I think you're stressing too much. Even if you miss out - like what you're saying (which I doubt you will), is it such a huge deal to use a USB hub?
Everything I've seen so far implies these need external power, so using a USB hub doesn't get you the same setup. But I'm not stressing at all actually. The selling body parts was a jest. I'm curious as to the answer. It would be cool if they had continued plans to manufacture these, especially if they were on compatible boards. It would make it worth it to get the backplane (mini or not) now by upping my order qty. I guess it boils down to getting the numbers to fill a bulk chip order, I think 3,000 is the minimum. |

I was expecting this, even if they get some units out the door in Nov/Dec, it will be a trickle as Xmas will shut everything down.

+1... I was looking for exactly this.. someone putting more than one bitfury ASIC on a PCB.. good find =D
Most of the people are ordering the 8 chip board, which should give you between 16GH/s with passive cooling, and 20GH/s overclocked with heatsink and fan. The thread has a mixture of group buy and technical discussion. |

the entire thread is BS based on something that never shipped, there would have been nothing wrong with using a hard drive style case except it looks boring
With respect, after all was said and done, we learned that the original form-factor of a USB hard drive was nowhere near the final delivery form-factor, nor would it be possible to dissipate the heat generated in such a chassis. Extrapolate this with the original 1.5TH/s Minirig being broken up into three separate components, and we begin to get a clearer picture of what is in store for customers. You are mixing up the FPGA and ASIC product lines. If you want a real issue with the ASIC spec not the FPGA which this thread is about, then look at the Jalapeno 4.5GH/s spec from last year. The device was designed to run off USB power which only does 2.5watts typically. BFL were quoting for their chips at the time, 1watt per GH/s go figure! |

Today is a high volume day. Biggest volume at BitStamp since more than 5 weeks, but today BitStamp is not far behind Gox. (24k / 29k)
The times they are a changin ...
For Bitstamp it's big, for Gox its puny. More so it only looks at one currency pair, Gox does many. If you add them up bitstamp only does about 1/4-1/3 of the Gox weekly volume. |

The picture is irrelevant, I could easily build a working miner in an external HD case, if it is one as you cant tell the size, HD case has USB and power sockets already. The point is that BFL never shipped that case, the selected a better looking cube case, the entire thread is BS based on something that never shipped, there would have been nothing wrong with using a hard drive style case except it looks boring. I see no point to this thread whatsoever except trolling FUD. It doesn't even belong in the scam section unless that's the motive of the OP. If you check the web archive a few weeks later, that picture is gone, and a pre-order link added so you can actually place an order. |

If you go by pictures, the Jalapeno was supposed to be ~1/2 the height it is currently and the LS/Singles were supposed to use what is now the Jalapeno case. Plans change dude, just cause concept = something that looks like an EXT-HDD and turns out different does not equal scam. Once again, talk about the products that actually shipped, not the "were supposed to be" because you saw a little photo on a shopping cart page. There are plenty of reviews and real photos of what was shipped. The Bitforce Single was not a Jalapeno, it was an FPGA miner, it was not shipped in a hard drive case, it was shipped in an appropriate cube shaped black case similar to, but not identical to, what we now call a Jalapeno 5GH/s ASIC miner. |

I think thats a bit expensive to be honest. If you are making a large quantity I would have thought $10-15 might be more reasonable if it doesn't come with any components..
You don't have to buy it, you can always go without. |

I am telling you your picture has nothing to do with the unit that shipped. For all I know it could have been a place holder pic used by the web developer. You are grasping at straws. Look at the unit that actually shipped instead of pushing FUD like a troll. There is not even a link to order on that page! |

Nonsense, you still need to get the heat out of the water, that requires energy spent on fans and pumps, water is only more efficient if the pumps + fans use less power than air cooling fans. With a large radiator you can use larger, slower, lower wattage fans... ...which is a problem created in the first place by the choice of concentrating 250W of heat on a single socket, requiring high airflow over a relatively small space. If Hashfast had designed 4 x 63W chips as I suggested, there would be 4 heatsinks occupying a larger space, hence allowing the use of larger, slower, lower-wattage fans. I thought the Hashfast was 350watts, only 250watts when you under clock it? It's a bit hard to tell from the specs on their site. |

Who buys watercooling gear from newegg? Sounds like someone who has never watercooled anything. Each of KNC chips is rated at 250W. So either 250W can't be cooled with air (in which case KNC is screwed) or HF could just as easily cool their 250W chip with air. So why choose water. Simple water has 16x the thermal conductivity of air. You can cool a large wattage device more effectively and quieter using water. By "commodity" I assumed they meant "off the shelf". Since it has the package size roughly that of a CPU it will work with any waterblock designed for a CPU. Case, fans, radiator, power supply it is all commodity gear. The only parts which are unique to HF are the ASIC boards and controller board. Now compare that to BFL cooling and power solution. Think there is even a single vendor selling an air or water cooler for a BFL single? My hope is in their next batch they allow DIY kits. Sell me three ASIC boards and a controller board and let me build my own.  Nonsense, you still need to get the heat out of the water, that requires energy spent on fans and pumps, water is only more efficient if the pumps + fans use less power than air cooling fans. |

KNC chip die size at 900mm2?!!! There are some numbers for comparison: Nvidia's mammoth Geforce Titan GK110 chip size is at 550mm2, AMD's flagship Radeon 7970 Tahiti chip size is at 350mm2. There is something wrong. Where is the proof of that 900mm2 claim? from KNC's diagram showing the chip has a 41.2mm x 41.2mm lid. Hashfast made a estimation of 30mm x 30mm size die. Just like I thought, you have no actual facts about the die size, you are going on guesses from a competitor. Nothing to see here.....move along. |

When did they lower the wthdrawal fee ? I withdraw some LTC less than a week ago and then it was still the high 0,5 LTC fee.
If you follow their tweets which are also on the main page of their site when it is up, you will see that the fees changed on Aug 18 https://twitter.com/btcecomTwitter can suck the same herpe-covered dick as gox and then move on to a line of a hundred AIDS patients. I can't imagine that there is not one person in the BTC community who speaks both russian and english and would help those twats at btc-e get their shit together and communicate with their customers. The same could be said about your post and you not translating it into all the languages supported on this forum including Russian. I can't help it if you are too lazy to use Google Translate, takes like 20 secs. |

The guy arguing is making wild assumptions about the KNCminer chip with few hard facts, so you can pretty much ignore the post and save your popcorn until both units are shipping. Then they can start to debate the technical merits. |

last tweet "Update is not yet completed the start of the Exchange with ~ 01:00 MSK # btce" MSK = UTC+4 01:00 - 4 = 21:00 UTC --- In Soviet Russia, the site downs you. |

Approximate maintenance end time is 23 MSK
MSK = UTC+4
23 - 4 = 19:00 UTC
So they are late.
