yes if I recall he has dirt cheap power 4.5 cents so if he gets 770 watts for 1350 and 1000 watts for 1550 even though he is using 230 watts for 200gh he may be better off at 1550gh.
I just ran numbers at :
0.045 cents a kwatts
230 watts for 200 gh
diff of 41.27
btc at 223 usd
he will make .29 cents a day more then if he stays at 770 watts and 1350gh
That's exactly what I'm tuning for right now. I'm going to let it eat tonight and play with it tomorrow when I have more time to dedicate to it.
