Taken my KNC Neptune refund of £7,000+ UK pounds and Spent less than half on an order for a SP30 (August delivery at 5.4Th/s).

Don't know if Anyone from KNC reads this forum.

KNC were you looking to build customer loyalty, well you failed.

Bye

Why do you think they are holding refunds? Because they are reading the forums and don't want people to join my Group Buy.

Ok, maybe I´m just dump, but please be patient.
I´m reading this topic for a while and was wondering why some people are getting so angry.

I really don´t like the tone of some of you here, just because you are shitting bricks, you can talk normal.
Why are you guys getting so emotional?
You know you shouldn´t play with money you can not afford to lose.
Ok, it maybe sounds like a teacher. Just wanna let you know, I also ordered 3 Neptunes in November with a loan from my Bank.
Nobody forced me, it was my decision. So I can just blame my self.
I understand that KnC is behaving not very nice and customer friendly in some points. We all waiting for infos.
Clearly I would also be angry if I had to wait for weeks until I get my refund, or even an answer.
But until now, this didn´t happen to me with KnC.
Every time I wrote an email, I got an answer and had to wait at latest 2 days for it.
Maybe I´m just lucky?
I´d like to understand, why anybody changed his order to FrankenJup?
Ok, you´ll probably mining next week, but you´ll have 28nm and just 3 month warranty. Never ever would have done that.
Also wouldn´t change my order to Titans. It´s just scrypt, not scrypt-n and I think, we all are pretty sure, that it´ll come to late.

So either stay with Neptunes or refund.
So after all the speculations here, lets stay with the facts. And please correct me, if I´m wrong!

Until the Jupiters, KnC delivered as the one and only european company who builds asics as promised and way better.
Why would they saw off the branch they're sitting on?
They have a good name, they´ll surely try to keep it. They earned money, and yes of course, they want more.
Fine for me, as long as I get, what I paid for and I get it in time.

Who can prove, that this won´t happen? Q1 is over, I know, but they never promised it. Although we all wanted to believe it so desperately.

And please don´t compare AMD or NVIDIA 20nm problems with asics. It´s completely different.

This is mostly irrelevant to Bitcoin mining chips: they are so redundant and fault-tolerant, that they can use just about any technology that has working transistors ("working" in the analog sense of the word).

Fab problems for a top-flight light-house customers are actually moderately good for small, research-like customers doing Bitcoin mining: less competition for the limited wafer-start slots.

One SHA engine is simple, deceptively so, cram so many together on a chip and you get horrendous power and leakage issues that are more like multipipe GPUs than CPUs or SOCs or anything.

If it was sofa king straightforward, every SHA ASIC ever thought of so far would have come in below, even at power target, on time, or even at all. (AM had a fail, BFL had a fail. and don't forget they were working with reputable design and layout houses. And there might have been a couple of private venture flops we've never heard of)

You've got one guy who designed all Samsung top shit failing to get his projected 2Gh out of the cointerras for example. Hashfast approached the SHA ASIC game as "this is going to be a piece of piss" and got their fingers burned off to the shoulder.

Anyway, when you've gone out and made a SHA ASIC that came in on time, with power and frequency within even 30% of the theoretical capabilities of the process, then I'll let you tell me how simple SHA ASICs are to make.

Made 4th request for refund since the 16th without even one response. Account updated to " Refund ready for process (Payed) " but no email to accept banking info or give estimated refund date. I have also given them a BTC wallet address, if they would like to refund that way. Very piss-poor customer service, but they probably fired all the CS to hire more techs for their installs.

KnC == POS

That's strange. They have always responded to me. Sometimes a bit late, but nonetheless given a response (email).

According to UPS, my FrankenJup is due for arrival on Friday. My order status on the KNC website hasn't changed but I received a notice from UPS My Choice late last night.

Why do I think the nightmare is just beginning? Lol.

My greatest fear! So far I've had no delivery problems other than fans that had popped off (KNC) and some loose boards (BitMain) but all of my equipment has worked as promised. I suppose it's my turn to suffer.

i can confirm they are on the way...should have them tomorrow, I have my neck plugs ready for Frankenjup. Grin

This is why I'd rather get the boards, their boxes and fans and carp don't ship well... I'll just put it together myself  Cool

In other news, it seems that KnC's pool addresses are dumping about $300,000.00 a day, sending it somewhere....

You guys that are being offered refunds in BTC, did you pay in BTC?  What does "special circumstances" mean?  If you have been waiting a long time for the cash refund?

This has already been discussed numerous times: only Bitfury used the proper design flow for the mining chip: BSIM (or equivalent analog/mixed-signal) simulation, but this was his first ASIC project. Everyone else used the low-power digital design tools that are emphatically, obviously bad at designing/simulating high-power chips and attempted to saved time by skipping the analog-level design verification.

Thus far all the alleged "top shits" failed to post any substantial technical information. So either they are just CAD monkeys or they knew things are different than promised, but the truth was only available under NDA.

There are many ways (not just leakage) in which immature process could be unsuitable for extraordinary complex chips like OoO CPU or HP GPU, yet sufficient for highly-redundant fault-tolerant designs. My personal SWAG from the available information is that 20nm CMOS processes suffer from random faults and wide spread of parameters so that the transistors aren't really "complementary".

I would so love to see him do a 28nm shrink.

Bitfury can't just shrink his design. He did full-custom 55nm drawn transistors with 65nm nominal process. But at least he was knowledgeable enough to point my mistake that BSIM4 models are not required for his process, BSIM3 are enough.

My best guess is that everyone else (who did unrolled cores) used standard-cell low-power design flow and crude modeling/simulation tools that usually accompany digital synthesis tools.
