So each stick runs are 8GH/s, but can be overclocked to 23 Gh/s?
I should be getting my 53 soon. Depends on your HUB Hub. Cgminer will try to max out to highest it can.
Some get 12gh without doing anything cgminer does that default.
I had the same issue with U2 USB miners. Cgminer ran them 250 default... they are 1.6gh but were running 3gh.
