I finally figured it out!

ASRock only allows 22 pins (read it previously) and everytime i tried to make it work with all 5 slots, it only showed 4 GPU. I realized that it was the pci3 8pin slot that never worked and I realized that 16 + 4 + 1 + 1 = 22 which was why i got it working with 4 the first time and i ever was able to get it working since then!

Im leaving it at 4 gpu a rig and calling it a day, for now...

Thanks for the help Rhovac!!!

Hi,

I am currently struggling to configure even 3 cards to work at one time with my 970 extreme4 motherboard. I am using 3 r9 280x's. I have three powered risers. At one point I had four 280x's plugged and the motherboard was only reading 3. I removed the non-working card and now I cannot get that third card to work no matter what I've tried. I seen your posting about this issue. Could you tell me what driver version you are using and what you mean by the mobo only allows for 22 pins?

Thank you for the help,
