Bitcoin Forum

I'm making this new thread to focus in support issues and not get derailed with off topic things anymore.

Remember that this is by my own initiative, official support is provided by opening a Support ticket (https://help.braiins.com/en/support/tickets/new), or in the Telegram Group (http://).
Official web page is here: https://braiins.com/os/plus

I will try to keep this first post updated with latest releases and supported hardware.

• [improvement] Improved Power Curves for S19j PRO and S19 PRO
• [improvement] Adjusted power limit defaults for Antminer X17 family

NOTE: The default power limits for the X17 family are now aligned with the stock power limits based on the machine variant. The previous default power limit of 1700W is now 2200W, which will more closely match the consumption and hashrate output to the stock specifications.
IMPORTANT: If you are currently running many X17 devices at the default power limit, this update will cause a significant increase in power consumption. To prevent that, you can simply change the power limit on your machines slightly (e.g. to 1710W) so that the upgrade does not cause any major changes.
If you install Braiins OS+ on a stock device, or have been using a user defined power limit, this change will not impact you at all.

---

22.06 This is a major release for Beaglebone control boards only.

• [feature] Added support for Beagle Bone based control boards (including tuner, but excluding the auto-upgrade functionality)

Note: this release won't run on other than Beaglebone control board equipped miners.
Note: not sure which control board you have? check here (https://braiins.com/blog/bitcoin-mining-control-board-variations)

---

22.05 This is a minor release containing improved power curves for selected Antminers models.

• [feature] Power curve matrix has been added for models S19J and S19 pro so the estimation of power consumption is now more accurate

Braiins OS+ is a full replacement firmware made from scratch. Braiins has to figure out hardware support without any aid or documentation from manufacturers, for this reason the number of supported ASIC miners is limited. Braiins takes no shortcuts like others that illegally mod existing firmware and infringe cgminer's intellectual property (https://github.com/ckolivas/cgminer/blob/master/COPYING) (see Section 8), therefore its impossible to support new miners that have been just released. It takes countless hours of research and development to support each new variant or model in a manner that is clean, safe and efficient.

Braiins OS+ is made in Czechia part of the European Union with the highest standards of excellency.

Unlike others who don't care about burning your miners, Braiins cares. Only Braiins OS+ prefers to stop using what it doesn't like, others are "do it no matter what" mindset. Long time farm operations save with extended hardware longevity and unrivaled uptime because of this, which is what makes profitable what others lose in downtime and repairs. Also your company won't be liable for the use of pirate software that funnels money to an OFAC sanctioned country. Braiins OS+ is CLEAN, nothing from the manufacturer, nothing from cgminer, designed from the bottom up, not patched with a gazillion holes, mem leaks or a reckless uncaring and ridiculing attitude. Those incapable of writing their own mining software are no competitors, but pirates.

Braiins as a company exists since 2011 (https://braiins.com/story), 13 years of unparalleled experience; and it shows, the industry knows the truth.

Since Braiins OS+ release in 2020, the results have always been the best efficiency, often resulting in a "generation leap". For example:
People who use it with the S9, can make 74 J/TH, same as S11 with stock.
People who use it with the S17, can make 29 J/TH same as S19 with stock.
People who use it with the S19j, could make 21 J/TH same as S19 XP with stock.
People who use it with the S19 XP, can make 18 J/TH same as S21 with stock.
People who use it with the S21, can make 15 J/TH same as S21 Pro with stock.

Clean, safe, efficient. Braiins OS.

For most of 2023, you could have made your XPs achieve the so called 1XJ/T ahead of the manufacturers newest models, by simply using Braiins OS+.

Even if you subtract the dev fee, you still get better than others with "zero fee". For example 101.2*0.975=98.67 1856.3W/98.67TH=18.81J/T (normalized against "zero" fee). By using Braiins OS+, you support the development of a truly independent and clean alternative developed from scratch.

The reason why Braiins always achieves the best efficiency is because of its unique autotuning, a deep and continuous process others aren't able to imitate no matter what they claim, since they don't get it and take shortcuts which are inefficient and never adapt truly to your hardware. Its not who does it first, its who does it best. Worldwide market adoption has been overwhelming, and for good reason. Think of cars, what quality you get from Europe, America, China and Russia...

And on top of that, enjoy the 0% pool fee by using Braiins Pool. Since you are already paying for Braiins OS+ you get the benefit of using Braiins Pool for free! Two products for the price of one!

I have a question will you consider doing bitmain L7?

Also I was considering getting some 'better' psu's

---

this says it will work with your software
s17 after market psu

the 2 below do not say they work with your software
s19 after market

https://parts.kaboomracks.com/collections/power-supplies/products/alpha-miner-psu-4kbm19-apw12-new


s19 modded

https://parts.kaboomracks.com/collections/power-supplies/products/bitmain-apw12-psu-modified-from-used

they are supposed to be better made but will they work with your software?

The only aftermarket psu i know that works right now with Braiins OS, is the Gullpower, specifically the GPW121215-8KW immersion PSU. Some crazy person managed to pull "Over 9000!"™ watts at the wall with it... So the thing does deliver.

The development team is also studying the Alphaminers, but for some reason those need extra firmware support, so i don't know when they will get supported. Last time i read they were making the 7kw model work, so i think it should get support sooner or later.

I suppose the model you linked was tested by the reseller so they would know, when i get confirmation from a third party I'll add it to the list.

Other aftermarket brands/models are unknown if they would work or not. The Gullpower was discovered by adventurous people who just tried.

Its the same way others also discovered the Zynq control boards C87 and C84 "just work", unlike that Beaglebone and Amlogic trash which imo are a waste of dev time and resources (they should be just thrown out), even if its theoretically possible to make them work, they do suck, very low capacity, poor cpu, etc. For example with the BB tuning takes much longer as it can't do all hashboards in parallel. Even Bitmain won't ship them if you break your board and ask for a new one you will get the C87 which is perfectly fine like the other Zynq.

Braiins is fully committed to Bitcoin, so the other algo asics will not be supported. Its also the reason altcoins were finally removed from the pool.

Fair enough about the L7

I will likely order some of those psu's from kaboomracks in the next few months. As I get tired of the s17 psu's burning out.

