New Ethminer 0.9.41-genoil-1.1.2 pre-release Windows Binary

2, Jun 2016

ethminer-0-9-41-genoil-1-1-2-pre

Here comes a Windows binary for another pre-release of Genoil’s ethminer 0.9.41 fork version 1.1.2 (source) that should be used by people with the latest generation of Nvidia Pascal GPUs such as GTX 1080 and GTX 1070. The release is compiled with CUDA 8.0 and has support for Compute 6.1 that is used by the latest Nvidia GPUs, however it seems that the performance under Windows is currently significantly lower that you would expect on the GTX 1080/1070, so it is recommended to use Linux for the best performance on these video cards for now (similar to the situation with GTX 750 Ti). Regardless, you would be able to run this version of Nvidia Pascal GPUs for mining Ethereum, but at just about 1/4 – 1/5 of the performance you would be getting if using Linux with the same GPU. On Maxwell and other older architectures there should be no notable difference in terms of performance however with this Windows binary compared to previous releases. Other new addition is the support for simultaneous mining on both AMD and Nvidia GPUs installed in the same system (you need to use the option X instead of G or U), prior to that you could only run OpenCL or CUDA, but not on both at the same time. Do note that the new mixed X mode for CL/CUDA mining does not yet support separate settings for optimum performance for the different GPUs such as local and global work per GPU. Again, this is a pre-release version with the idea for people to try and report how the new features work and if they find any bugs, so you are welcome to try it…

Updated ccMiner 1.8-dev fork by tpruvot With X11 Evo Support

1, Jun 2016

ccminer-1-8-dev-tpruvot-x11evo

Here comes another interesting update of the ccMiner fork by tpruvot with a new Windows binary we have compiled from the latest ccMiner 1.8-dev (source) that comes with support for the new X11 Evo algorithm. The Windows binary is built from the Linux branch and is a 32-bit one compiled with CUDA 6.5 and with support for Compute 2.0 or newer Nvidia GPUs. Our quick test has shown pretty good performance from the ccMiner with X11 Evo support as compared to the sgminer fork for the X11 Evo algorithm supplied by the Revolvercoin (XRE) team, so Nvidia miners will have a serious advantage at the moment. While you can get about 2-3 MHS on a 280X 290X using the sgminer fork, with this release of ccMiner you can expect to see over 7 MHS on GTX 970 or over 10 MHS on a GTX 980 Ti, so significantly faster hashrate on Nvidia GPUs for the moment. So Nvidia miners might be interested in checking out the new Revolvercoin (XRE) altcoin as it is currently the only one that uses the X11 Evo algorithm and if you have some issue with X11evo support please report it…

Windows Binaries for the cpuminer-opt 3.3.4 CPU Miner

31, May 2016

cpuminer-opt-3-3-windows

The cpuminer-opt miner (source) is a fork from cpuminer-multi by tpruvot that adds optimizations for many algorithms for more recent CPUs with support for the AES-NI instruction set, though the miner also works on older SSE2 capable CPUs with lower performance. Up until recently the cpuminer-opt was available only for Linux users, but starting from version 3.3 there is also Windows support and we have compiled 64-bit binaries of the miner for Windows. In the archive below you can find multiple executable files that are compiled for different CPU architectures that support AES-NI instructions, so you are welcome to try them. The default cpuminer.exe is compiled for Intel Westmere, the first architecture that has support for the AES-NI instruction set and cpuminer-amd.exe is bdver1 which should work on all AMD processors with AES-NI. If you have a more recent Intel Sandybridge, Ivybridge, Haswell or Broadwell-based processor you can try the respective binary to see if that will squeeze some extra performance, or you can compile directly on your PC with the native instruction set supported by your CPU. We have not tried much of the algorithms of the miner yet, but we have checked HODL support – one of the more recent interesting CPU-only coins and it seems to be working well, though on some systems it occasionally gives low difficulty shares.

Update: We have updated the binaries to the latest version cpuminer-opt 3.3.4 that has support for the X11Evo algorithm used by Revolvercoin (XRE). The latest version should also fix the low difficulty shares for HODL that were present in the earlier releases and improve compatibility for some CPUs, including resolving issues that some people had with Intel Westmere-based processors. There is also a significant improvement for the performance of the M7M used by the Coin Magi (XMG) over the older versions of cpuminer-opt. We have also added cpuminer-sse2.exe binary for processors that do not have AES-NI support, so you might want to try that one if you have an older processor. Just download the archive below for the latest version of the binaries compiled for Windows.
