7 x XFX RX480 8GB - MSI Z170A GAMING M7

Of cource i use the latest bios, because without it you can run only 4 gpus. I made a lot of different tests yesterday and now i can say - only 6 gpus can run on msi z170a m5. I also have two z170 gamimg pro carbon, may be it can runs 7 gpu, but i dont beleave it )