Wouldn't finding a drop-in replacement PSU mainly be a matter of knowing the specs for it? Namely:
Output voltage range
Output current
Max power out rating
And here's the most important bit -- how the controller talks to the PSU to set the voltage output fed to the hash boards and if/how the controller knows what the PSU is doing. Is it simple 0-5v analog coming from a DA converter or analog output port on the SoC? Serial coms like I2C? PWM signal? etc.

Unfortunately no. Bitmain played dirty tricks again.

In regards to the "J" miners, there are two different ones: Old ones, with pic in the hashboard, New ones without it.

You can only recognize the "New" ones when they come from factory with the PSU APW121215 rev D or later. You cannot use older PSU revisions with these "New" miners as it lacks the detailed power control. Old miners should probably work fine with the New PSUs though.

You cannot recognize the "New" hashboards without removing heatsinks, so be very careful with mix matching PSUs. Once Braiins OS supports the New miners, the log will alert if the old rev PSU is connected to new miners.

The APW121417 also uses these pic less hashboards.

I suppose the aftermarket PSUs will all just have to adapt for the "New" miners, but who knows.

Yeah, gone are the days where the PSU only supplies 12V... It changes dynamically within a range. Well the control board itself is still getting 12V (and feeds the fans with that).

Actually Frodocooper complained about these bespoke psu's back in 2018 when the s15's came out.

it is a pain in the butt if you have cheap power and a slightly older psu dies no one sells them and your gear is no longer any good.

I have 0 apw8's spares
I am down to 1 apw9 spare
I have 0  apw12 spares

So keeping older gear working just gets harder.

And as I said back then: There are 2 reasons for it.

1. Using more PCIe connectors to feed a multi-kw mineris a bad idea. Too bulky and already proving needlessly unreliable because of the connectors being pushed to their limit and adding insult to injury them often being plugged/unplugged many times over the life of a miner and or PSU. PCIe connectors have a very small number of mating cycles before they begin seriously degrading.

2. Wall plug power efficiency. Today's best Platinum 12vdc PSU's are what - 95% maybe 98% efficient? Now that 12v was being dropped down via a final regulator on each hash board to whatever Vcore is being used. Typical string voltage was what, 7.5 to maybe 9vdc? At best the on-board regulators were *maybe* 85% efficient so...

End result is that by losing the 2nd stage Vcore regulator losses using integrated PSU's that directly set the voltage results in more TH/kW plus by using bus bars it eliminates the high current connection problems. Oh, being able to use a higher string voltage lets ya use longer strings of chips so more TH/Current drawn through the string.

The main tradeoff is that the PSU is setting the Vcore string voltage for ALL of the boards. Um, since we all know that the ideal voltage for any single board can vary a fair bit, that means the tuning process ends up with the best *compromise* voltage to reliably run the weakest board even though the other boards may perform better with a different voltage.

Now as to *why* BM,  Canaan, et al can't seem to have a more reliable PSU built is a mystery to me. It ain't rocket science to design a multi-kw PSU...

Looking at the APW8 schematics posted at https://www.zeusbtc.com/manuals/Antminer-APW8-Power-Supply-Repair-Guide.asp it looks like they use I2C to talk to the PIC in the PSU. Yes the PSU also seems to have two distinct ranges for the DC output: They describe it as 15.9-16.3v and then give an upper range of 19.92-20.5v. Point is, assuming it *does* use I2C and you know what format the commands are sent to it are, it should be easy for some 3rd party to make a compatible PSU. Just have your firmware be able to identify what the hash boards are & need for voltage and talk to the PSU...

It's because they are cheap, they try to reduce the cost at the expense of other things, I think they set a fixed price for the cost and ask their engineers to design something within that price, all these asic miners manufacturers companies do some stupid shit that nothing justifies it except being cheap.

MicroBT do make some solid PSUs and they have a very low failure rate unlike Bitmain and Canaan, but for some reason (probably cost again) they suddenly switched from using 6 flat pins to 4 square pins, so if have a miner that has the flat pin connector when you change the PSU you are going to have to buy a new set of fans and those fans are not cheap, by doing this, they make keeping spare parts a harder job, now you need to have spare fans for both PSU types that are used by the same miner model.

So long as it does not die within warranty they don't care. It's not a lot different then how a lot of things are built today.
Get it to X price and design it to work for Y amount to time with Z reliability. It's not like there is a lot of competition in the space. A few vendors, and although some are better then others there are none that are Toyota HyLux reliable.

-Dave

and besides that, they probably know that most people won't send a whole unit just to get a PSU repair, which is what is happening, many PSUs fail within the warranty timeframe and they don't get any repair tickets for that, because it's almost always cheaper and more reasonable to just buy a spare PSU locally than having to send the miner in for a few weeks/months and still have to pay shipment fees and all, so they know they can easily get away with PSUs that die in no time.


lol, I can vouch, my grandfather had a 1988 hilux  , it was a tank, when we were young my cousins and I would spend the summer in the farm, he would wake us up at 5-6 am to walk the sheep and we would come back at noon, he would take a nap and we would steal the car keys and drive it (actually abuse it) around the farm, we did some unintentional off-roading with it and we didn't even know how to probably shift the gear, honestly, we were barely tall enough to see what was in front unless it was a large tree :D, my Jeep now can hardly do half of that before needing a major repair.

Just Wondering ...

If I managed to get decent PSU produced, would there be a market for them to cater for the PSU BreakDowns. If anyone is like Me, Discarding the PSU and Replacing with a new one seems to be a far better way of doing things than pulling machines apart, sending a single component, waiting (IF they repair them) and having the machines offline for weeks sometimes (Being in Australia is a Pain in this case) and losing out on Hashing.

If there is a need for it, I would have no issues getting them produced and stocking them for such cases, and for the Communities to at least have an option to go elsewhere (to Us at CWI as an option) to source PSU units at a reasonable Price and actually being stocked with them - as long as demand is not too great of course.

I would be happy to supply a few for testing if that is the case.

Just an idea, and I hope I am not pushing an issue here. I know how We are with our machines and it is usually the PSU not the ASIC that dies WAY before anything else does. We have replaced hundreds of them in the last 12Months, which is why I started sourcing 'decent' ones for our Farms.

As for the OS - where would one go to request features for the FirmWare?

