Hey everyone,

What is the best way to have a 8 gpu render farm?

I know how minners do it with ricers ect... question is will i lose performance? as those ricers are slower then the pcie speed ect...


I just wanted an open case rig...like you see many miners do...

Every card will have it's own watercooling...AIO...

Now i have 2 x gtx 1080 ti gygabtye waterforce...so i just need 6 more something similar.

I wanna build something like this: https://www.youtube.com/watch?v=lH00EIPQHFI&t=386s

Just scared to lose performance cuz of the risers.

I am not sure Mining Rigs (no PCI 16x) are suitable for Octane…

by using x1 instead of x16 You are going to loose, especially time when a lot of info should be uploaded fro mCPU/RAM to GPU VRAM, however rendering itself is going to run more or less at the same speed.

it's difficult to evaluate the importance as You would have to test on a lot different sets + v4 is coming with changes and this might effect results as well.

overall having x16 risers (or even placing cards directly) in capable board + fast CPU would be the best deal, but it's most costly option as well.

personally I would not recommend using x1 riser, but this route works & for now it's more than capable to do the work with smallish penalty in performance.

What the future is going to bring (with V4 & new cards, RTX, etc) , how important the speed of PCIe is going to be remains to be seen.

Funny enough, after writing this post i went to do some research on youtube and i found the video of you in it :p 3 hour video where u explained all of it :p

Thanks for the support and after Quadro RTX i'm defently going to wait...the presentation was crazy...

cheers

Thanks for your reply, i decided to just wait. Seems 2x quadro rtx 6000 is going to be faster then 7-8 x gtx 1080ti's...:p exciting times.

I am waiting as well for building my own 4 GPU rig.
I am specially waiting for the 2080 serie GC (not Quadro but "simple" Game card from Turing technology)…

me too :p quadro rtx 6000 seems ot be 8-10 times faster then gtx 1080 but it's also 10x it's price...but more memory ofcourse...
and u can just put 2 inside a machine and done...

Let's hope the gaming ones can do similar speed with less ram...i dont need much ram :p
