Thanks. I have 39 amd 570 (3 rigs à 13 gpu).
Raised total speed from 1208 to 1213 with phoenix with autotune. Havent tried manually adjusting yet.

The speed was more stable with claymore (1208 mh/s). With phoenix it is from 1210-1213.
And the speed is different from each time the miner restarts due to auto-tune. Maybe it is better to write down the best settings and set the tune manually.
