Stop to attract to SRB miner. It unstable in hash speed as hell! To get max speed for my 580 cards I relaunch it 5-10 times. Rebuilding kernel bins is also different story...
Claymore's miners are stable as rock! Fast starting, stable speed.
Plus SRB miner slower on old 2xx and 3xx cards.
If people didn't like Claymore's miners they didn't use them.
My impression of Claymore is that i get 100% reject when mining Electroneum, though i'm not sure if Claymore mines it at all, otoh SRBMiner gets 100% accepted. Same card (R9 280x), same settings.
Because Electoneum has been forked to other algo, not v7. Claymore's miner up to v7 algo support.
