My Single SC finally arrived after so many months of waiting.
Results though are not as expected - it is mining at 54Gh/sec with BFGMiner. I also tried cgminer and results are similar.
Is there any way to tweak it?
Yeah they're official 50Gh/s miners now. You have to take the risk of over clocking it 60GH/s yourself!
