Well with old settings (TDP 70% core 90+ memory +500) using -strap 4 zotac 1080Ti got only 43.5mh/sec with ethash algo, i had around 48-49mh/sec before, so best to put memory at 0, in this case hashrate increased to 46.5mh/sec, i think it is something to do with latest DAG changes, anyway i get 195.5 mh/sec with 4X1080+1080Ti from my rig, with memory +500 and -100 core TDP 70%, with pill i got only around 185mh/sec before, -strap 4 is most stable for my rig, no restarts at all, 4-5% stale shares
