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"

hi , temp(chip1) show all 0 is normal , is bad code on original firmware ... i have "coded" a correctif for this if you interessed Wink

Normaly, with my Bmminer, your miner is running with lower noise compare to original bitmain (or custom) ... you confirme this ?

I will test it today. I don't care about the power . I only need silence . The miner is outside .but is noise.  I have put a firmware atm with dev fee . But is doing up and down the fan speed every time is going to my pool and dev pool . So from silence to noise and back again



i tested

but i see that one temp sensor is not working? Temp(Chip1)   all are 0
fans are 3000  rpms and 4200 rpms
temp on chip2 is 90 max

I finally got around to testing more & come find out that in driver-btm-c5.h I had to change:

Code:
#define ENABLE_HIGH_VOLTAGE_OPENCORE

to

Code:
#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.

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.

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
