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

[Guinsanity]

Theres a way to make braiins auto restart the asic when not hashing?

I think you can't do that auto restart the miner when not hashing? you can set the miner to auto restart but you can't set it to auto restart when the miner is not hashing.

There is a method through SSH to set the miner auto reboot every 3 hours or any time you want to reboot the miner I don't know if Braiins OS has this feature but you can do that in default firmware of s9. Source from here https://bitcointalk.org/index.php?topic=4720967.0.

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.

Cron syntax is rather simple, you can learn it by using this web page: https://crontab.guru/

Could someone please tell me - is it possible to use cgminer on braiins-os in --load-balance mode and mine for 3 pools at same time?

Ok I have looked that over, but I don't think it is giving me what I need. It has no explanation as to what I need to put into cgminer.conf or how to wright the code to get it to run properly. All that link does is tells me how to set up the timing.

I haven't tried it but this option appears to be available. Why don't you just try it?

I would bet something like "load-balance":true in cgminer.conf would do.

I tried. It just mines for the first available pool and doesn't mine for the others. It keeps connection to the rest of pools but there is no accepted blocks.

New version out!

2019-06-05-0
All mining hardware types
    

• [feature] YES, we have a new logo that is consistent with the new Braiins logo, hope, you like it ;-)
• [feature] the IP report button feature now broadcasts a UDP datagram compatible with the original S9 factory firmware
• [feature] the miner now stores the reason of the last cgminer exit/failure in /tmp/cgminer_quit_reason. The miner status page now presents the actual reason along with a confirmation button to clear the last failure status
• [feature] fix web status data loading when connecting to miners in remote locations with considerable latencies
• [feature] universal SD card images - each SD card image tries to detect device MAC address from any firmware image that is present in NAND flash. This simplifies using the same SD card image on multiple devices without the need for manually generating editing uEnv.txt on each card
• [feature] it is now possible to install bOS into flash memory from a running SD card - see the docs for details
• [feature] increase stratum connect() timeout to 3 seconds to prevent harassing stratum servers to early when probing all IP address for a given URL
• [feature] attempt to perform opkg install firmware on bOS instance running from SD card now visibly tells the user that this is not a supported operation (= you should obtain a new SD card image and write it to your SD card)
• [feature] TUN/TAP module is now part of the base system as we cannot use upstream modules due to custom kernel. These can be useful for OpenVPN
• [bug] #xnsub support for NH stratum extension has been fixed
• [bug] a few memory leaks in bmminer and cgminer API have been fixed

Antminer S9
    

• [feature] there are 2 new options: --disable-sensors - the mining software acts as if there were no temperature sensors found. That is fan would be running at 100% unless set to some manually override value --disable-remote-sensors - mining software only takes temperature measurement from the hash boards and doesn't try to measure temperature on the mining chips. The actual mining chip temperature is being estimated as hash board temperature plus some empirically set offset (15 C)
• [bug] fix support for non-asicboost pools by eliminating mining.configure in case the number of configured midstates is 1 (AsicBoost disabled)

6/5 installed on farm, smooth install, working great. Thanks Braiins!

Image SD boots right up. No txt file needed.

TUN/TAP module is now part of the base system as we cannot use upstream modules due to custom kernel. These can be useful for OpenVPN

Using a VPN to mine WILL increase stales and WILL increase the risk of the pool losing blocks.
I've no idea why anyone would put that in a firmware.

[bug] #xnsub support for NH stratum extension has been fixed

This is not not part of cgminer for a reason - it's a MAJOR security risk for the miner.
It is NOT in the master cgminer git.
Which ALSO means that the exact source code used MUST be provided if ANYONE using this, requests it.

I have a few miners that only reported one board temp sensor with december firmware. With 6/5 firmware there are no temp sensors seen on  any boards for a few miners Fans are running 100%, staying cool. Before I could use sensor on one board to control fans. Any way to make that feature act as before?

Also, have had a few controller boards with braiins install from seller that had no ssh access. Enabled dropbear on system->administration to get ssh access.

I use no-sensor-scan when it takes 30 min to boot doing the scan. If at least one board sensor is working it will control the fans.

Did the install bOS into flash memory from a running SD card from the gui system menu. Works great.

Swapped one hashboard showing a temp into each of 7 miners showing no temps on any hashboard.

Now the one hashboard with a temp is controlling the fan for each miner so it doesn't run at 100% .

Hi

I have been using Braiins OS & really like it.

I would like to try to improve the efficiency of my miners by underclocking my S9's

What is the best way to figure out the watts used?

Thanks

[papampi]

Use some "wall plug power monitor"

Just google it

[Triple-S]

I have been looking but I have not been able to find any that work with 240V 6-15p or 6-20p outlets.

Would a clamp meter be the easiest solution?

[philipma1957]

no  it depends on how much power you want to use.

1 s-9 can use this setup  wait for links

https://www.amazon.com/NEMA-6-15P-Power-Rated-Black/dp/B07DX9VNVX/
https://www.amazon.com/gp/product/B07M8JKLG5/

that will accept this cable

https://www.amazon.com/MarginMart-Conductor-Connector-Socket-MM682020/dp/B076J61L37/

it will do 240 volt up to 1800 watts safely

do not test for longer then 2 or 3 hours if you are over 1200 watts.

[Triple-S]

Thank you I will try this out 

[quser1]

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

I'm Still looking for help with this if anyone could lend a hand.

Thanks

Hello, I just installed Braiins OS on my s9j 14.5 Th, but in the device overview it shows device model as  s9 is it ok ?

Nope you dont need to do it every day,

Info on 1st crontab sample:

copy and reload at 7 AM:

Code:

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

copy and reload at 11 PM

Code:

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

Info on second  crontab sample:

This will stop cgminer at 06:59 AM everyday

Code:

59 6 * * * /etc/init.d/cgminer stop

This will copy cgminer.conf.500 to cgminer.conf at 07:00 AM every day

Code:

0 7 * * * cp /root/cgminer.conf.500 /etc/cgminer.conf

This will start copied cgminer at 07:01 AM everyday

Code:

1 7 * * * /etc/init.d/cgminer start

And ...

google crontab to see the options

Type in

Code:

crontab -e

And add as you wish for schedule

Braiins does not distinguish.
