16 GPU's for Octane Render Tweet

[JaviAl]

I want to build a workstation with 16 Graphics Card using 4 Nestor NA255 Boxes, each one allows up to 4 graphics card conected to one PCI Express x16 slots.

Does Octane Render allow to use 16 GPU's connected by this way?

Thanks!

You can use 20 GPUs in Octane 3 rendering same frame/image/scene. BUT if you are using windows it's probably not gonna let you work with more than 7-8 GPUS in single system/machine.

It's not only windows, You end up hiting limitations of most motherboards..after 7-8 You will start having lots of headache, but some mobos allow You to go 12 & more..

What mobos allow 12 & more?

Tyan and Supermicro come to mind when I think of motherboards with heavy expansion. The only one I've used recently was based on this Tyan:

Loaded up with (8) 7970s and worked as advertised (after a LOT of tweaking power / fan settings for GPUs).
