Even in the event that an attacker gains more than 50% of the network's
computational power, only transactions sent by the attacker could be
reversed or double-spent. The network would not be destroyed.

Hey guys. Further findings:
Right now I am trying to find the sweet spots for the miners. I tuned the S9s individually and I am using bmminer 880 and 890, depending on chip quality. The 14.0 TH models run at 787,5 - 800 Mhz and draw between 1800 and 1830W. I managed to draw up to 1930W from an AWP3++ PSU, but thats too near at the safety shutdown point. The range for safety shutdown seems to be between 1870 and 1950W at least for my AWP3++.
Question: Would you prefer nealry 0 HW errors and lose about 0.2 TH or go with the HW errors? I try keeping the HW errors very low because I assume it affects the hashrate more than the extra 0.1-0.2 TH. What do you say?
amazing, my APW3 cut a 1680W wall 230V ... can be other serie? |

Its a AWP3++ I measure at wall with TP Link smart plugs. HS110. What about this question: Question: Would you prefer nealry 0 HW errors and lose about 0.2 TH or go with the HW errors? I try keeping the HW errors very low because I assume it affects the hashrate more than the extra 0.1-0.2 TH. What do you say?

hi all, i've got recently used S9 13.5T from 2017 oct or nov batch, when i uploaded and set bmminer880 or bmminer890/bmminer9v it shows no information about chip temp. i also noticed that with bmminer880 or bmminer890 it shows 12.5 TH, but with bmminer9v shows 14.3 Th, but still i dont see chip temp = anybody faces the same issues?

How lucky have you guys been with undervoltage?
How low can you get, how efficient can you be while keeping the default frequency?
Everyone is my thread is overclocking but I do have some bmminers with lower voltage for undervoltoing |

Please, tell me, can I rewrite firmware for S9 from PC or I need flash-card?

Look below in the sub section your in for compiling bmminer from bitmain git. NVM, just got the link for ya. https://bitcointalk.org/index.php?topic=4030824.0 |

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.
