A9 ZMaster after 12 hours:
32605.85 Sol/s
Accepted rate: 73.5% (on NiceHash and nanopool).
PSU fan at 100% all the time making more noise than an airplane (PSU which is totally cold).
With my rigs, accepted rate: 96%.
High failure rate on major pools. The Bitmian Z9 over-clocks in a breeze and this one cant even do its rated hashes. No wonder they need a major giveaway promotion.
