In what world would you expect a company with a few hundred dollar in total revenue to date and looking at, at the very least $100K's in expenses, to pay its shareholders a dividend?

To put that into perspective KNC package is 20.25 cm2 and chip only power consumption is ~160W. That is 7.9 W/cm2. Take a look at how large the heat sink is for KNC boards. HashFast package size is also 20.25 cm2 and chip only power consumption is ~250W. That works out to 12.34 W/cm2. HashFast is using waterblock (water has 20x the thermal conductivity of air) to remove that level of heat.
Thats not entirely fair. You measure the size of a heatspreader, the actual diesize will determine the thermal density and for KnC's sake, I hope thats no where near 1000mm˛. Moreover, the entire surface of these asics will generate about the same amount of heat per mm˛ very uniformly . On a modern cpu, something like 90% of the power is used by the cpu core which in most cases occupies only a small fraction of the die (the rest is cache, memory controller, etc). Im too lazy too look up numbers, but Im pretty sure a highend cpu will have a far higher thermal density at its core than any of these asics. Silicon has fairly good thermal conductivity, mitigating the problem for cpu's to some extend, but its no were as good as copper or even aluminum. So thermal density isnt going to be problem with these chips. Of course you still need to get rid of 100's of watts of power, no doubt that requires a serious cooler, but the size of the chips wont make a lot of difference. |

uhh, silkroad was a huge part of BTC economy.. its not just the bitcoins that will be dumped, its the impact on the btc economy itself..
It wont take long for several other darknet marketplaces to fill that vacuum. |

So KNC is shipping, my estimate of 245MM suddenly is to low?  That is so. Bater make it around 320M once everyone who got their 570GH/s units shipped today, will receive them tomorrow and turn them on... Not a chance. It doesnt look like more than a few dozen of them will be turned on this week. The rest will only arrive next week and then we are so close to the next difficulty that even bringing online a petahash wont make much difference. Nah, this upcoming D change wont be significant. The next one is what Im looking forward to. |

We're working on that actually, shareholder reps or something... Either way our goal is just to make sure Sam stays on track, speed up the pace and give him help where ever needed.
The only help you could realistically give is a false sense of legitimacy. Or yeah, photoshopping services |

I think its a fantastic idea, this committee thing.
Really, lets get some kids who havent got the faintest idea about semiconductor product development challenges, not a clue about the status of the project, the financials, who dont even know the players behind labcoin are, where they are or what they do, and for the most part only care about the next dividend, lets put some of those folks on a committee and all will be well. After all, another degree of separation, beyond just the investors > anonymous swede > mysterous sam > fabrizio > scammer can only be good, no? It will do wonders deflecting from the real questions!

This obsession about fresh clothes can only be explained by a need for fresh.. underwear. I guess it was scary at times, right, orama ?  |

Bitcoin mining as lottery would be a sucker's game.
The risk of getting your block orphaned when solo mining is just too high (much higher than satoshi dice house advantage)
Why does that even matter? Even if 90% of all blocks would be orphaned (for everyone), how does that change anything? Just calculate the odds and revenue of finding a valid block and compare it to the running costs. |

the scam is to have a badly run company.

Found a decent reference point to get an idea of the cost of the PCB: From Mercury Research in 2011:  Now keep in mind that videocard PCBs are notoriously complex, requiring many layers and very tight timings (high clocked ram), and yet even the highest end ones dont add more than $8 to the BOM, or $15 or so if you include passive components, connectors and the like. |

"...and there's a worthwhile reason for pulling an allnighter.  " Curious about that I will say that the guy in that video packaging that miner hasnt packaged a lot yet. Im sure he will get better at it in the coming week |

How the hell are they going to deal with the cooling needs if these are supposed to be packed next to each other in PCI-E slots?
As always, they will just redesign the board, then the cooler, then chip and ultimately come up with a different form factor. Dont worry, they will have it figured out by 2015. |

Thanks for your inputs. That is exactly what I was thinking however this is just an assumption. Does somebody in here have experience with the heat sinks/coolers KNC are using?
Its an artic freezer A30: http://www.arctic.ac/en/p/cooling/cpu/473/freezer-a30.htmlIts fair to assume that 99% of users with experience with that cooler have it mounted horizontally, like you intend to do.. Cant remember the last time I saw an enthusiast grade desktop with the motherboard horizontally. edit: the mounting would be the real issue as pointed out in the post above. I havent seen a close up of how the PCB and cooler are mounted, so I wont comment on that. Cooling wise its not going to be a problem, your only worry be structural. |

Any opinions on whether it is OK to place the miner on the side (standing up like a desktop PC) instead of lying down flat?
Would this put the fans under extra stress? Or maybe other bad things could happen?
I dont see the problem, assuming the heatsink/fan is mounted properly. That heatpipes would be less effective is a non issue IMO. Just look at your graphics card, the cooler is upside down. |

here it's me writing, but using the name of the nominee director that I hired for the Honk Kong company He didn't say that he's using the name of an imaginary director. He said he HIRED a director and is using his name. Big difference. Its only a difference if that person actually exists. My guess is that he does, and is called Armandi. Anyway, why dont some of you with vested interest in this scam pool a few BTC and hire a lawyer, there is one on this forum. Just send Fabricationio a nice registered letter asking some clarifications. |

We seem to have a different outcome in Bitcoin... with people racing to the lowest variance possible even with rather high fees to get there.
I've understood this to be at least partially as a result of misunderstandings about mining, since people seem to strongly prefer variances lower than just about any business venture would have anywhere. Do you have a different argument?
I think this may be due to the fact that currently miners are placing bets on future difficulty instead of on finding blocks. Its a different kind of bet, but the same arguments of the OP apply. |

Network speed increase seems to be easing a bit temporarily. Looks like the next D increase may be relatively minor, all things considered:  Of course that will be the proverbial calm before the storm if KnC starts shipping in volume this week. |
|

Maybe you should consider tying your price to difficulty. Or at least to your competitors price/GH/D at the time of shipping.
That will still leave the risk of future D increase with miners, but takes out most of the risk of the D increase during the preorder period.

screw the backlog. those dummies should have paid to upgrade. hard at work!
Do you remember how long it took between seeing their first FPGA board and their single shipping in any meaningful volume? I actually dont, was it a year or so? Do you remember we saw populated 65nm asic boards almost exactly a year ago, and most people are still waiting (and will keep waiting for the rest of the year) ? Going by BFL trackrecord, seeing a PCB picture today, you would be lucky to get a monarch before Christmas 2014 |
