So I'm undervolting and underclocking the 570 to decrease power draw.
When mining I'm using wattman to change the values and hit apply, I see the number on the power meter at the wall drop with 30-40 watt.
When I pause mining or restart the power goes back up to the same value before. When I make a minor adjustment in wattman (1 millivolt) and hit apply again, it drops 30-40 watt again.
When leaving it like this, I come back after 24h I see the wattage has climbed again with 30-40 watt. I have to hit apply again to drop it.
Anyone know what is going on? Is it a bug somewhere? I'm using the blockchain driver on win 10.
