NVCurve is a newly developed voltage-frequency curve editor designed for Nvidia GPUs operating on Linux, offering users the ability to automate undervolting. Unlike traditional tools, NVCurve does not provide a one-click undervolt option but allows for precise adjustments along the GPU's voltage-frequency curve. The primary interface is a web UI that facilitates real-time monitoring and interactive curve editing. For users preferring command-line interfaces, a Python CLI is available, enabling headless operation and automation through JSON configuration. While NVCurve shows promise, it is experimental and relies on undocumented Nvidia APIs, which could lead to potential issues with future driver updates. Alternatives such as LACT and GreenWithEnvy provide broader support for GPU tuning but lack the specific V/F curve manipulation that NVCurve offers. Overall, NVCurve represents a significant advancement for Linux users seeking enhanced control over their Nvidia GPUs, making it a valuable tool despite its experimental nature.
