I want to leave a review. I ran into a problem that the OC did not work for me. Rig 13 AMD cards on 3 PSUs of 1000 watts. I turned to support, where they told me that 2 PSU would be enough for me. I did so - as a result, my rig burned out. I bought a new 2 power supply, switched to HiveOS, where in the tech support chat they explained to me that I have a stock BIOS in the cards and 2 PSUs are not enough. They helped flash the cards and set the correct overclock.

I understand you bro. I had a problem with bios(Powercolor 588 with micron MT51J256M32 Red Dragon), he told me to use the Polaris bios editor one-click. As a result, one bios in cards died. (:
