Updated cpuminer-multi 1.2-dev Windows Binary

4, Sep 2015

cpuminer-multi-1-2-dev-tpruvot

It has been a while since there has been an official release of the cpuminer-multi fork from tpruvot though he is working on his cpuminer-multi CPU miner with multiple algorithms support (source). This is the most functional fork of cpuminer that comes with support for the largest number of algorithms and a lot of optimizations for them to get the most performance out of your CPU. Do note however that some dedicated forks of cpuminer for a specific algorithm may still provide better performance, but if you want flexible solution with many algorithms supported then cpuminer-multi is the choice. We have compiled an up to date Windows binary from the latest source that comes with a lot of fixes and improvements regarding Lyra2RE and the new Lyra2REv2 algorithms as well as some other changes and extra functionality. If you have some spare CPU power that you want to use for mining then this is the miner you’ll need, do note that we have compiled our Windows binary with Visual Studio 2013 and for 64-bit Windows.

Updated Windows Binary of the ccMiner 1.5.63-git Fork by SP for Maxwell

2, Sep 2015

ccminer-1-5-63-sp-mod

A new update in the form of a new Windows binary release compiled from the latest Git source code of the ccMiner 1.5.63-git SP-MOD fork of the Nvidia GPU miner optimized for the latest Maxwell-based video cards by SP (source). The latest version includes more fixes and some slight hashrate improvements. Do note that the SP-MOD fork of ccMiner is designed for Nvidia Maxwell GPUs such as the already available GTX 750, 750 Ti as well as the newer GTX 960, GTX 970, GTX 980 and GTX 980 Ti and GTX Titan X. The Windows binary release we have made available here is with support for Compute 5.0 and Compute 5.2 GPUs or with other words only for Maxwell-based cards compiled with CUDA 6.5 and VS2013.

Update: We have compiled and updated the binary with the latest code changes that include significant increase in performance for BlakeCoin – up to about 70% increase in the hashrate. As an example with GTX 980 Ti the older ccMiner could get up about 2.033 GHS and with the updated version the performance we get now form the same GPU is 3.531 GHS, a GTX 950 GPU is up from about 677 MHS to 1.17 GHS, so the increase is very significant. Due to the high difficulty that BlakeCoin (BLC) has because of it being merge mined with multiple other coins this performance increase might actually make it interesting to actually mine it with Nvidia GPUs.

Updated Ethminer 0.9.41 OpenCL and CUDA for Windows

ethereumpool-statistics-hashrate

Since Ethereumpool has updated their Ethereum mining pool in a way that it requires the use of the latest version 0.9.41 of ethminer and we’ve got requests to post the latest version, we have prepared a package including ethminer 0.9.41 CUDA by Genoil (source) as well as the official ethminer 0.9.41 from the master branch (source) for Windows (64-bit is required!).

Do note that the CUDA version of the miner does support OpenCL mining as well and not only CUDA on Nvidia cards, the OpenCL support should function on both Nvidia and AMD GPUs. The ethminer 0.9.41 CUDA version is based on the new CUDA OpenCL PTX branch that requires at least Compute 3.5 capabilities from your Nvidia-based video card, so it may not work on older video cards. If you are having trouble running the new CUDA miner in CUDA mode on older Nvidia GPU you can revert to an older version or try using ethminer in OpenCL mode. Additionally to get better performance you can try adding the following command line parameters to the ethminer OpenCL and CUDA version:

For OpenCL: --cl-global-work 16384
For CUDA: --cuda-grid-size 8192 --cuda-block-size 128 --cuda-turbo

We have tested the two versions of ethminer version 0.9.41 and they both seem to work well as well as to report the actual hashrate you get when mining using the Ethereumpool mining pool regardless of what hashrate (difficulty) you set via the command line for running the miner software.
