Sam Cole are you listening, if you want to clean up your dignity now is your change, otherwise you are proving us that you have no dignity, it is not because  I  say it, it is your actions that define you.


This has already been proven and it will remain like this. Cheap Sam Cole will never turn towards the customers that helped him to be where he is today. KnC deserves to die just like Avalon did and it's time to move away from this company and from it's lying and deceiving managers.

fully agree.

Finaly managed to get 3 boxes working out of the batch I had and now seem to find the following issues:

Lots of errors like
 [2014-06-25 06:49:08] KnC: 3.0.310 Failed to setwork (19)
 [2014-06-25 06:49:08] KnC: 3.0.311 Failed to setwork (19)
 [2014-06-25 06:49:08] KnC: 3.0.312 Failed to setwork (19)
 [2014-06-25 06:49:08] KnC: 3.0.313 Failed to setwork (19)
 [2014-06-25 06:49:08] KnC: 3.0.314 Failed to setwork (19)
 [2014-06-25 06:49:08] KnC: 3.0.315 Failed to setwork (19)
 [2014-06-25 06:49:08] KnC: 3.0.316 Failed to setwork (19)

And hashrate drops to almost 400Ghash when running into a lot of hardware errors.


This "failed to setwork" is caused by the "Advanced window", as soon as you click to another webpage (for instance "Status") the error will disappear... and yes: these errors take about 300 Ghs away from the total of 3.3Th (5 boxes).

actually: you get the best results, by not using the Web-interface at all....

I already emailed KnC, but they have not replied... so maybe someone else (You?) should inform them as well... so they can solve this "failed to setwork" soon.

Your whole answer is based on the premise of maximising fiat....
I want to maximise bitcoin
Therefore i ask again
Why buy a machine for 8.5 bitcoins that will likely never return 5 bitcoin (and thats before you take power/hosting costs into account)

Sure, but for the moment bitcoin can't function alone without a link to the fiat no matter how you use it. Unless you just want to horde bitcoins and do nothing with them for at least 5-10 years you must take note of the fiat part. Even when bitcoin will not be linked directly to fiat it will still be linked to products or services which at some point translate into some kind of fiat. I see no problem in just buying bitcoins, but I am sure that you will spend them sometime because you are not part of the top 500 Forbes to afford buying/hording bitcoins and forgetting about them (like most 2009-early 2011 miners did)

iCEBREAKER is a troll! He and cypherdoc helped HashFast scam 50 Million $ from its customers !

Got three people saying they have faulty rigs here, so "functional" is yet to be proved:
http://forum.kncminer.com/forum/main-category/hardware/47688-neptune-here-but-not-working


The link you posted seems to indicate an issue with power supplies not ASIC's.
Your statement that they claim 'faulty rigs' is not supported by your link.
Although the issues are related.

YMMV
Smiley

Don't blame it on sunshine
Don't blame it on moonlight
Don't blame it on knc asic's (or minimal testing)
Blame it on the PSU-eeeyyyyy!

 Cheesy

Is this going to be another "Don't use Corsair HX850, it's faulty and it destroy's our high quality ASIC's" storyline like last year? Because we all know knc do much more testing on their rigs than Corsair do on their PSUs. KNC must have spent a full 48 hours from getting their chips to shipping first unit, so what could go wrong? Those lousy PSU's!

I have to agree with this. The lies they told and then turning the customer into the competition. Shameless and pityful.

Mmmm .... Lurked on this one for a while ... and have respect for Dogie with his excellent teardowns ... but KNC surely lost all trust some time ago?

If not ... why not?
Oh one last thing, I think the bitching about the IRS ruling is idiotic. I mean idiotic in the technical sense because it actually opens up some interesting options. If you have to pay capital gains on Bitcoin then the cost basis for the BTC would be the miner plus the electricity. If you mine less BTC than the USD equivalent of your cost basis you've taken a capital loss, which offsets any capital gains in other areas (such investments in more conventional equities such as stocks).  If you achieve positive ROI then you'd owe taxes at the capital gains rate which should be lower than your income tax rate. Or maybe you try another approach and deduct costs for your "hobby business", which under IRS rules means you can deduct costs up to the amount of revenue the hobby business generated, so you could probably deduct the cost of the miner as an unreimbursed business expense up to the USD-equivalent value of the bitcoins you mined.  Since you'd be getting a deduction against your bracket tax rate rather than the lower capital gains rate, this might work out, and the B2B terms of the sales contract from KNC actually reinforce this if questioned by the IRS - you clearly bought it under a B2B arrangement.  Alternately, it is reasonable to straight line depreciate mining hardware to 0 over a very short period, as they are essentially worthless within a year. One could think of this as an extremely expensive machine tool head that cannot be resharpened.

Be careful what you interrupted the IRS ruling because they can really mean something else, since it's hard to take them to court and win I don't think you want to be going down that path.

