I have 6x 580 4Gzb mining ETH
Each one gets 12.91 MH/s
Is this normal ?
How can I improve ?
Guess no one has a RX 580
I think it is normal on 4G memory card to mine ETH. DAG file is over 4G now, so it is better to use 8G card.
I used Polaris to tweak the bios and flash it, and use the above settings, I cant go any higher otherwise it becomes unstable.
Hi! Today i finished building my first RIG with rx570 4gb ( for start - later planning to get 8gb cards ). With Polaris tweak what you exactly mean? You flashed gpu with specific BIOS? where I can get it? I have 2xRX570 and they together get lower hashrate then 1 yours 
What hashrate are you getting
