Hi guys

i am trying to use this mobo for mining but i could not get identified rx 6800 xt on this board via x1 to x16 riser cards. It does not get detected in device manager as well. It only works over the primary x16 Pci Express slot. So what changes can i make it to run on this board via x1 to x16 riser cards? I also could not find any gen settings for specific pcie slots in the bios if there is one.

Is there any configuration page i can mess with in the bios for pcie slot gens?

kind regards.

So far I have 5 1660Ti GPUs detected. I would suggest updating BIOS to 4.80 first and then disable CSM and enable Above 4G Decoding. The PCIe speeds so far as set to Auto. I have them plugged into slots PCIE1, PCIE2, PCIE3, PCIE5, & PCIE6.
