~1.08 TH average over several hours on nicehash, 218 clocks, latest stock firmware
1.12 TH average over several hours on multipool.us, 218 clocks, latest stock firmware
1.21 TH average over one hour on multipool.us, 218 clocks, Kano's firmware
CAN NOT use nicehash with Kano's firmware (invalid ntime errors)
As I understood we can run Kano's compiled cgminer under latest stock Bitmain's firmware. We just need some linux geek who has a little free time to try it.

Yeah, 225/6386 thus far (30 minutes in) is giving me about the same hashrate (0.85% increase), and more than double the hardware errors (7.43% vs. 2.33%) ...
What was your value for 'timeout' and where did you get it from?
p.s. by the way I have
asked kano about his (or maybe her?

) plans about new firmware for S2 (or maybe even for S3) and I hope I will not be the one who is ready to donate him for this job...
