In Stock Again.
Let me guess not profitable at $400, so it's out of stock. Soon as it's >$450, magically in stock again. It's a miracle!  More than likely is replacing the older s1 units for s2 units, and preparing those for packaging and shipping out. |

2. I had 6 miners in one room on a 20amp breaker and that was the max, over clocking would have yielded less hashrate at that power limit. With unlimited power you can over clock for more hashrate but chips are less efficient. For example another 10% increase in hashrate would need 20-25% more energy, etc. 15% over clock would need 35-40% more energy.
Be careful friend. 6 stock S1s on a 20 amp is too much, in theory at least. I know the 1920 watt is the safe 80% limit of the 2400 watt rating for 20amp but you know there is always wiggle room. Had 3 platinum psus and We specially ran a new connection to the breaker with the correct 12 guage wires not just changing the fuse from 15 to 20. |

As usual, I am not a thermodynamicist, but when I first saw these things I thought, "Damn it, that curve should go the other way." Having said that, wouldn't it be better to flip it, and NOT put plexi on the top? Or possibly, flip it, don't put plexi on the top or bottom, and just rest two fans blowing upward on the new "top" of it?
Did you cut both the yellow and the red cables for the fan? A little hard to put upside down to plug power and ethernet wires when you have multiple units. But I found sideways and stacked on each other space efficient. Well, sure, of course. Do you find that the upper blade runs significantly hotter than the lower? I would assume all that radiant heat rising from the lower blade would make a difference. Do the fans handle it well? No heat problems as they run stock frequency. The stock fans are 125-130 cfm fans, quite stronger than most aftermarket case fans the same size. May I ask why you run stock frequency? 1. It is more efficient to run at that frequency. 2. Less heat, more longevity for the chips. 2. I had 6 miners in one room on a 20amp breaker and that was the max, over clocking would have yielded less hashrate at that power limit.

mine is running steady at 200ghs. Added an extra fan, cut 2 cables per fan, the control cables so they run at 100% Added plexi, turned it upside down. somehow this took away 3°C Running smooth @ 39&40°C  As usual, I am not a thermodynamicist, but when I first saw these things I thought, "Damn it, that curve should go the other way."

Unfortunately KNC ran a perfect SCAM, delivered few machines on time then promised shipping in March/April for the new machines. In the meantime they build a huge farm to compete with their customers (well not really because customers did not get any equipment to compete with) and as their March delivery date conveniently got removed from the site they proclaim that they always meant Q2 or specifically very end of Q2. And since the farm ROIed in about 3-4 months (all using our money BTW), they will gladly refund our interest free loan that we gave them, not ship a single unit and have a $28M farm online all paid for. I guess it was easier to SCAM thousands of people then get a loan from a bank...
It was easier than a bank loan. Especially after the first one for saturns and Jupiters worked. Banks would require collateral or personal guarantee with assets they didnt have in nov-dec 2013. |

