What should I do if the HW error is high in the hashboard status shown below the hashrate chart?

The HW error displayed in the Hashboard status is only for a short period of time, and the data from such a short period is not sufficient to determine the root cause of the issue. To accurately assess whether the HW error is too high, you should check whether the average hash rate displayed above the hashrate chart is within the normal range. If it is within the normal range, then the miner is functioning properly. If it is below the standard value, further examine whether the HW error exceeds 5%. If it does exceed 5%, then it is considered to have a high error rate.
