I need advice about pool, at the moment we are mining on coinmine.pl, all online calculators are saying that I should get 6.6 zec a day, but I got only half of it, I'm aware that this is the mater of many factors, but I know that something is wrong, your advice would be much appreciated
dwarfpool.............read my earlier post about it 
I tried every pool out there and zec.suprnova.cc was the only one paying exactly what calculators say. Furthermore ocminer is all the day around here replying to questions and improving his pools, i prefer a pool maintained by a miner than a pool maintained by some guy replying 7 days later (if ever they reply)
@rozsada try the 16.9 drivers. How many watts is your PSU?
@mettalmag yes, dwarfpool is paying me roughly the same as Claymore miner says
@mettalmag yes, dwarfpool is paying me roughly the same as Claymore miner says
you probably mean dwarfpool displays roughly the same hashrate as Claymore miner says? actually it displays 15% - 20% higher hashrate and pays 50% less than what calculators say
