I can confirm 1070 doing over 1300kH neoscrypt if You don't mind high power consumption.
Just use klaust miner and intensity -i 17.6
My clocks are around 2000Mhz gpu and 4500Mhz vram.
it is funny, but how you managed to accept KalusT miner this ->> 17.6 <<-- intensity??
I'm trying to put in but it does not accept it! only values like 14 15 16 17 kicks in!
what I'm doing wrong here?
