That's what I figured, thanks anyways.
There is no actual fault in the miner, but the hash board in chain #2 doesn't have as good quality ASIC chips as the two other boards have.
Thus it is not able to perform as good as the two other boards do.
The variety in the chip quality is an issue in the 16nm chip production and that is why Bitmain has produced so many different hash rate models.
As fanatic26 mentioned, that HW error value is not an issue.
Makes sense.
The miner is good, my heater broke down, so it's not only making me money, it's keeping me warm right now too lol