Hi, what is the command via SSH to 'Restart BOSminer'?

/etc/init.d/bosminer restart

or with bbb:

/etc/init.d/S99bosminer stop
/etc/init.d/S99bosminer start

great, worked. thank you!

other question, I wanted to change fan speed — from 100% to 50% — while restarting BOSminer with the following command:


but terminal says:


what am I doing wrong ???

Bitmain Antminer S9 with Version: 2022-06-20-0-288861e4-22.05-plus

Is there a way to stop the fans (Antminer S9) from going to 100% at startup. I use Braiins OS+ and have the noise level very low because I use only 600W. Since I need to restart the miner quite a few times depending on availability of power, this would be very helpful.

so I am looking to do a s19 pro 110th with this hashboard


https://vmssecuritycloud.com/product/new-authentic-bitmain-oem-s19-pro-s19-t19-control-board/


it does not have bugle bone it is xlynx

so what is my firmware link to run this and load an sd card

I did an 8db sd card with the x17+x19 firmware and it only mentions s17 and will not allow for programing .

so do I load it with the one that say bugle bone.

to be a person that does have some interest in running a lot of s19 pros

it would be easier if the file just read s19pro rathe than seem to be able to do both s17 and s19.

so for now no s19s are using braiins

has anyone tried a c87 in a new s19 xp to get braiins os+ working on it?

That old trick for the fans no longer works, the script was changed, besides it can't prevent fans going 100% after power is cycled anyway. You could just switch to silent fans from the likes of Phantek or Noctua, make sure the S9 is configured for low power limit.

---

S19 Pro 110T works perfectly fine.
Why would you care what the file is called? Its the same file for both families, of course it works. Beaglebone is for beaglebone only.

If you plug the C52 or C49 you can even use it from NAND. If you have the others, you must use it from SD. Others meaning: C87, C84, C71, C55 they all work fine from SD only.

I don't like BeagleBones, they work (from SD) but the OS is more crippled, for example autotuning takes longer due to its low spec cpu.

S19 XP will be supported in a future release, it doesn't work yet, and its not a mere control board issue.

S9 w Braiins OS+ - haven't been able to connect to Zergpool. I think I'm missing some bit of syntax in the pool info. I am currently running a gekko setup with CGminer, an Apollo, and a couple of CPU's with XMRig - all on zergpool successfully. S9 is currently on another pool and I've mined on CK solo with it before.
I've tried everything I can think of to move the S9/Braiins+ to zergpool and it always comes up Pool Dead. I think I'm just missing something with the syntax.
Has anyone else experienced this? Interested in assisting my troubleshooting?
currently Pool URL: stratum+tcp://sha256.mine.zergpool.com:3333
username: bc1...(wallet addess)....zw3gs
Password: c=BTC, ID=ShaRightS9

It seems like it times out too quickly? Just gives up trying to connect after a couple of seconds.

You can't put that space in the password.

In other news, as demonstrated in the past, Braiins OS+ has reached the efficiency of the next generation:

First the S9 reached the S11 (74 J/TH ARGFA).
Then the S17 reached the S19 (29 J/TH Bas Laurier).
Now the S19 reaches the XP (20 J/TH Sadnudbi).
* These were all shared by users in our Telegram support group.

https://i.imgur.com/Kbe0VBI.png (https://i.imgur.com/Kbe0VBI.png)

It was set to Power Target 1616, HOT temp changed to 60C and Dangerous to 70C with dynamic scaling enabled with a step of 200W.

Theoretically with two of these you can surpass the XP:

Single XP 127T 2730W
Two jPros: 128.6T 2686W

Efficiency matters. Profile shortcuts provided by crude mods that pretend to "invent" autotune will never cut it.

I've tried it with the space removed, still the same results. ( c=BTC,ID=ShaRightS9 )

Well i don't know about zergpool but zpool and mining-dutch did work in the past. Maybe there is a different port for sha-256 asicboost so check your pool documentation.

Be mindful that the latest firmware upgrade promised by the manufacturer for Christmas (https://twitter.com/BITMAINtech/status/1602665283768188929) may actually render the machine unable to run Braiins OS+.

Its best to not upgrade and wait.

hey all. im going to ask this here as well. i have sent out a support ticket to braiins as well. just trying to figure out whats going on and how to fix it.

i just purchased 2 antminer s9's back in april 2022. i set them up using the braiins os+ software and of course i mine on there pool as well.

so everything was running just fine and all. but then i shut down my machines manually on christmas morning since my machines are in my living room. lol
after we did presents and all i turned the machines back on. everything was fine and all until i looked at my braiins app on my phone on dec 26th just after midnght.

thats when i noticed my machines were not working properly. they were mining on some other pool for someone else.
this is something very new to me. no 1 else in my house knows my passwords for anything.
so somehow someone "hacked" into my antminers and changed the pool config.

i have deleted there pool and put mine back in. and i thought all was well again. but after only 1.5 hrs on the dashboard page it showed a new pool address and username
but on the config tab there was nothing but my pool information.

i contacted support at braiins and im waiting to hear more from them.
they said i was running an older version of the software so when i got home from work i tried to install a newer version onto the machines but each time is says i am already running the current version.

of course i would really like to keep mining but currently im running my machines so they can work for someone else. lol

anyone have any ideas on how i can fix this problem so i dont have to shut my machines down.

thanks for any and all help.

Had the same issue with mmpool and Braiins OS (with a Antminer R4, flashed with S9's firmware) some time ago

I don't find it again but I think I saw Kano explaining on the forum that some pool refuses braiins os (maybe because of the modified cgminer or i don't know ?)

There is no such a thing. We do not use cgminer. it was removed in 2019 and replaced with bosminer in 2020 made from scratch. The pool must support rolling version which is generally added with asicboost or it will not work. I have personally tested with some yiimp like zpool and mining dutch, if there is an issue with mmpool then they must investigate it. In general Braiins OS has been tested with most Bitcoin pools and if other coins work, fine if not, change pool. Altcoins are not officially supported.

The previous poster seems to be in a compromised network, with some malware or worse. This goes beyond Braiins OS+ support. What good is changing the password if they have a malware in a windows pc sending all keystrokes and desktop screenshots to some malicious entity? The most common mistake is not setting a password in the miner, but that is not the only security issue. The less computer savvy people are, the more prone they are for these exploits.

