Has anyone had any luck getting more than 4 h-boards running on the same m-board? My rig is stable with all boards running at above 25gh/s when I have 4 h-boards. When I add the next 4 h-boards they seem to auto tune down in speed to the point where the output on an 8 h-board rig is no faster than a 4 h-board rig. Anyone have any hints?

What are you seeing when you look at /run/shm/.stat.log? |

Sorry if this has already been mentioned somewhere in this thread or in the long "Bitfury in the U.S." thread:
I was not able to get the starter kit mining against us2.eclipsemc.com
Both the Eclipse status page and the apache status page on the Raspberry Pi showed 0 GH/s
Restarting the miner and/or the stratum proxy did not help.
However, once I started mining against stratum.mining.eligius.st, everything started working and the
starter kit achieves its advertised hash rate of 25 GH/s.
Maybe this note should be put into the first post, if someone else can confirm this issue.
Try port 3333, it's working for me. |

A better question might be "What could a PI do for a knc miner"? What would be the reason? A better question might be "What could a PI do for a knc miner"?
What would be the reason?
I don't know, maybe it's: - a proven linux platform ideal for the application - well supported in the community (see Minepeon) - well supported technically outside the community, with thousands of applications and many developers - cheap I don't know, maybe it's: - a proven linux platform ideal for the application .................. which requires re-flashing & programming a PI, and separate power & data connections. - well supported in the community (see Minepeon) .................. Exactly... The "Community" has been using it as a workaround to having an actual computer connected to the miners... "Macguyvered." - well supported technically outside the community, with thousands of applications and many developers .................. But not needed, and an extra device to deal with - cheap ................. Yet it is extra cost AND time to set up. Okay, I was giving you the benefit of the doubt - but it's now obvious that you really are clueless. I'm done with this "conversation" |

hahaha, no....no Rpi... it has its own linux onboard, with GUI & ssl ...a pi would be useless..
but is does seem, the chips are in, and assembly & test has begun!!...!!..!!
I'm not sure how/why you believe a Pi would be useless.. I'm also not sure that chips are in, did they indicate otherwise? What could the pi do that an onboard linux couldn't? That's why useless.... The new.pics have the heatsinks mounted, which means the chips are under them. a 1/4 mounted alterra fpga would most likely damage the board if you tried to mount those heatsinks to them, so I'm saying, the real chips must be in, and in those pics. Maybe the "onboard linux" is an RPi? Also, the heatsinks could easily be mounted without the chips in place for product photography purposes. You're jumping to conclusions - although I'd be very happy if you're right.  |

Go with the Hakko. Get a decent magnifier too, you'll need it. |

Thanks guys for the advice.
As stated in the U.S. thread, I am going to try to reflow these chips first, and see if that gets me over the hump.
Anyone know the flow temperature of the solder used on the H-Boards? (Probably a question for the "free money" thread).
My advice is against reflowing  if it passes visual tests  It's pretty tough to do a visual test on a colder solder joint at this pitch, even with a scope it's difficult. Easier just to reflow. |

If the 6th chip is working, I think he needs to jumper the next set of jumpers to bypass chips #7 (U46), wouldn't he? SJ 55, 19, 20, and 21...
Maybe, both chips should be looked at i.e. the 6th chip might not be passing along CLK/SPI signals. I pointed out the jumpers so that he what he was looking for. It's been my experience with these boards that bad chips aren't common, but cold solder joints are all over the place. Reflowing these chips would be my first action. |

I posted this in the European thread, but I thought I would try here as well. ------ To get my 25 GH, I received a card that is functioning at full capacity (~19GH) and an "EOL" end of line card with is running about 6 to 10 GH. After looking at the stats.log, it appears that the EOL card is only seeing the first 6 chips. I took some macro hi-res pictures of the chips 6 and 7 (45 and 46 labelled on the card), where the spi communication I am guessing is broken. https://i.imgur.com/Iddp2WQ.jpghttps://i.imgur.com/MpXXHdS.jpgFor the life of me, I don't see anything out of the ordinary. The european thread seems more advanced at getting full speed out of these boards and was wondering if any experienced eyes see something suspicious. ------- Anyone know any useful threads/posts on the pinout of the bitfury chips or which traces should be cut/shunted to bypass a broken chip... probably chip 6 as that is the last detected chip. See my response in the other thread. As far as traces and jumpers go, look at SJ16,17,18,54 |

What does cutting the trace do, simply cause it to skip it and recognise all the chips after it (7-16)?
Physically breaks the connection between the chip and the CLK/SPI bus. Even if the chip isn't hashing it could cause issues with the function of either. |

Hey Guys,
I am an american who bought a starter kit from megabigpower. To get my 25 GH, I received a card that is functioning at full capacity (~19GH) and an "EOL" end of line card with is running about 6 to 10 GH. After looking at the stats.log, it appears that the EOL card is only seeing the first 6 chips.
I took some macro hi-res pictures of the chips 6 and 7 (45 and 46 labelled on the card), where the spi communication I am guessing is broken.
For the life of me, I don't see anything out of the ordinary.
The european thread seems more advanced at getting full speed out of these boards and was wondering if any experienced eyes see something suspicious.
A few things to try: - reflow solder joints, especially on SPI/CLK pins of chip 6 and 7 - failing that, short jumpers to bypass chip - if it still doesn't work you may need to also either remove the chip, or if you don't have the tools to do this you could cut the traces |

I've received my tracking number for order #4x Thanks Dave and great work! |
|
|
|
A response to an email I sent to Dave: XXXXXX please bear with us here, we are doing the best we can. You'll get a tracking number as soon as it ships.
Sent from my Windows Phone If sounds like they have their hands full at the moment. |

Ready to ship today... No status changes over the weekend.
Weird.. I even sprung for the expedited shipping. Hopefully it's just that they haven't gotten around to updating my order status (yeah right) |
|
|
|
Mine has shipped... Flat rate delivery. Tracking shows movement from muame, Ohio.
Did yours only go to "ready for shipping" today though, or was it shipped on Saturday? |
|
|
|
It doesn't sound like the extra h-boards were needed for the August starter kits as Dave had a fair number of 25GH performing boards. Maybe I was misreading his update.
That was my impression as well. By the way: has anyone's order status changed to "Shipped" yet? |

snip of back-and-forth
Update
I've added option for UPS Express Saver shipping, and dropped the prices a bit as further october orders will most likely ship in very late october. Those who picked first october orders are likely to receive theirs in very early october, if not september.
Regarding invoices: there was a problem on the site. I will need to send invoices manually. You will get an invoice, don't worry.
I need to sleep now. Shanghai awaits tomorrow. I should have more news for you in about 30 hours.
Punin said a few weeks ago that he expects to start shipping in early October if not late September.. I would expect Dave to be working with the same timeframe, but who knows. |

Still nothing from steamboat? He was online about an hour ago.
When the deadline passes, I think it's pitchfork time.
I'm curious as to what deadline you're referring to? |

My order #4X just went to "Ready to Ship" |
