As far as "most 1070 can do over 31Mh/s" - I call BULLSHIT on that one, NONE of mine have ever managed more than 30 no matter HOW HARD I pushed clocks, even at 180 watts much less 95.
ETH depends WAY too much on low memory latency, and that VARIES WIDELY depending on the brand and sometimes the specific chips of the memory in a card.
Ok so I dont mine ETH, but i switched and setup my cards just for you. Here is the screenshot of my 7x1070 rig. And please do not talk bullshit to people just because of your extremely low knowledge of the nvidia cards ( judging from your previous posts where you are lost tbh). Just for your knowledge rising TDP will not give you any more MH/s in eth.

What model of cards are those, what settings, how LONG can you run them at those settings without crashing, and what brand of memory?
If the memory is Samsung, THAT is why you're achieving those *BETTER THAN NORMAL* ETH hashrates - most 1070 cards do NOT have Samsung, they have lesser brands like Micron or Hynix which limits their potential STABLE memory overclock a lot and doesn't let them get as high of hashrate as a result.
ONE MODEL does not qualify as "most", even if your cards CAN handle hours at the settings you were using.
I never said ETH was the best option to mine on NVidia - try reading what I posted where I SPECIFICALLY STATED it is very profitable "just LESS so than other options."
