Cudaminer Guide for Nvidia GPUs

CUDA Core is the term Nvidia uses to call the shaders in its GPUs. The Cudaminer is designed specifically for Nvidia GPU mining with Cuda accelerated mining application for
Litecoin and Scrypt based altcoins. There would be a noticeable speed increase compared to OpenCL based miners.

Cudaminer

1. Download

•    Cudaminer-2013-12-18.zip (version as at 19 Jan 2014)
•    or look for the latest version from the official link.

2. Check your GPU
•    Before going into the configuration, you would want to know which GPU that you have, so that you will find out the compute version that it is using. If you are not sure, you can install GPU-Z to find out.
•    Also make sure that you have the latest drivers installed for your Nvidia GPU. You can check this out at Nvidia’s download section.

3. Compute version

From your Nvidia GPU model, identify the compute version that the card is using, so that you would know which kernel prefix is suitable.

CUDA kernels do the computation. Which one we select and in which configuration it is run greatly affects performance. CUDA kernel launch configurations are given as a character string, e.g. F16x2
prefix blocks x warps
Available kernel prefixes are:
•    L – Legacy cards (Compute 1.x)
•    F – Fermi cards (Compute 2.x)
•    S – Kepler cards (currently compiled for Compute 1.2) – formerly best for Kepler
•    K – Kepler cards (Compute 3.0) – based on Dave Andersen’s work. Now best for Kepler.
•    T – Titan, GTX 780 and GK208 based cards (Compute 3.5)
•    X – Experimental kernel. Currently requires Compute 3.5

Examples:

•    L27x3 is a launch configuration that works well on GTX 260
•    F28x4 is a launch configuration that works on Geforce GTX 460
•    K290x2 is a launch configuration that works on Geforce GTX 660Ti
•    T30x16 is a launch configuration that works on GTX 780Ti.

4. Cudaminer configuration

Most of the time you can start mining without specifying any special options and let autotune select the best option for you like this:
cudaminer -o stratum+tcp://coinotron.com:3334 -O [WORKERNAME]:[PASSWORD]

I will list the configuration for some Nvidia cards:
•    GeForce GTX 560 Ti
cudaminer -H 0 -i 1 -l F8x16 -C 1 -m 1 -o stratum+tcp://coinotron.com:3334 -O [WORKERNAME]:[PASSWORD]
•    GeForce GTX 660
cudaminer -H 0 -i 1 -l K5x32 -C 1 -m 1 -o stratum+tcp://coinotron.com:3334 -O [WORKERNAME]:[PASSWORD]
•    GeForce GTX 670
cudaminer -H 0 -i 1 -l K7x32 -C 1 -m 1 -o stratum+tcp://coinotron.com:3334 -O [WORKERNAME]:[PASSWORD]
•    GeForce GTX 780
cudaminer -H 1 -i 1 -l T9x20 -C 2 or -H 1 -i 1 -l T12x32 -c 1 -o stratum+tcp://coinotron.com:3334 -O [WORKERNAME]:[PASSWORD]

Check out the latest update of cudaMiner with support for Maxwell architecture. This will be the biggest performance change on mining with Nvidia cards.
