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)
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

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 9x0 / 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 6x0, 7x0, 8x0, 9x0, 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 .
- 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
