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.
sorry to drop in
i have 380, 470, 480, 570, 580 4&8 MB cards and never had to relaunch srb 5-10 times, it always made 1 .srb file for each of cards, i see people say it creates a .srb file on every launch, what version does that?
stability is also good, never got freeze or lockups, i am running it on windows 10 x64 v1703 with blockchain drivers :
