Braiins OS & Braiins OS+ custom ASIC firmware: optimize performance & efficiency

[SerbianFarm]

Hey

I do solo mining and 90% of my ASICs are actually running with Braiinos+

Everything is perfect : more Th/s as I wanted

But could you tell how I can know my bestshare ? It's so useful to me and I don't find this info in the Braiinos+ gui

Thanks

Braiins OS seems doesn't have bestshare, unlike the stock firmware that you can find the bestshare under miner status.

There are two people already talk about this to add it on their GUI but until now they didn't add it yet.

Thank you very much for these informations !

IMO the best share info is the only missing thing with Braiinos+. Hope they will include it one day !

[Artemis3]

As i said before, the best share should be returning in the next version, you could see it in the UI before the 2021 release.



If you want to try the nightly be my guest. But it has some unfinished touches and breaks btctools.

Sorry I didn't saw that information !

I'm really happy to read that, thank you !

 I would like to test your firmware and to give you a feedback

[fabinhomattos]

Where should we add --fan-temp-hot and --fan-temp-dangerous parameters?

Any idea how to actually use this command?

--no-sensor-scan

I'm willing to bet they can be defined in cgminer.conf, waiting confirmation Confirmed:

It can be used when launching cgminer, or within cgminer.conf.

Just edit cgminer.conf and add it as any other cgminer option:

it's both like with any cgminer option...

It is best to put it into the config file /etc/cgminer.conf...

the options are standard form for cgminer

"no-sensor-scan" : true will work

disabling temperature sensor scanning  when can it be useful?

when your sensors are broken

I want to disable the verification of the temperature sensor of my s9, because there are several with problems, up to the temperature error 15, that the board does not work... anyway... I only want that... then I read here that there is a path that you change cgminer.config something similar... but how do I get to this path, what program do I use, how do I access it... I use braiins os+, but I would like to know how to do this for braiins os too... because the sometimes i use it. and I change this in the image before playing to the machine, or after the machine has already gone up and is running... anyway. help me please.

You are looking at obsolete information, anything from 2019 or earlier is no longer applicable to the modern version made with bosminer (cgminer was dropped and replaced with bosminer which was made from scratch using the rust language).

This feature is currently located in Miner > Configuration:



Which is written to /etc/bosminer.toml

know how to tell me how I configure so that in automatic power mode, that the hash cards do not exceed 8.8v, as I see that sometimes the cards reach 9.2v and this is melting the cables. i would like to limit it to 8.8 or 8.6 in autoscan... another question, i want to solve this chip temperature checking issue. would you know how to help me as I disable this check so that the boards work even with bad temperature chips. thanks

[Artemis3]

You do not have this level of control. You can only indirectly affect those voltages by changing the power limit, the autotuner decides accordingly.

Weak boards that are starting to fail, will bump the voltage up because otherwise they don't hash, this is a process that can sometimes be catched early, typically when a chip is starting to fail.

None of the manual values do nothing with Autotuning enabled.
Braiins OS has no temperature checking, it will work without sensors. If none of the hashboards sends temperatures, the fans will be set for 100% unless set manually. Your questions are answered by using the firmware, use the sd card.

This is the only firmware that can run directly from the sd card without installing, if you don't like it just remove the sd card.


** SD method try before install ** (use this for testing few miners)
- Download the image for the micro SD (max 16g) card:
-- (S9) https://feeds.braiins-os.com/21.04/braiins-os_am1-s9_sd_2021-04-29-0-52331c5f-21.04-plus.img
- Flash the image from a pc (with BalenaEtcher, Rufus or dd)
-- (S9 only) move jumper jp4
- With the miner turned off, insert the micro SD card and turn it on
- Enter the miner with a web browser (find the IP with bos-toolbox listen+ip report button, or AngryIP/Nmap)
-- (Optional) Install to NAND from the System menu
- Turn off the miner
-- (S9 only) return the jp4 jumper position
- Remove the micro SD card

Hi
I just got my first Antminer S9. It is a 2019 model.
I'm eager to try out Braiins OS+. I read lots of good about it.
However, the quick start documentation is quite confusing and contradictory. In the section RUNNING STOCK FIRMWARE RELEASED IN 2019 OR LATER it first talks about the SSH being locked with the newer models.
It talks about installing Braiins OS to 2019 stock firmware with BOS Toolbox. Clear enough.
But then it goes on to state that devices with 2010 stock firmware CAN ONLY be installed with an SD Card.
I would prefer to install with BOS Toolbox but I don't know if it will work. Can I use it or do I have to use SD card?
Please fix this in the documentation as it is contradictory and confusing.

Why don't you just try ? Wouldn't be more easy than wait the answer here ? Nothing risky to try to change your firmware to be honnest.

Ok thanks SerbianFarm. I have no experience changing firmwares and am a little scared of the process. I had the idea that doing something wrong in the process could brick the miner.
thanks for the quick reply.

[Artemis3]

As i mentioned before, with the sd card you don't need to change anything, You can just test it without installing.

The toolbox needs either 2018 or earlier, OR 2019 the latest version because the unlocker won't work with early 2019, only late 2019.

