Title: S9 one chip has lower hashrate, 100 HW/hour while others have 0-2 Post by: iluvbitcoins on February 15, 2018, 02:21:41 PM It's not much of a loss, it's 13.3TH/s
But still, why does one chipset constantly mine with a lower hashrate? This is what I get in an hour http://prntscr.com/if6htv Version http://prntscr.com/if6b6l This is the first ASIC I'm actually hosting by myself, so don't be harsh if it's something simple :D Title: Re: S9 one chip has lower hashrate, 100 HW/hour while others have 0-2 Post by: fanatic26 on February 15, 2018, 04:32:17 PM The hardware errors you are showing are pretty meaningless. Normally you need to see tens of thousands an hour to be worried. I would just try a different firmware, it looks like your autotune is not doing its job properly.

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.

That is why I recommended a firmware change.
Title: Re: S9 one chip has lower hashrate, 100 HW/hour while others have 0-2 Post by: HagssFIN on February 15, 2018, 10:42:03 PM That's because it is not a autotune firmware.
That miner is a non-autotune version and the firmware is the latest available non-autotune firmware version.
