Here are configuration examples used by miners for various AMD cards:
: Version 3.7.2 is the final "full version" to include the Scrypt mining kernel optimized for AMD/ATI GPUs. Highly Customizable
Double-click your batch file. If you see a green display of (5s): 0.000 followed by a hashrate, you are mining Litecoin. If you see No devices found or CL_DEVICE_NOT_FOUND , your OpenCL drivers are incorrect.
Here is a comprehensive guide to understanding, setting up, and using CGMiner 3.7.2. Here are configuration examples used by miners for
cgminer.exe --scrypt -o stratum+tcp://pool-address:port -u username.worker -p password --gpu-engine 950 --gpu-memclock 825 --auto-fan --temp-target 75 Use code with caution. : Tells CGMiner to use the Scrypt algorithm. -o : Pool URL. -u : Your worker username. -p : Worker password.
CGMiner 3.7.2 is the definitive, stable solution for those looking to mine Scrypt-based coins with AMD GPUs. Its comprehensive "full version" update provides everything from fine-grained GPU control to robust pool management, making it the superior choice for legacy Scrypt hardware.
: Controls the workload sent to the GPU. For Scrypt, this ranges between 13 and 20. High intensity increases hash rate but makes the system laggy. If you see No devices found or CL_DEVICE_NOT_FOUND
Here is an example configuration for CGMiner 3.7.2:
Putting old AMD Radeon HD 7950s or R9 280Xs to work for experimental purposes. Safety Warning: The "Full Version UPD" Trap
: It allows direct hardware manipulation of clock speeds, voltages, and fan profiles. : Tells CGMiner to use the Scrypt algorithm
: Monitor your hash rates, accepted shares, and hardware health (temperature/voltage) in real-time. Setting Up Your Mining Script (.bat)
This guide has provided you with the knowledge to find, install, configure, and troubleshoot CGminer 3.7.2. From setting vital environment variables to fine-tuning intensities and thread concurrencies, you now have the tools to get the most out of this powerful yet archaic software.
A typical Windows batch file ( mine_litecoin.bat ) for an AMD Radeon rig in 2014 looked like this:
Built-in tools to adjust clock speeds and voltages without third-party software.
: Controls how much of your GPU's power is dedicated to mining. Higher numbers increase hash rate but can make your PC laggy. --thread-concurrency
