leiyplane, you seem to have 2 if not 3 decoupling capacitors at the 12V input that burned out. Maybe faulty caps. Can I offer to buy your board for 2 BTC? Or I can offer to fix it for free if you want it back... I can cover shipping costs. I would be interested to study the board in my hands out of pure curiosity. Email me at m.bevand at gmail.com
Also, the people recommending you a higher wattage PSU are wrong. A 3-module non-overclocked Avalon draws only 500W @ DC (12V + 5V + 3.3V). A 650W PSU is plenty enough (~77% load).

I suppose that you could fix this by yourself, it is very easy to get such components at electronic shops. Or you sell the chips and make BTC right away  He ought to sell it to a developer. I am sure they would love to take an early look at one of the modules to get a headstart on the open equipment version. P.S. Whatever you do, don't sell it to anyone at BFL. They will reverse engineer the Advanced ASIC technology from the Chinese people.   We can pool some money together and send it to BKKCoins... he is the one on the cutting edge of an open source Avalon DIY PCB... can we make an offer? Damn, the Avalon components are worth something even when they break down. Might as well be solid gold. Well the chips are... I would rather he gets it fixed and keeps hashing... but damn it be nice to get some of these chips in designers hands today. The DIY avalon will be the way we the people can keep pace with larger entities who are building larger and larger farms. I hope you can take your module in and get it fix OP... I am sure you can find someone to do that but if you can't let us help you scavenge it for the DIY Avlaon community out there. I'm not plan to fix it, I think the PCB is broken up. I hope my experience can help other people, if someone(Avalon Customer) have the same experiences with burned module board, and let Avalon BOX resume operation faster. |

Thanks for your advice. |

"the power supply is antec 650W, there's no problem with PSU."
You need a higher wattage supply. When you run one that close to the limit, you highly increase the amount noise on the power rails. The component failure on this board is probably related to that.
Thanks all of you for advice. |

Is the fired module located near the exhaust or the intake?
intake, near the fan, is a No.2 module in the middle slot. |

Very sorry to hear that  If you post a close-up pic, it would help debug the issue, or throw more light on it. I think faulty SMT electronic element cause the problem. |

You should post some pictures.

What was the ambient temperature when it "fried" 3 sub modules?
the ambient temperature is 25 centigrade. This burned module cause entire avalon box stop running. I tear this burned module off, avalon box running again, but the total speed is about 2.7GHash/Sec less. |

10 chips avalon module board fired up. One of my avalon chip module board fired up, I tear this burned one off. Now only 7 module board running in a slot. Where can I buy a new 10 chip module board?  ?? No modification, No overclock history, the entire avalon running in stock clock.
the power supply is antec 650W, there's no problem with PSU.photo by Nokia E72 close up.  photo by Nokia E72 close up. This 10 chip module cause entire Avalon Box stop running.
Note: just this module burned, other module in the slot remains intact.
I tear the burned module board off, Avalon can run again, but with about 2.7GHash/Sec speed loss.The speed reduce to 64GHash/Sec, about >2GHash speed losed. Thanks for Avalon moduler design, The Avalon Box Survived.  |

blockexplorer.com has no transaction info too.. I experienced the same problem a few times. U have 2 options: - relaunch client with -rescan (voodoo magic, sometimes works) - wait for 24 hours, the transaction should appear in the blockchain or funds will come back. Thank you for the suggestion. |

how many transactions does your client say ?
which client
BTCChina.com provide this address to fund BTC. I have no client, I just send from BTCGuild to BTCChina.com |

I have received my second Avalon, I will light it on tonight.
Both of my order have all received.
Mind giving your country of origin for the list? China. |

Dalkore, put me down for two received today, United States. Third one will be here on Friday, but I'll reconfirm at that time.
Congratulations. |

congrats. When order were shipped according tracking info or documents? Thank you. There's no tracking info before I received Avalon. SF-express call me yestoday, tell me there have a big package to deliver tomorrow. SF-express waybill must have number above barcode. Usually this number is tracking number... (at least at EMS, DHL and others companies...) Yes, I just get the tracking number when I received the package. But right now, waybill numbers are not here, so now I can't tell you when order were shipped. SF-express usually deliver shipment within 1-2 days in China, 3 days at most, a lighting fast express company. |
