Swedish ASIC miner company kncminer.com

[Phoenix1969]

Sorry people but its kinda easy to shutdown the miner without blowing things up

SSH into your box and then after login you type on the prompt

shutdown -H -P now and see how the machine stops running instant, this will protect it from running full power when turning it off

And yes do never turn on a electrical device instant after you turned it off.
Its a rule to give the components time to unload the power before powering it up again in most cases 15 seconds should do.
Since i close the miner in the proper way i do not believe blowups will happen since you have some time between shutting it down in the control panel and then goto the device to shutdown the psu. I my case thats about 2 minutes.

I had suddenly a die 0 problem and one of the asics was starting to turn off more and more cores on a die.
I had some back and forth mailing between knc and me, now they asked me to make a rma.
Just followed the steps and send the failing boards as they requested.
The next day knc reported to have fixed the issues and send them instant back to me
So in very short time the boards are back and hashing away.

KNC has prefectly solved this and fast.

So i am glad i did ask them for help, and instant did the RMA.

People saying it will take long ... NO ITS NOT it was lightning fast

From the horses mouth to my ears.....
Thank you for sharing.

Sooner rather than later electricity costs are going to become very important. 

Absolutely. But when that happens, no one is going to want to pay $13K for a few TH.

The big difference with GPU's, is that highend GPU's would always be relatively expensive compared to the electricity they use. High end GPU's are in demand for gaming etc, regardless of what bitcoin difficulty is. Bitcoin ASICs have no use besides mining, so once mining profitability drops so low that electricity cost becomes a major factor, prices per TH will have to plummet.

Q2 begins in 3 months, 2 weeks.... not seven months... and the ststement said q1/q2, so could be sooner.

KNC have shipped *everything* late. Even, somehow, boards they had in stock   So they have a 100% track record of delivering late. That's what I base my numbers on - what they have done over and over again - 100% of the time.

They say Q2, it could easily mean "first weeks in Q3". That's totally consistent with what they have done 100% of the time so far. If you think they will suddenly change that, when going out into uncharted water's with 20nm, you are welcome to delude yourself into believing that. It's much more realistic to look at what a company have done 100% of the time to work out how they will perform in the future.

Until another company can physically show me a better deal.... They get a facepalm from my wallet.

28nm tech.
KNC = 140GH/s per board
HF = 500+GH/s per board

Those figures suggest massively superior engineering to me. How about you phoenuis? Or are you going to tell me 140GH >>>>>>>> 500GH?

Anything else, and you're delusional.

You call me delusional when you have those figures in front of you I think those knc rose tinted glasses you wear are pinching your brain a little too much. All that "special treatment" you got from knc is clouding your judgement.

and...  "HashFast Announces Fastest Bitcoin Mining Chip in the World!"...  uh huh...

See above - it is! Unless in your rose coloured world 140GH >>>>>>>> 500GH?

Of course it could be 5.5TH and BTC could be at $2K by then, who knows, who knew that KnC's 350GH/s Jupiter would end up at 650GH/s and BTC up from $100 to $1000?

BTC price doesnt enter the equation. Yes, I used dollar pricing, but only because electricity is still billed in dollars and to make it more clear how relatively insignificant 0.1W/GH better efficiency still is and will be for a while. ROI calculations should be done in BTC, and any fluctuation in the price would apply equally to all asic vendors. If anything if BTC price keeps going up, the energy efficiency would become even less important.

As for Neptune being 5.5TH; thats possible, but for BA Im going by nominal specs, they also promise overclockability to 2.1 GHz which would put the X3 at 2.7TH or 5.4 TH for 2 units at the same price as Neptune. NOt too much difference there either, even if Neptune ends up at 5.5TH.

But I've made back what I spent on my Oct batch

When you calculate your ROI in BTC?

I don't calculate ROI in BTC, I don't give a shit about it more than as an exchange mechanism really, if it ROI's in BTC then extra bonus in my books.

My October jupiter cost me cash, I've made more in $ conversion from BTC than it cost me, the Nov one has made its BTC back plus the extra cash, both are still bringing in a BTC ever couple of days and have paid for a Neptune as well.

This is a hobby for me, but a hobby that pays for itself and earns a tidy little sum on the side after paying for my entire electricity bill.

by far knc is the best company
i am one of the first 1-500 that i had sent money to knc


the problem is the be and next year the best company

i think that knc will have again for sell the 28nm miner new year day

[The Avenger]

by far knc is the best company

The only other company that has shipped is bfl, so it's only really fair at this point to say "knc are better than bfl".

I think in the new year, when 2 or 3 more asic companies ship, we'll see a whole new picture emerge.

[jelin1984]

come on bfl is garbage

do not tell me about bfl labs

Okay "knc are better than garbage"

1) The SeaSonic has two PCIe connectors one one cable.  Don't use two on one cable.   You should have 4 connectors plugged into the power supply itself (plus mother board and molex connectors).  That means you will have 8 PCIe connectors use only one from each pair.

