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.

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.

You should post some pictures.

Very sorry to hear that
If you post a close-up pic, it would help debug the issue, or throw more light on it.

Or recommend him to buy a BFL product.

What about writing an email to the company who sold you the device? or call them??

Do people not know here how real life works??

Shit happens, I think you're the first with a fried chip/board.. Try using support.avalon-asic.com for replacement.

Screaming for help doesn't work anymore these days.

* server installs fire alarm in his unit

Was it the power supply section of the board the burnt ?

I think faulty SMT electronic element cause the problem.

shit that sucks, im curious what they will say

[johnyj]

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

[johnyj]

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

[Tyger]

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.

Thank God your Avalon didn't burn all just you lost 2.7 Gh/s.

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.
