Ethminer 0.9.41-genoil-1.0.8: Download Ethereum miner for Windows/Linux

Genoil has updated its fork of ethminer 0.9.41 to version 1.0.8 (source), and here is the latest Windows binary file that you can try. The fork of Genoil ethminer is for Nvidia CUDA miners, but it also runs on AMD OpenCL for Ethereum mining (ETH). Some minor bugs have been fixed and improved in the new version 1.0.8, but probably the most important new feature is the significantly improved output that you get, more user-friendly with a single line of text reporting your current status. You can download and try the compiled binary of the latest version 1.0.8 and make sure that you also take advantage of the recently introduced Stratum failover function. Check the sample .bat file for more information on how to use the new Stratum failover mode, and check the new output from the shorter hash log, the accepted and rejected shared resources by the pools, and the errors.

What is ethminer-0.9.41-genoil-1.x.x?

Formerly known as Genoil’s CUDA miner, ethminer-0.9.41-genoil-1.x.x is a fork of the stock ethminer version 0.9.41. While native CUDA support is its most significant difference, it has the following additional features:

realistic benchmarking against arbitrary epoch/DAG/blocknumber
custom DAG storage directory
auto DAG directory cleanup
stratum mining without proxy
OpenCL devices picking
farm failover (getwork + stratum)

Usage

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

ethminer --help

F.A.Q

Why is my hashrate with Nvidia cards on Windows 10 so low? The new WDDM 2.0 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. 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.
And what about the GTX750Ti? Unfortunately the issue is a bit more serious on the GTX750Ti, already causing suboptimal performance on Win7 and Linux. Apparently about 5MH/s can still be reached on Linux, which, depending on ETH price, could still be profitable, considering the relatively low power draw.
Are AMD cards also affected by this issue? Yes, but in a different way. While Nvidia cards have thresholds (i.e 2GB for 9×0 / Win7) of the DAG file size after which performance will drop steeply, on AMD cards the hashrate also drops with increasing DAG size, but more in a linear pattern.
Can I still mine ETH with my 2GB GPU? 2GB should be sufficient for a while, altough it’s become a bit uncertain if we’ll stay below 2GB until the switch to PoS. I don’t keep an exact list of all supported GPU’s, but generally speaking the following cards should be ok: AMD HD78xx, HD79xx, R9 2xx, R9 3xx, Fury. Nvidia Geforce 6×0, 7×0, 8×0, 9×0, TITAN Quadro, Tesla & FirePro’s with similar silicon should be fine too.
Can I buy a private kernel from you that hashes faster? No.
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.
Is your miner faster than the stock miner? In CUDA yes, in OpenCL only on Nvidia .

Building on Windows

download or clone this repository
download and install Visual Studio 12 2013 and CMake
run getstuff.bat in cpp-ethereum/extdep
open a command prompt and navigate to cpp-ethereum directory

mkdir build 
cd build
cmake -DBUNDLE=cudaminer -G "Visual Studio 12 2013 Win64" ..

if you don’t want/need CUDA support, use “miner” instead of “cudaminer”. This will only compile OpenCL support
to speed up compilation a bit, you can add -DCOMPUTE=xx , where x is your CUDA GPU Compute version * 10. i.e -DCOMPUTE=52 for a GTX970.
you may disable stratum support by adding -DETH_STRATUM=0
When CMake completes without errors, opn ethereum.sln created in the build directory in Visual Studio
Set “ethminer” as startup project by right-clicking on it in the project pane
Build. Run
