Thats cruel and cold them shipping < 100% working miners,
of the few they manage to ship...
Welcome to 14 months ago when they shipped the die 0 crocks
kfc have always and still do the bare minimum to fulfil their obligations and then endlessly promise firmware updates that will cure everything. Nothing has changed in 14 months, only a few more people have seen through them.
For giggles:

"We only know that a customer's claim for compensation and threatened legal action.
KNC Miners attitude is that this customer demands and threats are unfounded. We handle general requirements of our customers according to established procedures at the pace they alleged and act now as before in accordance with the conditions we have agreed with our customers. We comment in general, not rumors, competitors or alleged / current / potential legal process, "writes KNC Miners marketing and PR director in the mail.
So stop complaining everyone - you agreed with kfc they could ship you faulty/barely safe/functioning hardware
Where did you get this quote Avenger?
The clown acts publicly as if there is only a single customer with a single legal issue involved.
There are some 28nm folks that got shafted by their ineptitude at execution.
Someone @ kfc determined that shipping miners with fans held in place with twist ties, suitable for bread bags not international shipping was a good idea.
All 20nm CA batch customers know by now sammy &Co. put sand in the vaseline.
IMneverHO (<<--notice the huge disclaimer)
I think the whole current situation boils down to 2 very poor decisions by knc management.
First was bonus miners to stem the bleeding from Nep refunds.
This decision committed them to needing 33% more ASICs for 'remaining' CA customers.
I think their mouth wrote a check their ass can't cash.
Second was 5 ASIC per Nep instead of 4.
This decision committed them to needing an ADDITIONAL 25% more ASICs
They could have redone the PCB to include 12 DC/DC instead of 8.
But then they would 'loose face' with their power claims.
The difference is
4 ASIC and 48 DC/DC.
vs
5 ASIC and 40 DC/DC.
If ASIC were as common as DC/DC converters the decision would just be a matter of cost.
If an ASIC cost less than 8 DC/DC converters, it favors the 5 ASIC design.
I can buy 8 DC/DC converters for under USD$ 200 without a volume discount BTW.
The problem with this whole idea is that ASIC are NOT common.
As a matter of fact they are almost as rare as unobtainium.
Add the fact that their value to the customer RAPIDLY decreases over time.
I don't often 'should' on folks but...
knc SHOULD have done the original PCB artwork for 12 DC/DC converters.
This would cost no more per unpopulated PCB.
knc SHOULD have placed 2 power connectors on each PCB.
(cost more for 6 additional holes drilled and via's installed per PCB. (a few cents per)
Their original Oct 28nm PCBs WERE laid out for 2 PCIe power connectors for fucks sake,
it's not like the concept is foreign to them.
knc's whole relationship/life with DC/DC converter implimentation should accompany them to their approaching grave.
A large percentage of their software changes have been DC/DC related.
They have referred to the issues as 'ghosts' demonstrating their understanding of the root cause.
They continue to have issues with sleeping(can be ressurected) DC/DC converters.
Every block we roll the dice on dropping a die from a sleeper.
Then we loose 100% for a minute or so as the whole thing recovers.
It's been 6 months since 20nm launch.
It's been 6 months since knc determined actual yield.
They know WTF their obligation to customers is/was and have come up short.
The fab HAS tapeout already, couple months to make more wafers.
They did it 3 times now 28nmBTC, 20nmBTC, and whatever the Tit is.
My final bitch 'this post' is clocks.
KnC set the bar for customer expectations with their 28nm product.
They did not go out of their way to obfuscate clock settings.
knc DID NOT DELIVER minimum expectations for this customer re 20nm.
With the 20nm product they INTENTIONALLY artifically limit customer clock settings.
We KNOW the 20nm code is intended for optimization/maximization of clocks on the fly.
I'm left thinking they reserve this extra 'x' % improvement to skim off of in house product.
There are ways to get more out of each customers ASIC.
They have been in place the whole time.
The window for a few % making a difference closed 1-2 diffs after launch.
The OC rule for BTC is early on matters, later not so much.
Why would they do this?
See DC/DC quips above^^^
The fuckin things are on the verge of flames now with the single point of entry for power.
If their earlier claimes of safety are true...
The "Y" cables should come with some extra clocks.
knc brought a win/loose game to a win/win situation.
It's no suprise that the customers that end up loosing are now playing a loose/loose game.
Their cash flow situation 'appears' to be extreeme.
Why else would they bleed their customers refund cash for 6 months?
(knc appologists feel free to correct with accurate count of MONTHS the last guy waited)
I doubt they have the cash to even SHIP the bonus miners.
Add the fact that many in 'destination tax situations' will refuse shipment as they will be worth less that the tax owed.
I don't care if the cause is ineptitude or evil, the result is the same for the customer.
They might claim there is only one guy with a single issue.
I counterclaim they have not produced a single satisfied 20nm HW customer.
Not one!
YMMV
