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.
Yes, thats an issue with NH to address - I switch back and forth NH and Nanopool - I have around 255kh/s hash pointed NH CN7 and even during high rejects period, 50kh/s can still get 0.01 BTC .... I observed that during the night (US time) has less rejects, compared to daytime -- I think this is probably rental/hash supply and demand for current CN7 coins marketplace -- NH may need to fix their "fast" switching codes IMHO -- and may not be anything to do with CN pointing to the wrong CN7 pool.
