Very simplified, and based only on my understanding of others' posts - in a string design the BitFury chips are effectively put in series where it concerns power and I/O, meaning you don't have to drop the supplied voltage as much, and require less control circuitry, than if you tried to put them in parallel.
See also this hackery: "How to chain NF2s together and access them by one USB interface?"
Aight, thanks.

You might be thinking of this:

Note that this does not include the BitFury chip.

By just experimenting with various heatsinks I got this (still using the somewhat crappy USB hub that provides 4.5V) :

This is with Gen2 chips. Gen1 seem to max at around 10-11GH (with the same setup).

Shiny!  Can probably push out a little bit more with a better hub - on the other hand, you'd need active cooling? Smiley
