Has anyone else noticed that when you drop the power draw on your cards, it doesn't adjust the Sol/W readings in the miner? I took mine from 85% down to 67% and after a few minutes they were still showing 3.30 Sol/W.
I guess your driver had an error or glitch! that's why dstm kinda frozen?
maybe that's happening because of unstable overclocking settings
try to lower it a little and check how it will be going.
