Meanwhile, the AMD farm is full on with cryptonite7 (NH and Nanopool/Monero) - profitability is outstanding. Low power too, so am very happy here.
Do you get bunches of rejected shares on NH with CN7 algo? I have to switch to Nanopool completely because of the problem. Some people report that old CN algo workloads that are submitted to CN7 NH pool cause the problem but NH do not want to address the problem.
