I just ran a bios mod using this method, but did the mod in HiveOS on one Gigabyte RX5700XT Gaming OC and the whole system will not boot with my 6 GPUs plugged in now. I can boot the system with all GPUs unplugged and running off the motherboard, but when I plug my GPUs in, I get black screen and the OS doesn’t boot properly. Any ideas? Se Below on the successful flash.

I get almost the same but slightly different OC than you. My cards are under volt little bit, thus i have lower power consumption.
Powercolor Red Devil 8GB Samsung GDDR6
OC 50 1400 775 910
power consumption per card 97-104 W hash 56.2 - 56.75 MH
Gpu’s can be Dual Bios o r Single Bios, all dual bios has a fisic switch to chance between Bios Chip, but I guess your Gpu is single so that’s why my suggestion.
