Antminer D3 Blissz firmware (10/12 v1.12 update)

[junforever]

@blissz Again congratulations for your work, I will start checking the code too in order to find a solution and try to rescue our "beloved" d3, if someone has some knowledge of programming could help to find the file where the algo manage is, in order to find a solution (if exists) as far as we can, if we want to rescue our money (thing that bitmain shows clearly not interested) all of us who know about programming must colaborate instead of wait just one person effort.... At the end if we can change the firmware all of us are going to win this is the source code of the cgminer for D3 https://github.com/bitmaintech/cgminer-dash

I had just asked that from ck (official cgminer thread)but it seems , he is not the guy we needed

where could we download the D3 mod？

[esconceptsz]

I have some great news guys!  

I successfully modified the following:

- unlocked ASIC voltage from software. You can now increase or decrease the ASIC voltage from software
 This can save a lot of power / heat and noise. i.e. I run my D3 at 15Gh/s at below 700 watts instead of 19Gh/s @ 1200watts. On the other hand you can also decide to overclock your unit if your PSU can handle it with this unlocked vcore.
- removed fast FAN startup. (very annoying for users that run this miner at home)
- unlocked full fan control. No more minimum fan checks. It removed the low fan warnings as well.

I need to mod the webinterface as well and do some testing so it will take roughly one more week before I will release the first firmware version I guess
This first version is mainly aimed at home users to get a better power usage / hashrate balance and run it as silent as possible
 
before you ask: Adding new algorithms will be on the list for future versions

other feature requests are welcome of course

You'll certainly get a donation from me if this all comes together!

Is it possible to finish D3 before X11gost. Sources of it for the X11ghost cgiminer are also on github. Only one algorithm was added. Would be a good profit.

[dlethe]

Well, i studied the source code.   Assuming that the source code is complete and this is the ONLY program that interfaces with those 80 microcontrollers then yes, absolutely it is possible to change the algorithm. (But there are limits due to the tiny amount of RAM and flash RAM on each processor)

But here is the deal.  It is a pain.  I'd have to get some development hardware to facilitate this, and probably brick a D3 (or two) in the process.

The big caveat, as a first step, is to be 100% sure that the code you referenced is the actual code that is running, and there are no undocumented daemons running that interact with the micro controllers.

So here is the test..   Can you recompile the unmodified software and get same checksum and binary?  (Note, you may have to set some compile flags to match any __DATE__ type macros.  My concern is that we really don't have all the code for the mining software in GitHub.  

Here is the other concern.  Bitmain could easily put in a sorta poison pill in a later firmware update (or for all I know, one of the programs that is already running under their LINUX O/S is listening for a internet-based kill switch that can make reprogramming the D3 to use different algorithm impossible).    So anything further on the subject would be unwise.

Suffice to say, I know what I am doing, and I am intrigued by the possibility (I have 2 x D3s).  Now some algorithms are totally impractical for this hardware, and it is way too early for me to commit to spending more time on it.  

I also see some opportunities to improve and optimize the code so it will take fewer clock cycles to crunch, and/or do more crunching in the same amount of time.    I don't know whether it would be significant w/o profiling and that would be a pain.    There is very little code written in assembly language.

Anyway, no commitment, but I am awaiting word whether or not a straight recompile gives us the same binary the latest firmware is running.

Hi
as of now more than 500 people invested their money to this shit.This means more than millions $ money. I can't speak behalf of them but I can say for myself , I can pay money for this firmware.So this work  will not be free of charge if it is succeded.
Let say 50$ for each unit. Does not worth it to try ?

[cryptonitro]

has i see no one try to help ... i just remove the warranty of my brand new D
don't know if it will be good for you , it seem to be at 9.50~ at startup and then 7.99~8.00 when mining




please let us have basic set up or how to do... to dont hear those damm fans ...

the r80 is very little , i m scared to touch it ...

[caymanguy]

no one try to put the control board of l3 on D3

i mean if D3 can be process like L3 so we can implement asoftware to do mining using the D3 processing board for different algorithm

so we hack the firmware in both cases we will not loose anything for bitshit uselless unit i bought for 5000 $ 2 pcs 10000$


thx

Dear BLISSZ

Thanks a lof of you work. All we are waiting new ALGO on D3. Have a good news about this project?

[Ryancope123]

I would also be willing to pay good money for a firmware update that supports more algo's !!


Get this done and you will be a very rich man =)

i hear nodel coin is x11 coin and we can use d3 to mine it with profit of 10 dollar aday but i dont know how to do it

I think the algo for mining is on PIC16F1704 not in firmware file ... anyone can read and post file of PIC16F1704 ? I think we need work on this ..

i can get a D3+PSU for  1575$US should i buy ?
i got mixed feelings , reading this thread.

[dashcoin1]

a small update on some questions I got:

- overvolting & overclocking will be possible as well. This doesn't make sense for me, but as long as you can keep it cool enough, it will be fine.
- I will add more features to the webinterface after the first version
- for now it's only tested on the October batch, but it will work for sure on other batches as well.

The status is now is that the I can adjust the voltage by hard code it in the binary, but it really needs to be a proper setting in the advanced webinterface page first before I send it out.
Fan speeds are fully unlocked already, so you can also decide to change them to a pair of silent fans on the modded firmware.

where could we to download this mod

at this very moment id say no, but if this works out........YES

[sangwookie]

Thanks for this. I will look into it. But with the
 Recent rise in Dash and the new X11 ICOs, I think it might be best to keep the having power and make a sound proof box with ventilation.

what are these new x11 ICO's of which you speak? mineable? (I need hope damn it!) (sorry...stressed)
