anyone else have input on this? lol I have no idea if this is ok or if it's actually a problem with the board.
I have one S9 like this too. After 38 days since last reboot 1st card HW 51575 - 2nd card 4724 - 3rd card 463 total 56763 - 0.0005%
Shortly after I put this unit online I sent the HW numbers to bitmain support asking if there was an issue with the card. They responded that it was normal and not to be concerned. The miner is working good with no issues.
Bitmain support response below
"Thank you for contacting us. Some hardware errors are normal and expected in a good working miner. The errors on your miner are ok. The miner appears to be working well."
