Hi,

I've done some work on s15, opening ssh and overclocking it: https://youtu.be/UJv6rrUNU60

Your mod might work similarly, a video would be welcome to see that it's actually doing something.

My suggestion is to keep this under control, small miners can open ssh with serial console easily if they need it badly, but it will be a pain for big mining facilities if this gets fixed in new hardware and firmware.

Good luck with whatever you're trying to do, but make sure you're not releasing "Just another fishing trojan" and mean it when you say you want to do some good to the community.


I somehow disagree with that. I though in the past that I will be helping the community by making a video on how to compile Bmminer because github docs from bitmain were unbiguous then after a short while, "custom" firmware were popping like mushrooms. Took the video down for a while but others started to repost the video cuz they saved it.

Sometimes it's better not to mess with things because you might do more harm than the intended good.

IMHO at least, other might disagree because they need such solution. I am part of the asicfreeware.io telegram chat where there's a bounty for opening s15.

I actually been part of developing a solution to overclock s15, https://www.youtube.com/watch?v=dbriKlQ-2hg done it, but too less people participated to the bounty and it does not make any sense to release it for free if people don't actually need it as it might be used in other harming ways in the future. I figure if people really needed such solution, would've donated at least $5 for seeing this project go together. The bounty is pretty much stuck and John and Scott put quite some work in promoting this stuff.

So my giveaway for this is becareful what you wish for.

Hi,

My name is Alex, I have converted a mining equipment to be water cooled and it has a great potential
to be used as a water boyler which mines BTC.

I started working on this project last year. I already work with an investor which funded the R&D and partially
the first version of the device. I also put my own money into this project, 9 000 USD, total invested so far $30 000 and
6 months of work, iterating over 3 versions of waterblocks and configurations.

Right now we are looking for an investor which can bring this project to the next level, we have the software and hardware skills,
but we need to purchase equipment to manufacture the parts locally in order to get them to the customer at a decent price
in order to perform mass sale. I have machining skills, I own 1 cnc machine but is not capable of fast milling and provide the finishing
required for mass production.

The amount we are looking is between 50 000 and 300 000 USD . 50 000 would allow setting up an assembly line and parially producing
the needed parts. We have a business plan put together and will be shared with the potential investors.

Here are some videos of the project:

If we get our own manufacturing line, we can fast develop solutions for other miners including the newest boards for S15 from Bitmain.

Drop a reply of PM if you are interested or join this discord channel:

I wish you the best!

You can flash the original firmware or extract bmminer file from a regular machine and use it with the deployer.

You are welcome! I played a bit with the gpu code, that is rocketship code for me, but I managed to understand that I cannot change it easily to
do random addresses as the stride is set at the initialization of the GPU node (not even sure if it's possible or if it's pheasible with the way gpu work is done). So I will use at intended . I set a random stride and nextKey using the generatePrivateKey(); so it generates a new set everytime the app is launched and counts at the random next key.

I am using GTX 690X, launched the app twice, with 1 app per node (gtx 690 has 2 nodes) and I am getting a total of 80 Mh/s.

I though it would be cool to link this with the blocksci, but I think the way you made it work with loading the list into the memory of the GPU is much more efficient than doing queries to blocksci.

Best of luck with your project, it's very nice of you that you shared the code, as I see it was a lot of work involved.

Nice job with the tool! It's perfect to work on something for hobby. It's modern lottery run by computer, I sent my thanks to your BTC wallet as well.. In case I find any lost wallet I will split proffits ).

Hi, I have not tested that feature on T9+ unfortunately. Might be different because of the controller.

Ya, it's actually the LPM which doesn't like overclocking on some boards, especially the 13.5 machines or older 14TH.

I plan on putting some more work into finding a solution for this in the following weeks, until then, the best solution for LPM is
the original firmware on bitmain without overclock.

There are some users which were lucky and it worked, so always test on a few machines before mass deployment.

Hi, I updated the main link as I removed that file from the server, this is the latest deployer: http://torrent-miner.com/tools/Antminer-MassDeployer-v.1.0.zip
and here you can watch a video on how to use:
https://www.youtube.com/watch?v=XkB6ymB01c4

Hey guys, here's a video I've made on how to enable 3 extra connectors for any Antminer S9 controller which have extra ports:

Hi, make sure you flash the original firmware before applying this patch, may users had other overclocking mods which are
not allowing this one to work. You can either reset to factory or flash the autotune version for your miner.

There's no source code for this yet, I was able to disable fan check by modifying binary code and to overclock from the single board test.
Single board test code is available on bitmain github, and you apply same changes that I've applied on my video for bmminer.
The fan disable version is not made public, if offered only paid by PM or discord.

Good luck!

I think you tried when the tool was not detecting which miner version it is, s9 or t9. The latest one will know which bmminer to copy.

Hi, I do not have any screenshots saved of the kernel logs. You can install on a machine and check it out yourself.

I don't think it will work, single board test was compiled for S9. There are different options for T9+.

Try getting the single-board test from the package and the rest of the files and use your original bmminer with it. Single-board test should be able to overclock any bmminer

About people no trying the mod, probably because I am a newbie on this forum, and there are more established threads with overclocking topic.

Good luck!

Ya.. it's triky to get it working on some machines, needs debuging when is not working. We usually do a lot of tests for the farms we work with on deploying custom firmware. Good luck with your code! It's always the best to choose the tools that works for your case as what worked for others might not work for you.

In my tests I was using 675, getting ~14.2 with 1350W and 890mv on a 13.5 old machine on antpool or btc.com, slush doesn't like LPM yet. The wattage varies from machine to machine, mainly
lower Voltages will use less power.

Glad to hear you work on your version as well. Let me know how your version works, it's indeed nice if you can set it just from the minerconfiguration.cgi, I did not check that as there are some funky ways of setting voltage on the PIC. Does your version work with LPM as well ?

Good luck!

Hi, the voltage and freq is being set from outside bmminer on this version because of the closed source code which was not released yet, you are not going to see in the logs of bmminer saying the voltage. You will see a message called Custom Overwrite set pic voltage=%d on chain[%d] where the logs for bmminer starts after it finished booting.

The nice part of this firmware mod is that it should work with any version of bmminer, just replace the single-bard test file (and the interface files) on your regular firmware and is going to overclock voltage and freq, making it
easier for those antminer s9 versions which were not compatible with the open source firmware.

Alex

You are welcome! I have some users which said it did not work for them, but I think they did not set the voltage for their machine, and some machines won't start with the default set
by bmminer or something.. Trying to figure out what is their issue.

Good luck!

There are some repair shops around, check the forum for that.

The thing is that the s9 firmware should not start the on the T9+, at least the ones I did before, this one is from
bitmain, so maybe they changed stuff..
