I'm using z-enemy miner 1.28 and mine with GTX 1070 + 200 core + 0 mem latest drivers Version 417.35 - WHQL,Release Date Wed Dec 12, 2018
Power consumption by each card is about 145W with efficiency 0.99 to 0,16 MH/W depending on current algo (on Power target +0)
I have switched power target to -30% and now power consumption is 102W/1GPU and efficiency is from 0.086 to 0.18 and I have seen even 0.24MH/W
The problem is that i can see significant drop in mined coins and my question is what settings do You use and/or recommend if I want to mine as many RVN as I can with energy wise settings?
From my experience ,for x16 and x17 more than -10% for power will cause negative effect on your stability and efficiency , so if you have GTX 10xx series , -10% power is best you can use and +200 Core is very good. (Try test and change/increase core clock 1 by 1 .. for example my 1050ti cards working better with +137 and lower on +140)
In other hand , mining Raven coin is a mid/long term investment so if you are looking for faster profit and better selling coins , mine Monero or Ethereum/ETC.
Good luck.
