What is the lowest stable voltage that you guys are using for mining Eth (or XMR)? I have lowered it down to 1.0 (1.17 originally) so far but I haven't tried to go below that yet.
I am mining XMR with 855mV @ 1575 cclk/ 960 mclk
You should be able to get at least an extra 100+h/s by bumping your mclock to 1200 - doesn't seem to change power use or heat significantly. Or maybe even better by unlocking your mclock w/ ppt and getting to 1250ish (i've been too lazy so far.)
