Topic: PCI-Express replicators (Read 624 times)
For AMD there is a limit of 8 GPU. I could run 8 GPU (4X7990) on a mother board with 6 PCIE slots, but on 10 GPU (5X7990).
Interesting, I'm curious as well. However, I remember reading somewhere about a similar (more expensive) hardware when someone mentioning the stock BIOS might be hard limited only handle 6 or 8 PCI slots so it might need some careful BIOS mod to work. And then there would probably be OS issues.

If there is no performance impact, you could add two of these on an H81 BTC motherboard and drive 12 GPUs from a single system.
The G1840 CPU has 16 PCI-E lanes, so it should work in theory. Using powered risers, there should be no power issue.
Has anyone tried these before?
