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

[Artemis3]

I tried bos-toolbox install -p password 10.10.10.10 but I get this error:

Code:

[2021-02-28 20:40:13] INFO:Attempting unlock host on 10.10.10.10 with AntPwn v3...

Do you maybe know what causes this error?

This error happens with 2019 firmware before July. Just upgrade your miner first.

Does anyone have the braiinos link for dragonminer T1? I have 5 units and I would like to install it since I have it installed in antminer s9 and it is very efficient

T1 support was dropped in 2019, its not recommended.

Guys does anyone know how to properly roll back from this version (Tue Jul 30 20:37:39 CST 2019) to this (Thu May 16 15:51:14 CST 2019) version? i got error while trying to flash it.

Hello ,

Wow, it's been awhile. Would like to say what's up to everybody! Started this whole mining thing around 16'-17' for awhile, life changed and miners got disconnected. Few months ago, decided to check on some old pools, that mining I did years ago actually made me some coin. Decided to sell my old S3+, picked up a S9i at a pretty good price compared to prices now.

Ok, i see users stating they are getting something like 10.5TH@755W on various forums out of Braiins OS+ with S9's. Could someone please explain how? For example, Set my Power Limit to 800W, settings are default w/AutoTuning & ASIC Boost Enabled. I get 8.3-8.5TH@755W. Settings presently are 10.42TH@993W. Looking for any links or info to learn more about low voltage mode and how to obtain those settings mentioned above.

Thanks for any info and knowledge.

Every miner, every hashboard performs differently. Specific power limits will provide different results even with identical models, this is because the chips themselves all have varying qualities, and the autotuning algorithm will find out the best way to use each of them, which is why the process takes its due time.

So if you see someone with an excellent result, it doesn't mean you will get the exact same result using the same value. Especially if the other person has, for example, the S9j 14.5 and you have a vanilla S9 13.

The only thing you can do is experiment different values to find the best efficiency your specific miner can make. You have to wait for the Tuner Status to show Stable before measuring.

Hi.

I'm running BOS+ from SD card on a single S9 13,5 THs version.

I've tried different Autotuning settings and so far it seems to run most efficient (taking into count profability) at 1000 W setting (930-935 W measured at the wall) and then mining ~12,15 THs.

Edit: Obviously always tuning until it shows "Stable"

I have the miner in a not yet insulated garage and outside temp is app. 5^oC.

I've noticed that the miner performs differently when rebooted at different temperatures. Usually it performs better at warmer temperatures.

Because of this I'm wondering if it would perform even better if i rebooted it and retuned at a higher temperature. However when once tuned at 1000 W the settings are stored and the only way I can get it to retune is to choose another W-setting.

Is there a way to reset the tuning at 1000 W or is the way to go to retune at 999 or 1001 W?

It has now been tuned at 100 W-steps from 800-1600 W and I would not like to reset all autotune settings at once.

Regards.
Steff

To delete the profiles just do the following from the miner's UI:

Quick Actions, stop bosminer
System > Software, install luci-app-commands
System > Custom Commands
  Configure > Add
      Name: Delete profiles
      Command: rm /etc/bosminer-autotune.json
  Dashboard > Run Delete profiles
Quick Actions, start bosminer

Of course you could instead just ssh into the miner and do the same:
ssh root@IP_ADDRESS '/etc/init.d/bosminer stop && rm /etc/bosminer-autotune.json && /etc/init.d/bosminer start'

Or do it in batch using the bos-toolbox:
bos-toolbox command iplist.txt "/etc/init.d/bosminer stop && rm /etc/bosminer-autotune.json && /etc/init.d/bosminer start"

Isn't it great to have a proper OS running in your miner, rather than that Xilinx crud everyone else just modifies because they are too lazy to do any better?

braiins has shown to work better for the 10 s9's and the  one testing s17. That I loaded braiins to.

eventually I will place more gear on braiins.

I have been neglecting sha 256 asic gear and mining due to the gpu/eth boom.