Hi!

I have some antminer S17 PRO, T17, T17+ that I would like to install Braiins on. Now stock firmware.

I want to flash two sd card with Braiins, one for installing braiins to the miner. The other one using Braiins only as long the sd card is in the slot.

Thinking to flash with software Balenaetcher.

What files should I use for each sd card. There are three files to download.

beaglebone-x19_SD_runfromSD.....zip

x17_SD_autoNANDinstall....zip

x17+19_SD_runFromSD....zip


What file should I use together with BOS+ toolbox?


Perhaps it's a stupid question but had trouble installing and uninstalling Braiins, that's why I'm asking these questions.


Thanks in advance!

Ok i did some small editing in the first post to make things easier for you. There is an issue with the install to NAND option, so you need to use a slightly older version to do it, this is now reflected in the link for S9 and x17.

The toolbox needs no files, it downloads what it needs on its own. You can only use it to install to S9, anything else needs physically inserting the micro SD card and leave it there if you don't want or can't install to nand (x19 control boards).

If you stick to always using micro SD cards, there is zero complication to "uninstall", just take it out of the miner. There is no need to install to NAND ever.

You mean an older version of Braiins, if so were to get it?

You are right, but prefer to install to nand believe it or not.

After starting up with the sim card, I go to System -> Install current system to device (NAND)

Here I get the error message: found argument "config" which wasn`t expected, or isn`t valid in this context.

.........

Failed to parse message data

upgrade stage1 failed

process return code was 1


With an older version of Braiins it will be possible?

In the first post of this thread.

Feature request:

Add a flag / parameter to inhibit Auto Tune, thus using / keeping the current tuning results.

Why: The rig had been running fine. Suddenly, reason, unknown, auto-tune kicks in for one or more cards and it spends the next 12 hours doing it's thing. Sometimes the results are even worse than before. So 12 hours are hashed at 1/2 the normal rate while tuning.

If I can catch it, I will reload a saved configuration. That takes jut a few minutes to get back to the normal hash rate. If not (or don't have a saved config.), and the results are worse, I will then have to set the  power rate at a watt or two higher than before to get auto-tune to kick in (or edit the auto-tune file), but that's even worse as now the whole rig is tuned.

The software saves the best frequency for each chip at a certain card voltage in a unique json section for each card, for each power level. I'd suggest using that data when starting a tune, vs blindly cyclying thru all the combinations.

Oh, and make auto-tune enable & power level selectible each card. I may want to set a given voltage / freq. for a particular card while other cards auto-tune at each specific power level.

Reason is not unknown, chip performance degraded (see log). This is a design feature and is what makes Braiins OS+ so different to others who don't care what happens to the miner afterwards.

If you run it with manual settings, you are on your own. We don't do presets, no shortcuts, and no tune and forget.

If you don't like it, try to investigate the cause. Make sure chip temperature remains constant and your power is stable. If it happened its because its needed, its not done on a whim.

The last thing only made sense for the S9, now the voltage is shared and there is nothing you can do about it.

I don't know if you understand it, but to reach peak efficiency you just can't take shortcuts, its not setting a bunch of speeds and voltage like an old fashioned overclocker. There is a very complicated way to reach that state, which cannot be shortened without losing efficiency. Yet again the reason we can do what others can't.

Sure you can have some sort of preset that is "good enough" for a group of machines, but it will never be the glove fit that is Braiins OS+. And the results are out there...

Is there any way to stop the miner from going 100% on all fans during start up? Limiting it to like 30-50 would drastically improve home mining conditions.

It is not possible. When you power up a fan it goes to 100% before the fw loads or does anything. Consider a hardware controller or replacing the fans. For example the 3k RPM Phantek or "industrial" Noctua; or an external inline fan used for ducts with 3d printed adapter.

Try with something like this - https://www.amazon.co.uk/Control-Module-Cooling-Potentiometer-Chassis/dp/B0B6Q2NGSG

What people also build is a device that disconnects the fan for a few seconds via a relay. It switches to a dummy fan adaptor for some seconds after start and then switches back to the fan, when the miner is up and running. Sadly this is not commercially available as far as I know.

Here you can find some more tips: https://bitcointalk.org/index.php?topic=5436532.msg61644308#msg61644308

Hmm you can do that without the dummy with Braiins OS. Just enable immersion mode.

Also remember to edit your first post, miner doesn't stop hashing at Hot, it does at Dangerous.

I got BraiinsOS+ going on an S9J miner, running from SD card.

Installation was very easy and it runs without the stock fans connected. That's nice because I have an external large fan to suck air through the miner.
However, I wonder why there is no warning, because the temperature control mode is still set to 'Automatic'.

I'm wondering how to set the correct values for temperatures. Looking at this page https://support.bitmain.com/hc/en-us/articles/360020079754-S9j-Specifications ,
what does 'Chip temperature: 95C' mean?   Is that a maximum to avoid or a target to achieve? When I was running the miner with it's stock fans, the chip temperatures remained in the 62-65C range, but that was in low power mode.

And in general for the BraiinsOS+ configuration page: Is 'Target temperature' meant to be reached (for efficiency or whatever) from above or from below that temperature?

The default values are correct. Bitmain changed the way S9 reports temperatures around 2017, basically subtracting 15°. The oldest firmware reports temperatures exactly the same as Braiins OS: as the sensors send it.

What warning? If it reaches hot fans go 100%, if it reaches Dangerous hashing stops. You can change them if you wish.

In the Bitmain specs the max chip temp is written as 135°C. Someone mentioned that factory fw stops hashing at 130°C. Braiins OS is far more conservative by default.

The default requires 1 fan plugged, if won't hash until you enable "Immersion mode" which means minimum fans required: 0, and nothing else.

Thanks for the explanations!

Very interesting to watch the auto-tuning in progress. Takes quite a while!

I notice particularly that one of the 2 connected hashboards (1 of the 3 is cactus and not connected) always had a higher chip temperature than the other one, but after about 8hrs of tuning the chip temperatures are now even.

After tuning is complete, I'm getting 11.2TH/s, that would be 11.2TH/s / 2 ×3 = 16.8TH/s from a 14.5TH/s spec miner. A 15.8% increase.

