Then... what about breaking asic-chips? Will 10 chips stop working when one breaks? And does this one has to be replaced in order to let all chips run again?

Thanks!

I could be wrong but I believe he said before that if one chip stops working it will only affect one side of the board (10 chips). So if a chip stops working on an XX board you will still have one side working at least.

Yes, which i believe would not be the case on the Klondike boards. Would it be possible to only have that very one chip stop working only instead (and even indicated, what ships are delivering and not so it can be replaced)? i think that is the question. Which i also would like..

I can't speak for Burnin of course, but I'm sure if it was easy for his design to do this he would've done it that way already.

Also, I found my previous answer is only partly correct sorry. According to Burnin's quote below it depends on the failure mode:

I have a similar question:

Lets say one Chip is damaged - Miner still working ?

The chips, as mentioned before, are calculating in a "row." Which means, that if one chip in a ten chip cascade is dead, the whole row of ten goes down and produces hardware errors.

Depends on the failure mode of the chip.
bang! magic smoke escapes - whole module down, rest of the stack continues to function
chip produces wrong hashes but continues to forward messages - some hw errors in cgminer, hashrate drops by one chip
chip logic completely dead - one row dead from the point of defective chip, hashrate drops by 1 to 10 Chips

My design is spare-no-expense, build for resiliency and reliability.