I can still get an occasional gpu close to msrp. Mine eth and swap to cash /BTC  

I Just did that this morning converted 600 in eth to 300 in btc and 300 in cash

So my attention is grabbed by gpus more than asics. Due to superior profits available to gpu miners.

I like braiins and eventually will likely end up with most of my asic gear using it.

Hi Artemis.

Thanks a lot for this info. I'll try it out when it gets a little warmer outside.

Hello,

A small question regarding the maximum power of 1600W for an APW3++ power supply for an S9i.
I have one of my S9i that has a card out of order, so I unplugged it.
If I leave the Braiins OS+ configuration on 1600W, will I have a maximum of 800W in each card or the software will automatically calculate to put only 533W per card?

Thanks
Mickael

anyone else have trouble with brains and Awesome miner?

If you read Bitmain's documentation, you will notice they say efficiency is good up to 93.5% load, then it drops very fast. This means 1496W should be the theoretical MAX value.

Switching PSUs should not be run at full capacity for sustained periods of time. Safety margin is in order. Commonly with computers or electricity in general, people leave 20% margin, which for 1600W means 1280W.

In electricity (and electronics) you don't want to be running things at their max ratings, always leave a safety margin. For this reason the default comes at 1420W which is meant for the APW3++ that many S9s use.

Also, it is a known fact that Bitmain asics are more efficient a slower speeds, which is why many people use values near 900W for the power limit value, which also allows it to run at 110V and a single fan.

To answer your question, the answer is no. Each hashboard will always get 1/3rd (or slightly less) of the specified power limit value, so you don't need to be changing this value if you have less boards enabled or connected.


And now an announcement:

Braiins OS+ Nightly Release for X17 Devices
What's new:
+ the tuner has been significantly improved to ensure faster convergence and more stable tuning configurations. Old tuner profiles are kept, but ignored.
+ for safety reasons, the fans are running @ 100 % during the tuning phase. Once finished, the user settings are used
+ BOSminer will keep on restarting underperforming hash boards instead of switching them off completely. The delay between restarts exponentially grows from 5, 10, 20, etc., up to 180 minutes if the hash board performance doesn't improve. (In some cases, a simple restart is all that's needed for the underperforming boards to begin hashing properly.)
+Dynamic Power Scaling now works even with Manual Fan Control

How to install the nightly build:
1. Download the new BOS Toolbox from here:
Windows - https://feeds.braiins-os.com/toolbox/latest/bos-toolbox.zip
Linux - https://feeds.braiins-os.com/toolbox/latest/bos-toolbox

2. Install/Update Braiins OS+ with the following command:
Windows - bos-toolbox.bat install --nightly list.csv
Linux - ./bos-toolbox install --nightly list.csv

Whats the latest release for the S9?

My current firmware is dated 27/11/2020.

Auto Update is ticked and I've tried "bos-toolbox update" but any method I try says that its the latest firmware, but I've seen listings of S9s on ebay with a different GUI which I'd like.

[Artemis3]

For S9 the current latest "major" is 2020-11-27 and latest "minor" is 2021-04-29 which for most users is just a small UI update. It does add support to the Braiins OS Manager if you want to test it.

The Minor releases need to be upgraded or installed manually rather than with the usual built in upgrade methods.

[gt_addict]

So thats a case of switching the jumper and loading to an sd card and writing to nand again?

[Artemis3]

You can upgrade manually from the miner itself, use this file in System > Flash Firmware:

Thanks Artemis, I tried that but obviously the wrong file lol. I didn't realise it was the one for the arm controller.

EDIT:-

Just flashed it. Works perfectly. Thanks again.

any one running s17s I have a s17 running and used tuner  vs my settings

I am trying to determine how long tuner tunes.

also what are people getting with the tuner set to 1425 watts


I am at 1 hour and 11 minutes and around 42 th at  1425 watts setting


I have this firmware

You are running a version too old, the x17 family has gotten many updates and bug fixes, in the following days should come another release, but you can try enabling nightly feeds (only if installed into NAND, SD image here) in the meantime.

The latest nightly is 2021-06-10.
