I personally don't care anymore. Gave the whole communication with them to my lawyer and send a monition to them. Next will be a default summons...

Lass' mich wissen, wie es ausgeht. Könnte auch für mich interessant werden. Gerne auch per PM.

i wasnt expecting them to deliver in september, yet they still felt the need to 'make it so'

now their confidence feels less genuine by the day.

their silence speaks volumes

i am very interested to hear what the legal ramifications might be.

i still want answers to my previous questions also.

wow did they say all of that at once, priceless

[aspeer]

What exactly is happening?

You turn on the miner and after lets say 1 min the miner suddenly shuts down? Thats whats happening with one of my miners.

that's bad as i have a small home
no more place to set up more miner

Pretty much. And after it fails its hard to get it back on. I need the reset it several times to get it going.

Try leaving it for like 15 minutes, on a reboot mine takes anywhere from 2 minutes to 20 to come up to a point where I can ping it.

[cognoscente]

Or did some Benghazi rebels have miner problems and were told "No refunds"?

And I apologize for joking about this.   Chris didn't deserve the treatment and death he suffered.  Tyrone Woods and Glen Doherty killed over 60 of the attackers in a running gun battle that took place over a period of many hours.  They were abandoned by our government and their commanding officers - apparently so as not to interfere with a CIA gun running operation that was in progress - providing guns to the very rebels that killed the two Navy Seals.

I'm not sure why people are freaking out, I get responses within 24 hours every time when I make a reasonable, non answered in the FAQ and fully formed request of them. See below:

Hi,
 
We are aware of some performance and stability issues with some of the Jupiter’s and we are working on a fix for these issues. As soon as the fix is released on our website please update your miner and leave it to run for a few hours to check the average hashing speed.
 
If after applying the updated firmware you still have a lower performance we can then arrange an RMA for your miner or board.
 
If you have any further questions please do not hesitate in contacting us.
 
Best regards  | Med vänlig hälsning

EDIT:
Just got a second reply:
Hi,
 
We are in the final stages of testing the latest firmware update and it will be released on our website soon.
 
Please could you try a hard reset of your miner by following the instructions which can be found in our manual available for download here: https://www.kncminer.com/pages/support
 
Apologies for the inconvenience caused, if you have any further questions please do not hesitate in contacting us.

@edgar @ de_ixie

Depends where you are from, in Germany you have §252 BGB equal to §74 United Nations Convention on Contracts for the International Sale of Goods.
You basically have to send them a final notice with you compensation demands, this must be adressed to the company with the complete company name included: KnCMiner AB . If they do not comply send that and your communication with them to a lawyer and wait until the time you gave them runs out (I gave them 2 weeks to comply before taking further steps).
I find it extremely sad that I had to do this since I basically was neutral the whole time, but being lied to on the phone and getting my emails ignored as of now is not the right way to do business.
Keep in mind that if you send that per email you have to have proof of them getting it (reading it).
You shuld send it also a second time per mail or fax so that you have evidence later on.
Also keep in mind that you can only be compensated for the profit up to the point of writing, for further compensation you have to explicitly state that in the letter.

If you are from the US I don't know what the right procedure is.  

IF they do not comply/ignore your email/send you a refund instead:
https://www.online-mahnantrag.de/omahn/Mahnantrag?_ts=5268713-1381500427452&Command=start  this is for Germany only. Fill it out, pay the fees and they will get a default summons from a court near you. (It's damn expensive though, translation costs etc....)

In my books, they have until the end of October to deliver all the October units. October 15th is again an implicit perversion of the "November 15th minus 1 month" assumption.

KnC has explicitly stated that all Sept. / Oct. orders will be shipped by October 15. That was around the same time they stopped accepting refund requests.

There is a shitstorm brewing here.

[RHA]

anybody thinking of making a custom case for psu + saturn things?

Why would you want a custom case when the PSU fits nicely in standard Saturn case?
You can attach the cables inside (just Molex is to be put out a bit of the case)
and the power cable goes through square holes of the case.
Some PSU-s can be aligned to have switch available through a case slot.

[RHA]

does anyone know who KNC chose to do their packaging and assembling?

