Speaking of new firmware bitmain have finally fixed the xxx issue in a new update , interesting timing.
You mean firmware 20171102 ? I still have the problem even after upgrade. every 12h -15h card goes XXX |

Hi, I was following this thread for a while now.
@Blissz: I will receive 20x D3 within the next two weeks, so if it helps, I can spend one for testing purposes.
(located in Germany)
Another idea that I had, wouldn't it be easier to set up a programming from scratch instead
of trying to analyze if there are some hidden "mines" that will prevent us from being successful?
If I was bitshit, I would have placed several traps to prevent anyone modifing my hardware, even in terms of algos...
As far as I see, all programming is placed on a pi or arduino or whatever cheap but easy to
programm hardware they used. Buy a new pi for a few bucks and everything should work sooner than
by using Bitshits trappy controller.
I think it would be worth thinking about it. All necessery code fragments are already there.
What we saw, the most 'complicated' part isn't in the linux stuff ( we have the root access, the source code, we can recompile a cgminer or use sgminer etc..) but it's more in term of Asics programming, if they can handle the others algo... |

Hi guys, I am working on finalizing the first version of the firmware now. The first release will not contain any new algorithms yet, but will add some nice features to quiet the beast  It's still uncertain if adding other algo's is possible but I will definitely give it a try after the first firmware runs stable Great news, If you want some beta tester, I already made some modification on mine, so I will be happy to test. Cheers |

regarding bitmain-voltage parameters in source code it's look like
bitmain-voltage = 176 // so something like 1.76V
does someone can verify this?
yes, I checked, but not worked for me. I changed freq in cgminer.conf which is work fine, but bitmain-voltage not. Tested 176, 0176, 0725, 0625. Same 970w with 500 freq. I think we need to use another parameters. I saw into cgminer source code and looks like this: OPT_WITH_ARG("--bitmain-voltage",
set_int_0_to_9999,opt_show_intval, &opt_bitmain_DASH_voltage,
"Set voltage"),it should work, but I think there is something missing. yes the option is probably 'disabled', need to find where we can activate it. I will continue checking this tomorrow |

we are talking about possibility to adding more algos for D3 with this topic , not only fan mod , right ?
If think we should start from the beginning... fan mod...voltage mode so increase efficiency... then if it's possible add algo but not sure about this point and we are Ok to say X11 it a chain of 11 algo.... (blake, bmw, groestl, jh, keccak, skein, luffa, cubehash, shavite, simd, and echo.) so that mean the asics 'know' how to do some groestl algo... infact good poin ... we need know how change command (possibly via ssh) send a command to cgminer on d3 to change algo and try if mining work... anyone can help in this? We need more than this..in SSH you can restart cgminer with other parameters Aka : fan..or voltage (i have the parameters and a possible value for this) But in term of algo..i think we need to recompile cgminer from source (changing stuff to have only groestl for example) So it will require more investigation but I will continue on this please public this parameters do you have... into cgminer.conf you can use "bitmain-voltage" : "xxx" but Need to double check the default value (I think it's 176 => 1.76V) but don't do it if you are not sure |

Hello guys, we all know that D3 is limited to X11 algo we also know that X11 is a chain of 11 algo: blake, bmw, groestl, jh, keccak, skein, luffa, cubehash, shavite, simd, and echo. we also know that Baikal Giant X10 will be able to mine X11 and many of those 'chaine' algo... ( first investigation is ASICS are similar on BAikal & D3) So my idea is may it's possible to recompile D3 cgminer with only some of those algo all the source are here: https://github.com/bitmaintech/cgminer-dashAny of you already think about this? Please only use this thread for this subject ( we already have thread on D3 hardware mod etc...) |

yes in this folder you have the 11 algo code used for X11.... so need to recompile something with only groestl or other.... but i think something more will be needed ^^ |

regarding voltage did you tune using some custom parameters into /config/cgminer.conf
because editing freq & other parameters worsk fine in this file.
Did you get the default voltage applied to asic ship?
The. We can modify with bitmain-voltage" : "xxxx"

Got 2 running @ 475 so hashrate around 620Mh/s. temps always under 70, and less than 0.1% reject.
does anyone try more?

Very nice job Dude !!
do you have another picture of the soldering of potentiometer on the r80 slot?
Thanks

For mining Eth only, ethminer is doing better than Claymore or not? ( with AMD RX5xx GPU).
Thanks
