what's your hashrate?
Right around 200G (50G per board) on the BBFs. They have been very stable, running off a raspberry pi.
Burnin has done a great job with all the hardware he has put together. Business dealings have been stressed but the actual hardware seems quite good.
I knew that raising the voltage makes your consumption go up exponentially, but this seems a lot. Have you measured your consumption at default speed/voltage? If i'm not mistaken it should be 256 with 900mV, but don't take my word on that.
No, that's right, I have 8 boards and it draws exactly 800 watts.
