32 BEs loaded in 4 10 USB port hubs. 14 stock BE, the rest are overclocked to 448MH/s

are they hardware overclocked or software overclocked? do you have a link to how you did it?
I may have missed a step, but I think that you can't soft overclock them.
I'm going to agree with this based on what I read and heard. As far as I know you can only overclock them by changing stuff in the hardware.
Yep, you have to replace crystal ocillators and such. way above my level
