cgminer
From lurkmore wiki
cgminer is cryptocoin mining software developed by Con Kolivas. It is the recommended software for mining cryptocoins such as Bitcoin and Litecoin.
Version 3.7.2 is the last version of cgminer to support GPU or scrypt mining.
For scrypt and GPU mining, the recommended version of cgminer is 3.1.1. For the newer Rx series video cards, 3.7.2 might work better. For older video cards, version 3.1.1 has no scrypt or GPU mining bugs, and there are no important changes between that version and the later ones. Newer cards might need version 3.7.2 in order to work more effectively (or at all) with the latest SDK (that come with the drivers).
