then I'll ask a mod to close it.
And why would any mod close a topic that is active and fits the board's rules and requirements? the fact that they haven't responded to your questions doesn't give any mod the right to close the topic, even if they personally tell you "We are not going to answer any of your questions" that will change nothing.

Their release - including their own rust code - is GPLv3 also - you seem to have ignored that.

Any idea why the CHIP temps report is not working? (i am using the latest version)
with the 2019 version have no problems...

Have been playing with OS+ tuning. Anybody know the most efficient setting for temperature and power. I can get close to 75w/th with 1050w setting at 75C target temperature. This is with my best hashboards. I find higher temps I start to lose efficiency, but I do like the lower sound around 80C or 85C target temp.
I find with the power setting of 900w or less, efficiency isn't that great.
I chose 900W in the configuration with default fan and temp settings and it auto tuned my S9i to 825W at 11.9TH. That's 69.3 W/THI find with the power setting of 900w or less, efficiency isn't that great.
Another S9i I chose 800W with default fan and temp settings and it auto tuned to 723W at 10.4TH. That's 69.5W/TH. It always ends
up with a watt reading lower than what you choose on the configuration page.

Are you trying with the latest release from yesterday? There is apparently a new setting to limit the lowest frequency to try, but by default it will try all the way down to 155 Mhz (and all the way up to 950Mhz).
Maybe this answers Kano's question:

CGminer, BOSminer, and GPL Compliance
There has also been some discussion recently amongst miners about GPL compliance when it comes to CGminer. We want to be clear about how this applies to Braiins OS.
Up until our latest major release (March 2020), Braiins OS was built on top of CGminer, which was using Bitmain’s FPGA code as a backend. This component from Bitmain was closed. We built BOSminer from scratch to replace CGminer in order to make everything open-source, including replacing the previously closed FPGA IP core with our own open core.
In other words, the above paragraph simply means that Braiins OS users do not need to worry about this GPL matter because we are not using CGminer or Bitmain’s FPGA IP core.
Additionally, it should be noted that we own the IP for BOSminer and we have a contributor license agreement in place for it. Braiins OS is released free of charge under the GNU GPLv3, while Braiins OS+ has its own software license agreement. We reserve the right to use this software however we see fit, including providing commercial licensing to individuals should they be interested. If any hardware manufacturers want to implement BOSminer, we will be happy to accept their commits to the public repository and keep this open standard for the mining community through the contributor license agreement.
We are focused on continuing to develop our products and supporting our users as best as we can. What others in the industry do in regards to this matter is up to them.

Their autotune algorithm is proprietary, i believe this is embedded in "BOSminer+" when you use Braiins OS+ rather than Braiins OS.
The rest shares the same code as far as i know. Feel free to check their github etc.
Braiins OS+ has a 2% devfee. If you use it with Slushpool, the pool fee is reduced by half (1%).
Stay tuned for the imminent next release, things are only just getting started...

The rust code in the github is GPLv3 so they can't include that in a closed source release if they change even a single line of it.

Hello, Braiins OS works on T9+?
Thnx!
Thnx!
The only currently supported models are: S9, S9j and S9i. Nothing else.
The next release will likely add support to the S17 family. Other models might come later, so stay tuned.

just seems that it is a tiny bit hypocritical to say the funding from the dev fee is to further the open source nature of the whole thing when its not fully open sourced.
but that is my opinion.

why is braiins os+ not open source like the original braiins os?
it was probably mentioned somewhere but I missed it if it was. Also, doesn't the site state
Revenue from Braiins OS+ is used to continue developing the open-source mining stack sustainably in the years ahead
if its to "continue developing the open-source" - then why is it not itself open source?
or am I missing something here?

So been a week with bos+ and here is my experience .
I put 4 miners on it . S9i , S9 and S9J
autotune works great , it's stable once it's set .
Problem i notice is the autotune is not saved so if the miner needs reboot u have to run the autotune again .
Also on those 4 miners 3 of them simply stopped mining at some point for no reason and a reboot was needed which is annoying cause i had to run autotune again .
Some miners would not show the chip temperature on bos+ but on the old bos or bitmain ( cgminer) it would show up .
Can't go spreading bos+ on a lot of miners cause i'd get issues daily and have to run autotune all the time at a 2% fee.
Will wait for the next update and test again, hopefully they fix those inconvenient bugs .

Take a look at the logs, when its autotuning, it shows the word TUNE (Cheesy Tune)
. It may restart many times while trying different speed and voltage combinations until it decides it has the best one.And yes we have requested better signaling for this, maybe some alert in the UI and i personally requested a led indication, lets hope they make it soon
It seems they are focusing in bug fixing, improving (and saving) the results of autotuning, and add S17 support.
Be careful fiddling with the powerlimit value, i think this value is based on estimation, I don't think the controller can tell how many watts the PSU is really pulling. A tool for measuring is the safest bet, don't pop your PSU! The default is 1420W which should be safe.

Also, both editions use BOSminer rather than cgminer, which allows Stratum V2 for secure connections to any pool that supports it.
If you decide to use Braiins OS+ with Slushpool, the pool fee is half, so instead of a 2% pool fee you now pay a 1% pool fee.
Since Slushpool looks for BOSminer ID flags then that will certainly make it very easy for Slush to know if their software works as-advertised and finds blocks. When a miner finds a block Slush and the BOS devs will know what it is running.Also, both editions use BOSminer rather than cgminer, which allows Stratum V2 for secure connections to any pool that supports it.

Does this mean that they might finally answer this simple but seemingly intractable question: "Does it find blocks at same rate as 'official' OEM firmware" by providing direct proof that it does?

Doesn't that mean a 3% pool fee? i.e. it went up?
1% pool fee + 2% dev fee (to the pool) required to use OS+ ....
P.S. paying 2% of all your rewards for a basically pointless SSL slower connection to the pool seems expensive ...

One of the reasons I don't have more units mining on this firmware is the no proof issue of blocks.
I have about 2 ph of sha-256 mining on viabtc pps+ it would be nice to see some blocks hit proof for any aftermarket firmware.

YOU are in a better position with your mining hoard to test this simple but (seemingly) enigmatic question. A single miner will undoubtedly have almost ZERO chance to find any block with BTC, but 2PH could easily solve the problem of answering this question mate.
...
You don't need 2PH to test it.
It's a simple question that the developers can test and answer.
Test their code properly to ensure it does find current level blocks.
No idea why they won't do this unless it's beyond their abilities?
If that's the case then everyone should be concerned about using software they wrote ...
... though ck wouldn't do it either on his pool code (and lost blocks ...) even though I also told him how to test it properly

I'm testing the autotuning on 3 S9's
One superstar s9I that was giving me 14th @ 77j/th with regular BOS.
One S9 that was problematic , had horrible stability and efficiency with other custom firmware and bitmain. Talking about +95j/th.
One S9J that always stopped mining after 1 min on bitmain and BOS.
On the webpage i read somewhere that it takes between 2-6 hours to autotune , how do i know when it's done ? there's no indication it's tuning except for the fact it changes frequency and voltage every now and then .
Short of testing it myself on every miner , how do i know it's actually running at the watt i set ?

the new firmware bos with autotune has a 2% dev fee ?
Braiins OS in the year 2020 offers two versions:
Braiins OS Community edition: No fees, no autotune.
Braiins OS+ Enterprise edition: 2% devfee with autotune.
The autotuning component remains closed proprietary, but the rest shares the same open source code.
Also, both editions use BOSminer rather than cgminer, which allows Stratum V2 for secure connections to any pool that supports it.
