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!!!
