The guys at NiceHash have released a beta version of their own easy-to-use best-profit auto-switching application called NiceHash Miner. The software detects what crypto mining capable hardware you have in your systems (for now supports only Nvidia GPUs and CPU mining), checks your hashrate and automatically switches to the most profitable algorithm available to give you the best profit for your hashrate. All you have to do is download and run the miner, choose the server location and enter your Bitcoin wallet address where you want to get your coins sent at and you are almost ready to start mining and maximizing your profit. As a backend the NiceHash Miner relies on the cpuminer-multi form tpruvot for CPU mining and to the ccminer forks from tpruvot and sp for the Nvidia GPU mining.


The first time you run the NiceHash Miner software you will need to go through the Benchmark mode in order for the software to determine what your mining hashrate will provide in terms of hashrate for the different supported algorithm. Then you are ready to start mining with all or only a few of the mining capable CPUs/GPUs you have available – you can choose what you want to mine with. There is however still no support for you to chose only some of the supported algorithm, so you are stuck with all of the available in the software. We are probably soon also going to see an OpenCL miner such as sgminer integrated to add support for AMD GPUs as well, but for now if you have AMD GPUs you can still rely on the Miner Control Tool for example for automatic profit switching at NiceHash/Westhash. Their own tool does look promising and works pretty well, but it needs more work and features, also do not forget that it is still in beta. Still you might want to give it a try though…

Ethpool was the first mining pool for mining Ethereum’s Ether coins, however it had some issues, was down for a while and then returned with a new concept – predictable solo mining pool. A predictable solo mining pool allows you to do pooled mining with a solo mining payment scheme, meaning that the miner who contributed the most work to the pool for each round will receive the full reward of the found block (or uncle) and his work account (credits) will be reset to his current credits minus the credits of the runner up miner. This simply means that depending on your available hashrate it may take more time to get your reward, but once you get it it will be a full block reward. Apparently the downtime and the new concept along with the low exchange rate for Ethereum’s Ether coins lately are not doing Ethpool much good, but they have not stopped working on new things.

The latest addition is stratum support instead of the getwork that is typically used by the regular ethminer software. The introduction of stratum support requires users to use a special fork of ethminer that is called qtminer (source) that has been developed by Ethpool and is ONLY supported by their mining pool for the moment. A while ago another pool – Dwarfpool, has introduced a Stratum proxy as we’ve mentioned earlier on the blog, but their proxy implementation is not as good as actually having a dedicated stratum protocol supported by the miner itself.

The command line of qtminer is very similar to that of Ethminer, you can check the HELP.txt file included in the Windows binary available for download below for the supported commands. As with ethminer, qtminer supports OpenCL mining on both AMD and Nvidia GPUs, there is no CUDA support available for Nvidia for the moment, and you should not be getting much different performance in terms of hashrate between ethminer and qtminer (AMD video cards still perform better than Nvidia ones). The actual difference is in the protocol used to get shares and submit them which should result in improved performance when you are using stratum instead of getwork due to better efficiency of the stratum communication protocol. Do note that you can still use Ethpool with ethminer and the getwork protocol if you are not satisfied with the results you get from the new qtminer with stratum support.

The new qtminer stratum pool supports vardiff, so the difficulty will be automatically adjusted by the pool itself based on the hashrate you submit thus taking the guesswork and the need to find the optimal difficulty yourself. The result should be more efficient getting of new work and submitting of solved shares using constant stratum connection to the server and thus more mined coins for the same period of time as compared to using ethminer with getwork polling the server all the time. Looking at the logs of the qtminer and testing briefly the new stratum miner is showing that it works better than ethminer, make sure you allow a bit of time to get a good estimate on the current hashrate reported by the pool and estimated earning before drawing any conclusions. You should definitely give qtminer a try if you are currently mining for Ethereum’s (ETH) Ether coins on a pool with the traditional etminer, you might be pleasantly surprised by the improvement.

One more update in the form of a Windows binary release compiled from the latest Git source code of the ccMiner 1.5.71-git SP-MOD fork by SP optimized for the latest Maxwell-based video cards (source) to bring things up to date. The latest release comes with tiny speedups in lyra2v2 and quark, support for the whirlpool algorithm brought back and some fixes for the myriad-groestl that was apparently not working properly in the previous releases. 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 Nvidia video cards compiled with CUDA 6.5 and VS2013.
