The good news is the unit works.  The bad news is you've invalidated the warranty by opening the unit  Cheesy

Ok, a little higher @ 46º... not bad! But 2% of HW errors...

The HW errors percentage is higher initially, after few hours it drops below 1%.

I've found jalapenos running generally really cool (38-42 deg C) if this is at all comparable to GPU temps heat shouldn't be an issue for longevity.

That said the higher the environment temp, the more hardware errors you get, the lower they seem to clock themselves.

It would be interesting to see if the 7 GH/s upgraded Jalapeño's still run @ those cool temperatures.

"I just did a complete teardown of my Jalapeño and now I'm worried about its longevity because the finishing of the shell of one of the microchips is not perfect"

quoting your un-quote, because it makes total sense that he would do a tear-down both for himself and for the internet (I appreciated it!), and to see a chip looking like that is a little dumb-founding. you never know if the shell of that chip is now so thin that the internals are affected or exposed, and that sort of issue may not play out until hours or days (or never) later when the thermal expansion (or contraction when powering down) kick in.

Great photos, mate. I hope to receive mine during this Decade... Ordered it last April 30, 2013...  Cry

Pretty sure you will, still 6,5 years left of the Decade.

One more closed photos of the faulty chip to see it better

This doesn't look good for BFL, it actually looks like crap.
OTOH you better ask them, email or something.

Packaging irregularities likely won't affect the chip in any meaningful way. They're surprisingly common, but you can't normally tell too much from the outside if a chip how well it operates.

Prob early crappy chip with several dead engines. That said, it should prob be fine if you keep it cool and don't fuck around with it.

What's really sad about this has nothing to do with the functionality of the chip.  Here's BFL, who knows they aren't making notebooks to sell at Walmart where no one will ever see the motherboard; they're selling to geeks who are going to tear the case off to look at it as soon as they get it unpacked, and post photos of anything irregular on the forum that their customer base reads.  

The same BFL that right now is trying to sell the very chips that look so shoddy in these photos!  What were they thinking?  Answer:  No, they weren't.

Check the back of the jalapeño when it's running, if you have two leds then both chips are running

there are 8 red LEDs and the center 2 are blinking.
