It Is All About BTC, LTC, ETH, DOGE, KAS mining as well as other alternative crypto currencies
NiceHash has forked SP’s ccMiner 1.5.80 GPU miner for Nvidia Maxwell GPUs (source) and has added significantly improved support for the Lyra2REv2 algorithm that can apparently provide up to 100% increase in terms of performance. SO if you are mining a crypto currency that uses the Lyra2REv2 algorithm or are selling your hashrate on Nicehash, then you might want to go for the new miner. We have compiled a 32-bit Windows binary, using VS2013 with CUDA 7.5 that you can download and try. Do note that it is compiled only for Nvidia Maxwell GPUs supporting Compute 5.0 and Compute 5.2 such as GTX 750, 750 Ti, GTX 950 GTX 960, GTX 970, GTX 980, GTX 980 Ti and GTX Titan X.
When talking about GPU mining with Nvidia-based GPUS for crypto currencies there are two models that usually come in mind – the GeForce GTX 750 Ti and GTX 970. When talking about Ethereum mining however Nvidia mining rigs do not do that well compared to AMD-based rigs and while the GTX 970 does pretty well at about 20-21 MHS the GTX 750 Ti is performing terribly, so it is not suitable for ETH mining. A good choice for GPUs that have only 1 GB of video memory or do not perform well for mining Ethereum is to go for mining Decred (DCR) at the moment, so you have good alternative. But if you are currently building a low powered multi-GPU mining rig at the moment with Nvidia-based GPUs the card of choise will most likely not be the 750 Ti anymore, you should go for the slightly more expensive GTX 950.
The GTX 950 is doing much better for mining Ethereum as compared to GTX 750 Ti, you can expect to see somewhere around 10 MHS from the 950 and it has been like that since the beginning (no performance drop like on some AMD cards). The reference design GTX 950 has a TDP of 90W as compared to 60W for the reference design GTX 750 Ti, but it also offers higher performance and is usable for Ethereum mining at 10 MHS. So a 6 GPU mining rig using Nvidia GeForce GTX 950 video cards should come at about 600W of total power consumption at max load and giving you about 62 MHS hashrate for mining Ethereum (Ethereum does not use the most power hungry algorithm). The GTX 950 does pretty well for other mining algorithms as well, you have alternatives available like DCR and will still get good performance and profit. Here is a comparison between GTX 750 Ti doing around 500 MHS with the latest ccMiner fork from tpruvot with Decred support (the faster 64-bit version) versus around 645 MHS for GTX 950, these numbers are from the publicly available miner. So do consider going for GTX 950 instead of GTX 750 Ti if you are building an Nvidia mining rig now and GTX 970+ is not an option at the moment.
A few days ago we have posted a windows binary compiled from the latest source of ccMiner 1.7-git from tpruvot and now the official 1.7 release is available with a windows binary compiled by the author of the miner. The final version does come with some additional fixes and improvements as compared to the 1.7-git release from a few days ago, so if you are using the older windows binary you might want to update now. The ccMiner 1.7-tpruvot fork brings support for old Compute 2.0 (SM 2.1) devices for many of the crypto algorithms allowing users with older Nvidia GPUs to use them to mine. It also brings some performance improvements for newer Compute 5.0+ GPUs and adds new features such as automatic benchmark mode for all supported algorithms and some other interesting new features. The ccMiner 1.7-tpruvot fork supports Nvidia-based GPUs with Compute 2.0 or newer capabilities, so make sure that you are not trying to run the miner on too old hardware. The official x86 Windows binary release is for older SM 2.1+ devices while the x64-bit one is intended for newer SM 3.5+ devices.