Estimated efficiency as per BraiinsOS+ is 96W/THs, and the measured efficiency at the wall (including PSU and 8'' Phresh fan and ethernet hub thingamabob) is 1062W/11.2THs = 94.8J/THs.

Regarding the 'missing warning', I meant this: I powered up the (2/3rd) S9J without it's stock fans, with the brand new BrainsOS+ SD card and cooled by a Phresh 8'' ducted fan (with manual control dial to adjust the speed). BraiinsOS+ had no way of knowing that a big manually controlled fan was taking care of cooling, and the 'Enable Immersion Mode' was not ticked, but it did not warn something might be wrong. It did however show Fan Monitor 0% 0% 0% 0%
I have since ticked the 'Enable Immersion Cooling' box and now the non-existent fans are shown in Fan Monitor as '100% 100% 100% 100%'.

Questions:
1) Does it matter if I manually adjust the fan speed during the tuning process, or if the air intake temperature fluctuates? It seemed that setting the 'Enable Dynamic Power Scaling' caused trouble. Because I did not realise that cooling requirements do fluctuate so much during tuning, and because I was trying to keep the noise low, the power reduction got triggered a few times by reaching the 'Hot 100C' temperature. Then I turned 'Dynamic Power Scaling' off and tuning appeared to progress more orderly.

2) Can the results of the auto-tuning be stored and then implemented quickly after a restart, or must it go through the whole tuning process every time? I ask because I plan to run comparatively inefficient miners like this one on 'free/stranded' electricity from solar panels. The miners will need to turn on and off frequently, or maybe ramp up and down their power use depending on SOC of solar battery, strength of solar irradiation and grid feed-in tarrifs, or when max allowed feed-in power is reached.

3) Will it make a difference to the tuning results (or to the tuning time requirements) what 'PSU Power Limit (for all hashboards)' I set? I am using a HELA 2050 Platinum PSU (up to 2KW) and I noticed that the auto-tuning starts at different power levels and frequencies when I set different PSU Power Limits.

4) What is the best / fastest / most efficient way to find the most efficient J/THs setting?

5) What is the best way to find the lowest possible power setting for a miner?

Rebooting the S9J with SD card with BraiinsOS+ in it has answered this question. Very neat!

https://i.ibb.co/CPY4z1m/Stable-Screenshot-from-2023-03-05-14-46-21.png (https://imgbb.com/)

0) Like i said, it won't hash. It leaves the red led on, and the log shows the error "0 < 1 fans... blah blah" What more warnings you need?
1) For S9 it doesn't matter much, The S19 chips are much more sensitive to temperature fluctuations. DPS is optional but you should keep the target temperature (or less) at all times. Of course it should trigger if you fail to keep the miner cool, that's its purpose. The S9 family does not scale back up on its own even if temperature improves, it needs a bosminer restart (can be scheduled).
2) Its saved and reused as long as chips perform properly, chip performance is monitored 24/7. Sometimes a power fluctuation will make them misbehave and a full autotuning process may be invoked again.
3) Of course, that's the whole point of setting the power target. Each hashboard gets 1/3 of this value.
4) The autotuning will find it according to the power target specified. Each miner is unique and will give slightly different results.
5) Best user shared result was at 825W (set to 900) 60°C chip temp. Next best 1142W (set to 1150) 89°C. S9j 14.5 and S9i 14 gives the best results.

With S17 i have seen results as low as 29 J/T, S19 pro 25 J/T and S19j pro as low as 20 J/T (measured at the wall).
Note: S9 = 16nm, S17, S19 Pro 7nm, S19j Pro 5nm.

Rough average is 20% efficiency increase (meaning, use 20% less power at factory hashrates), usually more efficiency with lower power targets but it depends in the specific miner itself and chip temperature. No two hash boards have identical chips and only Braiins OS+ can find the most efficient result which is why its autotuning process is so involved unlike other wannabe imitations that not only use shortcuts that are suboptimal for the specific miner, they just "tune" and forget; without any care if the miner breaks later...

That's the issue: I did hash (on first run, no fans connected except the big one that BraiinsOS+ does not 'know' about). I will try this again with a new / repurposed SD card at some stage. Please let me know how exactly you would like me to test it if you think it depends on something or another. It looks like BraiinsOS+ was/is ignoring that 'Enable Immersion Mode' is not selected on first run.

I would like to 'build a library' of settings'. What is the best way to do that?

BraiinsOS+ is very good at optimising hashrate, but I would like to be able to turn on different optimised setting quickly.

For example:

"Minimum noise' cause I'll be sitting next to the miner for some hours today".
"Maximum Hashrate, I have free electricity toady".
"Maximum Efficiency"

Questions:
My assumption is at this stage that BraiinsOS+ will only remember the most recent completed tuning result, is that correct?
Would it be the easiest method to etch a number of SD cards and then run the auto tuning process for the desired (and previously tested) setting on each SD card? Then label the cards and put in the one I want?
Do I remember correctly that the SD card must be 16GB?

Hi,

I'm thinking about getting hold of a miner supported by Braiins OS+ and use it to mine bitcoin using solar excess power. Summer is coming to the north hemisphere 🌞

From what I can gather in docs.braiins.com, I can edit /etc/bosminer.toml and set psu_power_limit to limit the amount of power that the miner will use. IIUC, this allows me to say "ok, I have 3000 watts available and am using 1500 at home, so I can divert 1500 to the miner", then set "psu_power_limit = 1500" and maybe restart something.

Is the above correct?

If it is, what's the minimum step that psu_power_limit accepts? Can I set it to eg. 258 watts? Or do I need to jump from 100 to 150? Or jump from 100 to 200?

The default configuration is minimum required fans 1, as long as you have 1 fan or spoofer plugged, it will hash unless it overheats and stops due to reaching Dangerous temperature.

It will save all the profiles. So you can tune it for low power, and when stable, switch back to the default quickly, and to the low power quickly.

No, because every miner is slightly different, main reason autotune by Braiins OS+ is unique while others take shortcuts which are not as efficient or adapt to your real chip situation in real time 24/7.

16g is what the manufacturer says. I presume it may work with 32gb as long as its sdhc and NOT sdxc, but smaller sizes are safer.

