I don't have AMDs but here it what I have learned so far and you might try the power setting on the AMDs.

So here goes How do you edit the part of the line ( stratum+tcp://bci.suprnova.cc:9166 ) to have add --cuda-block-size 320
to your startup command - just add --cuda-block-size 320 to it
after stratum
last thing on the line

I have 4 GTX 1070, 1 1060 6g and 2 1050tis

so far I have found out

Settings for 1070

power up, core up, mem lower

and add --cuda-block-size 320    - I don't know how to do this, Its all new to me
to your startup command

you will get around 12mh on your 1070
with around 130w

I get 10MHs and want to add the new command  of add --cuda-block-size 320
to your startup command - just add --cuda-block-size 320 to it
after stratum
