So today we build a expansion chassis using cheap usb risers and put them in an enclosure for neatness. I use this for Octane Render but it can be used for any GPU render systems/engine. The Riser cards can be found; Case i used the Fractal Design Node 304; Hope you enjoy :) I have a blog all about GPU’s in compute. Feel free to stop by and have a read, im building a community on GP-GPU and would love for you to stop by. Web: Twitter: Insta: Have a request? Email us @ [email protected]

I tried to make a similar connection 3 x 780ti on Asus x370 Ryzen 7 using Riser USB 3, such as in mining and I failed - even if I was hooked the third GPU in pcie it did not want to Win 10 work, now I succeeded, but on Riser USB does not see the rendering program, gpu - it sees it so but it does not display all parameters.

Boot test at the end... the GPU fans stopped spinning, is this normal? I'm sure they are always suppose to be spinning even if the speed is auto throttling based on GPU load.

Very interesting video,did you do the splitter video? trying to get more than two gpus on a mac pro without cubix or some other expensive box is quite a challenge?

You mentioned you have seen only a small performance loss with USB risers. This is when you're actually rendering on the cards but does not apply when testing with OctaneBench? Using such risers gives me a 20% lower score.

is it possible to connect such a 3X-SLI E-GPU system to a laptop with USB-Tupe C for rendering in Redshift ?

Good idea. I thought about doing something similar, but didn't quite know how, and wasn't sure if the bottleneck loss would be worth the expense and time. You've pretty much shown that there isn't a significant loss of power using this method, and seeing how you did it clears up some issues I had about the process. Thanks.

I bought a laptop from PCSpealist in the UK, with custom built hardware. Chassis & Display Octane Series: 15.6″ Matte Full HD IPS LED Widescreen (1920×1080) Processor (CPU) Intel® Core™i7 Quad Core Processor i7-6700k (4.0GHz) 8MB Cache Memory (RAM) 16GB HyperX IMPACT 2133MHz SODIMM DDR4 (2 x 8GB) Graphics Card NVIDIA® GeForce® GTX 1060 Power Supply 1 x 230W AC Adaptor USB 1 x USB 2.0 port 3 x USB 3.0 ports (USB 3.1 Gen 1 Type-A) 1 x USB 3.1 Gen2 port (Type-C) 1 x USB 3.1 Gen2 port (Type-C) Thunderbolt Combo Port Thunderbolt Yes (via USB 3.1 Port) So is this laptop support eGPU enclosure

belnder cycles supports multi gpu. and starting with 2.79 you AMD cards will run better than nvidia cards do with CUDA support. also you could use AMD readeon ray pro and use multiple AMD GPU + AMD CPU to render at the same time

Usb 3 made bottlenek? Always better use the thunderbolt 3

Thaaanks! Just been looking for that all week!! Was in my mind but at the end somebody who test it before! Gracias!

Hi Phillips , did you get any feedback on your gpu expansion tests ? I'm Octane user too and would be interested in such gpus expansion .

isnt there a limitation on how many gpus the cpu lanes can handle..when i built my computer they told me my cpu can only handle 5 gpus because of the lanes. i have i7. im not a pro at hardware so cant say more. i have 3 gtx 780 and a single slot gtx 750.. i would like to add more gpu can i or not?

How could you connect something like this to a macbook pro?

Hello my friend, your video is really cool and i want to make some chinese stranslations and upload to a chinese website.Is it possible for me to do that? I hpoe you agree :) (sorry but my english is not very good)

Really great project! It has me wondering though. How well do these USB Riser Cards perform in comparison to the Thunderbolt 3 eGPU solution you tested a while back? Also, would these be a benefit if paired with OS X and DaVinci Resolve?

I've been looking into GPU expansion myself and this has been very helpful. Thanks! Can't seem to find the 1 to 3 pci-e splitter video though?

Grrrreat idea! I will do the same thing, the case choice is perfect. Thanks for the inspiration 😉👍🏻

Very nice vid, please tell which PCI splitter was that at the end I need to test one too.

Dude, apologies if I glazed over this if it was already mentioned in the video but can this be adapted to be USB Type-C / Thunderbolt compatible?

Great video. Thanks. I hope this isn't an inappropriate place for it, but I have a very specific question. I understand that GPU render is preferable for many render tasks, though something I have never seen is the interplay between CPU and GPU. For example, it is commonly known that many editing and animation programs only use 1-4 cores during asset creation/editing and video playback. Most bench marking videos explore various GPU's but not CPUs. Would something like an i5 7600k run the general UI and playback tasks as well as something like a 6900k? Which is more important to smooth video playback (with regards to CPU) higher single core performance, or thread count? Finally, what impact does CPU have on the GPU render process? Obviously the CPU has to be powerful enough to send the information to the GPU, but how much power is needed? Does a higher core count CPU facilitate faster GPU renders? How do different CPUs stack up when the GPU is the primary render?

GTX 1080 Ti is being announced tomorrow, I am holding off on upgrading my GPU render machine to see what it brings to the table. So many considerations when building a GPU workstation (or a slave) and the Ti cards often hold their price well for a few years.

Out of curiosity (since this part was kind of glanced over) are all of those GPU's / USB 3's connected to your main box -- do each of them need a separate PCI-E x1 port to slot into...or are they hooked up in some other way?
21 февраля 2017, 01:16 Комменитровать
great idea. what was the performance loss ?

Hi Phillip, thanks for the awesome content you are bringing to the comunity. I always have been curious about those USB 3.0 risers! seams well built but not enough reviews on them. The idea of fitting the GPUs in a mITX case is genious :D and Fractal is just the best choice... I read your blog and im waiting for your 30$ expansion card test and benchmarks :D By the way, did octane reconized the build you did in this video? if so, can you talk about it? Thanks bro!
15 февраля 2017, 10:56 Комменитровать
Thanks for this. Cool set up and case. Curious, what's your overall set up and what octane bench score are you hitting now?

Oh man, I wish something like this would work on a MacBook Pro. I've got a Skylake PC but I also have a 15" MacBook Pro with a nice CPU that needs some serious graphics help.
