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

[Artemis3]

Try download this package https://feeds.braiins-os.org/am1-s9/firmware_2018-11-27-0-c34516b0_arm_cortex-a9_neon.ipk and install it from the web ui or via ssh:

Code:

wget https://feeds.braiins-os.org/am1-s9/firmware_2018-11-27-0-c34516b0_arm_cortex-a9_neon.ipk && opkg --force-downgrade install firmware_2018-11-27-0-c34516b0_arm_cortex-a9_neon.ipk

The latest firmware is supposed to be able to control the fans, did you check they were set correctly? Also see if you have set chip voltage and frequency settings in that particular miner and try if letting it auto adjust works better.

The issue was indeed broken fan. I can confirm, that temperatures in latest BOS are reported correctly and miners are restarting once temp2 hits 95C. Thank you for your help with downgrade command, maybe someone else will find it useful.

This piece of news from the Braiins OS Telegram group is of interest for all the water/liquid coolers out there:

• the new update allows running without fans completely
• but it will take us about a week to release

So, no need to pwm emulate or use cheap fans without blades anymore

Good day,
I need my miner to run at 700 MHz during the night and 500 MHz dring the day.
Is it possible to make a time scedule like this?
If not, may be is a good idea to be implemented in the next version.
I have a cheap energy during the night I believe a lo of miners will use it in this way.

u can do that with task schedule,
read couple of posts before  im sure someone explained how u can do that

As I posted this earlier, crontab is your friend ...

Add 2 cgminer.conf with your desired configs

Example:

Code:

/root/cgminer.conf.500 
/root/cgminer.conf.700 

Then edit crontab and set it to copy them before reload cgminer.

Code:

crontab -e

Code:

0 7 * * * cp /root/cgminer.conf.500 /etc/cgminer.conf && /etc/init.d/cgminer reload
0 23 * * * cp /root/cgminer.conf.700 /etc/cgminer.conf && /etc/init.d/cgminer reload

Googlefu has failed me.  Is there scheduled mining support?  When Summer hits I'll have to deal with Smarthours, sometimes the kWh cost will hit 0.44/kWh and I'm often not at home to unplug the systems during these events. And I'm forgetful.  I'm looking for some way to tell the S9s to stop mining and use just minimum power for about 5 hours a weekday.  I usually have a day's warning on when high cost events will hit.

Try the crontab tricks mentioned before, but instead of changing speeds, use an invalid pool so it never gets any work to do...

Try downclocking to 500~600mhz and see if it remains stable. The temperatures are fine? Also you could try switching with another PSU just in case that one is misbehaving.

Thanks mate

Will try to swap the PSU and see how it goes.

Tried as low as 200mhz and voltage to 8 (wont let me go lower than and it keeps rebooting, the only way I can work on it is to stop cgminer from ssh as soon as miner starts.


It was PSU problem, but funny thing is swapped two miners PSU and both are working fine now.

... It was PSU problem, but funny thing is swapped two miners PSU and both are working fine now.

Then it could have been a wire/connector issue, glad it is working fine on both miners.

NEW RELEASE: Braiins OS Cobalt is here with February release!

Current upgrades/fixes:

• Dragonmint T1: support for G29 revision of the control board (no SD-card slot)
• Dragonmint T1: web interface now allows configuring full range of frequencies (120 MHz - 1596 MHz) and voltage levels (1-31)
• Antminer S9: new configuration option allows disabling temperature sensor scanning (--no-sensor-scan). I2C scan log is now being stored into a separate file: /tmp/i2c_scan.log
• Antminer S9: support for ADT7461 temperature sensor that appears to be used on some hash board revisions
• [fix] 15m and 24h hash rate shows up only if the full time period of hash rate data has been collected
• [fix] enabled/disabled indicator for Asic Boost now works again in the overview status page
• fan control now has a new option --min-fans that specifies the minimum amount of fans that have to be operational (defaults to 1). Setting the option to "0" results in skipping the check for working fans.
• temperature limits are now configurable via configuration file. The two new configuration options are: --fan-temp-hot and --fan-temp-dangerous. These options effectively override the temp limits in temp-def.h

Visit braiins-os.org for more information and downloads.

Any feedback is appreciated!

=====

Say goodbye to backdoors, closed systems and “hidden features”. Braiins OS is completely open-source and transparent.
The code is available to anyone to understand, audit and verify. And of course, you are invited to build on top of it.

[papampi]

Thanks a lot for the update

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

[Artemis3]

This time there are not many more details, but here it goes in case something was missed:

2019-02-21-0

All mining hardware types

    [feature] temperature limits are now configurable via configuration file. The two new configuration options are: --fan-temp-hot and --fan-temp-dangerous. These options effectively override the temp limits in temp-def.h (They actually are: --fan-dangerous-temp and --fan-hot-temp).
    [fix] 15m and 24h hash rate shows up only if the full time period of hash rate data has been collected
    [fix] enabled/disabled indicator for Asic Boost now works again in the overview status page
    [feature] fan control now has a new option --min-fans that specifies the minimum amount of fans that have to be operational (defaults to 1). Setting the option to "0" results in skipping the check for working fans.

Antminer S9

    [feature] new configuration option allows disabling temperature sensor scanning (--no-sensor-scan). I2C scan log is now being stored into a separate file: /tmp/i2c_scan.log
    [feature] support for ADT7461 temperature sensor that appears to be used on some hash board revisions

Dragonmint T1

    [feature] support for G29 revision of the control board (no SD-card slot)
    [feature] web interface now allows configuring full range of frequencies (120 MHz - 1596 MHz) and voltage levels (1-31)
    [feature] transitional firmware for Dragonmints T1 with G19 control board is no longer provided. See the documentation for details.

It is important to highlight that disabling the fans (setting to 0) means people with liquid cooling no longer need fans attached or dummy hardware emulation. Also the Dragonmint T1 with G29 control board (256m of ram) should work...

Be very careful with those speeds and voltages, just because you can doesn't mean you should. There is no hand holding here and you can easily burn your asics when overclocking or disabling the fans. You can also damage your PSU by overloading it when overclocking.

With great power comes great responsibility, this is the freedom of free open source software.

Any idea how to actually use this command?

--no-sensor-scan

[Artemis3]

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

[sarcheer]

With this new cgminer option added, I can now how full use (no temp sensors) of my R4 with Braiins! Everything else works, and I'm now running at 630 freq, 9.1v, and 9TH.
