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 Grin

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. Cheesy

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.

How about my 2 BTC offer? Not high enough?

So how about 4 BTC to buy the broken board?

Good to know. I'll make sure to oversize the psu when I build mine.

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.

Well, its good to know that if a row of ASIC chips goes down due to something like this happening, it doesnt take the whole unit with it =) .. thats pretty nice imo.

Is the fired module located near the exhaust or the intake?

intake, near the fan, is a No.2 module in the middle slot.

Ok, bad coponents then. I thought that was caused by the uneven cooling, but that will fire the components close to exhaust first
