Sapphire Rx580 8Gb Nitro Mod and HiveOS Settings (Samsung ram)

Hello there.

I am new at this forum and mining. Can anybody help me?
I have only one card at this time and I want to get more Hashrate from the Ethereum mining. Can anybody help me?

1.) Which mode is correct for this card?
2.) Which settings are best on HiveOS?

Thanks

Is there any person wants to answer me?
