Hello,
i had same issue. And i solved my problem. Problem is in one or more chips.
Install, for expamle HiveonOS and set chain frequency on 55Mhz (in Asic management) and hashboard start hashing, (maybe)

Then check Asic Management and send us screen shot.
This is my screen shot of my hash board, i changed Asic chip number 50 and board start hashing.
