if someone has managed to get Tube2 version 1.7.1 to Rx 580 8 GB without fail it will be thankful to share settings.with adrenaline 18.6.1 I tried a lot of combinations but for now without success. "heavy_mode": 3,"Fragments": 9999 was the best I got on 7 cards - 8310 h/s on heavy, but one of seven cards did not go away."intensity" : 58. Doc, how do you benchmark the cards when running the program? It is interesting that with the same settings they give different crashes. Have one reached half or some percentage of their power and there are stuck?
