I have pretty much the same motherboard as you - I have an ASUS P8Z68-v LX
I currently have 2 R9 280x cards running on it. I am using risers for those, connected to the PCIe x16 slots. I also have another two of the same cards connected to the x1 slots with powered risers. I CANNOT get them to work though! I have tried everything I can find online - swapping cards/risers, changing motherboard BIOS settings and even installing jumper cables into the x1 slots. Nothing seems to get the other two cards to work though. There is power going to them; both green lights and both fans are spinning on ALL cards, just windows and CGminer are only detecting two cards.
If you find out how to get it running please let me know! I am desperate to get all four cards running on my system!
