Hi all, new around these parts... So I started mining DRK yesterdays and I'm loving it. Got my rig to run 10,35mH/s @ 675w yeee-ha! Not bad. 2,07mh/s per card. But I wanted to play around with some setting to see if I could squeeze a little more/less juice depending on results. Thing is, some commands work, but I find intensity is locked to 13, power tune does not budge, shaders, gpu-engine... nothing. Once in a while when I restart the miner, it lowers the hash rate slightly, yet consumes less 50w and runs cooler. Using CGwatcher to monitor sgminer. Any ideas?
