So I have a question for the community here about X11 mining on Darkcoin:
I'm mining with two sapphire R9 290x Tri-X cards. I run SGminer 4.1.0 and use a .bat file to start it and CGwatcher to keep things going.
Usually I set my --gpu-threads value to "2,2" but recently I tried setting it as high as "10,10". When I do this then in SGminer I see my hashrate go up to about 3.5 to 3.7 MH/s per card (from my usual of 2.7). This is awesome, however I start getting boatloads of stale shares. On the dashboard on my pool (lotterymining or coinmine, either one) I see a super low hashrate of like 1.2 to 2.0 MH/s, when it should be up near 7.0 MH/s. Does anyone know why I start getting all these stale shares when I put the threads up?
