I have this in my "bmminer.conf" "bitmain-fan-ctrl": true,
"bitmain-fan-pwm": "55"
It works perfectly well ... but once your custom Bmminer use, the fans are in auto ... |

I believe his bmminer ignores config file fans. Mostly because someone would turn them off I'd assume lol

Does anybody know a firmware that tunes the chips individually without devfee? I would like to try to find out if that decreases HW errors...

It's per chain ignore that garbage you see floating around it has a dev fee and does nothing it advertises. |

There is not information on the first page about dev-fee for this firmware. Is there, percentage? |

This firmware has no dev-fee. Many of the others have dev-fee or hidden dev-fee not mentioned. This is for free. If you want to donate coin you can. A few users have done so and I am grateful as I tuned some setting to what I think is ideal. |

Works with the newest low power patch from bitmain. Dont know what is modified by the patch though. 50-100w less power consumption 0,2-0,4 TH less.

What voltage and clock did you use? Since actually, I have a different conclusion... With this setup: 13.5TH/s unit 910v 825Hz ~1950W at wall ~17.4TH/s achieved with previous fixed firmware. And with newer firmware everything was the same except the hashrate. It achieved 17.6-17.7TH/s. Will have to let it work for 24h to get exact results. Tho, I am using 1600W Bitmain's PSU. |

Voltage 880 and 787MHz.
The hashrate changes sometimes depending on temperature even if you just reboot without changing anything.

Yeah, I noticed the spikes and dips as well. We will see how it affects the 24h average. |

Everyone is my thread is overclocking but I do have some bmminers with lower voltage for undervoltoing
Hey @taserz, can you maybe check if the recent Low Power upgrade by Bitmain affects your config? It seems a bit suspicious how the miners hash after applying the update. I also saw in the archive of the update, that there is a bmminer file. maybe it overwrites your bmminer?! |

On a stock S9 I can confirm that the LPM firmware either modifies or replaces the bmminer file, I would assume it would replace a modified bmminer as well. The LPM bitmain bmminer does not work with slushpool.
I added Taserz bmminer after the update to LPM and it does work with slushpool. This modified bmminer seems to run faster with LPM checked, maybe someone else can confirm this, I don't have time to check on multiple machines at this time. bmminer880 650 freq 13.950 th/s. With LPM unchecked I see readings closer to 13.825 th/s. I don't have access to power readings at the moment unfortunately.
