Hi everyone, first time poster.

I bought one of these Micro ATX boards for a project - namely, putting a few GPUs on them. It was the cheapest board I found with 4 PCI-E slots on it (1x 16 and 3x 1).

I got the rig finished, using 4 extender cables w/ powered molex connectors. However, the motherboard will not detect anything other than 1 of the GPUs, despite there being 4.

I am unsure if this is an issue with the board, the bios needs updated, or something else. Much appreciated if anyone can help. I've build other systems similarly from Z77A boards with multiple GPUs, and have never had this kind of problem.

Thanks!
