So if I follow your chart right I can do ~450 GH/s at 240 watts with this? What firmware version do I need to be running?
Take a second look. I took 380 Watt for 450 GH/s. I am using latest software from bitmain ( from 19.12.2014 ) It seems to be more stable about constant hashrate.
Did you change the voltage? Seems like most people are getting it to work, so I'm assuming you're doing something wrong.
