As you can see, 1060s are obeying clock/power limit, but 1080 does not, leading to regular crashes of this card.
Well I do not influence the clocks of your card at all - I just run a program there, but do not set any clocks or fan speeds nor voltages - nothing. lolMiner does not even read this values, because in OpenCL standard its not designated to do so.
So if your card is not following your power target setting, this is an driver / overclocking tool or cards bios bug, but non of the miner, since it just takes no influence in that.
