I have r9 280x mining on dwafpool current hashrate @ 12.5mh mining with claymore dual ethereum is that normal?
or some driver issue?
used to have around 24 using ethminer.

also i have gtx 970, hashrate @ 3.4mh , how to get it back to like 18mh like in ethminer



what are the factor to determine mining hashrate?
server/internet speed/ does it play a part?
