Hm? I'm not that negative, as far as I can tell a lot of people are perfectly happy with them. When I communicated with them they couldn't keep a consistent story and it made we wary, but I'm glad other people are happy with them. I'm personally not all that happy with any of the major hardware companies right now, I'm concerned that their business practices have not been doing the ecosystem well, but thats neither here nor there and KNC is certainly not the worst of it.
I agree KnC can certainly improve the speed and quality of their communication. However, their support is still light year ahead of Avalon and BFL. The current state of ASIC hardware companies are all primarily community driven and depend on us within the community to support each other. I don't see that changing any time soon with the accelerated speed of development, the people with the most knowledge about the products will be those who own and run it since Day 1. KnC did handled my RMA pretty well, paid for express shipping both ways and 5 days turnaround from the time the bad board going out to receiving the replacement board.
versus 1W/Gh for KnC (Oct Batch pre-0.98 firmware)
Go update the
mining hardware comparison as it's claiming 2.5w/Gh, if thats wrong then I retract my whining.
That website made a mathematical error. They listed the Jupiter as using 600W and Hash at 500,000 Mhash/s, so the Mhash/J should be 500,000/600 = 833 (or 1.2W/Gh), but the Mhash/J figure was incorrectly listed as 400Mhash/J or 2.5W/Gh. On my old Oct batch Jupiter with firmware 0.96 and all 4 ASIC with 8 VRM, I was hashing at 550Gh/s while using 545 Watts on the wall with a Seasonic 80Plus Platinum PSU, which is around 1 W/Gh. I understand newly redesigned Nov batch KnC ASIC boards are more power hungry but also hash faster at a cost to the efficiency. The actual figure is still way less than 2W/Gh.
