This is what I use for solo mining Eth. Dual mining requires a few different steps and uses a lot more power.
50-80 power limit - Set this as low as possible. Don't dip below 1500 core or you'll start to lose hash.
80-90 Temp so you dont throttle too early. I set mine at 85.
1500-1600Mhz core clock
+600-650 Memory for most basic 1070's. Some memory you can push to 900 but I would test each card individually if you want to go that high.
Custom Fan profile or set it to run 60-70% continuously.
Have fun.
Ok thanks, what hashrates do you get with those settings? and you use 1070's as well?