Braiins OS+ 21.09 release: new features and beta for S19, T19 & S19 Pro
Braiins | pool, firmware & protocol

• Major release that overhauls the web interface, adds languages and features
• Early access for beta testers of S19, T19 & S19 Pro - see the dedicated section below

New features for all models:

• [feature] new web interface, with responsive design (mobile ready), dark mode and multi-languages support (ES, RU, FA, ZH)
• [feature] firmware running from SD card now support upgrade and auto-upgrade (same as firmware running from internal NAND memory)
• [feature] firmware automatically pauses mining if there are no online pools in your settings, minimizing the power consumption and will automatically start mining once at least one pool comes online
• [x17 specific  feature] Improved Model Detection functionality, to cover situations where all 3 hashboards have invalid EEPROMs from a different model. Scenario: you have a second hand S17 and the previous owner has rewritten the hashboard EEPROMs with T17e profiles

Known Issues:

• Kaspersky Antivirus may block the web GUI
• [S9] Wrong DPS default minimum power limit value = 100 W
• [x19] Sometimes invalid Power usage data
• [x19] Inconsistency in data shown in GUI Dashboard
• [x19] No chip temperature in GUI Dashboard

S19, T19 & S19 Pro - EARLY ACCESS

• Access to early beta is possible only if you swap your x19 control board for an x17 control board. This is due to locked x19 control boards. Installation details can be found below. An alternative installation method will be available for the official public release.
• This is an early beta to gather feedback. We appreciate any enthusiasts taking part to provide feedback via our Help Desk.
• Not currently supported: S19i, S19j, S19j Pro, S19+ so signup for updates here!

Installation:

EARLY ACCESS Antminer S19, T19 & S19 Pro: to run the firmware on x19, replace the x19 control board with an x17 control board. Note that the C49 control board (used in S17/Pro and T17) has smaller dimensions and the cables might not be long enough to reach the hash boards of the x19. Continue with the standard x17 installation method (SD card method) or update the firmware to 21.09 if Braiins OS+ is already installed on the control board. The 21.09 firmware will detect whether it is being installed on an x19 (with x17 control board) model. You can always revert back to stock firmware for x17 on that control board. An alternative installation method will be available for the official public release.

For new installation from Stock firmware (x17 & S9): see documentation.

Automatic update:

if your current Braiins OS+ has auto-update enabled your device will be updated automatically.

Manual update:

• You can also update using the web interface: flash the firmware by navigating to top-menu > System > Backup/Flash Firmware > Flash new firmware image >
  S9 (click here to download)  or x17 (click here to download)
• Update in single/batch mode using BOS Toolbox Install tab > type your device IP address (or IPlist.txt) in the Miner(s) field and type the device password and click Start button.

Have you fixed the problem with the S9 version that does not shut down the miner when internet connectivity (or all pools down) is lost? My rigs just mined nothing - producing heat - for over two hours today when the power supply for a network switch went belly up.

As they are in low power mode and sound proofed enough they are 10 ft away. I can hear them, but not be distracted. For the whole 2 hours the fans kept going and when I checked hot air was coming out. After replacing the power supply the network connection resumed. I waited almost 10 minutes and they still had not reconnected to a pool. So I had to reboot them. This is not good at all. They have static addresses.

Another thing to fix: When enabling / editing pools it wants to do a warm start and do the tuner testing hash rate routine, this using 5-10 minutes to do so. Unless the power setting is changed I can't think of any reason for this.

And lastly. Please make it so I can save / restore configurations to my computer. Just like the original Bitmain software.

Thank You.

Hi Guys,
I am a long time larkar and a very small miner since 2016. I am facing a strange problem with BrainOS+. I have a s9j which is part of my small Brain os s9 farm that mines in slushpool. I installed brain OS+ in this s9j using a sd card and then permanently into NAND. I am noticing for last few days this S9j always mines at 1200 watt power limit with auto tuner on. No matter what I change in configuration for my s9j in brain os + or through the brain os +  farm, it automatically reverts back to a particular configuration having 1200 watt power and stratum v2 as the only connection. There are other s9 having brain os in my brain os farm. The other s9 respond to changes to device configuration and changes through brain os farm configuration but this particular s9j does not. It was not like this before. I had been able to configure this s9j directly and through the brain os farm. It had run on 800 limit, 850, 900 and 1200 limit before. It had run on stratum v1 and v2 before. But somehow for last few days it is behaving as if a particular configuration with 1200 watt limit is permanently etched into its memory. Please help.

[Heathen23]

The issue got resolved. I am not sure why suddenly the s9j decided to be obedient to the farm and switched back to 800 watt like other s9s in the farm.

[Scortexx]

The issue got resolved. I am not sure why suddenly the s9j decided to be obedient to the farm and switched back to 800 watt like other s9s in the farm.

For me this S9j is not that good when using Braiins OS+, I have one in my mini farm and the rest are S9's. With autotunning all S9's do above 15.5 ths and the S9j does 15.1 ths for example. I have one S9 that does 16.3 ths with power limit od 1400 W. All miners are set to 1400W, autotunning on, temeprature auto, and fans go high and low all the time, which I found normal as the temperature is gettinf higher, the fana keep going to higher RPMs
My question would be, why does this go up to 16.3 ths on 1400W and other 15.5 on 1500W limit!? Did anyone tried to mess up the wattage and frequencies to get more THs? Does this depends on the state of hash boards? I preffer a low power modes but I am setting this up for my friend and he wants to mine as much as he can, for now it doesn't matter how the miners get.
All 4 were on different firmwares, so if anyone needs help with installing the Braiins OS+ on their S9's, I will gladly help!

[Artemis3]

Because its not linear and sometimes more gives less, so you have to experiment values both up and down. I would advise your friend to focus in efficiency rather than speed, and yes, each hashboard is unique because the manufacturer throws a bunch of chips with different performance yield and let their (quick) auto tuning reach the advertised speed regardless of the chips actually being able to be more efficient which is what Braiins OS+ discovers after a far more exhaustive process.

Start with the default and try lowering values in 10, 20 or 50W steps. Don't bother going up unless you are doing immersion, its not worth it. The theoretical limit for the APW3++ before dropping its efficiency is 1496W. Its never good to run at the borderline, any little power fluctuation will make it go over it.

Remember, in the end better efficiency brings more profit than brute speed.
