https://anorak.tech/c/downloads/sapphire they have lots of modded BIOS
The last one here in my case: https://anorak.tech/t/sapphire-rx-580-pulse/5016https://mining.help/ great guide how to mod BIOS for yourself and overlock/undervolt
Thanks. I think I'll feel better modifying my own BIOS than installing a pre-made one.Provided all 5 cards have the same memory (I'll check with GPU-Z), can I modify one BIOS and flash it to all cards?
Yes, you can modify 1 bios and flash it to other cards
Everything should be fine, but there will be some +/- varriance in voltage settings
