my changes, only:

810mv and 600mhz .... 11 000gh / s for 1100W on the wall 220v

Odd wonder why you see more of a decrease.  Can you share the code or snippet or at least example line where it's changed? thx

OK that's cool but I have mine set to 780 & I'm not seeing as dramatic of change as you.. Maybe you're changing in different spot in the code?

Hi, in fact I change the original tenssion of 870mv to 810mv which is largely sufisant (have can go down edge and keep the stability), with setting pushed and some small mode I managed pushed the efficiency at 0.095j / T (original 0.133j / T) without asicboost ... the official firmware asicboost bitmain is a disaster ... and I also change the management of the fan, in the same spirit as you;) finished them fan has the balloon for nothing! but for the general public I kept a very wide beach ...

Persso, my T9 + is coded with fan between 20 and 40% and a trigger temperature range at the top speed from 95 ° and full speed (40%) at 105 ° ... but this is only my setting for my environment only;)

PS : if you copy me your kernel newspaper I might be able to tell you where your lack is ... and what to modify to improve this;)

No sorry, just changed card voltage...

Wow 300 watts reduction?!? Shocked  How low did you set the voltage?  I set mine to 780 as a test and while the temps run lower & fans are little slower/quieter I'm only seeing very minimal power savings at the wall for some reason..  As in at fixed 450 mhz frequency, 4 watts per card so ~16 watts less reading on my kill-a-watt:

Code:
Chain[J4] set working voltage=780 [54] orignal voltage=930 [0]

(The typo is theirs in the code.. lol)

I got the fans tweaked exactly how i like them now!  Instead of the annoying way too fast or the ramping up & down over & over, I can basically now set a goal temperature & the fans auto-tune accordingly.  To me this makes a lot more sense than the nonsense they build into the antminers. Wow that code of theirs on github is a mess.

But yeah it'd be cool to know what you changed. Smiley

Thx
Bill

hey precisely I try to take control of the fan but I can not ... waiting to change the temperature range in the control fan

is this the asicboost/version rolling version of bmminer?

Hi everyone, I decided to share my Bmminer edit for T9+ (and tested), here are the mods:

- Reduction of the consumption of 300W approximately !!!
- Delete Pic Flash ERROR (now working)
- Custom Fan Management, run with VERY LOWEST NOISE !!!

The usual procedure:
Rename the Bmminer Bmminer-Old in / USR / BIN to be able to restore it if needed .... Then replace it with mine, do not forget to give it the right to execution "RWXR-XR-X"
