If you want to aim for efficiency, you might want to try 500 mhz 8.0~8.1volts.
The goal for efficiency is achieving the highest hash rate a single watt can give, even if you end with miners doing 10TH/s but consuming 823watts.

Philipma1957 managed to obtain impressive results, you might want to find out which setting is the most efficient, but as you said, each board behaves differently.

S9s used to spend 100 watts per TH, but now with Braiins OS they can do 80. Under-clocking should not be underestimated...

Agree.
My ampere meter broke the other day so I will run more tests based on efficiency as soon as I fix it or get a new one.

Here are some tests I have done with different frequency and voltage on S9J, 14.5 TH/s
Have not get time to check power draw yet, will do soon and add them too.

As you can see some miners give different hashrate with same settings,
So your experience may differ.

I'm running auto control right now, I noticed the s9 13.5th unit I have which had "intermittent" fan spin up is gone since today.

For the fan speed, what is everyone setting their desired temp to?

I don't see any or much difference in performance from the LPM firmware bitmain released.

bOS lets you control voltages/freq/fans on a board by board basis, don't think you can do that with BM's FW.

Hi all! Trying to ssh braiins to my Dragonmint T1 (g19) and im getting this: "Error log: Unsupported miner RAM size: 250544 kB" . Any clues to what i'm doing wrong?

Does it have the SD slot? If not, you can't use it.
That error simply means 256M of ram is not supported, maybe it needs 512M?

Its not needed. But the SD card users tend to flash the exact same image (from a PC) to multiple SDs, therefore cloning the mac address.
If your devices are already using different mac addresses, don't worry.

Thanks for clarify.

I just flashed an S9J with ssh image successfully and am going to do the rest of my miners

Need a little help here,
At the end of the operation it print out "Content of U-Boot configuration" as bellow:

Where can I find "U-Boot configuration" to edit so I dont need to manually edit all the other miners after flash.

Does the mac address adjustment needed for latest cobalt 2019-01-24 to flash permanent via ssh or its only needed for sd card?

Hi guys and thanks Braiins for the great firmware!

I am wondering if someone has an idea how to perform different freq and voltages set up on a schedule?
For example to set up frequency 500 with voltage 8 at 7:00-22:59 and to set up frequency 750 with voltage 9 at 23:00-6:59.

Any ideas are very much appreciated.

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

I get error Unknown package 'firmware'.

That is strange, but i think i experienced that once or twice before. Try removing the package firmware to force a reset: opkg remove firmware

If that doesn't work, then you could follow the procedure to return to the factory firmware, and then again install Braiins OS.

In the official docs, ignore where they mention an SD card, their English isn't perfect and that wording is imprecise. That is the procedure to return the firmware in the NAND (not SD) of your miner's controller (tho it could work the same if you had an SD card with the jp4 jumper moved, i guess?:

Quote

cd braiins-os_am1-s9_ssh_VERSION python3 restore2factory.py backup/2ce9c4aab53c-2018-09-19/ your-miner-hostname-or-ip

This part 2ce9c4aab53c-2018-09-19 changes on each unit install. In Linux use tab to autocomplete the actual folder, or just look at them inside ./backup/.

If you installed it with the python script, you should already have a backup and going back to Bitmain's firmware is easy using that method.
But it is now possible to use the (current) python script to go back to a factory firmware downloaded from bitmain when you don't have a backup.

The restore2factory.py python script should have an argument that accepts Bitmain's firmware file directly, but I have yet to try that procedure.

Can it be done via ssh? Or do I have to burn image to ssd card again?
Docs are confusing for us non programmers

Upgrade the package firmware after refreshing the packages. Using the web ui:

I think it is best to reflash the SD card.

Be careful you don't end with cloned mac addresses.

Hi,

you can upgrade to January release directly via the web interface.

We have described the process step-by-step here:

you can change the MAC address from the Braiins interface in networks->interfaces->edit->advanced settings... save & reboot

For some reason my miner got a new IP from the router even though I set the same mac-address as with Bitmain FW. However we put BOS into my friends miner simultaneously (connected to same router) using his Bitmain FW-mac and got no conflicts. I can't remember if his miner got a new IP though.

Just saying that don't be to sure about the "it would have the same IP address as it had with the factory firmware" part.
