I'm going to have to go back over these instructions-my machine rebooted overnight (with the ATI Blockchain drivers I was getting ~20 & 24Mh out of) and now my local Claymore output says 17/20Mh (for the 390/580, respectively) but Miningpoolhub said 14Mh combined and NiceHash now says 48.82 combined. Is there any way to confirm which is correct? Or should I just presume the Claymore direct stats are what is true?
