Forgot to add. GB discount for 16 chip board is a bit different. 5 for 8 chips and then 2,5 for next 8...

Hi Lucko. This is my first post on the GB page.  This 16 chip option is sounding nice. My thoughts are now turning to power supplies, what size /type of psu would this board need? and does anyone supply a PCIe only unit? (one that will work without needing 24 pin connection) If this board becomes the GB standard I will need 8 more chips. Can you make a guess as to when we need to make this decision? Keith |

Keith 24 pin was used to make things easier in test board...(you have 5 and 3,3 V) Production will have PCIe You will have 8 and 16 chip board... So no need to use 16 if you buy less then 9 chips... For now we are guessing 1:1,5 price and 1:2 size. 8 one PCIe and 110 W and 16 2 PCIe 220W(estimating)... So less then GPUs... I guess that is enough for you to make PSU estimate or you need more data... |

Hi Lucko
So for psu, something like a "OCZ 1000W ZX Series fully modular" with 6 PCIe sockets, would power, 6 boards with 8 chips, or 3 boards with 16 chips.
Would there be enough power remaining to drive a cheap motherboard as a host? or is it better host from another pc.
I also have an android stick pc with BFL software running (I still need a miner to test this) but it looks very low power around 3 watts.

One of the best hosts is in my opinion a Raspberry Pi with Minepeon - have a look at it. Cheap and good  |

I don't know that PSU but I think you have enough power... You are using only 12V and and matherboard doesn't need much of that... |

Is this sale for chips, boards, or both?

Maybe both soon - for the chip-groupbuy look at this thread: https://bitcointalk.org/index.php?topic=238052.0For the board there will be a big update tomorrow. |

Just to let you know... Busy day today... Got it managed to get the board mining. This first chip has not all internal engines available, so it is slower than normal. But it seems some of them will re-activate when increasing core-voltage. I have to experiment with that later... https://www.youtube.com/watch?v=nZIc03dKLIsScope: SPI decoding Left meter: Chip-current in 100 mV per Ampere Right meter: Core voltage I believe we are the first that have a hashing board |

2.3GH/s is good enough for a chip though it's only 10 engine running. what are the estimated price for a board to have 8 mounted chips? Kudos to the first working board  |

I think so yes... If I'm not mistaken theoretical max for that chip is 2.5...
If only 10 engine is not do to power supply we are in 200 to 300 $ range for sure... Maybe less with enough orders... But we will need some more time to look at findings to be sure... And test with more chips...
EDIT: It looks like chips are the problem...

If it's 10 engines running, i will consider that to be a faulty chip. According to BFL website, a grade D chip will have at least 12 engines running. https://products.butterflylabs.com/homepage-subproducts/65nm-asic-bitcoin-mining-chip.htmlBut this is a sample chip and i guess we can't complain much. It still shows how professional are they to send chips that are below grade D.... For my jallyes, I have tried restarting it until i got at least 15 engines running on both chips. It works for me where the engine kinda fluctuate between 13 to 15 engines. Maybe you can try that out. |

For unknown reason topic https://bitcointalk.org/index.php?topic=267649 was locked... Or someone with power hate that we took the lead... So for now I'm waiting to get answer why but it looks like they have changed some polices (see warning next to my PGP key signature) |

Are you referring to the maximum for a 10 engine chip? I thought the typical BFL chips would have more power. |

Yes but it looks like samples are bin chips...

As in substandard shit? I'm not a tech guy. Just trying to interpret the lingo. |

Hi Lucko, you need a COINADO sticker on the cooling fan for the units you fully assemble.
Any more news on the 16 chip design?
