S17+ Hashboard #2 find only 64 ASIC / MSKMiner

[antonelli182]

Hi guys

Newbie here, just got a used S17+ 73Th running with MSKminer FW, and I am having some issues with it.
It keeps restarting all the time and looks like the hashboard #2 has only 64 ASIC found

Appreciate any support here
Thanks!

Can you revert it back to the original firmware?

I would suggest you flash the miner with SD card firmware you can download the firmware under this link below

- https://service.bitmain.com/support/download?product=Flashing%20SD%20card%20with%20image

And then follow the guide from this link below

After that test it again and let see if there are changes on the kernel logs. Post the new kernel logs here after.

Try to flash the stock firmware as mentioned above, but it will be highly unlikely that it will fix anything, the problem is here

Code:

2021-09-11 06:48:00 driver/driver-btm-api.c:1289:check_asic_number_with_power_on: Chain[1]: find 64 asic, times 4

You will need to unplug Chain 1 which is the middle chain ( if the miner has not been tampered with) but should be easy to identify, that will most likely fix the problem. and then how to fix that bad hash board is a whole different topic on its own.

Thank you both for the help!

I tried with stock FW but didn't work.. the seller will send me a new replacement board for the faulty one, so I hope that will fix it.

Cheers

You are lucky, the seller seems to be honest, most sellers will just tell you "the miner was working great when we shipped it", hopefully, they will send you a working dashboard, although I'd prefer if you got a 1/3 refund instead, but still, a lot better than nothing.

where are you located? the bad hashboard could likely be fixed, and since it's reporting 64 Asics out of 65 it means likely that the 63-64th chip is bad due to bad connectivity, here are two things to try

1- Locate those two chips, you can do see by reading this > https://www.zeusbtc.com/articles/information/182-antminer-s17-manual-download, apply some serious pressure on both for a while and then test the hashboard.

2- Put the hashboard in a plastic bag then seal it, put it in the freezer for 24-48 hours and then test it.

Yes you are lucky to receive a new spare board !!! but unfortunately it will not work!

the 3 cards need to be programmed together ... if this is not the case, the miner will simply stop the hashing (unless you are using a compatible firmware, I offer one)

That's not exactly true for all cases tho, there is always a chance that hash boards from different miners are compatible with one another, I had success in swapping hash boards from different miners without having to use custom firmware or touch the EPROM, also, if the reseller knows his stuff, he would probably program the dashboard before shipping it assuming he keeps a copy of the hex from the miner before sending it.

With that being said, if so happens that the dashboards are not compatible with one another, I think using custom firmware is easier and cheaper than going the other route.
