Well, this applies not only to your miner, it generally refers to the method of detecting errors in data transmission over the network through the use of checksums. In general, a CRC error indicates that the data transmitted over the network does not match the expected value, indicating that an error occurred during transmission. This may be due to a number of factors, ranging from noise during data transmission, deterioration of signal quality and ending with data corruption during transmission.
Upd: As for your case, it is most likely a communication error that occurs between the ASIC miner and the control board.
Yes absolutely, did you tried to change the data ribbon cables ?
