nvuv review
A free, open-source Linux utility for scripted NVIDIA GPU tuning and startup settings.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
nvuv is a free, open-source command-line utility for tuning NVIDIA GPUs on Linux. It is aimed at users who want direct control over GPU and memory clock ranges, clock offsets, and power limits, particularly in multi-GPU systems. The tool can query GPU and performance-state information, select individual GPUs, validate TOML configuration files, and apply settings through a provided systemd service. Its focus is configuration-driven tuning rather than a graphical overclocking workspace.
The strongest fit is persistent automation. A systemd service can apply settings at startup and resume, while TOML validation and application provide a structured way to manage multiple GPU configurations. GPU clock-range locking, memory clock-range locking, positive clock offsets, and power-limit adjustment cover several core tuning operations. nvuv also uses NVIDIA’s NVML library and supports per-GPU selection, making it practical for Linux systems where repeatable command-line configuration matters more than visual controls.
Undervolting requires a specific expectation: nvuv provides indirect undervolting by locking GPU clock ranges and applying positive clock offsets, rather than direct voltage adjustment. NVIDIA does not expose direct voltage control on Linux, so the tool does not offer custom voltage control. It also lacks profiles, monitoring, and overlay controls, which limits its appeal for users seeking an all-in-one tuning interface. Choose nvuv for free, open-source, scriptable NVIDIA tuning on Linux with startup persistence; choose another tool if direct voltage control, graphical monitoring, profiles, or overlays are central requirements.
