Ummmm.. I have no idea what is your point in all this

Mine in a proper good pool, that's the lesson here

You have made some major fuckup while cleaning them.
I hope you only used IPA and compressed air?
Using things like water, soap water or vacuum cleaner will guarantee a bad result

I don't know, I never studied and bought tools for board-level repairs.
Maybe ask companies like Canaan or Zeusbtc about board-level repairs?

Now that I read all through again, it may be that the hash boards are all toasted

Maybe the MM board is broken? Can you try with a surely working MM board?
How does the pmu voltage measurement values look like in the cgminer api log?
Can you post the log here? (please insert it inside code tags, it's the #-button in the message panel.)

That miner is quite rare. You might find more Bitfury B8 experts at Russian speaking forums (eg. Bits.media). Please share if you find something there.  |

You need few million bucks for competetive asic development. It is no more an easy task for small operators like it was in the early days (Avalon1, Antminer S1......).
Builders sidehack (Gekkoscience) and jstefanop (Futurebit) have been using Bitmain and Bitfury asic chips for their btc miners.

For clarity, I don't want to take sides here and I don't care about merits in use such as this.
I just really hate, also in arguments related to my daily job, when people go personal with the arguing. Things too often go off rails to emotional level.

@zoghotaa Does the B8 miner have a total number of two PSUs? After I looked at your logs, it seems to me that there is an error with the PSU in the first slot (slot 0). It looks like the miner is unable to communicate with the PSU. And also it most likely does not give any DC voltage output. This could be verified with a multimeter. Do you have a new PSU you could try? I think it has to be the exact same type as the old one. edit:Based on all the info I've got, this is the power supply model used in the B8 miner: Eltek Flatpack2 48V/3000W HEhttps://www.eltek.com/us/products/flatpack2-483000-he/I know now how to operate a Huawei psu in b8 login with putty and write the command echo -n ' -no_psu '> panel/home/data/conf/- no_psu now b8 hashing That's great! I gave some merit. Can you also share the exact details about the Huawei power supply model you are using? It would be big help for other B8 users in the future. or any psu 53v Thanks! So one alternative power supply model for Bitfury B8 miner is Huawei R4850G2 power supply. I saved the datasheet here for long time archiving: https://mega.nz/file/E9lAkBoY#8qYt1nsjHtJ3ajAXMzkkfmUtiWPYkm0W1fy9fqMqO8w Using this psu model requires the small mod which zoghotaa described earlier. |

No.
You need a APW9 power supply.

Kano you don't have to go personal, be the bigger person...
Merry xmas everyone and please set the pool arguments aside for a while, and enjoy your time with family etc.
