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

[cryptonitro]

sorry for the issue in the first upload, this should solve the issues. Thanks for the fast reaction time

Everybody that already "work" on the first uploaded 20/11 version, please upgrade again, as you won't be able to adjust the pools / fan speeds

working nice now

thanks for the confirm and thanks for the super duper cool logo man!

Today i tested the mod...
I have  3 Antminer batch 1 at 17.1 Gh/s
This is the comparison Before-After....

Asic voltage "Lowest" outside temperature 7 Degree celsius

Freq   Before mod                 After mod                  

487M  17.14Gh/s 941Watt      17.26Gh/s 861Watt ( some HW Error, about 200 after 10 minutes)                                        

450M  15.84Gh/s 855Watt      15.80Gh/s 791Watt ( 0 HW error)

400M  14.10Gh/s 766Watt      14.32Gh/s 708Watt (0 HW error)

Gain/Day  Dash WhatToMine with electricity cost 0.22$/Kw

Freq     Before    Total        After   Gain Dev     Total

487M                0.71          1.22    0.018         1.20

450M                0.73          1.10    0.016         1.08

400M                0.63          1.05    0.015         1.03

Is better.....and thanks,  but......
If there is not possibility to change algo i think that is not enought....

Bye!

Mr. blissz now only a test for one subalgo of x11 ... and we are the winner ;-)

...

Nice to see some results of the first batch. That is by far the best performing batch actually. But still nice to see a ~10% improvement on the custom firmware. You might be able to squeeze a bit more out of it using the latest firmware.

i second this motion

[mikespax]

Could you place decibel measurements on the first post? I'm curious as to how loud the various settings will be.

[maxfunky]

great thanks for this.
out of couriosity, have you done any mods for other miners, like ibelink 11g or baikal giant? ^_^
Cheers

oh god I hope someone bring us that kind of modified firmware for the DM11G ! 

[dawidt]

i hope it will be a little quieter.

[uipaymentreview]

Dear blissz!

Thank you for your fw its awesome and you deserve the fee. But can you please add function to set the fans speed separately? I investigated that the fan 2 is far more noisy than the fan 1 and the fan 2 is always spinning at higher rpms making the most noise. For example, L3+ fan1 and fan2 spinning almost the same speed and its more quieter compared to the D3 fans at same rpms.

Hence only mines x11 coins...

Well hopefully we can get groestl

X11 Algos

blake, bmw, groestl, jh, keccak, skein,   luffa, cubehash, shavite, simd, echo

[fecell]

Which tool do you use to unpack initramfs.bin.sd in windows 10?

winrar

stop dream with groestl(GRS) , seem i never tell that enough , they will change algo because of asic coming on their blockchain  , they are serious people
i don't know if Blissz have clue to get subalgo , but a good fork for some X11 coin be good to, as network is in fire

The D3 cgminer driver (released by Bitmain) doesn't even mention X11 or subalgorithms. You can check:

• https://github.com/bitmaintech/cgminer-dash/blob/master/driver-btm-DASH.c
• https://github.com/bitmaintech/cgminer-dash/blob/master/driver-btm-DASH.h

There is struct work_dash that contains interesting type field. However it has fixed unknown value 0x20.

Code:

    
struct work_dash
{
    uint8_t type;                           // Bit[7:5]: Type,fixed as 0x01. Bit[4]:sno valid   Bit[3:0]:reserved
    uint8_t wc;                             // bit[7]: reserved, bit[6:0]: work count base
    uint8_t work[WORK_DATA_INPUT_LENGTH];   // 0-75 bytes are dash work; 76-79 are start nonce field
    uint16_t crc16;                         // crc, but not include the header 0x55, 0xaa
};
//...

// BM1760 ASIC input data length
#define WORK_INPUT_TYPE_WITH_SNO                    0x30
#define WORK_INPUT_TYPE_WITHOUT_SNO                 0x20

//...

void *DASH_fill_work(void *usrdata)
{
struct work_dash workdata;
//...
workdata.type = WORK_INPUT_TYPE_WITHOUT_SNO;
//...
DASH_write(info->dev_fd[chainid], (uint8_t *)&workdata, WORK_INPUT_LENGTH_WITH_CRC);

It would be interesting to fuzz work_dash.type a bit, to see if BM1760 supports some other types. However probably this wouldn't do anything useful.

So IMHO this means unless there is secret golden switch inside chip BM1760, there is no way to choose algorithm.
BM1760 is Bitmain private chip. There is no public spec available, all they say about it is "BM1760 custom-made chip using 28nm technology."  

[Macfey]

Thank you for the mod firmware.
Would it be able to use on L3+?

No.

This firmware has nothing to do with the L3+.

Hi,

My place is cold but I use 110-120V electricity so could you please recommend me which fan speeds and voltage should I apply for my two antminer D3? I plan to place them next to a window.

Thank you very much!

thank you for infos!
I think we are close to the end of the discussion about mining other algos!

[dashcoin1]

The Scythe GT3000 speed fan will not work, but 100% speed setting???

All fans should work now actually, but they need to support PWM (4 pin wire) to adjust the fan speed

Why it's not calculated work for adjust to 2000 rmp speed?Unrecognized speed.

[Dash2017]

has anyone tried to bottle the D3 Miner with the original flash firmware from the L3 +?
