Thank you for the explanation. Does that also mean a 2.58k/3 share takes 2579 times more time to hash, than a 1/3 share or am i not thinking about it right?
I think the difficulty setting stays at 3, i just reacted to the first number, because i thought it meant current diff/set diff. I can see i was wrong about that
My second guess was software, because i don't need to restart the device, i just turn bfgminer off and on again and it's working. I haven't tried other miners yet, used bfg just because i knew it supports my asic. I googled that Cgminer should also work ok, so i'll try that. Thank you!
