All About BTC, LTC, ETH mining as well as other alternative crypto currencies
There is now a new ccMiner fork with support for the X15 algorithm available for Nvidia GPU miners thanks to djm34 (source). The X15 algorithm support is still a bit rough, but it works quite well already, so you can experiment with it and try mining with your GPUs. We have tried it on a GeForce GTX 750 Ti where we are getting about 1450 KHS hashrate when mining for a X15 crypto coin such as BitBlock, and from a GeForce GTX 780 Ti you can expect to get around 2600 KHS in terms of hashrate with this new miner.
We have compiled a windows binary of the new miner and you can download it from the link below. Do note however that the windows binary is compiled for Compute 3.0, 3.5 and 5.0 cards (32-bit version only) in a single binary, so it will not work on older cards. If you are unsure what version of Compute does your video card support check the included GPU Compute Capabilities List file. It is also compiled with Visual Studio 2012, so if you do not already have Visual C++ Redistributable for Visual Studio 2012 you will have to download and install it, otherwise you may be getting error for a missing DLL library.
