To any NiceHash Miner (NHM) users that are experiencing issues with AMD cards not being detected or having fatal errors during NHM startup (.NET exception or "Unhandled exception when querying AMD OpenCL"): Download this patch and just replace NiceHashMiner.exe in your existing folder NiceHashMiner_1.2.2.0 with .exe from this link. Please report back your findings if it fixes your issues. Thanks for the feedback! p.s.: this is a patch for bugfixes only, no other improvements, no need to upgrade if NHM is working fine for you Best regards, NiceHash team. |

With latest version I can't set successfully cpu-afinity :/
--cpu-affinity 0xaa (use 4 cores from i7 cpu), still cpu miner launches 8 threads and consumes 100% of cpu
giving 4 threads works, but affinity is not working
First of all, for CPU mining it is absolutely recommended to disable HT - it will give better per-core performance and also overall performance. Furthermore, to lower the number of threads, use "LessThreads" parameter, see https://github.com/nicehash/NiceHashMiner#options. |

Everything work fine ! Good hashrate !
But a litle problems: NH miner always mine Lyra2REv2 in any case. I wait for 15, 30 minutes but it's not auto switch to X11 when it is the best profit.
Profitability is local to your own rig. If X11 is shown as best profitable on NiceHash.com home page this does not mean that it is most profitable for you, too. Your rig - your gpu(s)) have a specific profitability and NHM will mine on the algorithm that is most profitable for your rig. The algorithm that is shown as best profitable on NiceHash.com it's just an general average. |

That minner become better with every version so far! Can i get some instruction how to apply my overclock settings? If that matter i use 4x R290 tri-x cards and i want to oc every card individually from MSI afterburner. Or maybe in the next version you can make it overclockable  I try oc now, but the miner reset my setting immediately. Stop NiceHash Miner and edit config.json file. See the configuration of sgminer startup parameters for each algorithm at the tail of the file. Add " --gpu-xxx VALUE" parameters for each algorithm ... see here for details: https://github.com/nicehash/sgminer/blob/master/doc/configuration.md#gpu-engine |

so if there has been no request for it - here it is ... can you supply the code used for the sgminer app that you distribute as closed source software? ...
chrysophylax, please read our previous message on this thread ... if we would have the sources we would of course already supply them ... the developer of the optimized kernels will not release them, unfortunately. Giving you the miners with bins is the best we can do - that's all that we have. Best regards, NiceHash team. |

I'm mining with hd7950 and hd7970 cards, using latest amd drivers and latest nicehash miner. I should mention that when worksize is changed, miner doesn't start.
Are you getting "Enqueueing kernel" errors on AMD GPUs? If yes, take a look at the Troubleshooting section: https://github.com/nicehash/NiceHashMiner#troubleshooting |

Nicehash, where's the sources to the exe's you pack into NiceHash Miner? The license stipulates it be available at least upon request. Not the bins, but the SGMiner executables.
The sources for sgminer-5.2.1-general are here: https://github.com/nicehash/sgminer/tree/windows. Unfortunately we don't have sources for sgminer-5.1.0-optimized and sgminer-5.1.1-optimized, because kachur never releases his sources. You all know that we are big open source supporters, we are contributing to open source software, we also release our own sw under open source and we support developers as well (made several tips for many developers in the past). Now, regarding this closed-source sgminer that we're redistributing with NHM -> yes, we know that this is not the fully rightful thing to do - but this way we can give the optimized miners to community and anybody can mine on any pool with these miners. Moreover, before we distribute any closed-source miners we always make a full network sniff of the working miner to make sure that no fake-shares, hidden-pool or any other suspicious stuff isn't plugged into the miner. Hopefully that's OK with you folks, that's the best we can do. Keep on mining!  Best regards, NiceHash team. |

About the new optimised kernels: I assume they are precompiled bins as usual, but what about the miner part that runs on cpu? At least for quark some kind of host code is needed, for it to hash that fast. Is that code opensource and merged into sgminer main branch?
It's source; mine. Exactly. sgminer is more or less unmaintained, but you can find neoscrypt.cl in the kernel folder of sgminer-5.2.1-general in the NiceHash Miner. We prefer to keep all opensource, so you're welcome to reuse it anywhere. And of course Wolf has all the credits for the optimized version (but his work was decently paid by us). |

OK, now this is another error, looks like networking issue for cpuminer. Can you try Europe or any other location? |

The new version is crashing on rigs wich need --gpu-platform 1 as a parameter in sgminer.
1. gpu-platform 0 is the motherboard gpu.
2. gpu-platform 0 is a NVIDIA card.
As far as we have tested this only happens on Win10 and it also depends on the order of drivers installation ... The workaround for now is to disable any other GPUs in the system if you wan't to use your AMD GPUs. sp_, do you know of any decent method in C# to retrieve all OpenCL platforms with names and IDs? |

Hi, Take a look at the great Scrypt profitability at NiceHash! And it's PPS! > 15% more than direct Litecoin mining! Don't miss this great profitability!  |

Hmm, which OS version are you using? Which GPUs do you have in the system? Also, can you post what is shown when you click "Details" on this issue? Also, if you reboot your PC, does the issue persist? |

If we go to settings/config/groups/4/algorithms we will see, what in ANY algo ExtraLaunchParameters set for keccak! Of course this miner will not work with AMD  What exactly makes you think that it wouldn't work with keccak algorithm? |
|
|

when running both CPU and GPU mining, when all CPU cores are being used it drops GPU hashrate, is it possible when X less CPU threads are being used, the GPU miner to have affinity to use only those free X CPU cores.
Sure, see Config parameter LessThreads: https://github.com/nicehash/NiceHashMiner#options ... so if you want one core to be free, set LessThreads = 1, if you want two cores to be free, set LessThreads = 2, etc. |

x11 = 11.4mhs
x13 = 4.2 mhs
keccak = terminated
nist5 = terminated
neoscrypt = 125 mhs
whirlpoolx = 102 mhs
qubit = 11.1 mhs
quark = 14.6 mhs
lyra2rev2 = 11. 9 mhs
AMD XFX HD7970 3 gb
These numbers are all very good, with the exception of neoscrypt -> this hash rate is wrong, neoscrypt should give a few hundred Kh/s, not Mh/s. Did you try this? -> delete all *.bin files in the "..\bin\sgminer-5-2-1-neoscrypt" folder and run runme.bat in the same directory. Do you see a speed of few hundred Kh/s (like 0.100 Mh/s)? If you still getting 100+ mhs on neoscrypt, then neoscrypt is obviously completely broken on win 10 (+some combination of drivers most probably). In this case open config.json in NiceHash Miner folder and enter "BenchmarkSpeed": 0.0, in the "Name": "neoscrypt", configuration section. This will effectively disable neoscrypt. |
