OK yesterday(today) I was up till 4:00am... One board do work the rest don't... No idea why... MrTeal also didn't give me the answer...
Today we redid x-ray of the boards and compeer it visually... It is the same... We also made some boards with the ather board just to be sure that the board is not to blame... They act the same way...
Board that is working has only about 60% of engines working. So it runs at about 23-24GH(not sure if that is related). Others have almost all working and they run for some time then they crash... It looks like it always happens at same chips voltage... Some crash complicity others start producing HW errors and chip voltage go to 0V...
Will need MrTeal to figure out... It would make sense if none would be working but this is not the case... All were made from same batch of components the same way and only difference we can find is number of working engines on chips...
Lucko, Chips are from the same batch as Coindo 16 chips board? |

Lucko,
Chips are from the same batch as Coindo 16 chips board?
No... It was one of the ideas I had... I will probably send one board to MrTeal as soon as he say he is OK with that. The other is now going on oscilloscope to look for a problem... But personally I think it is ether problem with one of the components or firmware... EDIT: By component I was thinking batch of components made with error... |

Can be a heat related problem - probably on DC-DC converter ? If all temperatures are OK I would check next decoupling capacitors and DC converter filtering capacitors: with so high currents flowing capacitor impedance is important to overall stability and usually is not primary concern buying components |

At the end of the video when it crashes and stops hashing what is the message it repeats over and over? Also I hope that loud crack wasn't coming from the chili.

With only a single LED flashing, it looks like maybe the MCU has rebooted. The LEDs are numbered 1 (closest to USB connector) to 8 (closest to the PCI-E power connector). Is it LED 7 that is blinking? |

Is it LED 7 that is blinking? Yes this board reboots(7 blinking)... But some just drops 1 V rail to 0 V and start producing HW errors and hashing blinking speeds up... But this board is now hashing at 41GH... But if I turn it off it will probably stop working again... I need to restart it enough times and it works again... But if it reboots it reboots at 0.97V and 27GH... After about 200 shares... |

Rest looks ok for non good vrm cooled boards at ambient temperature of 30 °C. Some of them has not a backplate which I will mount on weekend. Maybe than they will hashing faster. What I'm missing is a way to understand the which temps are shown in bfgminer the detailed view of each board as like it does for BFL miners in bfgminer (processor like stats) check the internal temperatures of each chip shows the frequencies of each chip ... Whishes over whishes... Cheers... |

The problem is that is not stable... Every Chili has voltage/hashing speed(they do go up in parallel) that is critical. And if it goes over it it will work but if not will crash... Using more then one is impossible since it crashes mining program...
I really can't find anything wrong with them... Today test showed noting strange. Nothing is to hot no spikes... I do need to make some tests with Digital Power Designer software(need to figure out how to use it) that control chip power supply... That will be done tomorrow...
And it is different problem with different firmware on Chili. If I use old one it start producing HW errors if I use new one it restarts...
One card that is working is probably below problematic hashing speed...

Hm, how much pcbs you now have allready tested? Maybe they are only spikes in the whole order and so are really lemons  ? How much hashing engines are activated after some hashing? Do you tried to use bfgminer instead of cgminer? I've here a new Thermaltake 730W PSU which looks like give also "not so ideal" hashing results with my both boards which have hashing problems. They have also problems with my new Enermax Revo PSU, but have little bit less hw errors so they hash ~ 1 GH/s better than with the Thermaltake. Connected to my good boards I cannot see a difference. But if I read some posts in Mr. Teals forum it looks like that some have problem where most other didn't have. If hashing with 30 GH/s is possible without special cooling of the vrm the board should be ok. So my last question is, how much boards never hashes or hashes really pool, arrive <25 GH/s, > 25 GH/s, >30 GH/s, >35 GH/s? Also how boards are affected and when will the boards which are not affected send to us? |

1 board 23GH no problems... Only 70 engines.
The rest of the boards are over 118 engines...
5 boards looks to be 30+ but can't get them to hash for longer then minute to get to speed...
2 boards 36 and 38(with additional cooling 41 and 39) but they don't run every time for cold start... But if I stop mining software and restart is fast enough(so that the voltage is still over 1V) board will start every time...
In most cases if problems starts at 24 to 29GH. Only one board crashes at 38GH.
Now I can't figure it out why boards run for some time then restarts. I would say that it is put together right but no idea why it then restart and they restart even USB so they get disconnected from computer.

BFL did have problems with engine 0 making the miner unstable,
Can you disable engine 0 within the software? and then test without engine 0 running on each chip?