Do you want to know KnC employees names?

That is not true. They stated that all October orders will be shipped by then. Sept Orders should have been shipped second/third? day of production at the latest.

[merv77]

Have i just killed the Jupiter!?!

Just setup a new miner. Fired it up and recognized that one front-fan didnt work.

I didnt care cause without the case airflow should be OK. I started to change the setting via the webinterface and then the miner suddenly shut down.

I checked everything and found that the front-fan wasnt working cause a blade was STUCK!

So i "unstuck" it and fired the miner up again but NOTHING happens...........  

Whats going on???

UPDATE:

Fan is working normal again.

Situation is like this:

I start the miner and everything is OK, i can access the webinterface and edit things.

After pretty exactly 1 min the miner shuts down abruptly...  

this is PSU fault, i think!

i will try another PSU later

at the moment the miner runs with 3 cards

it doesnt matter which card i deactivate as soon as only 3 cards are applied the miner works

edit: i am using a seasonic 1050 gold

My guess is that (KnC) under specified on the power requirements by saying 860 watts was enough to power a Jupiter.
These Jupiters can easily use more than 1000 watts, probably more like 1200 watts.  Even if then can upgrade firmware to be more efficient, at moment each of the 4 cards on my Jupiter is drawing between 285 watts and 305 watts. In total that's 1150 watts to 1220 watts so in reality you would need minimum 1350 watt power supply, but I would go a 1500 - 1600 watt just to be safe.  Even if they state they could make it more efficient you still need the head room to be safe for testing out past, present and future firmwares.

At moment I can't run all cards at once as my 860 watt power supply over loads and shut down, but I will be more sure hopefully tomorrow after I get another 860 watt power supply to add with the existing one or I may buy a 1500 - 1600 watt to run Jupiter on its own if I can find one tomorrow. 

Again, this is my initial thoughts and I'll know more next couple days as I do more testing.  Also just guessing here but this may explain problems at the data center because if you can remember they bought hundreds of the 860 watt Corsair power supplies and they must be experiencing similar problems.

I don't think it's a huge problem, as all is required is more power and after power problems are worked out then they can focus on driver/software problems to fix hardware errors etc. It wouldn't make sense to do it the other way round.

I'm not sure if the amount of VRM's has anything to do with it, as my cards have 4 VRM's not 8.

[soy]

Could the blown capacitors have been the result of users experimenting, trying to get higher hashrates by unplugging the power supply live from the miner then inserting the live plug?  They might not tell if they did.

Probably multiple workers in hosting.  If due to ease of access a worker(s) did the same and with the same result, could they have kept it secret so as not to look like an idiot(s) before the other workers?

[RHA]

Well, no wonder these things are overheating and bursting into flames!  Lol.  How could someone design this simple case and NOT include exhaust fans.  With all of those heatsink fans blowing air around and causing turbulence, I can't imagine the case is adequately exchanging air.

I understand it's an irony because the case and air at output is quite cold. You can turn off the intake fans and it still works well and stable.
But some people could misinterpret your words and take them literally.

[CYPER]

In line with the general feeling in the topic towards KNC*




*No hard feelings guys, just trying to lighten up the mood a little bit  

[DeathAndTaxes]

A Jupiter can't use 1200W.  The DC regulators are only good for 320A max (and running them at max current 24/7/365 is a good way to destroy them).  So lets assume 80% duty cycle.  320A * 0.75V * 80% = ~200W per board or 800W total.   Throw in another <50W for fan & controller and you are looking at 850W peak.  Note I am not even sure the chip can use or handle that kind of power but even if it could the DC regulators on the board can't provide more than that.

Before buying a second PSU and a 1600W "bonus", have you spend $20 on a kill-a-watt to see what kind of power you are pulling from the wall? If you are pulling 500W from the wall then buying 850W + 1600W to supplement your existing 1600W to power the same sub 500W load is going to do absolutely nothing expect waste money.

[Its About Sharing]

I would imagine that if KNC is sure the problem is in the firmware, they are still running the assembly lines. IF that is the case, then they can probably ship the units quite quickly.

Any word on the production lines still going or ?
