hi, so 40 chips are being detected from 48, sometimes its only 37.

so only 2 hashboards are working. is there any way i can make first one work only on 40 chips?
thanks in advance.

No, you can't configure with software the amount of ASIC chips that are in use.

there are some people that may work on it for you.  you likely need to reflow some chips.

The chips are in series, all of them need to be working, you seem to be having an issue with chip number 41, given the fact that this is a 17 model,  chances are the chip lost contact with the board, you will need some tools and skills to fix that, or send it somewhere for repair.
