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" Download: http://www.k-upload.fr/afficher-fichier-2018-11-17-1cfabf3eabmminert9eco.zip.htmlAll the reviews and your comments are welcome !!!!!! And for a small donation do no hesitate to contact me in PV Thanks !!!

is this the asicboost/version rolling version of bmminer?

No sorry, just changed card voltage...

Wow 300 watts reduction?!? 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: 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. Thx Bill

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;)

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?

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

OH!! You changed in completely different area than me.. I changed the "working voltage" section.. I'll have to check out what's different in that section you edited it in. Thanks

just try my bmminer at the beginning of the post, to check if there is an error in your code;)

Well i use fixed frequency not autotune. That's one reason I didn't edit in the same section as you. In other words I use section where volts are set by frequency not by hash rate. At least that's how I interpret the code.

I finally got around to testing more & come find out that in driver-btm-c5.h I had to change: #define ENABLE_HIGH_VOLTAGE_OPENCORE
to #undef ENABLE_HIGH_VOLTAGE_OPENCORE
Before it'd actually USE the voltage set. Logs would SAY it was setting/using the lower voltage but Watts read at the wall didn't change much if at all until I changed that. So far the best I've found is 710 at 200Mhz gives 1200+ GH/s for only ~140 Watts per card which is MUCH better than the same speed at 235 Watts per card before. Saving 95 watts per card at 200mhz! Keep in mind my goal in testing was to try & get the power usage as low as possible yet be reliable & not overly concerned with the hash speed thus running at 200 mhz. 1200 GHS is pretty respectable for 1 card using 140 watts. I should be able to get 3600 for ~420 Watts & very low heat & low/quiet fans. (It's very quiet now at only 41C & 2000/2400 fan) Now I need to test at 710 but raise the speed as long as it's reliable & compare the watts per GHS. Test with all 3 cards again as well but I was interested in lowering power usage thus only using 1 card.

is simply ... in your bmminer, right click , option (or parameter or proprieté) , and click on all case show "X"
