What chance solo now? For say one 280x card? How many hours/block? Any tips in solo mining settings? Like scantime?
About POOLS currently existing.
THEY 90% WORKS!
JUST under DDOS they disable statistics. Yes, this nervous thing, but mining works and rewards calculated and payed later even with 10 hours freeze. Run into it 3 times already.
I think, scan time not as important now, since the diff has gone up. That is more important at the start i think. Although not 100% sure about it.
However 1 x 280x will take some time to get a block for sure.
Did you try j doriens pool? did it have the same disconnecting issues? is it getting ddos?
