Tpruvot has made an official release of his updated ccMiner fork (source) version 1.8.1 along with Windows x86 and x64 binaries available for download. The x86 Windows binary is compiled with VS2013 and CUDA 8.0 RC and the x64 binary is compiled with CUDA 7.5, it is best to use the latest video drivers to have support for CUDA 8.0.

The new ccMiner 1.8.1 adds support for mining Siacoin (SC) on Nvidia GPUs using CUDA, SIA uses Blake2-B algorithm, though at the moment different pools still seem to rely on different protocols for mining and not all of them are yet supported by ccMiner. The miner supports the SIA Nanopool RPC (getwork over http) as well as the getwork over Stratum implementation of Suprnova, but not yet the Siaminingpool stratum protocol (you should still be able to mine there via getwork). The hashrate seems to be slightly better than that Sia Go Miner that uses OpenCL and also works on Nvidia GPUs.

The new version 1.8.1 also comes with small improvement in the LBRY hashrate improvements (by alexis78) over the previous release 1.8 that introduced Library Credits mining. So if you are mining LBC with Nvidia GPUs, then you might wan to update to the new release in order to get slightly better hashrate. The Lyra2RE support has also been updated with the with the Nanashi Meiyo-Meijin improvements, so it should be faster than before.

Sia CUDA Miner is a GPU miner designed for mining Siacoins on Nvidia GPUs using CUDA instead of OpenCL like on the Siacoin Go pool miner. The Sia CUDA Miner is being developed by KlausT (source) and works pretty well already, though it still needs some more work in terms of available features and in terms of performance optimizations. Our tests have shown that using the Sia CUDA Miner on various Nvidia GPUs does result in a hashrate that is a bit lower than what you can get using the OpenCL miner on the same hardware. Another limitation that the CUDA miner has is that by default it runs on a single GPU and you will need multiple instances running to have it work on multiple GPUs. Also, although the miner supports pool mining it apparently only works with pools that have long pooling enabled and this means that for the moment you are limited to the Siamining pool.

We have compiled a 64-bit Windows binary using CUDA 8.0 available for download below, our tests have shown that this was the fastest performing versions after trying different versions of CUDA and 32-bit compilation. The Windows binary is based on the latest source code and is version 4.01 that should provide more stable and problem free pool mining as compared to earlier releases. You are welcome to try the miner and report your results, but as we’ve already said the OpenCL miner is still the better choice for Nvidia GPUs at the moment in terms of features and support as well as performance wise in terms of hashrate, so you might want to stick to the Sia Go Pool miner that uses OpenCL.
