Hey Penny, one of my rigs is running the 570 Nitro+'s as well, here's what I learned.
1200 core is the sweet spot on these, looks like you've found it!
Use GPU-Z to check ASIC quality of each card, it is very tightly correlated to how well they'll undervolt. The cards that I have that are ~79% ASIC quality run 836mV at 1200, ~75% runs ~880mV, etc, but I also got a crappy 67% one that wont undervolt at 1200 at all lol, its running 1150 at 930mV

Hi Apneal.
You are right, 1200 core seems to be the best option, more doesn't change hash rate much, but lower clocks do tend to take some away.
Also, thanks for your voltage data, gonna try to lower it even further
Any idea how to get memory voltage lower? Its working on my 480 series, but i cant do it on 570. Didn't try wattool, coz i dont realy like it.
