Rx 570 4gb Raven mining :)

hi guys 🙂

i hope you are all doing good.

i just wanted to ask:

1) is it better to mine with stock rx 570 bios? or the eth moded bios? (so far my rx 570s are moded for eth)

2) what are the best values of core clock mem clock and voltage to do this?

3) whats a good miner for windows?

​

thanks 🙂
