I just got my 30 GH/sec BFL miner today. You can see in this screen shot the 30 GH/sec as "BAL 0" and the 60 GH/sec one as "BAS 0". The number of hardware errors from the 30 GH/sec is far beyond the amount from the 60 GH/sec.
Is this thing dumping way too many errors, or is the 60 GH/sec one just really good?
