Hey all!

I have 7 GPUs but I only have a 4 PCI slots. 1 16x, 2 8x, and 1 1x.

I have looked into splitters, risers, and such. I would love to install the 4 extra GPUs into my machine though they don't fit in the tower.

Would anybody have some recommendations about how to go about creating this?

Thanks all!

You can soon see all of the buildlog & know more about the process

I had such ambitions a few months ago. I ended up putting the GPUs in two machines instead of one, it was just getting too fragile.

Hi, I use the Amfeltec GPU Cluster and it works really well. On my last animation I used 3 Titan Z s in my workstation and 4 980ti cards in the cluster. It was easy to set up too.

canada computers told me that with my motherboard that has 5 pcie slots, even if i use the gpu cluster from amfeltec the motherboard wont be able to support it because of the limitation of cpu and motherboard lanes. Something like that. I dont know exactly how this is.

Can i get this cluster too? cuz i was just in the midst of building another computer to network with mine, mining rig + evga sr2 classified motherboard, xeon cpus, 7 gtx780 6gb watercooled.

Hmm, I don't think the 5 GPUs in the main workstation will make it impossible to use the Amfeltec Cluster. There are a few users on the forum who use the clusters with fully loaded systems.

I'm not sure if you've seen it already, but here is a thread with lots of good info from users hitting the outer limit of what is possible with external gpu computing.

7 GPU Rig

but...if u have Middle Scenes, more GPU's bring nothing.
Only if Otoy allow OneGPU/Frame Rendering....
