maybe something like (using 8+7):
1244   937   1900   900  (965 h/s, 113 W) (really stable power draw compared to the other settings which have +5 +10 W peaks)
or
1100 912    1900 900 (865 h/s, 101 W)

still figuring stuff out, but higher mem clocks dont show a gain, or cause a drop, and voltage is important, if the hash stops, increase it by 25 or 12 and try again.

As mentioned above a little higher voltage needed than for say SRB, which I was running at:
1175   812   1750   800 (833 h/s, 92 W)

Its a 'bad' card based on previous xmr-stak and SRB results, compared to the other cards I have.
