Maybe someone can educate me: at $960 for 760-880 MH/s, wouldn't one be better off by buying 7970s?
Is this worth it because of lower power consumption?
It could be. At full power these boards only draw 45 watts. And you can drive them with a very low watt controller. A 7970 is going to require at least 300 watts with a system. So these board will be cost effective a 6-7 times higher difficulty than the graphics card. Depending on the shape of the difficulty curve between those 2 points, and the exchange rate, you could do very well. Or painfully badly. It's a tough call. It was a lot harder decision at $7 bitcoin and BFL promising ASICS in 2 months. That said, I had a buyer for 20 boards drop out on me, so I still have a few for sale for BTC only |

We need the Bitcoin equivalent of the silver coins and pennies and Bitcoin doesn't look at it will have the capability on it's own.
Bullshit. Or, I could be more polite and state it as "I believe you are mistaken". Please support your statement. Indeed. For someone who failed to ship a bitcoin bitstream you are awfully confident it will work for Litecoin. So much for professionalism from Enterpoint. |

They promised me a product, a worst case delivery date, a refund rule and took my BTC. They missed the product spec, the date and did not pay the requested refund - it is a scam!
In addition they promised to pay 1000 BTC as charity donation if they miss the power goals. They admitted to miss the power goals but there is no sign of a 1000BTC payment as charity donation - it is a scam!
Do you have documentation that your refund has been refused? If so you should open a Scam accusation. |

It really depends upon your definition of a scam.
If I offer you a trip to the moon for $30k that would be an incredible bargain.
If I take 1 million $30k deposits and spend the money trying to build a moon rocket with 4 seats on it, is it a scam?
If I promise that trips will start next week, every week for a year, is it a scam?
If I advertise on google that you can buy your trip to the moon for 30k and overlook telling you that there are 250,000 trips ahead of you is it a scam?

If there isn't a cancelled check from Josh to a suitable, independent and registered charity within 48 hours hasn't he finally earned himself the scammer tag?
It's obvious they have known for a couple weeks they wouldn't hit their performance spec.
So Josh, where's the proof you kept your promise?
BTW, has everyone noticed what a pretty shade of yellow highlighting Josh has these days?
How long do we have to wait for for the scammer tag on Josh? I haven't heard of any 1000BTC donation so far. Someone has to open an accusation thread. And it should be for all of BFL. Josh made the commitment in the name of the company. |

Define local if you can.
A few friends of friends may be interested locally. I meant what part of Canada? |

I am interested - but is there a guide for step by step setup ? If yes, I will place a bid.
Yes, I have been sending out a guide to getting started. |

Will the buyer of the 2 broken fpgas get the bill so that he can contact enterpoint to get a replacement? Will it be possible for a new owner anyway?
You would have to talk with Enterpoint about that. The serial numbers will make it 100% certain to them where the boards came from. |

Entropy can you be a bit more specific? What exactly would happen? Before a fire, that is...
The first thing is a huge heat sink and a really loud fan. That's what we had on p4. If your processor runs too hot, you get diffusion in the various materials that make up the device - this dramatically reduces the working life of the processor due to a range of failure modes. Ask the GPU mining guys how fast that can happen.  In the shorter term resistances rise with temperature, driving power demand up in a negative feedback loop. I would guess that test video was just about the amount of time they could run chips without having the magic smoke come out of some components. I don't know what I would do in BFL's shoes. There isn't enough data to really understand what the situation is. But what they reported is not good in the short term. |

I managed to track down the chart I was talking about above. My calculations put their reported power density right in the middle of the Pentium 4 space. BFL is going to have to completely re-engineer their thermal solution if they can't get the power reduced by at least 30%.  |

Thanks for the answer. 40watt doesnt sound bad. I wonder is this really for the quad-version? I mean these are 4 fpgas in one right?
How can such transaction be made securely? I worked with john as an escrow together already but when will he release the btc? Is it when the buyer has the fpgas in his hands? That would mean a risk to the seller because the buyer could claim he didnt get it or something. So how will this work securely for both sides?
I ship with tracking. 45 W is my typical result. The highest bidder gets the best board, and I work my way down the chain from there. 18 hours left. |

GMaxwell you are clearly biased towards BFL.
Not only do you not banish them to mining speculation where they belong, you hide this thread in Scam Accusations.
You also changed my ad title from:
PSA about Butterfly Labs, what to say?
TO
Buying negative AD space against Butterfly Labs, what to say?
Editing my posting without consultation is akin to censorship.
And don't get me started on how you hid all the original ASIC threads from last year in 'OFF TOPIC'

Pastor Josh hath spoken. I just kid. How will they retrofit another power regulator to 400 machines / day for shipment? I'm not even trolling, I really want to know. A better question would be: How will they sort the good die from bad when Josh says their only test socket didn't work properly. I must say, for a self-claimed Intel " engineer" whos making six figures a year, you're showing a very good use of your time. There are only 2 possibilities: 1) Intel is a sucker and their HR must be run by a clueless son of a motherless goat 2) You're believing that you're an Intel engineer so much, you dont even know its just an imaginary job for your online character. LOL. The truth is a bit in the middle my friend. |

There is something i didn't understand in this thread... Why everybody talks about scam ? What is scammy here ? I don't saw author to force someone to give him his money or something... He said when hardware is ready you can pay and get it so lets just wait some time and see... I think scam is when you pay someone and get nothing...
I also had thoughts about developing ASIC, but still cannot get enough funds to start... So if i have posted thread as an announce i will become scammer ?!?!? I think i didn't get it...
Well, if you showed up with a stack of resumes from your organization that establishes a history of delivering ASIC designs, firmware implementations, board and system level hardware, and sales and marketing, I'd say very interesting. If you show up promising technology that no one but $1B/year companies will be able to purchase until at least 2015, I will call you a scammer. |
