that).

I used drivers from nvidia: https://www.insanelymac.com/forum/topic/324195-nvidia-web-driver-updates-for-macos-high-sierra-update-04252018/

and cuda drivers from official nvidia website.
Then I used automated script to enable egpu in my 1system from here:  https://egpu.io/forums/mac-setup/script-fr34ks-macos-egpu-sh-one-script-all-solutions-fully-automated/#post-35722

I tried to run Octane Render - it works !!!
Although my card runs fine.. after 20
-40 sec of processing it starts spinning the fans at the maximum speed! And after it finished (I closed rendering app) It won't stop even in 15 minutes. Whats wrong? Is it card problem or drivers?

Also, when I turn akitio off I get black screen, if I unplug it, then computer freezes and restarts in some time (10-20sec). Ehhh.. any easy way to downgrade to 10.13.3???? I don't have any screen or dummy plug attached, so maybe screen problems come from here? And what about the fans? is there any good way to control them? I wish my system won't let them spin so fast, they are as noisy as vacuum. 

HELP!

I did. I installed newest MAC OS 10.13.4 (17E202),
with akitio equipped with Gigabyte gtx 1080 wind force OC (or something like that).

I used drivers from nvidia: https://www.insanelymac.com/forum/topic/324195-nvidia-web-driver-updates-for-macos-high-sierra-update-04252018/

and cuda drivers from official nvidia website.

It works. It seemed that fans running indefinitely at top speed was the fan controller malfunction (I discovered that the fans were acting weird even when that particular card was installed in windows pc as normal pci card) - I returned the card in favour of MSI GAMING X 1080 8GB, still waiting for the card to ship but I am full of hope.

I have to note that I did not install drivers on 10.13.3 previously. 10.13.4 was my first try.

It worked with the same way on my iMac Pro!

Good day. Does it work well with the render engines and cinema 4d?

Hello @wawa Jey,

It works perfectly, I'm using 2 EGPU's with Cinema 4D and Redshift.

Hi, how you manage two egpu in one system could you share some pictures for us?
Thank you so much. 
İ have imacpro and Sonnet with 1080ti thats working well right now but two cards would be great.

Good day.

I did some thorough research on this and what I found related to me as a freelancer.

First was the fact that GPUs are very pricey. I found out that the crypto currency boom had  increase the prices of GPUs, but now that’s done and NVidia has lots of GPUs to offload but word is they launching a new GPU 21  August 2018. I would wait for that before I buy any GPU.

Secondly, GPUs consume a lot of electricity,  be very careful you don’t buy 2 1080Ti that has a power consumption of an oven, the pro cards almost better when you consider the fact that you have to pay for electricity if you’re a freelancer. Because even on idle they consumer cards take a lot of power. 
 
Forgive my English.

Long time lurker, first-time poster... (also posted the same question in the other iMac Pro eGPU build thread)

Firstly, great community here and one of the only places I've found that talks about the eGPU compatibility and how to get it working well.

So I have a question mainly for those using either Octane or RedShift. I also have the 10 core iMac Pro - is there any speed/performance reductions when using the eGPU setup on the iMac Pro compared to using the same 1080 ti card in a PC build?

And has anyone experienced any problems using either of these 3rd party renderers in C4D?

I'm presently using either the physical renderer or Cycles 4D - both very slow with the onboard CPU processing so i'd like to upgrade and use a dedicated GPU renderer.

Thanks in advance!

I'm trying to setup my iMac Pro with a Sonnet/GTX 1080ti combo and feel like I'm so close, but can't quite get there. I thought I might post in this build as they seem similar in nature- any assistance is appreciated! From other threads I've gathered that a system info or dump can be super helpful to those trying to assist and troubleshoot but I'm honestly not sure how to get my system to spit that info out- please let me know and I'll be happy to post asap. Through a combination of those two scripts, various patches, and referencing other posts, I feel that I'm close- the system is at least aware that an NVIDIA chip is connected (I think as both card and Sonnet both light up)- but I cannot get over the hump to full functionality! Any help and guidance is appreciated, thank you so much in advance and let me know if there's any further info I can provide!

Tried:
- Referenced build guide and mirrored processes for both the two iMac Pro builds as well as iMac 5k
- Includes installing web-drivers with SIP enabled
- Installing CUDA elements from https://developer.nvidia.com/cuda-downloads?target_os=MacOSX&target_arch=x86_64&target_version=1013&target_type=dmgnetwork
- Ran both- automate-eGPU-EFI - and - purge-wrangler.sh

Currently:
- Start up with eGPU unplugged, plug in at log-in screen, log-in, and Sonnet lights up as well as EVGA colors on 1080 ti
- System report shows 'NVIDIA Chip Model' under Graphics/Displays but does not identify specifics of card
- No device found in the ECC of Driver Manager

OSX 10.13.6
CUDA Driver Version: 418.243
GPU Driver Version: 387.10.10.10.40.130
NVIDIA Web Driver: 387.10.10.10.40.130

Pending: iMac Pro 10.13.6 / Sonnet 550 / NVIDIA GeForce GTX 1080 Ti