 c'mon You forgot to mark the sentence "KNC really is mining to bail out Gox". All I can read is that a group of investors is interested into Gox and offers 1 btc for it. Nowhere it says they will pay for any losses at all. What will happen is: The investors are profiting from all the personal data about you stored in Gox's databases The remaining company funds will be used to pay out what's left - a fraction of your lost BTC. The only money they will invest is to keep up the daily work, to expand the business, develop new features and do some marketing. They will never ever invest from their personal pockets 650.000 BTC to pay out all missing funds. Thinking that KnC as a company, who are not even directly involved in this Investment, are willing to spend 90% of their company profits to pay out your lost Gox coins makes me wonder in what mental state you are. These are separate pockets, even if there's one person coincidently connected to both KnC and Gox. ------ Back to KnCMiner's Big Picture. KnC was founded by miners who where unhappy when they bought mining-hardware themselves, so they wanted to become their own manufacturer (statement from last yrs April or so). Plus banking background and the picture is complete. You make others pay your chip dev, manufacturing house and datorhalls then get rid of them. *) limited batch1+2 and nothing else except a hand full of RMA-boards sold as upgrades (collect necessary fundings, but keep diff low) *) controller boards with 6 ports for a 4 board miner (datacenter was plan A) *) 'keep some coins handy' (do not buy from competition) *) collect big money after implying trustworthiness and competence from Jupiter batch1+2 and put it Q1 for second gen when it never was a real possibility (get more free loans) *) mining against customers, so the customers are competition *) refunding over time some with the profits made from Datorhall which has been built with Neptue preorder money *) announcing an offer forcing the remaining, from an economical point of view, to refund (now they can keep it all themselves, less competition) *) maybe some cash was still missing, so they did a Titan ponzi scheme, at the end there will be no Titan but a refund or conversion to neptune cloud *) offering old hardware (400*18 boards) with 90 day warranty in order to replace it with 20nm tech (seems like dataorhall comes first). They will replace a row of 6 boards with 4 new Neptune boards (Jupiter: 18*400=7200; Neptune: 1200*4=4800). I'm sure the 'soon' delivery means something else than everyone hopes who was going for this option.. now --> next week ---> very soon -----> soon ------> soonish -------> end of time Ex-fkn-actly!! and yet ewik STILL claims that he 'never stops learning' one must ponder what it is he is learning and who it is that will lose out from all this 'learning' KnC&P - i bet you dream of it, dont you phonie? Ur name in lights while your customers all writhe in the agony you and your BFFs have laid upon them... now if only you could snare a ladyfriend with all your dishonesty... what a catch you would be! FAKE promises. Wore thing that can happen is refund customers money and free business loan for research and development and manufacture. And they know not everyone will ask for refund or jupiter conversion which is fall 2013 technology. |

Over the last year the average increase in the difficulty and hash rate was 23.92% per adjustment period and the average length of each adjustment period was 11.38 days. Assuming the network growth rate over the next year is the same as it was this last year we get: Hash Rate Power Energy Cost Cost

What technology jump should allow the xbt to raise with 20% every month? Development of every technology step needs like one year. From 110nm In april 2013 over 55 and 28nm the 20 in June 2014. 14 nm ?? Intel having problems and is not the right deal for 2014. Numbers are highly unrealistic. Fullstop Technology could stop now at 55 to 28 nm. But if they are shipping out 20 to 100k of machines a month thats a lot of hashrate. |

Guys its been at least 2 out of 10 of bitmain that were used (much dust), and also overclocked!
Are they serious? How can they have warranty when they send them o'cked?
Support also sucks, sorry.
Bitmain, any comment on this   Check this guy:  People-Bitmain is using miners for own benefit by "checking" if they work. End of story. Why all miners before your own setup have credentials like: pool-xxx.xxx.xxx
worker- anntminer 123Dont be surprised about any of this fact. Some miners are from 2014 batch and some coming still from 2013??? This means they was mining for them, why you think price is low and they can still deliver units? I stopped to complaint about dust and overcloked units. Whats the point? This is 5 units on sale in UK if anyone interested from me: https://bitcointalk.org/index.php?topic=560828.msg6117056#msg6117056All taxes paid and ready to ship. The pool info is there because they didnt erase it after testing. Every manufacturer should test before shipping out but some actually don't. As to how long they are "tested" who knows. But it's not like they advertising absolutely new guaranteed only turned on to make sure it works units. Knc is same as bfl asm ct etc. NOONE should expect a brand new unit from a major manufacturer. The only time you get a new unit is from a company that doesn't test all units going out. Like some small chinese clone companies. |

http://organofcorti.blogspot.ro/2014/04/april-6th-2014-weekly-hashrate.htmlKNC is my largest concern right now. They now have more than 13% of the network, and they haven't made it easy to find out and track their data. If they want people to be less concerned about them having local control over machines that solved nearly one-seventh of the network blocks during the past week, then they need to be a little more open with their data and their plans.
It makes me more than a little uncomfortable that of the top five block solvers, only one is definitely a pure pool (BTCGuild), and only two of the five provide any public information (GHash.IO and BTCGuild). Going by the fact that ex-wall streeters are involved in KnC, things become a little more clear. (see greed is good above)  They also mine in the dark unknown pools too. In addition to pointing some miners to other pools to spread hashrate around. |

