I asked before if you used prebuilt miners or compiled yourself. Neither gminer no nbminer are open
source so that was an incorrect answer. Everything after that was based on bad info.
man and I told you what does it do!?
And yes i have myself compiled ccminer and aro miner, drop are more or less same
Its not miner efficiency of the miner is insane drop clock to 500-600mhz at P2 state which should not happen
