ethminer – image28

  • Removed build systems and git submodules
  • Changed two lines of code so recent version of boost can be used
  • Removed cuda support for now
  • Plan to remove more as I go, eventually there will only be 4-5 remaining from the original code
  • Strpped binary comes out as 2.8mb on my system
  • Still early in testing but nicehash data reporting a 16mh/s improvement ( 1x amd 5500xt + 1x nvidia 1060gtx )

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.

Features

  • 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)

Install

Linux only maybe MacOS(Unix) – Requires system libs libboost, opencl, libjansson, ..?

git clone https://github.com/image28/ethminer.git ethminer-1mg28 cd ethminer-1mg28 cd build ./compile.sh # Cross fingers and hope it works for you

Usage

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:

ethminer --help

F.A.Q

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.

Can I CPU Mine?

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:

  • Linux:

    • 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
  • Windows:

    • 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

Error: Insufficient CUDA driver: 9010 

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

    随着DAG大小的增加,AMD卡是否也会受到速度减慢的影响?

    根据GNU通用公共许可证第3版获得许可。

    windows10上的新WDDM 2.x驱动程序使用不同的方式寻址GPU。这对很多事情都有好处,但对采矿没有好处。

    因为GDDR5X内存不能完全用于ETH挖掘。

    我还可以用我的4GB GPU来维护我的ETH吗?

    仅GCN 1.0 GPU(78×0、79×0、270、280),但方式不同。您将看到,在每个新纪元(30K块)上,哈希速率都会下降一点。

    最佳发射参数是什么?

    –cuda parallel hash标志做什么?

    不一定,您的VRAM必须大于DAG大小(目前约为4.023 GB)才能获得最佳性能。否则会发生严重的散列丢失。

    • 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.

    埃斯敏尔和基诺伊尔的叉子是什么关系?我能用我的CPU吗?

    在大多数场景(CUDA)中,默认参数很好。对于OpenCL,它的变化更大一些。只是玩玩数字和使用2的幂。GPU就像2的幂。

    CUDA GPU顺序有时会更改。我能做什么?

    @davilizh对CUDA内核散列过程进行了改进,并添加了此标志以允许更改并行运行的任务数。GTX 1060 GPU的哈希速率有了很大的提高,GTX 1070和GTX 1080/Ti GPU有了一些改进,但改进较少。默认值是4(不需要设置标志),在大多数情况下,这将提供最佳性能。

    CUDA驱动程序不足

    Genoil的fork是这个版本的原始源代码,但是由于Genoil不再持续维护这个fork,开发人员几乎不可能在那里合并新代码。为了在不等待审查的情况下进行开发,这个fork应该被视为活动的fork,而Genoil则被视为遗留代码。

    What are the optimal launch parameters?

    不,使用geth,以太坊eth以太坊eth制作的go程序。

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

    有一个environment var CUDA_DEVICE_ORDER,它告诉Nvidia CUDA驱动程序如何枚举图形卡。以下值是有效的:

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

    为了防止对CUDA设备的顺序进行一些不必要的更改,您可以将环境变量设置为PCI总线ID。这可以通过以下两种方法之一完成:

    Can I CPU Mine?

    Linux:

    CUDA GPU order changes sometimes. What can I do?

    Windows:

    • 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.

    您必须升级Nvidia驱动程序。在Linux上,安装nvidia-396软件包或更新版本。

    • Linux:

      • 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
