Re: 10 chips avalon module board fired up, help! <3 picture uploaded>
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?
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.

I agree you can better fix this yourself, just replace it and see if it burns out, if it does something is drawing to much power.
"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.
Re: 10 chips avalon module board fired up, Ngzhang HELP!!!!!!
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.

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.

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.

I just send 9.98741119 to address: 1DVb2K344enseUQ3bNKm8q95iHfaT2Yj4T

Try http://blockexplorer.com/
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.
send BTC from BTCGuild.com, but I can't see any transaction info

BTCChina.com provide this address to fund BTC.

Avalon ASIC powerful noise fan replacement, can it feasible?
Use four series connected 12CM 76CFM quiet fan to replace one noise Delta FAN.
Can it applicable?
The low noise fan specification:
Air Flow: 76CFM
Speed: 1600RPM
Bearing Type: Hydraumatic
Dimensions: 120*120*25

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?Both of my order have all received.
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.
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.
