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

if I set the fans to the required fans to 0 or enable "immersion mode" then it is not good either. The fans start repeatedly from 0% to 100%.
It behaves similarly with last firmware.
Why started restarting on automatic mode wnen i change slower
fans ?? does it have any solution?
would it help install third-party firmware?
Thank you

Change the minimum number of required fans to 0 or enable "immersion mode" if you have the latest version. Leave it in auto.

Did you guys ever get around to supporting the s9k miner?

S9k, S9se, S9hydro are not supported (it doesn't work, different control board).

Currently only supported:
Bitmain Antminer S9, S9j, S9i; S17, S17pro, S17+, S17e; T17, T17+, T17e.

Development pipeline:
MicroBT Whatsminer M20s.
Bitmain Antminer S19 family.


Copying the profiles isn't needed, all the power limit profiles get saved in the same file, and are not set in stone either, it can change over time later.

Just switch the power limit value, like this:


0 7 * * * sed -i 's/psu_power_limit = 1400/psu_power_limit = 900/' /etc/bosminer.toml && /etc/init.d/bosminer restart
0 19 * * * sed -i 's/psu_power_limit = 900/psu_power_limit = 1400/' /etc/bosminer.toml && /etc/init.d/bosminer restart


There is no need to restart cron, changes made to System > Scheduled Tasks take place immediately.

Also be sure to not delete the existing two lines as they are used to check for updates, you have to ADD the new lines.

And if I only want to run the low power task 900W? what will be the command?
I would run the high profile by hand.

The same command, use ssh or the bos-toolbox:

bos-toolbox command -o -p YourPassWord iplist.txt "sed -i 's/psu_power_limit = 900/psu_power_limit = 1400/' /etc/bosminer.toml && /etc/init.d/bosminer restart"
ssh root@ip.ad.re.ss "sed -i 's/psu_power_limit = 900/psu_power_limit = 1400/' /etc/bosminer.toml && /etc/init.d/bosminer restart"




Hi, I'm using the command:
0 5 * * * sed -i 's / psu_power_limit = 1590 / psu_power_limit = 1160 /' /etc/bosminer.toml && /etc/init.d/bosminer restart
This is working properly.

I replaced the fans with delta Delta AFC1212DE 12038 12cm 120mm DC 12V 1.6A, 4500rpm
With these, the miner restarts every 20 seconds immediately after the start.
When I set the fans to manual restarts they stop.
How to solve this, I would like to have fans at automatic speed.

Or how to modify the command to change the fan speed and psu_power_limit. The one I use.

Thank you

Hi, is there any way to automatically switch performance profiles in Braiins OS at any time? I need him to run at full power at night and only low power during the day. I searched everywhere and didn't find it. Thank you

You need to follow these steps (note that numbers are examples, change them to your proper numbers):

1. Set the tuner power limit to 900 and let the device tune and gets stable

2. SSH to the device and run the command below:
Code:
cp /etc/bosminer-autotune.json /etc/tune900.json

3. Now back to the device set the tuner power limit to 1250 and let it tunes and gets stable

4. Again SSH to the device and run the command below:
Code:
cp /etc/bosminer-autotune.json /etc/tune1250.json

5. log in to the Braiins OS+ web interface and navigate to System > Schedule Tasks

6. Copy and paste the following command to the text area and save it.

Code:
0 9 * * * /etc/init.d/bosminer stop && sed -i 's/psu_power_limit = 1250/psu_power_limit = 900/' /etc/bosminer.toml && cp /etc/tune900.json /etc/bosminer-autotune.json && /etc/init.d/bosminer start

Code:
0 21 * * * /etc/init.d/bosminer stop && sed -i 's/psu_power_limit = 900/psu_power_limit = 1250/' /etc/bosminer.toml && cp /etc/tune1250.json /etc/bosminer-autotune.json && /etc/init.d/bosminer start

7. SSH again to the device run the command below:
Code:
/etc/init.d/cron restart

8. Set device time zone to your proper time zone

9. The device will work 09:00 to 21:00 with 900w as PSU power limit and 21:00 to 09:00 with 1250w as PSU power limit.

Thank you for your help.
And if I only want to run the low power task 900W? what will be the command?
I would run the high profile by hand.

thank you very much
