Yeah alot of us have that problem with the lowdifficultyshare. It gets fixed for me after 15 min when the miner reconnect with the pool (dwarfpool). Not sure if a pool issue or a miner issue. Dwarf is doing some changes with their site, maybe their ports too.
okay, I'm seeing some of these lowdifficultyshares also with 9.6, but with 9.7 there are a lot more - can you confirm that 9.6 is doing it's work better?
I reverted to 9.5 and for the past week all rigs have been rock solid. 9.6 and 9.7 with monitoring fail with latest cards. (tested on 30 plus RX470 and RX480 cards)
Edit. I should have mentioned, 9.6 and 9.7 and fairly solid on NON modified bios cards. 9.5 is the most stable for bios modded cards.
