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

[PassThePopcorn]

The error you posted it's trying to upload the s9 firmware, use the t1 firmware instead.

LOL, im so dumb, thanks for the advice, now seems that it goes, is "Restarting" for a couple minutes.

[Cryptomorpher]

Hmm i would guess /etc/init.d/cgminer stop

But why?

Im playing with cgminer source code and need to replace binary. So first I have to stop it.

Can I upload this through the braiins firmware upgrade gui to refresh braiins?

To use web upgrade you should use web image

braiins-os_am1-s9_web_2019-02-21-0-572dd48c.tar.gz

To upgrade the Braiins OS firmware to the latest version, upgrade the package called "firmware" (yes, thats its name). You can do that from the web UI (first refresh packages), or from SSH with:

Code:

opkg update && opkg upgrade firmware

You can follow this procedure every time there is a new Braiins OS version available.

Would it be possible (maybe in future releases) to control the startup fan speed?

And instead of using no-sensor-scan to ignore all temperature sensors, would it be possible to just ignore the sensors on boards/chains with problems?

I asked about this, and there is good news for you:

"would it be possible to just ignore the sensors on boards/chains with problems?"

I think this feature request would be to disable sensors per board (chain) instead of the whole miner.

that's implemented for the upcoming release

Not about the fan of course. There is nothing you can do when you are powering up a fan you get full power to it, until the controller boots and orders it to slow down. The only way to solve this would be with a hardware solution, such as feeding 7v instead of 12v for 1min or such...

That is very good news indeed! Thanks for asking!

Ah, I see. So it's not a setting, but fans getting the full 12v until the controller kicks in.

Well, maybe I will just disable the fans altogether and look for an other way of cooling. In my case noise is the biggest issue.

You can adjust the fan speed on default s9 firmware but the problem you can't bypass the temp sensor if you force to bypass the temp sensor it may lead to overheating and it will end up dying fast.

If you still want to know how you can follow this method from here Solution for ANTMINER S9 FANS SPEED Up & Down every 20 Seconds.

Or use a soundproof box to reduce the noise image below.

[Vietjan]

I disabled the fans and connected the miner to the air extraction system of the building. Also swapped out the APW7 for a normal desktop PSU. The miner is almost completely silent now.

With Braiins I underclocked the miner to 325 MHz, and I'm getting a hashrate of 6.5 / 7 Th/s with temperatures of 80 / 85 degrees Celcius. (When things heat up during summer I can go as low as 200 MHz.)

When playing around with the MHz I also noticed that the miner will still shutdown when --fan-dangerous-temp is reached, even when using --no-sensor-scan. (So a failing air extraction system will luckily not destory the miner.)

I'm very happy with Braiins, because before all the boards in this miner were considered to be dead because of the problems they had.

A wooden box with sound insulating fabrics inside works better, coupled maybe with sound insulating ducts attached to the box (NOT the miner).

Fan speeds can be adjusted with Braiins OS, but he was complaining about noise at start time, before the firmware has any chance to do anything.

Does it work on the s9 hydro?

No it doesn't as at 25th May 2019. I flashed my S9 hydro with normal S9 asicboost, the new one with the .sig. signature image. Now it's bricked because Bitmain will not write a .sig. version for the S9 Hydro AND, the image/firmware that is in there blocks any SSH or none .sig. files.

There is only one firmware for the S9 Hydro anyway here --> https://service.bitmain.com/support/download?product=S9-Hydro (scroll up if you can't see it!)

The S9 Hydro is not just a water-cooled S9. It has a different controller board and uses 24 pin ribbon cables as opposed to 18 pin ones on S9's.

[Artemis3]

You might get support at a later version, so don't lose hope. I haven't seen any Hydros, Does it still have the jp4 jumper (or switch) that would let it boot from an SD card?

Maybe the S11 or newer use a similar controller?

[quser1]

I am wondering if someone can give me a hand. I am wanting to run my S9 at 681,731,725-8.8,8.9,8.7 from 11am to 10pm, then 793,825,793-8.9,9.0,8.8 from 10pm to 11am. I am not sure how to wright it in corntab. Can someone help me so that I don't mess it up? Thanks in advance. Q

[rfsimoes]

Hi all, sorry I'm a noob in linux.

In what file should I put the --min-fans setting? cgminer.conf? If not what is the correct file and path to it? The same question goes for "--fan-dangerous-temp" and "--fan-hot-temp" settings. What is the exact correct syntax usage for this?

Also, I tried to find "temp-def.h" file and did not found it via ssh console find command!?

Thanks.

Probably a variation of this,

Just make copies of cgminer.conf with your desired configurations and switch them accordingly.

All you need to do is run a script at the desired time to shuffle your config files.

[quser1]

Thanks for the responce but it seems that one of the admins edited my post removing the quoted post. This is what I had quoted:

Add 2 cgminer.conf with your desired configs

Example:

Code:

/root/cgminer.conf.500 
/root/cgminer.conf.750 

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

Code:

0 7 * * * cp /root/cgminer.conf.500 /etc/cgminer.conf && /etc/init.d/cgminer reload
0 23 * * * cp /root/cgminer.conf.750 /etc/cgminer.conf && /etc/init.d/cgminer reload

Dont know if you need to stop cgminer before copy new config or not, if so you can do this:

Code:

59 6 * * * /etc/init.d/cgminer stop
0 7 * * * cp /root/cgminer.conf.500 /etc/cgminer.conf
1 7 * * * /etc/init.d/cgminer start
59 22* * * /etc/init.d/cgminer stop
0 23 * * * cp /root/cgminer.conf.750 /etc/cgminer.conf
1 23 * * * /etc/init.d/cgminer start

So I want to do this in "scheduled tasks", But I want to make sure that I have it typed right. Can you lend any assistance with that? Doing it the way you sugested will require me to do something every day (as I do now). I want to be able to set it and let it run.

Thanks,
Q

[Artemis3]

You don't need to stop cgminer before copying the file, just copy it then restart it. If you leave it like that, you are going to lose 4 minutes of mining everyday.

The point of putting your commands in cron, is so you don't have to do it everyday.

Only once you are going to copy the files, you could possibly do it by hand if you recognize where the settings go, but setting them in the ui  then copy that configuration works.

As long as you have both config files made, manually or by ui.

[quser1]

Right now I am using the UI to do the change manually and yes I loose about 4 min a day but the gain outweighs the cost. Correct, the point of using the Scheduled Tasks is so that I don't have to do it myself every day. My problem is that I don't know the syntax that is needed to accomplish what I would like to do. I have the basic understanding with the previously quoted, but I don't have the specific.
