If you want to mine GPU Coin with Nvidia GPUs you will need to use the cudaminer software miner. GPUC uses Scrypt-Adaptive-Nfactor and not the standard Scrypt algorithm, so you need to run cudaminer with the –algo=scrypt:2048 parameter and not just with –algo=scrypt. Do have in mind that you should see about half of the typical Scrypt hashrate you get when you start mining for GPU Coin and that is absolutely normal due to the different algorithm being used.

We have tested mining for GPU Coin with a GeForce GTX 750 Ti video card running at stock frequencies and got about 134 KHS hashrate, after overclocking we’ve managed to get up to about 146 KHS. The kernel configuration that we found to work best was T10x24 on the GTX 750 Ti and this is the command line parameters we’ve used to launch the miner:

cudaminer.exe --algo=scrypt:2048 -o stratum+tcp://east1.us.stratum.dedicatedpool.com:3367 -u yourworker.1 -p password -i 0 -l T10x20 -C 1 -H 2

Below you can download the latest version of cudaminer 2014-02-28 for Windows with BAT files ready with the settings for mining GPU Coin, so you just need to configure them with your pool settings and start mining. Note that the default settings are the best for mining with GTX 750 Ti graphics cards, so you might need to change the kernel to another one based on your GPU or just remove the line setting up the kernel to use the autotune feature.
