You are getting almost all what you can get from that card. Running 471 sol/s per second I think it is one of the best setups for a 1070 card.
You can try to increase the memory clock to max of +1000 if your cards hold to it but 800 it is a pretty good number. If it crashes when you increase to 1000 go back to 800 and stick to the settings you have found. Also increasing power limit to 90% or 100% can give a little boost in performance but I think you have already are in some of the best settings for your card.
My GIGABYTE G1 1070 does only 432 sol/s on Nicehash and 455 sol/s on EBWF cuda miner with +750 memory and +200 clock. I am going to follow your example and try to make -120 core clock to see if I get any improvement.
Thanks for your reply.
Yes, I've read on some threads that mining zcash requires more memory than core, and they suggested to reduce Core clock and rise Memory clock. I don't know why, but it works
In any case I've saved this setup on Afterburner, so I can switch between coins with the best settings.
--a little edit to my previous post--
the precise settings, for nicehash, are:
Power: 100%
Temp: 83%
CC:+23
MC:+382
This allows me to reach 42.07MH/s
on EBWF cuda miner I go with:
Power: 91%
Temp: 83%
CC: -83
MC: +813
and I get 471sol/s
Fan speed, in both cases is between 20% and 40%.
What I want to do now is to play with power limit, since I believe it can give interesting results.
