This guide assumes you are using a modern Windows OS with an . NVIDIA cards were historically less efficient at Scrypt and may require specific "CUDAminer" forks.

The lookup gap controls the memory trade-offs within the Scrypt algorithm. It can be configured between 0 and 2 . Setting this value to 2 cuts the memory footprint of Scrypt in half, allowing you to use much higher Thread Concurrency values without running out of VRAM. Execution and Command-Line Arguments
: Version 13.12 is highly recommended for maximum stability and hash rates. This guide assumes you are using a modern Windows OS with an

This is almost always caused by an unstable overclock or insufficient power supply voltage. Drop your memory clock down by 50MHz increments, lower the intensity by 1 point, or raise the power limit ( gpu-powertune ) within safe structural boundaries. High Hardware Errors (HW)
Because 3.7.2 is abandoned, the community created several "Spiritual Successors." It can be configured between 0 and 2

CGMiner runs best via a startup batch file ( .bat for Windows) or script ( .sh for Linux). Inside your CGMiner directory, create a new text file named start_mining.bat . Advanced Scrypt Configuration Tuning This public link is valid for 7 days
Therefore, capable of mining Scrypt coins like Litecoin using AMD graphics cards. If you find a download labeled "CGMiner 4.0+" claiming to support GPU Scrypt mining, it is likely a modified fork or malicious software. System Requirements and Prerequisites
: Higher intensity increases hashrate but can make your computer lag or cause "Hardware Errors" (HW) if set too high.
If this is wrong, you will get very low hashrates or errors.
