Ethereum miner with OpenCL, CUDA and stratum support

Ethminer is an Ethash GPU mining worker: with ethminer you can mine every coin which relies on an Ethash Proof of Work thus including Ethereum, Ethereum Classic, Metaverse, Musicoin, Ellaism, Pirl, Expanse and others. This is the actively maintained version of ethminer. It originates from cpp-ethereum project (where GPU mining has been discontinued) and builds on the improvements made in Genoil’s fork. See FAQ for more details.

OpenCL mining
Nvidia CUDA mining
realistic benchmarking against arbitrary epoch/DAG/blocknumber
on-GPU DAG generation (no more DAG files on disk)
stratum mining without proxy
OpenCL devices picking
farm failover (getwork + stratum)

The ethminer is a command line program. This means you launch it either from a Windows command prompt or Linux console, or create shortcuts to predefined command lines using a Linux Bash script or Windows batch/cmd file. For a full list of available command, please run:

Continuous Integration and development builds

CI	OS	Status	Development builds
Travis CI	Linux, macOS		✗ No build artifacts, Amazon S3 is needed for this
AppVeyor	Windows		✓ Build artifacts available for all PRs and branches

The AppVeyor system automatically builds a Windows .exe for every commit. The latest version is always available on the landing page or you can browse the history to access previous builds.

To download the .exe on a build under Job name select the CUDA version you use, choose Artifacts then download the zip file.

Building from source

Why is my hashrate with Nvidia cards on Windows 10 so low?

The new WDDM 2.x driver on Windows 10 uses a different way of addressing the GPU. This is good for a lot of things, but not for ETH mining.

For Kepler GPUs: I actually don’t know. Please let me know what works best for good old Kepler.
For Maxwell 1 GPUs: Unfortunately the issue is a bit more serious on the GTX750Ti, already causing suboptimal performance on Win7 and Linux. Apparently about 4MH/s can still be reached on Linux, which, depending on ETH price, could still be profitable, considering the relatively low power draw.
For Maxwell 2 GPUs: There is a way of mining ETH at Win7/8/Linux speeds on Win10, by downgrading the GPU driver to a Win7 one (350.12 recommended) and using a build that was created using CUDA 6.5.
For Pascal GPUs: You have to use the latest WDDM 2.1 compatible drivers in combination with Windows 10 Anniversary edition in order to get the full potential of your Pascal GPU.

Why is a GTX 1080 slower than a GTX 1070?

Because of the GDDR5X memory, which can’t be fully utilized for ETH mining (yet).

Are AMD cards also affected by slowdowns with increasing DAG size?

Only GCN 1.0 GPUs (78×0, 79×0, 270, 280), but in a different way. You’ll see that on each new epoch (30K blocks), the hashrate will go down a little bit.

Can I still mine ETH with my 4GB GPU?

Not really, your VRAM must be above the DAG size (Currently about 4.023 GB.) to get best performance. Without it severe hash loss will occur.

What are the optimal launch parameters?

The default parameters are fine in most scenario’s (CUDA). For OpenCL it varies a bit more. Just play around with the numbers and use powers of 2. GPU’s like powers of 2.

What does the —cuda-parallel-hash flag do?

@davilizh made improvements to the CUDA kernel hashing process and added this flag to allow changing the number of tasks it runs in parallel. These improvements were optimised for GTX 1060 GPUs which saw a large increase in hashrate, GTX 1070 and GTX 1080/Ti GPUs saw some, but less, improvement. The default value is 4 (which does not need to be set with the flag) and in most cases this will provide the best performance.

What is ethminer’s relationship with Genoil’s fork?

Genoil’s fork was the original source of this version, but as Genoil is no longer consistently maintaining that fork it became almost impossible for developers to get new code merged there. In the interests of progressing development without waiting for reviews this fork should be considered the active one and Genoil’s as legacy code.

No, use geth, the go program made for ethereum by ethereum.

CUDA GPU order changes sometimes. What can I do?

There is an environment var CUDA_DEVICE_ORDER which tells the Nvidia CUDA driver how to enumerates the graphic cards. The following values are valid:

FASTEST_FIRST (Default) — causes CUDA to guess which device is fastest using a simple heuristic.
PCI_BUS_ID — orders devices by PCI bus ID in ascending order.

To prevent some unwanted changes in the order of your CUDA devices you might set the environment variable to PCI_BUS_ID . This can be done with one of the 2 ways:

Adapt the /etc/environment file and add a line CUDA_DEVICE_ORDER=PCI_BUS_ID
Adapt your start script launching ethminer and add a line export CUDA_DEVICE_ORDER=PCI_BUS_ID

Adapt your environment using the control panel (just search setting environment windows control panel using your favorite search engine)
Adapt your start (.bat) file launching ethminer and add a line set CUDA_DEVICE_ORDER=PCI_BUS_ID or setx CUDA_DEVICE_ORDER PCI_BUS_ID . For more info about set see here, for more info about setx see here

Insufficient CUDA driver

You have to upgrade your Nvidia drivers. On Linux, install nvidia-396 package or newer.

A lot of unused and unnecessary code remove, what left was simplified in many places.
The build experience improved. The dependencies management migrated to Hunter C++ package manager. No system libraries are needed expect CUDA SDK if you want to build ethminer with CUDA support.
But you don’t have to build from source any more. The Continues Integration and Deployment systems have been configured to auto-deliver binaries for Linux, Windows and macOS.
CPU mining fully removed, including on-disk DAG generation support.
