A fab would have the resources to build like 100 chip binning machine but not even bitfury(guess from their calculations its not worthed...but they are screwing the endusers an retailers this way) itself tests the chips so its unlikely. On a sidenote bitfury chips are cool but a pain to work with, all it takes is a chip to go nuts and it brings the whole chain down. A1 seems kool but they are not so easy to work with.

Its worthed if you have the time, i soldered about 200 chips manually, and about 10 are partial duds and 2 are dead, stopping the whole chain from going. 10 duds is about 25ghs on the negative side if you give them 0.85v + even more on the rev2 chips.
Whats bothering me is why the rev2 chips dont ramp down if they do no work, an h-card with rev1 chips would go to about 8W while the same card would stay at 20W+ if there are rev2 chips on it.
Anyone know?