Anyone running 3 S1 on a seasonic? I need help!
I keep getting the psu going into some sort of protection mode...ie no power after running for 10 minutes.
My PCI-E are plugged into the lower right 3 PCI-E slots.
Running 2 units seems ok. PSU is 1250W, 2 units stock, 1 unit OC 375.
There probably isn't enough power on the 12V rail to run 3 S1s. Check the specs of your PSU. I'm running 3 OC'd S1s on a Rosewill 1300 gold and pulling about 1215 watts. Mine is rated at 108A on the 12V rail. > 87% efficiency, up to 92%. M I have a corsair AX1200 that is running on 213V power. It is able to handle 3 antminers tuned to 387.5MHz each. (I tuned one down to 381MHz to slightly lessen the load and because that one unit was just over 1% hw errors) I think it's the 220V that makes the difference. Based on what I'm seeing with my 1300 @ 115V, I don't see how a 1200 would cut it @ 115V. M All of this discussion about the overall wattage of the PSU, line (mains) voltage, PSU efficiency, etc is driving me crazy (and it's a short ride for me). Here is how I see it. PSUs have one or more rails that deliver +12V; the 12V rail(s) has/have a max rated amperage; the 12V rail is the only "part" of the PSU the S1 uses; therefore overall PSU "wattage" is not a limiting factor. If the Ants you connect to a PSU draw more power than the PSU's rated +12V amperage, you will shut down the PSU (best case). We can express "power" in this case as amps since we know we are always talking about a 12V system. Bitmain says the S1 draws "360W from the wall". To give ourselves some headroom / room for error and variability, let's assume a non-overclocked S1 draws 30A (360w / 12V) from the +12V rail. If the BM statement is accurate, you will actually draw less than 30A at the 12V rail(s), but that's OK, we want a margin for error / variability in the amount of power we think the S1 draws. [Note if anyone has actually measured the amps drawn at the 12V rail, we can significantly refine our calculations] Therefore, if you have three non-OC'd S1s on a given PSU, it better have at least a 90A rating on +12V rail. Looking at the BM chip spec and doing a little math, it appears that if an S1 is OC'd to 400MHz it will draw just over 38A. If you are connecting three S1s OC'd to 400MHz, your PSU should be rated at 115A on the 12V rail(s). We may have built in more headroom than necessary (we essentially assumed the PSU is 100% efficient, which is clearly impossible) and you may be able to get away with a PSU with it's 12V amps rated at less than that calculated above, but my sense is that we should keep an adequate margin for variability in the amp draw for a particular Ant at a particular moment in time. == BRAVO |

web interface says shipped
UPS says WHEN the item arrives in their facility (aka SHIPPED), status will be updated...
Hence, NOT actually SHIPPED yet.... just a label created which may or may not be stuck to a box yet.
So weighted and packed up is better than still farming. . . . |

It costs data centers more cost overall than average Joe to run a machine because a slight savings in electrical rate is offset by paying rent for the space.
The bigger advantage is they can run more machines because of more space and power available.
Manufacturers who mine also also have another advantage in that they get their machines at the "real wholesale manufacturing cost".

You cant assume he paid off the hardware because if it cost him $150k to 180k investment im sure he is still losing money, and probably will be a NET negative losing investment with difficulty going up.
With GPU's you can do a decent rig with 3 good video cards for about $1600 that pulls 2500kh (800-900 watts) 4 card rig $2100kh (1050-1200 watts), you do the math on return per kh/$ for the Scrypt.
For BTC the difficulty is much more exponential rise!

While a stock ant pulls like 370-380 through a Platinum PSU. A GOLD is not as efficient and OC ants 10% use 20-25% more energy 18-20% use 35-40-45%+ more energy.. |

1. Bitmain's revenues are in BTC
2. Chips/equipment bought probably with FIAT
3. The price of BTC took a dive
4. He is in China. Even possible to convert BTC to FIAT anymore?
tldr yes, nothing major changed. can sell btc on many exchanges like btce. Etc. Its what currency to convert and bring it back in. |
