I want to ask if RX480 8gb is better than 570,480 8gb for mining monero, ETH ? I know that 480 needs less power, but has no protection against heet.
Almost no difference.
No, it won't it, you would have to force flash it, but it might not work good anyway.
Is there anything I can do to get one of your modified bios'? Could I send you my original one?
Bit out of time, if you have more RX cards you can buy PBE 2.2 and mod all of them
