Probably a stupid question:
Is anyone's Jupiter actually working reliably at 450+GH/s?
Yes mine, stable at 500 Gh/s @ BTCguild. 0.94 firmware.
Mine too stable around 450 but they better f'n sort the firmware, before 0.94 mine was running 100GH/s faster.
I agree they have many , many issues with their firmware. Kind of unprofessional from this company.
