No problem

But i am not sure about their setting. The cgminer only show 8/256
At 0:47, watch in 720p full screen, and you can see SYS_CLOCK=830MHz
But 17A/204W is awesome. I'll be happy with that! That's close to 1GH/W

Yeah heve in mind that a few amps are for the powerful fans which you gonna replace. You are getting there:)
