EVGA Precision X1 vs nvuv

EVGA Precision X1 is free GPU tuning software for Windows, with controls for clocks, voltage, fans, RGB lighting, and monitoring. Its OC Scanner tests a graphics card for a stable overclock and offers additional testing modes. Users can set GPU and memory clocks, voltage, and independent voltage and frequency points. Fan speed, curves, and profiles are adjustable, though the available options depend on the graphics card. RGB controls cover graphics cards and NVLink Bridges; LED Sync can coordinate with other EVGA RGB components. On supported EVGA cards, the software provides real-time wattage monitoring and an on-screen display of system vitals. It supports up to 10 profiles with hotkeys and includes an in-game screenshot function. Listed system requirements specify GeForce RTX, GTX 16 Series, and GTX 10 Series cards, plus Windows 10 64-bit or Windows 8 64-bit. EVGA offers a standalone version and links to a Steam version. The listed GPU control features require EVGA graphics cards.

nvuv is a free Linux command-line utility for adjusting NVIDIA GPU power and clock behavior. It can set power limits, lock GPU or memory clock ranges, and apply offsets to either clock. On systems with several GPUs, the `-i GPU_INDEX` option chooses the device. The project describes nvuv as a thin wrapper around NVIDIA’s NVML library. Its indirect undervolting method locks the GPU’s maximum clock and applies a positive offset because direct voltage control is not exposed on Linux. The project says this can preserve roughly similar performance while lowering voltage and power draw, with possible reductions in temperature and fan noise. Settings may come from a TOML file, using `/etc/nvuv/nvuv.toml` by default. Applying, changing, or resetting settings requires root privileges. Changes do not survive reboot, resume, or driver reload unless the supplied systemd service reapplies them. That service can run at startup and after resume or driver reload.