Btw, have you found the law in your state that says you have to file tax return each year? When the IRS income tax law was passed close to or over Christmas holidays only a hand of states signed the bill, the fact it was done this way (under the rug) makes it unconstitutional for anyone to pay income tax in the US. And the Supreme Court of the United States ruled that only someone to makes a capital gain from someone else's services has to pay income tax (something to that affect), basically ruling that only company/corporations should be paying income tax not the individual who provides his trade and its reimbursed for it.

The was a movie done on this topic years ago; I thinks it's called Freedom to Fascism.

I guess the big question I have for those who have received their Neptune's in the US and in Canada (if there aren't Canadian's other than myself in this thread) did you have to pay duty if so how how much?

Thanks,



 You don't have to pay duty but you have to pay the HST @ 13% of the declared value after converting to CAD which is a real downer since our dollar plummeted against the USD since last NOV.  I've had to pay this one every miner I've purchased... yes I got BFL'd.
 

depends what province.

Alberta should pay 5% GST only.

*edit* plus probably some kind of brokerage fee

Yikes, so I guess I would like to know if any of the B1 customers are from Canada here and when they get their Neptune what does KNC mark its value as, because that's how they determine the HST. For us Canadians that could mean paying an extra $1500.

LOL, I was'nt claiming issues don't exist, just that the link at the time I read it seemed to indicate PSU's.

Just some friendly pushback from someone who has been known to 'open mouth change feet'

LOL yea of course lets blame the PSU.. which is tested for years of development by Enermax.
Side note which I already told KNC is when I run the Enermax with 2 x Radeon R9 290X the power supply runs stable and power supply doesn't shut down at all, and running these two video cards takes about 800-1100W.
The only reason for tripping the PSU might be that it not actually tripped my PSU's but my bridge PSU tester, so will do my next testing with a simple paperclip solution so the PSU tester don't shuts off the wiring between green and black to make sure.
In any case it's not the PSU's that are at fault here it's the bad design of KNC and their modules.
Even when I run 1 module per 1500W power supply without tripping anything I run into the old DIE issue we have seen with the Jupiters

I will do another endless testing loop tonight because KNC wants me on different PSU then the Enermax so there goes another night in full debugging mode.

Yeah, those Enermax Platimax 1500W 95% efficiency, platinum rated PSU's you are using - not good enough for KNC's hardware! Grin  Roll Eyes  Tongue

Once again, KNC customers become beta testers.

Looking at the manual for the Maxrevo 1500 the OCP is stated as 40-50A per 12V rail.  It is possible to trip the OCP with the available PCIe/EPS modular section alone as it uses only 4 of the 6 available 12V rails.

I would say that at most you could attach 4 boxes from the Neptune to this section of the PSU.  Anymore and it could trip on rails 3 or 5.  Sourcing more power would mean a custom adapter getting the power from rail 1 and or 2 on the MB section.


Finaly managed to get 3 boxes working out of the batch I had and now seem to find the following issues:

Lots of errors like
 [2014-06-25 06:49:08] KnC: 3.0.310 Failed to setwork (19)

And hashrate drops to almost 400Ghash when running into a lot of hardware errors.

 [2014-06-25 06:50:01] KnC: 1.0.344 disabled for 300 seconds due to repeated hardware errors
 [2014-06-25 06:50:01] KnC: 1.0.349 Failed to setwork (99)

Another thing I noticed is that these boxes seriously overload a multirail power supply on startup and causes the power supply to shut down even with enermax 1500W power supplies.
Already send in a report with KNC awaiting their response.
Very unhappy at this point

Nice Smiley It'll be good to see someone with skills break this machine down a bit, so we can see how it's actually running. Loved all your work/knowledge shared in the jupiter overclocking thread.

Yes, with a single rail of 108A it should be difficult to trip the OCP using two PSUs.

Once again, KNC customers become beta testers.

I had odd tripping issues with the AX1200i on my Jupiters, a single rail PSU and I was pulling no more than 1000W but it would trip within a few minutes even once I pulled some cards off of it and tried to run at 500W.

In the end it looks like although they are single rail PSUs the current sensing capabilities (Corsiar Link, etc) internally wouldn't let the PCIe connectors be overdriven..

I started using EVGA PSUs after that, aside from the occasional melted connector it's been good Smiley

Swedish Government has a agency (KO) to help consumers to solve a dispute with a company (http://www.konsumentverket.se/otherlanguages/English/This-is-how-you-apply-for-KO-support-/)

"KO will only support a consumer under certain circumstances. The dispute shall either be significant for the application of the law, i.e. to clarify the legal situation within a certain area, or the dispute shall be of common consumer interest, i.e. concern a great number of consumers. When KO supports a consumer in a dispute, the state covers the consumer’s legal expenses."

For those who are cheated by KnC's "choose one lose the other" plan or who receive defected Neptune, we may file a complaint together. But I am not Swedish, and I do not now how to do this. Anyone can provide advice/suggestions on this?
