It would be good.


I founded voltage set,  and fixed here: (725mv)


cgminer must be recompile with this change:

For mining only one algo that's enough a modded cgminer?

Cgminer it's  embedded in the firmware?

Actually , this is the point. No one asks for SHA 256 , or scrypt algo ,  anyway

But looks likes its possible grs and keccak

And it's possible to mine only one of 11 algos? For example mining only with skein algo

No.

For add algo we need to update chips on d3 boards? It's possibile?

with the first firmware that will be out
can we run d3 at 700 watt with 15gh speed or not?

Maybe bad news...

Here is an example code to build an X11 hash:

void x11_hash(const char* input, char* output, uint32_t len)
{
    sph_blake512_context     ctx_blake;
    sph_bmw512_context       ctx_bmw;
    sph_groestl512_context   ctx_groestl;
    sph_skein512_context     ctx_skein;
    sph_jh512_context        ctx_jh;
    sph_keccak512_context    ctx_keccak;

    sph_luffa512_context      ctx_luffa1;
    sph_cubehash512_context      ctx_cubehash1;
    sph_shavite512_context      ctx_shavite1;
    sph_simd512_context      ctx_simd1;
    sph_echo512_context      ctx_echo1;

    //these uint512 in the c++ source of the client are backed by an array of uint32
    uint32_t hashA[16], hashB[16];   

    sph_blake512_init(&ctx_blake);
    sph_blake512 (&ctx_blake, input, len);
    sph_blake512_close (&ctx_blake, hashA);

    sph_bmw512_init(&ctx_bmw);
    sph_bmw512 (&ctx_bmw, hashA, 64);
    sph_bmw512_close(&ctx_bmw, hashB);

    sph_groestl512_init(&ctx_groestl);
    sph_groestl512 (&ctx_groestl, hashB, 64);
    sph_groestl512_close(&ctx_groestl, hashA);

    sph_skein512_init(&ctx_skein);
    sph_skein512 (&ctx_skein, hashA, 64);
    sph_skein512_close (&ctx_skein, hashB);

    sph_jh512_init(&ctx_jh);
    sph_jh512 (&ctx_jh, hashB, 64);
    sph_jh512_close(&ctx_jh, hashA);

    sph_keccak512_init(&ctx_keccak);
    sph_keccak512 (&ctx_keccak, hashA, 64);
    sph_keccak512_close(&ctx_keccak, hashB);
   
    sph_luffa512_init (&ctx_luffa1);
    sph_luffa512 (&ctx_luffa1, hashB, 64);
    sph_luffa512_close (&ctx_luffa1, hashA);   
   
    sph_cubehash512_init (&ctx_cubehash1);
    sph_cubehash512 (&ctx_cubehash1, hashA, 64);   
    sph_cubehash512_close(&ctx_cubehash1, hashB); 
   
    sph_shavite512_init (&ctx_shavite1);
    sph_shavite512 (&ctx_shavite1, hashB, 64);   
    sph_shavite512_close(&ctx_shavite1, hashA); 
   
    sph_simd512_init (&ctx_simd1);
    sph_simd512 (&ctx_simd1, hashA, 64);   
    sph_simd512_close(&ctx_simd1, hashB);
   
    sph_echo512_init (&ctx_echo1);
    sph_echo512 (&ctx_echo1, hashB, 64);   
    sph_echo512_close(&ctx_echo1, hashA);

    memcpy(output, hashA, 32);
   
}

As u can see, there are many sub algos affected to make an x11 hash. These algos are hardcoded in bitmains asic chips. So you can input some work and get outputted the result of the complete x11 hash.

I took a deep look into cgminer (also the newest version) and what i found was only to put work into asic and get results back. My hope was, that it could work like Baikalminer, but i was wrong here.

Good Luck

Great news  I happy  to hear it thanks for hard works.

this is the r80 , the one in place where blissz conntect blue and red cable
c948  revealing it if i m right , in do not let my cable on c948 , i cant took it

this is the c948 i took

If one can tell me the code on the resistor I can tell you the exact resistor value.

Thanks for this by the way, it would be nice if someone can confirm the original ohm resistance of R80. I thought it was 4.58K, but I am not 100% sure.
You can just measure it with the board turned off and you will be fine

OK, I have some Antheater to make a brick.

at the prices, we are getting now...and 4 or more batches of D3's in the wind yet to arrive and the corresponding difficulty pump

bricking them at this point may not matter much

Indeed, I should send mine to the company that 'bronzes baby shoes'

just to have a small trophy, when they stick me in the old folks home someday on a reminder of my 'silly youth'

Almost finished: the webinterface is modified as well now. Only need to test for a proper voltage range, and make a package.
The first release will have a fairly save voltage range, as I don't want you guys to brick your miners, so please have a bit more patience

Tested, don't worked.

thanks

did you register TO say that? lol
