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.

Is 0.94 a must for stability or can you apply up to 0.93 for now until they fix the speed issue with 0.94?
