Do BitFury rigs overclock well? Is it reasonable to expect 500 GH? Are they reliable? I read a good number of horror stories on this thread from folks who had a lot of trouble getting all 16 boards to work correctly due to board wobble and poor connections. Does the SD card still get corrupted when the machine is powered off?
Do not expect more than 400. The systems are quite stable, but there is a lot of variance in each card's performance.
