Tested on Linux today (fresh install).
- RX 580: 3.2 MH/s
- RX 470: 2.5 MH/s
I am sure I could do better but I have no experience with overclocking under Linux. My rigs are Win 10, so eagerly awaiting the Windows version.
The miner worked without flaws, but I did not test for extended periods of time.
Out of interest, what are these cards achieving with SGminer? I haven't tried myself, I'm usually quite reluctant to experiment with my AMD rigs are they are my very stable cash cows mining ETH...
