From the two blades I am getting about 13.8 mh/s with an average of about 1.6 h/w errors per hour over the pair of blades, I will be increasing the clock once I've a 24 hour run under my belt, I suspect a combined total 14.5 mh/s maybe possible across the two units.
I am soure you can get more if you change thosw two Q7 and Q8
my replacement ones are on their way.
I hope to tell you it works in a few days