---

womanderful: Yes that's the general idea, and the steps are 1 watt. But you should double check by measuring at the wall, since its only an estimation, and in the case of the x19 family, higher chip temperature will make it use more power while producing the same hashrate. Min and max values depend on miner model / submodel / variant. You can also just disable one or two hashboards (each hashboard gets 1/3 if this value). Or you could just pause the mining completely and resume hashing later.

Support has vastly increased compared to previous versions, at least using the bbb or Zynq control boards, almost all x19 should work now, except the jpro+ because that's too recent, or the S19i and S19+ from being too rare.

But mine did hash without any fan or spoofer attached. Anyway, I'll test that again one day when I have a suitable SD card and spare time.

The saving of all profiles is great, the software works really well!

My beat up old S9J with 2 hashboards and a 2050W new PSU and 200mm Phresh fan gets to a peak efficiency of 73-74J/Th when set to 900W (measured at the wall including PSU, fan and WiFi extender). I have not tried it in 50W steps yet, but both 800W and 1000W settings use more J/TH than 900W, so it's close to ideal.

It is also very quiet at that 900W setting, the Phresh fan needs to run at only 25% (rough estimate) to keep the chips at 85C in 29C air temperature.

Why is it that the power setting does not get reached? When I set 1000W, it settles at 683/1000W etc. Always a bit more than 2/3rd of what I set in the 'PSU Power Limit (for all hashboards)'.
Is it because I have only 2 hashboards connected? The "Override Global Hash Chain Configuration' is set to enable only Hashboard #6 and #7.

Edit: Another question: Is support for any Innosilicon miners coming in BOS+?

It is because the hashboards each get 1/3 of the value. So 900/3*2=600.
Innosilicon not at this point.

What does it mean on the BraiinsOS+ page under "Choose Miner" where it lists "Antminer X19" ?

Do you mean it includes all S19 and T19 models?

Yes.

what control board works with the xp? thinking about swapping my amlogic...

The current public release has micro sd images for Zynq and BeagleBone. They run directly from the sd card, nothing is ever written to the nand or eeprom. Insert the card and it runs Braiins OS, remove the card and it boots factory firmware.

Is there a thread or page where BraiinsOS+ tuning results are collected?

I'm wondering what results to expect, just roughly, for certain miners, to help decide which ones to buy.

Specifically, I would like to know:

- what is the lowest hashrate or power level that the miner was able to be tuned to?
- what is the best J/TH efficiency that has been achieved?
- what is the highest hashrate that has been achieved?

In case there is no such page, at the moment I'm interested specifically in results for an Antminer S19 90TH/s.

No, i collect them myself from people willing to share their results.

I am currently waiting for 23.02 results since the tuner and hardware support has vastly improved.

If you want to provide your own results, send me a dm with: Miner model, Real Hashrate, watts measured at the wall, chip temperature (Tuner Status: Stable)
I'm always sharing this file in our telegram group.

Your questions are basically answered this way: It depends on your own miner and conditions. We don't take shortcuts, pre-made profiles can only provide average results at best. True autotuning will find the best result within the target you specify for your own miner in your own place at any given time, and now without hashboard restarts or significant loss of hashrate during tuning.

Even better efficiency is observed using a lower power target and while having constant chip temperature of about 60°C or less.

If you read my previous messages in this thread, you can find out the best previous results. Miners with the highest factory rating tend to be more efficient.

For example I have an old result from a jpro 92T doing 22.1J at 74TH 40°C. Same miner did 29.5J at 110TH 69°C. Does it mean yours will do the same? Not necessarily, again it truly depends in your actual chips, the so called "silicon lottery" put in your hashboards by the manufacturer.

Only Braiins OS+ finds and achieves the very best your own miner can achieve, accept no imitations.

Thanks for your 'Yes' reply earlier!

However, I have another related question which may seem redundant, but I want to be certain a miner will run on BraiinsOS+ before buying it:

I am looking at an Antminer S19 with this sticker: " Ctrl_Board: Amlogic "

Is that control board going to be a problem?

EDIT: I think I found the answer: " does not have an SD card slot, only a microUSB " from https://braiins.com/blog/bitcoin-mining-control-board-variations

I suppose that still means no BraiinsOS+ for such a miner?

When shopping around for a miner, how best can I get a reliable answer from a potentially clueless vendor to figure out if the miner has a zynq or a BBB or a Amlogic control board?

And how could it be verified, eg is there an easy way to take a photo that shows a relevant part of the control board, so that even an uninformed vendor could show me a photo that answers if it is a BBB or a Amlogic board?

The external SD card slot is easy enough to verify the zinq variant.

C87 doesn’t work with my 141 xp

Wait for the next release, or try with a BeagleBone. The Zynq image is currently supporting a few less variants.

---

There is a new control board which is under study, it also comes with a microSD slot in the front, so no, it is not a safe method.
There will be an announcement about AmLogic, you should keep them. Only the aml has the usb port so its still easy to recognize from the outside. And only the bbb has no port at all, its also easy to recognize from the outside.

If it has a microSD slot, then hopefully it has a sticker with Zynq/Xilinx/7007 on top. Else you need to remove the metal cover and see for yourself.

Thanks again!

Regarding the new control board with SD card at the front which is not a Zynq board: How new is that board? Is a used miner that was initially bought in mid-2022 certainly a Zynq board miner if it has the SD slot at the front? Or when is the cutoff date?

Apparently from 2023 onwards, so in theory you should be safe. I actually got the first picture in late December. It is from CVITEK.

Yes, Bitmain is using cpus designed for real time video processing with AI acceleration for identification of people... A bit of a waste IMO.

My inner conspiracy-theorist is having a field day with that!  ;D

when you have rolling advertising for the same firmware and miners on 1 forum you start to wonder if bitcoin is actually worth anyones time. if braiins is needed bitcoin already has a problem. i already have credit cards who charge merchants 2-5% dont need a free p2p network currency firmware that charges 2% and a pool fee that charges 2% kinda sounds like the same ball of shit

You are free to run your own pool and develop your own firmware for free, lets see how far you can get...

Whats next, free lunch? You can hash things by hand if you don't want hw or fw optimized for said hw.

And in this forum anyone can run advertising signatures, got a problem with that? No we don't have a campaign running (I'm too lazy for it). If you don't like it, don't use it. If you don't like my messages, use the ignore function and go back to your credit cards.

