Hi I am setting up an RX580 rig with 12 cards and I currently have 3 cards connected. I can't get more than 29.7 and they are all Gigabyte with Samsung memory. Can anyone please advise what I can do to fix it? My cards are not modified in my BIOS.

I tried and used all the different settings, the only thing that worked for me was to use Polaris Bios Editor 1.7.3 to modify the biography and use the settings that the BIOS editor told me. Now all my cards are running at 31.7, which I think is the maximum for these cards.
