I think I am not a newbie account, and for the second time I will declare that the drivers are good and working (for me on 570 and 580).

About the hashrate - see the picture of one of my rigs (6x RX 580 8 Red devil): average is constantly improving ad at the moment is even higher then the reported!!! (never seen this before)
