how i can different voltage in hashboards

[moritezza]

Hello

how i can fix below log on t17e:
i used hashboard from different devices, and seems one is different voltage, how i can fix it?

Code:

What exactly your problem why you want to fix the voltage? If it's running fine with the correct hash rate you don't need to change something in your miner.

Can you post the whole kernel logs use this https://pastebin.com/ then paste it here.

You can't manually tune the voltage of your miner if you are using factory firmware unless if you are using asic.to firmware where you can able to change the voltage and overclock the hash board. But I think it's not supported yet on t17e but supported on both s17 and t17.

same hashboard is different voltage, with hiveos and other custom firmware show me soc error and cant load. and with firmware bitmain it run fine but after some time it show ideal hashrate 0 and miner stop working. and exactly same hashboard is more hot (90 degree).

i should with code editor copy good hashboard and paste to bad hashboard right? cause i used this hashboard from other miner.

there is no other way without code editor i fix and mix this hashboarda?

Thanks.

With any miner that is using a single built-in PSU such as the T17's all hash boards are fed the same voltage. Unlike the s9 and lower the hash boards in a T17xx on up do not have a secondary Vcore regulator so you cannot change the voltage per-board - eliminating the 2nd stage regulator that is at best 94% efficient and more likely around 85-90% is part of why new miners are more efficient.

so what is this? its fake?

Sometimes when we use the hash board from different miners in one, or after using the test fixture to test, the miner probably can't start working, it's because the code in the hash board is not unified, we need special equipment to refresh the code, the machine can restart work.

Note: This problem doesn't hardware damage, but because the Hash board code is not uniform, This special code has been written into the hash board at the factory, and this problem probably occurs when repairing S9SE  S9k  S11  S15  T15  S17  S17+  S17pro  S17e  S17plus  T17  T17e  S19   S19pro  and other subsequent models.

It is not fake.
However, in the pictures they are dealing with what looks to be a s9 or other hash board that uses secondary on-board regulators that set the voltage applied to the chips (Vcore) on each board. If a board has PCIe power plugs then the board has the 2nd stage Vcore regulators and yes you can program voltage per-board.

When a board has hard metal bus connections fed from the built-in PSU and all boards are bolted to that bus - forget it. Yes Vcore can be adjusted by the controller commanding the PSU to put out whatever works best BUT that voltage (found by tuning) is a compromise derived from results of the combined boards. Perhaps one board *can* use lower voltage, perhaps another needs higher to be reliable but all are fed the same voltage so the result is xx Vcore is at best overall compromise.

No, it's legit, NotFuzzyWarm answered based on your question which is wrong, to begin with, your problem has nothing to do with the voltage, it's just hex code that is stored somewhere in the hash board, starting from the S9k series onwards, you can't just mix hash boards from different miners, every model will have like 2-4 different codes, usually labeled as 0,1,2,3, the kernel log will display that at the beginning, which is why you should paste the FULL kernel log so that we can help you further.

With that being said, since there is always a 25/33% chance that the mix will work, you don't simply assume your problem is just mixing the boards, there are many other things that can cause the problem you describe, so please post the kernel log and a screenshot of the miner status.
