Re: Pcie 1 to 3 Port 1X Switch Multiplier HUB Riser. Which motherboard works.
People don't want to reveal the secret to getting more than 7 gpus working. It gives them an edge that they don't want to share. I remember reading that the motherboard's bios needs to be modded for 8+ to work.
For what it's worth, I had a go at 8 and 9 gpus on an MSI Z87. Board would boot woth 8 but only detect 7. With 9, the board just wouldn't boot.

To get 9+ you'll need to use QPI links if you don't want to have to mod a bios(or if you have to not much at all)
