Asic.to Custom Firmware - Optimize Performance & Efficiency S19/S21/T21

[taserz]

Really? Who pays for that? You could also just write a batchfile with the commands. Its like 4 lines of code  

Ehh you got to ssh into it stop the file ftp connect to it upload a file blah blah more than just a batchfile i don't think you can ftp over cmd

After flashing with the LM my temps dropped 3c each board on average and fan speeds around 3-400. 5 days later and my hashrate has decayed from around 13.5-13.8 to around 12.1-12.5 (S9 13.5). Don't know about Watts pulled as I'm not on site. Will reboot and see if that boosts the hashrate back again.

This seems to be a common problem with bitmains new firmware

[Mousem40]

Yup, back up to 13.5 after the soft reboot. What a PITA.

HI
Can you add Asic Boost?

Lemme translaate:

Hey taserz, can you tell us, if you are working on also modding the recent firmware by Bitmain with Asic Boost? What do you think, when will you be done?

Actually, I am also courious. I am thinking of rolling back to the old version. But if you say, you are done in some days, I will wait and start with the new version and fine tune it.

Yes but it seems that it might not be worth it. I am seeing many report that the official LPM that Bitmain has on the new firmware for AsicBoost saves a little bit of power but the hashrate slows down overtime resulting in a negative impact on mining performance. I don't think I will have a working version for a little while I have my machines hosted elsewhere so whatever work I get done is from others letting me try code on theirs and it's a slow processes and a shaky one since I don't want to brick a hashboard and have to have someone reload firmware.

[Andartis]

Latest firmware should fix hashratedrops, like Bitmain says.

[selfblumpkin]

Latest firmware should fix hashratedrops, like Bitmain says.

It certainly does (thank fucking god)

No decrease in hash rate, running for ~4-5 hours.

With other ASICBoost firmware i was seeing hash rate drops by this time already.

[sohail289]

new LPM firmware has stable hashrate. waiting for taserz so he can compile bmminer with different volts i dont wanna stuck with 870mv 675mhz

Is anybody here to share experience of this firmware with immercion cooling?

It works fine no fan check.

Hi taserz,

This is properly awesome, so thanks for putting this out there. It's also gone some way to helping me understand the chip temp readings on my S9i.
I've been playing with the Braiins OS firmware for AsicBoost support and getting really high temp readings, the same happens with your 880 bmminer. I looked through the logs I noticed a few differences:

Looks like it might be a special version of some sort that makes up for a lack of sensor? Is there anyway around this?

[dutchlincoln]

Taz, are there already mods based on the 2Nov fw?

[Andartis]

Because it felt a bit messy after patching 3 times over the modded FW, I resetted my S9 and reflashed them (and resetted again) with stock autotune + recent LPM to check on LPM. Actually, I dont see any difference, although I mine on Nicehash asicboost and its also activated in firmware. You would expect like 10-20% power saving, right? So like instead of 1300-1400w, you would like to see like 1200w. Thats not the case. Or did anybody else have other results?

[sergw]

Any chance to get this bmminer with LPM support as i see braiins os already done that?

[favebook]

Taserz, do you plan on making a firmware for upcoming S15 and T15 which will soon be released or is it too early to ask such question?

[thierry4wd]

In my opinion it's too early! the source code will not be released from as early as I pence ...

Nevertheless, "the code" between antminer S7 / S9 / T9 / T9 + are the same, finally in large part, there will be way of tunning a little anyway I pence!

I would like so much to have one: P !!!

[taserz]

I think the reason my firmware and braiins is heating up a bit more is because many of the newer releases from bitmain have not been made public so figuring out what they did to lower temps is difficult since the source code we have to work with is a few revisions old. I am trying to figure out the LPM but it is currently not being very friendly with me.

With the new S15 I might just try to work on that one if I can get my hands on 1 even though the tax is stupid high.

[taserz]

Hey taser just a quick question really have you tried this on a l3+? Im curious to see if i can get lower voltage out of that thing. Thanks

There is already a modded l3 someone made. It takes a bit of a dev fee if memory is correct.

[Gmzombie]

Boo i like your updates better. Thanks for the quick response