That did the trick, thanks. The SeaSonic cable has 6 separate 12V lines coming out of 1 modular connector, which splits into 2 separate PCIe connectors with 3 12V lines each, so I had assumed it would be ok (the 12V lines are not shared). But apparently there is a power limiter in the individual output connectors coming from the PSU.

2nd on D&T recommendation.  I run 12 Nov Jupiters with Seasonic X-1250's (or rebrands) using a single PCI-e power from each 'pair' - and so far so good......

No other company has delivered faster than KNC, and now since others have announced delays longer than the few days KNC was late delivering... So they are already later than KNC.  Waaaaay later than they predicted, I don't see your reasoning. Totally twisted to see what you want, and not the truth. Where are the Terraminers & Baby Jets they "promised" months ago?

They say Q2, it could easily mean "first weeks in Q3". That's totally consistent with what they have done 100% of the time so far.

Right. and they are thousands of percents faster when compared to HF & CT's original delivery dates.

Until another company can physically show me a better deal.... They get a facepalm from my wallet.

28nm tech.
KNC = 140GH/s per board  delivered & hashing ..  3 batches!  and the 20NM Neptunes?
HF = 500+GH/s per board  Not a single unit delivered, and delayed over a month over procuring substrates
CT... Just announced fabout....   How late?

Those figures suggest massively superior engineering to me. Me too! How about you phoenuis? Or are you going to tell me 140GH >>>>>>>> 500GH? Yes, I am... that 140 gh/s was delivered in October... and since has increased by a large margin, delivered 3 batches... and Now the Neptunes are on the way.... Where is HF again?  and CT?

Anything else, and you're delusional.

You call me delusional when you have those figures in front of you I think those knc rose tinted glasses you wear are pinching your brain a little too much. All that "special treatment" you got from knc is clouding your judgement.
Delusional, yes indeed. Hahahaha. I guess we will see who is more delusional come Neptune time. This is the same stuff we heard all along the dev process with KNC... yet they dominate the current hashrate

and...  "HashFast Announces Fastest Bitcoin Mining Chip in the World!"...  uh huh...

See above - it is! Unless in your rose coloured world 140GH >>>>>>>> 500GH?

It's crazy how different we see things....    Your fact-age is true indeed, yet so is mine. A matter of perspective. Interesting to hear though.

500GH/s per board isn't necessarily superior engineering.  What if your board or chip dies, then you down 500GH/s hashing power till replacement arrives = more lose in BTC
at least with KNC you're only down 140GH/s and other boards still gets you something, to me KNC have superior engineering and also done without water cooling.

come on bfl is garbage

BFL the company and management are garbage, but their miners arn't that bad at all.

I have little single hashing since early august and been hashing flawlessly since.  virtually no HW errors and never rebooted.  just runs and runs.

But, I'm no BFL fan by far.  it took 14 months from payment till shipped. 

[The Avenger]

It's crazy how different we see things....    Interesting to hear though.

To be honest, I haven't been following Hashfast and when they promised to deliver. But seeing the 500GH/s per chip news seems like a massive leap forward.

Toying with the number - they are saying they expect to get more than 500GH/s from these chips as they refine things. So let's say 576GH/s, as it's a number we are all familiar with in this thread. Jupiter per chip.

So you buy 2 Sierra's, 6 chips, that's about 3.5TH. They claim "Orders placed today are guaranteed to ship by March 31, 2014", which I would consider is possible since they now have working chips and ample time to refine. It'll be solid tech, not another round of prototype's like the neptune will be. It's worth extra, in my mind, not to be a guinea pig.

At $6,300x2, that's $12,600 with delivery in Q1. So cheaper and sooner than knc promise neptune.

I'm no fanboi for any company, but doesn't that look the better deal to you phoenix? Obviously you got a massive discount, but for those who are paying the full neptune $13k, it's a good deal no?

[helmax]

I think we should not despise any company
because competition is good for end user
if not have that we were still using the bfl

[ASIC-K]

all hashfast did was just put 4 dies onto one package....i dont see how its so revolutionary. the box is still bigger than knc boxes and way more complex = more to go wrong....

I had considered that, and decided the 3th/s was a minimum number, and compared that to the original Jupiter specs... which ended up nearly double. Then I also considered who has delivered, and who has not. If I had to narrow my choice to a single word explanation, it would be "Experience".  To me, actions speak 100 times louder than words... and so far...words are all we have from HF & CT. Wasn't a hard decision to stay with a proven Company for me. Especially one who treated me so well.

[The Avenger]

KNC also packaged 4 dies into one package - only each die is only pushing out 35GH/s. Whereas hf is pushing 130GH/s ish. That's like 3 times more per die. I didn't say it was "revolutionary", but it's certainly significant numbers.

[ASIC-K]

knc dies are on the same silicon tho, just divided into 4 sectors. hashfast literally took 4 chips and put them on one substrate.... each of those 4 little chips probably has 4 dies its self as well....see what im saying? if knc took 4 of its chips and put them all on one subrate, it would be the same thing, under one heatspreader and heatsink....
