6 RX570 Nitro+ cards Bios Code 43 error



Thanks for your help in advance, I downloaded a bios that initially worked with 5 cards and was giving me 28.5Mh/s however when i installed the 6th card it all went downhill from there. so i reinstalled the original bios in the cards and everything was working fine however every time i install the edited bios to cards they stop working, they seem to also work intermittently so i got two of them to work but when i installed the 3rd one the other two stopped working again.

can you please tell me how i can fix this code 43 error and make my cards work again with updated bios.
