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/drivers.
Devices not found error
This is an error usually found on Linux systems. The error may be cause by many reasons (including failed hardware) but one of the main reasons is the addition of a new video card without reinitializing the configuration files. To do so, run aticonfig --adapter=all --initialize and reboot. This command may not work the first time, to resolve this, delete the current file (/etc/X11/xorg.conf on Debian) and run the command again.
Not enough memory, change your TC
Errors about not having enough memory and needing to change your TC are usually found in Windows and can be resolved by running setx GPU_MAX_ALLOC_PERCENT 100 in the Windows command prompt (winkey+r > cmd). The same issue might appear in Linux if export GPU_MAX_ALLOC_PERCENT=100 wasn't added to /etc/profile (Debian, again)
