Let's see what firmware they come up with Monday, because so far I'm far from impressed or satisfied with the product, not to mention the delay for which I still expect compensation.
Don't want to be nagging daily, but it seems that's the only way with KNC.

Jupiter 1 is hashing with 0.98.1(beta) at stable 564GH/s with 0.9% HW erros - no complaints there. The only thing that can be improved is the power consumption, but no big deal for now.

Jupiter 2 is still averaging 420GH/s with 0.98. The beta firmware did not help and it even reduced the hash speed to around 390-400GH/s. I expect improvements there.