Well ... I got pretty far actually ...

Though I guess your response will be that pool size is all that matters ... so everyone should leave your pool and go to the bigger ones? :)

I know, you are one of the good examples. But remember that even your pool is not 0% fee  :)

This was posted in reddit (https://www.reddit.com/r/BitcoinMining/comments/135srub/a_data_driven_overview_of_braiinsos_efficiency/):


I have been saying this for a good while: Efficiency matters.

You know what is not efficient? Pre-sets. Blind manual settings that may work "equally" with an average number of miners can only produce average results. Real autotuning has no shortcuts and only Braiins OS+ does it. Others can't bother to do the whole job, and they lack the capacity to do so anyway.

With proper autotuning, results vary with each miner, because each miner chip yield quality varies. The manufacturer just mixed many low yield with a few high yield chips so the average reaches their "advertised speed". Therefore the "same" (manual) settings will never be efficient across a vast number of miners and this just confirms what others in the industry have verified by themselves.

Furthermore, a blind pre-set doesn't monitor chips and doesn't self adjust in response, something Braiins OS+ does. Which is why, miners running Braiins OS+ last longer. The firmware protects the chips and acts while others just squeeze them until they die.

And yes the industry knows. Many just quietly test and adopt because the results don't lie, especially tests done properly like this one.

Braiins is not joking when it states it has pushed the mining industry, and more is coming...

I run with Bariin's software and have the following temp. settings for my antminer 17 series miners. In this case S17PRO, T17+ and S17+ miners.

Temp mode: auto

Target 75c
Hot 85c
Dangerous92c

Can't find any information from Bitmain about recommended chip temperatures for 17 serie only for PCB.

Does Braiins have any temp. recommendations or people in this thread?

You can delete those values, then Save & Apply, and it will restore defaults.

Okay, I will do that. To see what the defaults are.

On the stock antminer firmware, you can see the 4 temperature reading on the card. With Braiins I can only see the hottest. Why so?

Design choice. For the firmware to take action, only the hottest value is needed.

It will get better. Well hoping for it to get better.

This actually works? ...

I'm impressed!

#crysx #cwi

Still working . Since it is in my garage and not the farm I dropped clock to 2500 watts. I altered temp setting to 72 80 90.

It tuned over night and is now doing 97th and 2475 watts.

Saves me driving to repair guy in next state.

After much playing with gear I found the actual issue was the white info cable between the psu and the control board.

Since this firmware (brains+) will allow a solid under clock at 25 watts a th I will leave it in place for the next two months due to summer heat issues.

To have a second firmware is good for testing purposes as I would not have figured out what was wrong with this gear with only bitmain firmware.

By patient testing I got 2 s19 pros with 1 board running to two s19s with six boards running.

or 36th up to 210th.

First one I fixed by mixing and matching the six boards till three worked.
second one I used brains as the three boards left would not register with bitmain firmware.
they worked sporadically with brains+ so I then replaced the cable from psu to controller getting good results. Also I like this firmwares abiltity to go to 2475 watts vs 3200 watts.

I now see a tool box. but only for linux.

I will need to setup 2 pc's for this. or wait for windows/Mac.

I am getting ready to fill a box with s19's and s17's maybe 75 units if I use linux and your new tools program what is fee cost.

I likely will remain at viabtc not slush.  With luck I could be pushing 6ph-7ph soon.

A native mac and windows port is in the works but you can simply install WSL1 in windows and run it there, it even works with your windows web browser, run it without options inside wsl, and outside open http://127.0.0.1:8888

In MacOS you can use virtual machine emulation, with the likes of utm or multipass, install something like Linux Lite and run it there.

Of course Linux is better, it always is. I'm surprised you don't have a single Linux machine, when all your miners use it...

Here is a brief reminder of the difference of PPS vs Score measured over a decent amount of time:

https://pbs.twimg.com/media/FOoFx3aXMAwNK6c?format=jpg (https://pbs.twimg.com/media/FOoFx3aXMAwNK6c?format=jpg&name=large)
* Luxor should have been the same as the other PPS pools, it was a bug (fixed) because they are doing out of order shares and the firmware had to be changed to acomodate for this.

Fee cost has not changed. If you aren't doing curtailment, you earn less satoshis using those Chinese pools. That 2% rebate matters.

But on top of that you are still one of the highest pool fees - 2%

So Any FPPS pool that is charging less than 2% (quite a few) is giving a higher reward, no matter what 'marking' lies you make up.

... and on top of that even your own site points out that luck on the last 250 blocks = 3.5 months, has been down 7.5%
So they are losing 7.5% there also, so no way are they making more :)

Feel free to argue yourself with that user (https://twitter.com/hoodmining/status/1507031754334421005). Unlike others, I'm not doing any "marking" lies (did you mean marketing? too bad, I'm not that).

With the rebate, it is 0%. And guess what, Partners have more options. But this is not a pool thread, so go back to the pool section if you want to waste time arguing instead of coding, People are waiting for the BM1398 BM1362 BM1366, get back to work so a product can be launched before the S21...

Bad mouthing Braiins Pool isn't going to bring you a single miner to yours (especially when you ban independent firmware), You know perfectly well how luck works. Its not 2015. I'm not allowing pool talk here anymore, any further comment about pool will be unceremoniously deleted, use the pool section. You don't see me trolling in your thread so respect mine.

Well I simply responded to your own comments about other pools.
OK, if you don't want pool talk here - don't start it :)

I would like to know what are the requirements for the new API calls Pause/Resume? Tried to find in the docs, but not yet there.
I mean what needs to be activated e.g. dynamic hashrate/shutdown/etc. Doesn't seem to stay off when there is a simple W target.

API docs here: https://github.com/braiins/bos-plus-api

Trying to get Braiins OS+ running from SD card S19J Pro with Beagelbone control boards. I got the BB version and flashed the image onto an SD card using balenaEtcher. Can't seem to get the miners to boot from SD card. They boot into stock Bitmain OS no matter if the SD card is inserted or not.

Is there something else I need to do to tell the miner to boot from the SD card?

