The Latest Ethminer 0.9.41-genoil-1.0.4b3 for Windows

24, Feb 2016

ethminer-benchmark-280x

Ethminer 0.9.41-genoil-1.0.4b3 (source) is the latest release of Genoil’s CUDA miner forked from the official ethminer that is designed to work on Nvidia CUDA GPUs, but will also work on AMD OpenCL GPUs as well. The latest version adds some useful features for both AMD and Nvidia miners, though there is not much of a difference in terms of performance compared to older releases, so do not expect to see faster hashrate. In fact the hashrate on AMD GPUs has been decreasing over time due to the increasing size od the DAG files used by the miner for mining Ethereum’s Ether (ETH) coins.

The latest release contains more advanced benchmark options that allow you to check how performance changed or will change in time, there is an option to set a custom DAG storage folder and even support for stratum mining without a proxy, although currently limited to support only for Coinotron with more pools to come. We ran a quick test to check how the hashrate changed over time between block 1 and block 1 million of Ethereum on an AMD Radeon R9 280X GPU and on Nvidia Geforce GTX 970 GPU. As you can see from the results below the performance has dropped quite a bit on AMD, but has not changed on Nvidia, do note however that Nvidia-based video cards are slower in terms of mining performance for Ethereum… at least for the moment.

GeForce GTX 970:
Block 1 – 17.31 MHS
Block 1M – 17.31 MHS

Radeon R9 280X:
Block 1 – 25.95 MHS
Block 1M – 21.49 MHS

Updated ccMiner 1.7.3 fork by tpruvot With Improved Decred Support

22, Feb 2016

ccminer-1-7-3-tpruvot-decred

A quick update with a new Windows binary compiled from the latest ccMiner 1.7.3-git fork from tpruvot (source) with some improvements regarding the Decred (DCR) that uses a bit different Blake256 14-round algorithm. This release supports Decred mining with both the traditional getwork implementation as well as the getwork over stratum support that yiimp and some other pools have already implemented. The release below includes two versions of ccMiner, one is 32-bit binary for Windows that is compiled with CUDA 6.5 and with support for Compute 2.0 or newer Nvidia GPUs, and another that is 64-bit Windows binary compiled with CUDA 7.5 for Compute 3.5 or newer Nvidia GPUs. Do note that if you have a newer Nvidia video card you should use the 64-bit CUDA 7.5 release as it is providing better hashrate than the 32-bit CUDA 6.5 binary. Below is a quick comparison of the performance of the two versions on a Gigabyte GeForce GTX 970 WF3OC GPU running at stock frequencies.

Decred (DCR) performance on GTX 970:
– 32-bit CUDA 6.5: 1189 MHS
– 64-bit CUDA 7.5: 1298 MHS

Updated ccMiner 1.7.2 fork by tpruvot With VanillaCoin and Decred Support

11, Feb 2016

ccminer-1-7-2-tpruvot

Version 1.7.2 of tpruvot’s ccMiner fork source) for GPU mining on Nvidia-based video cards has been released and it comes with official support for Vanillacoin (VNL) as well as Decred (DCR) support. Below you can find compiled Windows binaries to try out the mining them, both are Blake256-based, but with some different requirements such as the need to use longpoll and getwork, and no support for stratum for Decred for example. There are two versions available, the 32-bit one is with support for older Compute 2.1 and 3.0 GPUs while the 64-bit version is for the newer Compute 3.5, 5 and 5.2 cards. We have tested the new release on GTX 970 and the results are slightly better at about 1.35 GHS (with the 64-bit miner) than what we are getting with the cgminer fork for Decred that relies on OpenCL that is also compatible with Nvidia cards. The ccMiner fork might be helpful to people that are having very high CPU usage with cgminer that results in lower mining performance, though the CPU load is still not that low even with ccMiner. Also the use of ccMiner for mining Decred could result in less rejected shares from the pool and no weird errors as some people are experiencing with cgminer, so if you are mining DCR on Nvidia with cgminer, then you should try with ccMiner as well.
