Genoil, the developer of the Ethminer fork with Nvidia CUDA support (source) has been actively working and there have been some other people contributing code, so we have compiled an up to date Windows binary of ethminer with CUDA support. Do note that this Windows binary release is compiled with VS2013 for Windows 64-bit and is for CUDA 6.5 as previous versions were compiled for CUDA 7.5, so there could be some performance differences between the different versions. The latest version comes with some optimizations that should increase a bit the performance when using the CUDA mode with the miner, however there are also some differences as you may need to manually specify the number of GPUs to use if you have multiple cards using the cuda-devices command line parameter if the miner fires only on one device. Additionally to get better performance you can try adding the following command line parameters to the ethminer:
For OpenCL:
--cl-global-work 16384
For CUDA:--cuda-grid-size 8192 --cuda-block-size 128 --cuda-turbo
The Ethminer CUDA fork should work on Compute 2.0 or newer GPUs, but the performance on older GPUs can be worse, also don’t forget that you can run Ethminer in OpenCL mode as well on Nvidia-based video cards and not only on AMD if you are having trouble with the CUDA support or the hashrate you get is lower as compared to OpenCL.

Updated Ethereum Ethminer with Nvidia CUDA Support
19, Aug 2015
Genoil, the developer of the Ethminer fork with Nvidia CUDA support (source) has implemented some updates to the code of the project contributed by SP and tpruvot that reduce the load on the CPU when the miner is running. Also the default worksize has been increased form 64 to 128, but other than that there should be no changes affecting the performance of the miner. The reduction of CPU usage may come at the cost of slight hashrate drop, but there is a command line parameter now that you can use to stick with the higher CPU load and get the slightly higher performance --high-cpu-load, so it is up to you to decide. We have updated our package with Geth and Ethminer for OpenCL and CUDA with the latest version of the Ethminer CUDA binary for Windows (requires 64-bit Windows), so you can download and try it. The Ethminer CUDA fork should work on Compute 2.0 or newer GPUs, we have tested it with a Compute 2.1 and it is working fine, but don’t forget that you can run Ethminer in OpenCL mode as well on Nvidia-based video cards and not only on AMD if you are having trouble with the CUDA support or the hashrate you get is lower as compared to OpenCL.

Time for another update of the complete packages based on the Miner Control tool for Nvidia GeForce GT 750 Ti and AMD Radon R9 280x GPUs due to the latest developments in the mining world. The latest versions you can download from the links below include some updates and it removes the YAAMP pool support as it has become a part of NiceHashand currently redirects to their stratum servers. The latest updates also includes the most recent versions of SP-MOD’s ccMiner for Nvidia Maxwell as well as the sgminer fork with increased performance for Quark and Qubit with pre-compiled Binary Kernels for 280X. The two Miner Control tool packages are based on the latest fork of Miner Control from KBomba version 1.6.4.
To be ready to use the packages you just need to update the account settings for each pool to reflect your BTC payment address. Do note that the default configuration that we have set is mining from time to time for the author of the software (Miner Control) as a donation alternative, but you can change that setting should you wish to. The packages are ready to be used with either AMD Radeon R9 280X or Nvidia Geforce GTX 750 Ti cards, but you can also us the Nvidia package for other GPUs or more cards – what you may need to reflect however in the config file is the total hashrate and power usage. Since the AMD packages contains not only specific settings for AMD Radeon R9 280X, but also pre-compiled binary kernels specifically for that particular card if using it with other GPUs you will actually be getting lower hashrate, though n problem to use it with multiple 280X cards.
