WARNING: Due to specific requirements of the supporting back-end program "sgminer", you can not run NiceHash Miner through Windows RDP (Remote Desktop Protocol) if you are using AMD GPUs. If you still wish to use remote access to you computer while running NiceHash Miner we suggest you to use TeamViewer: https://www.teamviewer.com.
As a back-end NiceHash Miner relies on the NiceHash.com service. By running NiceHash Miner you're essentially selling the hashing power of your CPUs & GPUs to hashing power buyers. Those are using the hashing power to mine various cryptocurrency coins and support decentralized blockchain networks - similar to cloud computing - only that by running NiceHash Miner you're actually being a provider for the cryptocurrency mining hashing power. You are being part of a global compute power network, empowering decentralized digital currencies.
Click 'Settings' button. NiceHash Miner will be relaunched with the ability to modify configs. Alternatively, you can manually modify config.json file (close NiceHash Miner first).
| Parameter | Range | Description |
|---|---|---|
| DebugConsole | true or false | When set to true, it displays debug console. |
| LessThreads | 0 .. 64 | Reduce number of threads used on each CPU by LessThreads. |
| ForceCPUExtension | 0, 1, 2 or 3 | Force certain CPU extension miner. 0 is automatic, 1 for SSE2, 2 for AVX and 3 for AVX2. |

| HideMiningWindows | true or false | When set to true, sgminer, ccminer and cpuminer console windows will be hidden. |
| StartMiningWhenIdle | true or false | Automatically start mining when computer is idle and stop mining when computer is being used. |
| MinIdleSeconds | number | When StartMiningWhenIdle is set to true, MinIdleSeconds tells how many secunds computer has to be idle before mining starts. |
| SwitchMinSecondsFixed | number | Fixed part of minimal time (in seconds) before miner switches algorithm. Total time is SwitchMinSecondsFixed + SwitchMinSecondsDynamic. |
| SwitchMinSecondsDynamic | number | Random part of minimal time (in seconds) before miner switches algorithm. Total time is SwitchMinSecondsFixed + SwitchMinSecondsDynamic. Random part is used to prevent all world-wide NiceHash Miner users to have the exact same switching pattern. |
| MinerAPIGraceMinutes | number | This is to give time for sgminer's API to start up properly as it takes a bit of time to (if needed) compile and load the bin. |
| EthMinerAPIGraceMinutes | number | This is to give time for the ether-proxy to properly start up. Increase this value if you are mining ethereum on slow GPU or if your ethminer keeps restarting. |
| DisableDetectionNVidia5X | true or false | Set it to true if you would like to skip the detection of NVidia5.X GPUs. |
| DisableDetectionNVidia3X | true or false | Set it to true if you would like to skip the detection of NVidia3.X GPUs. |
| DisableDetectionNVidia2X | true or false | Set it to true if you would like to skip the detection of NVidia2.X GPUs. |

| Groups\Algorithms\ExtraLaunchParameters | text | Additional launch parameters when launching miner and this algorithm. |
| Groups\Algorithms\BenchmarkSpeed | number | Fine tune algorithm ratios by manually setting benchmark speeds for each algorithm. |
| Groups\UsePassword | text or null | Use this password when launching miner. If null, default password 'x' is used. |
| Groups\Algorithms\UsePassword | text or null | Use this password when launching miner and this algorithm. If null, Groups\UsePassword is used. |
| Groups\Algorithms\Skip | true or false | Set to true if you would like to skip & disable a particular algorithm. Benchmarking as well as actual mining will be disabled for this particular algorithm. That said, auto-switching will skip this algorithm when mining will be running. |
Do not change any 'Name' parameters - changing them will not have any effect. 'Name' parameters are there only for easier config management.
If your CPU has 8 virtual cores and you would like to mine only with 7:
Set LessThreads to 1.
If you would like to set lower starting difficulty for ScryptJaneNf16 algorithm because your CPU is slow:
Set UsePassword to "d=0.1" under Algorithms item that has Name "scryptjanenf16" for all groups with Name "CPUx".
If you would like to manually configure intensity parameters for your three NVIDIA video cards (Quark algorithm):
Set ExtraLaunchParameters to "-i 19,19,19" under Algorithms item that has Name "quark" for group with Name "NVIDIA5.x" or "NVIDIA3.x".
