: If the "HW" count in the CGMiner interface is anything other than 0, your settings are too aggressive. Lower your intensity or clock speeds. 5. Staying Safe
| Software | GPU Scrypt Support | Hashrate vs CGMiner 3.7.2 | Ease of Use | | :--- | :--- | :--- | :--- | | | Yes (legacy AMD only) | Baseline (100%) | Very Hard | | Sgminer 5.x | Yes (better modern GPU support) | 110-120% | Hard | | Awesome Miner | Yes (via sgminer kernel) | 105% | Easy | | NiceHash QuickMiner | No (Scrypt not supported) | N/A | Very Easy |
Scrypt was designed as a "memory-hard" algorithm to resist ASIC specialization, requiring high system and GPU RAM to function effectively. CGMiner 3.7.2 serves as a multi-threaded, command-line tool written in C that manages these hardware resources through OpenCL. Core Mining Parameters cgminer/SCRYPT-README at 3.7 - GitHub
