I have a rig with 5 r9-270s in it and only 4 are being detected by the motherboard.  I know that only 4 are being detected by the motherboard because it is a MSI A88x-G43 which has a hardware display built into the uefi.  Has anyone had any experience with this problem?

What PSU are you using and are you using powered risers?

Try rotating GPUs to see if it's a GPU issue? Try rotating risers to see if it's a riser issue? Is your MB BIOS up to date? Does your MB need a PCIe presence mod? I use the PCIe USB risers, which have a built in presence mod.
