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.

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

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

Hi Taserz, i have one S9 and i try your BMMINER 890 and working very well ! good job ! 
but i have one problem, the option "fix-fan" ase removed ? how to activate to fix fan at % ?
thanks

It still will run properly it just doesn't show it for some s9 models but not all.

Hope to get yes/no answer.
Yes it's all done in C.

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.

Please share, would love to try some

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

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?

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?

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++.

What temperature in kernel log should be watching?

if I can allow myself,
Original T9 + = 10.5Ths ==> 1450W at wall 220v
My T9 + = 12.5Ths ==> 1400W at wall 220V
Its worth it 2Th free! ?
Regards: p
But I agree 100% not to mount Bmminer S9 that VERY strongly risk giving the error "PIC Error" and brick one or more hash board ...

That's impressive, can you give more details, volts you used, clocks you used?
Anyone did the same with S9?

well, sometimes you are lucky and able to rent a darn cheap place andhave E included... 
It will be HOT HOT HOT (sing it)
