I just had a strange thing with one of my dragons.
Was just checking the days stats on Ghash and 17 hrs ago it scaled down to 800ghs for the last 17hrs ?
Logged onto it and it was running at 800ghs ?
Stopped and restarted and its back to 1.012 th/s as normal..
First time its ever done that..
Could that be caused by a power flucuation ?
experienced this also.. just restart the miner and went back to 1TH.
