Hello all,
I am using Minera with BFGMiner but I have noticed that BFGMiner is not letting me hash at full speed. I only can get 70% of the throughput before getting hardware errors.
Additionally, I have noticed that BFGMiner taking up CPU load up to 3.5 I think there may be a bottleneck somewhere within BFGMiner that is causing this excessive CPU usage.
My Miners are 2 x Zeus Lightning X6. I should be able to hit 84 MHs with both units... as per CGMiner.
Here are some stats
