Hello, NiceHashSupport! It seems to me your sha256 stratum server pushes the difficulty too high. I've made some tests with my S5, and it performs the best with the diff ~ 2048, but your stratum server always pushes it to 4096 and chokes the S5 to below 1 Th/s average. Tests on other pools with the fixed diff 2048 yield much steadier and nicer results, close to 1.2 Th/s. Am I missing something here, or could you please keep the difficulty at around worker's hashrate in Gh/s * 1.8 - 2? Thank you!  |

This is not a diff problem, but specific S5 problem, that has been reported multiple times. We suggest you to push this matter to Bitmain so they fix their software.

Thank you very much, good to know the roots of the problem. |

I keep asking BMT to give US BFG support for whatever reason they won't there is a few things BFG does that are nice that CGMinder doesn't do and may never do that is BFG only or seem to be one is GBT support at least i can't get GBT to work with CGminer . i would rather use BFG inside any ant, not thu a Proxy. but not why i ask for it ,I like being able to have that choice but if i want to use any S series BMT stuff which i do, i have to use CGMINER ( I have nothing against CGMiner ) unless I use BFG in a Proxy. |

Solo mining? Easy, put in /etc/init.d/cgminer.sh in PARAM section after --queue --btc-address your_wallet_address. Looks like bitmain ignoring all questions related to source code of firmware( violating gpl licence btw) Also, we have bitmain driver code, we could just port it to bfgminer. |

Luke told me thy told him there is not enough who want it to give him the info he needs I find that hard to believe, that they actually think that, I believe him and believe that is there excuse, no disrespect @ BMT either.. so i ask from time to time and hope. |

btw you all were right H2C just fixed the low DIFF with two coins and one was 42 . and more . - optimization for coins with low block time (42, DGB, etc) I'm guessing the low block time was the issue. |

toptekk, So we need to port driver from cgminer to bfgminer that's all. For skilled programmer i think there is no problem to do that. At least bitmain uses linux, and cgminer, look at the silverfish 28 mh/s blade for scrypt, hardware is cool, software is awful, no cgminer/bfgminer at all!

I'm about to buy two of those have been looking , it does. ebay has some for sell at a nice price and very little power use age, i just hope in month once, i have the cash to gather i can still get one at least if not two . |

If you talking about silverfish, stay away from them, awful software, no support at all. Better look at gridseed g-blade, maybe this is not the best option, but at least it support opensource software. |

I want to mine both coins . TY for the tip on the SF miner. |

I think I've solved it! My S5 was connected to a local stratum proxy with #xnsub in the URL. I simply removed it and things got MUCH better instantly. Now the stratum proxy disconnects the S5 on each extranonce/pool change, but the hash rate is as it should be. Tested with both the newest official S5 firmware and Smit1237's mod - the results are exactly the same. Hooray! |

If you're using stratum proxy you should consider using newer stratum proxy with extranonce support, see "Stratum-Proxy guide" here: https://www.nicehash.com/index.jsp?p=asic |

DRAGON MINER is using cgminer and the controller is embedded raspberry-pie. We don't have any newer cgminer with extranonce.subscribe for this particular device, but you could contact the manufacturer (or distributors) of DRAGON MINER to make new cgminer binary with extranonce.subscribe patch ( https://github.com/nicehash/cgminer-ckolivas/commit/4e9c7ce68ed91ec9189d83c35b2237aca65f2b7f), then you can upload new cgminer via SSH to embedded raspberry-pie controller ... maybe you could also ask some programmers (bitcointalk user smit1237) if they can provide such newer cgminer binary for this miner. |
