Our rig is mining at a steady 175Mh/s hashrate on Claymore (that's the hashrate shown on the claymore miner). No GPU error, no internet connection issue, everything is super smooth.
How is it possible that our current effective hashrate as shown on ethermine is ... over 200Mh/s

? More than 25Mh/s than our actual hashrate shown on Claymore.
