Some what off topic but 517 GH/s? I thought it was more like 400 GH/s stock. Did you modify the boards for overclocking?

BFSB sold them as 400 GH/s full kits, but nearly all of them make 500+ GH/s. My boards are unmodified, I will play around with that when they ~~brake even~~ equated the loss I made from the actual ASIC all-stars.

Impressive. It makes me think a 28nm die shrink of Bitfury (Bitfury28) could be <0.5 J/GH at the wall (with high efficiency PSU).

D&T... since both hashfast, cointerra, and a bunch of others are claiming 0.6W/GH/s for non-custom 28nm.. i see no reason why a full custom bitfury can't do better than that... but when will it come? and will any one else supersede it? bitmine also claims full custom (but i doubt it as they did that really quickly!)

Well 0.6 J/GH at the chip isn't <0.5 J/GH at the wall. I honestly could give two craps about the at chip efficiency unless the company selling them is willing to a) pay for all the non-chip power use or b) I was designing my own miner and buying raw chips by the reel. "Full custom" has no standard definition in the industry anymore. So nobody can say their chip isn't "full custom" and it also means absolutely nothing.
