How to get&run it?

All you have to do is download, extract and run the miner (no installation needed), choose the server location that is the closest to your location, run built-in benchmark and enter your Bitcoin wallet address where you want to get your coins sent at - and you are ready to start mining and maximizing your profit.

Note: .NET Framework 2.0 or higher and Microsoft Visual C++ Redistributable 2013 is required. No additional installations should be needed if you use Windows 7 or later. However, if you encounter any issues when starting application (application would fail to start or errors/warnings about missing DLL files are displayed) you should download and install Microsoft .NET Framework 2.0 and Microsoft Visual C++ Redistributable 2013 (vcredist_x64.exe) (after installation a reboot might be required).

Detailed instructions:

WARNING: Due to specific requirements of the supporting back-end program "sgminer", you can not run NiceHash Miner Legacy through Windows RDP (Remote Desktop Protocol) if you are using AMD GPUs. If you still wish to use remote access to your computer while running NiceHash Miner Legacy we suggest you to use TeamViewer: https://www.teamviewer.com.

Where is the profit coming from?

As a back-end NiceHash Miner Legacy relies on the NiceHash.com service. By running NiceHash Miner Legacy 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 Legacy 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.

How to run NiceHash Miner Legacy only when profitability is high enough?

Profitability of mining can go up and down that may be unprofitable to mine especially places with high electricity cost. By using the "MinimumProfit" settings, NiceHashMinerLegacy will stop mining if the current profits are below the minimum amount (in USD). This will help you mine during "profitable" times only.

Additional options

Click 'Settings' button. NiceHash Miner Legacy will be relaunched with the ability to modify configs. Alternatively, you can manually modify \configs\General.json for general settings and \configs\benchmark_XXX.json (XXX is your device UUID) files for device benchmark settings (close NiceHash Miner Legacy first).

Troubleshooting

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 whether 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 whether 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 Legacy

Make sure you un-check the checkbox "Always ask before opening this file" when NiceHash Miner Legacy is starting cpuminer, ccminer or sgminer back-end programs. This is needed because back-end programs will be executed several times while NiceHash Miner Legacy 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 Legacy as well as supporting back-end programs (cpuminer, ccminer, sgminer) due to false-positive matches. All software, included into NiceHash Miner Legacy 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/NiceHashMinerLegacy/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.

My benchmarking results 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 behaviour. 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.