**Edit/Update** Seems to be a problem with the type of SD card used. I tried another card and got it to boot from SD.

Now I am having another issue, on one machine it won't mine and I see the following in the log. Any idea how to fix this? The machine works fine with Bitmain's OS:

Looks like unsupported variant, or it can't read the EEPROM for some reason, bad cable connection, corrupted eeprom, etc. Try swapping the ribbon data cables.

SD cards can't be SDXC or later thanks to Bitmain. Just SDHC or SD; in layman terms, 16g max (a few 32g may work, nothing bigger).

got an email from braiins today . you will be able to remote load. just like you remote load bitmain os.

i will test over the week end

There are links and instructions for using the new braiins-toolbox in the first message of the thread.

I have installed BraiinsOS on my S19k Pro, but no other pools other than the v2 stratum on Braiins Pool is working. They all states "Dead"

Is BraiinsOS only working with Braiins Pool?

Edit: I got other pools working.

Hello, Installed OS with new toolbox on 10+ devices easy but I have few Zynq s19s that is unsupported, is there a plan to support it or how should I update them also?

Hello there, i have a little trouble, i bought a 64GB SD Card, is it too hight to flash braiin's os?

16 or less is better


https://www.amazon.com/dp/B07YYLLQN6?  


these work okay.


https://www.amazon.com/Pack-SanDisk-Memory-SDSDUNB-016G-GN3IN-Wholesale/dp/B01IMKEMC6/ref=sr_1_4?

You don't need sd to install on Zynq anymore...

Dear sir,
how to flash the xilink board on a s19xp? Or maybe i have just to boot on SD card, but will it work?
regards

Hi,

is the OS already for S19 Hydro or not?

Thank you for the info.

Currently, you can't flash any s19 series with braiins but you can boot braiins OS on sd card.
You can find the guide under this link below

- https://academy.braiins.com/en/braiins-os/installation/install/#install-braiins-os+-on-s19-series

This unit model is not yet listed on their current supported units check the list of supported units below. Why not try to boot Braiins through SD card and lets see if it would work?

- https://academy.braiins.com/en/braiins-os/about/

I have yet to buy a miner and therefore cannot try it out. So far I'm dealing with ROI after halving and even with $0.09 per kWh, S19s are already pretty bad.

You can install using Braiins toolbox (https://braiins.com/toolbox) to any of the control boards.

Running from SD is optional for BeagleBone Black and Zynq.

Hydros are "work in progress", no model is supported until announced. Supporting a miner cleanly from scratch takes a lot of effort and time, it cannot be done quickly. The manufacturer does not provide technical documentation and even obstructs independent firmware development.

Hello,

I am trying to find a way to flash BraiinsOS+ onto S17+ without leaving micro-sd in, to avoid having to spend $300+ on many micro-sd's.

I have read little bits about flashing with BOS+Toolbox, and something about flashing to NAND. But I get lost as im not too technically knowlegable.

If someone could give step by step instructions, or a link for how to, that would be great. Thanks.

In the first post you can download the sd image for x17 which is 22.05, you can install this to the miner if it has stock firmware, and the control board has NEVER been used with S19 fw (otherwise its permanently locked).

In that first post is the guide you need to follow as well (SD Method). It requires you inserting the sd, and use a browser to enter the miner and install to nand.

If you want a non interactive sd image that just installs then use this one (https://feeds.braiins-os.com/22.05/braiins-os_am2-s17_sd-install_2022-06-20-0-288861e4-22.05-plus.img) instead which just flashes to the control board and nothing else, you have to wait for the leds to blink which indicates the flashing is done.

If you install Braiins OS+ to the NAND of the control boards, the only supported uninstall method is using old bos-toolbox (link in the first post). Anything else, like sd_recovery from the manufacturer can leave the miner in an unusable state, which is remedied by installing Braiins OS+ again from sd and then use the only supported uninstall method. Do not use any other methods, especially those from 3rd parties.

If you want to upgrade after Braiins OS+ is installed to nand, you MUST use old bos-toolbox, and in the INSTALL tab type version 23.01 which is the final version for x17, you CANNOT use any later version than this. There is not much difference from version 22.05 and 23.01, just smoother fan operation.

These comments are only valid for the x17 family and have nothing to do with x19.

Flashing firmware is a delicate matter, maybe you should find someone with knowledge to help you.

so I purchased a controller from altairtech.io it is a braiins+ controller.


https://altairtech.io/product/bcb/

it is not working on my s19pro

I have

You have no connection to licensing server!


on one page

and

Unknown variant of stm32mp157c-ii1-am2 platformHostname: miner-d0050

on the dashboard page

 ideas on a fix


I changed miner to

 hostname s19pro

The licensing server message always shows when a miner is not recognized, but its not the actual problem.
The problem is that your miner is not supported by the BCB100, because the BM1398 is currently unsupported.

If you do have a miner with 5nm BM1362 (ie. S19j Pro) or BM1366 (XP v 1.0) you can use it now with the BCB100.

More modern miners will be supported when a firmware upgrade gets released for it, notably the XP v1.01, K Pro and jpro+ (which requires bos 23.10 or later).
The devs said it is possible to eventually support the older 7nm chips, but it would take more time, so i think its best to simply skip BM1398 for the time being (those are the oldest S19 miners).

Did the Altair site not say anything about BM1398 not being currently supported?

PS: BCB100 doesn't pay devfee, so normal pool fee applies.

API query - correct syntax for Braiins pool

I would like to use the API to check the status of the miner from the pool. I don't have Braiins OS and I can't get the syntax right.
I did find a tutorial at https://academy.braiins.com/en/braiins-pool/monitoring/, but it doesn't work.
I have created the API token.

My query is as follows (API token is changed to blabla)

https://pool.braiins.com/accounts/profile/json/btc/ "SlushPool-Auth-Token: <blabla>"

Tnx

Sorry Braiins OS only here. For pool questions you need to open a ticket in the pool.

I see the beta 24.02 for S19 Pro+ Hydro is out and is there any registration required?
Second question . is there also support for the S19 Pro Hydro 180 chip pair?
Thanks

No to both.

If you have the S19 Pro+ Hyd. (this also uses 180 bm1362 in each of its 4 hashboards) please test it with one miner first and share your results. Preferably dm me in the telegram support group so i can add it to the reports file.

Seen in the wild so far: T21, S21, S19k Pro, S21 Hyd.
