i'm thinking no asicboost at the moment ... bitmain is talking about "reduce power comsuption" but at no moment of asicboost ... so in my opinion no asicboost but just an improvement in efficiency ...
I also achieve the same performance just by moding the bmminer codes,
With their bmminer "lpm" the core open at 810mv which is far too little, and which is clearly planted chips ... they must open at least 910mv (original 930mv) ... I tested the downclock and no more problem ... but hashrate very low ...

me to , i'm not use autotune, "autotune" is very badless ....

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

my changes, only:
810mv and 600mhz .... 11 000gh / s for 1100W on the wall 220v

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;)

SUPERS! it is always a real pleasure to see that my hard work is helping! and a gift is the cherry on the cake !!! then a real thank you;)
Ps: Have you tested my eco mode?
|

Strongly that your PicKit arrives, that you see for yourself, I experimented all this, I repeat it there is an error in the source code of bitmain for the T9 + (by the way I share a bmminer eco mode, and it works, I've cracked the code for that, just try it after repairing your card), there's just 99.9% chance I'm right, just wait for your PicKit and follow my tutorial, and .. .. ENJOY !!!

with pleasure ! trust me I knew these minor very well (to repair and modify them) and the problem comes from the, without any doubt;)

Whenever someone brags with something with a  and doesn't show any proof I call bs. Granted I can docker anything. No problem I understand;) I certify that it's true, free to everyone to believe me or not, it's not only track that out to the public with dev fee, because miner is no longer profitable for me, so I try to survive in this world as I can;) there is absolutely nothing nasty, although I share some of my know how like eco mode for the T9 + for example;) but perssonne does not seem interested lol, friendly;) [...]
Hi! actually in the source code there is an error that modifies the "firmware" of the PIC32, this peak precisely manages the tenssion of the chains ... even if you followed the program, this error was inevitable, I was also trapped ! just like dollemizer and the others;) to my knowledge, only one solution (for the moment), I explain everything here: https://bitcointalk.org/index.php?topic=5032987.0 |

I thinks work for just copy Bmminer at miner by SSH .... But just try |
|
|
|

Yes of course, I knew that very well lol I just wanted to know if he proposed something new;)

UP ! Bitmain Release new firmware for S9I / S9J and say :
"Add support for low power mode, reduce power consumption."
Any people try it ?

I have the abitude to repair the S7 ... and 3 card that shows 48 asic does not surprise me !!!
Sufi of a single card down and these are the 3 cards that shows 48 ... even if 2 are intact!
THE first test to do and connect only ONE card and see if it works well, so about 1.6 TH and 45 asic (or 54) ... If ok, test another card ... (always meter out tenssion before unplugging and reconnecting a card) ...

hi, the error come on this : chain[2] PIC jump to app dsPIC33EP16GS202_get_pic_sw_version failed on Chain[2] .... you are already try to flash my HEX files ? Or not, put your own HEX (on MPLAB take "extract") from the good hashboard. Connect one of the 2 hashboards that works from the minor to the PICKIT3. And in MPLAB does extract (same as my tutorial but EXTRACT). once the file is recovered, flash it on the failed hashboard, the J2, normally the middle one on the minor;) I'm confident about the procedure, it should work! Thanks for giving a feedback;) |

With pleasure !!!! A big thank you for this donation !!!! really generous, it's very enjoyable !!!!
please s9 for hex file.
I'm sorry but I finished my development of S9 (AsicBoost + fan + voltage) and so I do not have it at hand ... my work is "for the moment" finished with him ... On the other hand, if you have at least one card that works, you can extract the HEX yourself! if need I can help you;) |

No sorry, just changed card voltage...
|
|

|

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