My NVIDIA video card(s) is/are not detected.
Make sure to install latest official NVIDIA drivers from here: http://www.nvidia.com/Download/index.aspx Also check weather your card has Compute capability (version) 2.1, 3.x or 5.x, check here: https://en.wikipedia.org/wiki/CUDA#Supported_GPUs
My AMD video card(s) is/are not detected.
Make sure to install latest official AMD drivers from here: http://support.amd.com/en-us/download Also check weather your card supports OpenCL, check "OpenCL" column here: https://en.wikipedia.org/wiki/List_of_AMD_graphics_processing_units
I am having issues with my AMD GPU drivers.
We recommend you to use 15.7.1 version of AMD GPU display drivers. The latest Crimson drivers are also supported, but optimal speed for the majority of algorithms can be achieved by using 15.7.1 version. This version can be downloaded here. When uninstalling or reinstalling display drivers we suggest you to use Guru 3D Display Driver Uninstaller. This utility will make sure you get a clean driver state. You can download it here. If you are using Windows 10, the AMD installer utility is sometimes unable to install drivers, therefore you have to install them manually. Download and run diver installer, let it extract the archive and then cancel it when prompted to execute actual install. After this go to Control Panel / System / Device Manager, Right click on your GPU, choose to Update driver manually and point to c:\AMD[driver version] folder to finish the manual driver installation.
I'm getting "Always ask before opening this file" when running NiceHash Miner
Make sure you un-check the checkbox "Always ask before opening this file" when NiceHash Miner is starting cpuminer, ccminer or sgminer back-end programs. This is needed because back-end programs will be executed several times while NiceHash Miner is running (auto-switching according to profitability and in case programs hangs) and you have to make sure these programs will be to executed automatically without your intervention.
My anti-virus is blocking the application
Some anti-virus software might block NiceHash Miner as well as supporting back-end programs (cpuminer, ccminer, sgminer) due to false-positive matches. All software, included into NiceHash Miner has been verified and checked by our team and is absolutely virus/trojan free. Our service is well established and trusted among users, therefore you can fully trust software releases that are downloaded from our GitHub repository: https://github.com/nicehash/NiceHashMiner/releases. However make sure you never download and run any files from other unknown sources! If you downloaded the software package from our GitHub repository you can simply resolve the issues with false-positives by adding the files sgminer.exe, ccminer_sp.exe, ccminer_tpruvot.exe, cpuminer_x64_AVX.exe, cpuminer_x64_AVX2.exe and cpuminer_x64_SSE2.exe to anti-virus exception list.
I'm getting "Enqueueing kernel" errors on AMD GPUs
If you have very low amount of system memory (RAM), especially if lower than 4 GB, than you might encounter this kind of errors:
Error -4: Enqueueing kernel onto command queue. (clEnqueueNDRangeKernel)
GPU 0 failure, disabling!
This is because the sgminer mining application, which is used for AMD GPU mining, requires a particular amount of free system memory (RAM) to be able to run successfully. We suggest you to upgrade your system with more RAM.
Ethminer is running on all of my AMD GPUs including ones that are unticked from the miner
This is a limitation in the ethminer where in order to pick individual GPU, the ethminer would have to be run in multiple instances. To disable a certain GPU from mining, please disable the GPU directly from the Device Manager.
My benchmarking resutls are not accurate
Any kind of automation can only be done up to a particular level. We've spent significant effort to make benchmarking as good as possible, but it can't be made ideal. First of all, make sure to run Precise benchmark if Standard benchmark is not giving you satisfactory results. If you still see a deviation of actual mining speed from the one, calculated from benchmark, then you should manually enter these observed speed numbers from actual mining into config.json file or set them via the "Settings" button.
Benchmarks on particular algorithms keep getting terminated on AMD GPUs
In some particular combinations of Windows version + AMD Driver version benchmarks on some algorithms keep getting terminated. If the particular algorithm that is being terminated is shown on pause on the front page of NiceHash.com (No orders - mining unavailable), then this is normal expected behavior. However, if benchmark is also terminated for active algorithms, then you have to apply workaround solution. The solution is to copy all .cl files from the [..\bin\sgminer-5-3-0-general\kernel] folder into [c:\Users[your_username_here]\appdata\local\temp] folder and then re-run the benchmark for the algorithms that are terminated during benchmark.
