So I am starting up a new rig with two cards;
1. Sapphire Nitro+ rx 580 8gb
2. Powercolor Red Devil rx 580 8gb
The sapphire nitro+ was easy to work with and I managed to get up to 31.9 hashrate but with powercolor red devil I only managed to get 27.3 mh/s.
The main thing that made difference was the rx 580 drivers. I had to make sure I am using 2017/08/08 drivers and not the updated one. I copied the 1:1750 to 1:2000 and 2:1750 to 2:2000 etc but it didn't improve much. I am also using msi afterburner but it won't budge powercolor hashrate.
Any suggestions please?
