Ok so when i get more cards and use risers ive basically got to try it and see what happens lol. Currently using the two PCIe3 16x slots but have three PCIe3 x1 slots i can use aswell.

All settings are set to auto so i suppose ill give it ago when i finally get more gpus. Just thought i would ask to see if there was a definitive answer   Smiley

It depends on the motherboard and how many cards you have. You should use the highest PCI-E  setting that is compatible with board. With multiple cards using all the PCI-E slots, some boards will only work if it's set to GEN1 or GEN2.

Looking to switch to using risers for my little hobby rig. Currently two cards in the mobo pcie slots. Bios settings are auto, would i need to switch to gen1 settings in the bios if i wanted to use other cards in in the regular/smaller pci slots?

Mobo is Asrock Z270 Pro4.

Cheers.
