From initial testings with the slow ASICs we currently have, we see great over clocking potential in the SP20.
The limiting factor is cooling, and we're working to improve it. Experimenting with various enhancements to the heatsinks.
Good hear this. Can you please comment on this:
Why is the SP20 less efficient than the SP35?
I thought they used the same ASICs?
SP20 1100W / 1700 GH/s = 0.65J/GH
SP35 3500W / 6000 GH/s = 0.58J/GH
I'd rather buy the SP20, mainly because I'm hoping it will be quiet enough to use as a heater at home, but it is hard to give up efficiency.
