It pains me to say it but while the numbers phoenix reports, and its lower fee... I actually do get better numbers with claymore..
I find myself disappointed. because on paper phoenix was streaks ahead, but the numbers at the pool were a good chunk below reported and stales were much higher..
I think cetain pools have worse latncy. Im on suprnova and my stales are very low(.25%) daily avg. over the last few days. Claymore i was getting a solid 1.5 to 2.5% stale using a lower mining intensity. Hash rates were also on avg 1 to .5 mh/s.
all i can recommend have a clean system, fresh installed use latest drivers both mobo and watman or nvidia. I honestly think it will solve alot of these more cryptic code erros and issues people see.
