ASUS GPU Tweak III vs nvuv

ASUS GPU Tweak III is free Windows software for adjusting parameters on NVIDIA and AMD desktop graphics cards, including overclocking, voltage, and fan control. OC Scanner automatically optimizes clock speeds for NVIDIA cards and saves a profile without overwriting driver data. The Voltage-Frequency Tuner manages the GPU boost curve through multiple input methods. Profile Connect can load linked overclock, fan-curve, and OSD settings when a selected application runs. Users can configure GPU fans and system fans connected to FanConnect headers with curves or fixed RPM settings. Monitoring includes fan RPM and system power metrics, system information over full-screen apps, and log export for analysis. A hardware plug-in adds real-time component statistics, while the OSD has adjustable display properties. ASUS lists Windows 10 and 11, 2 GB RAM, and 200 MB storage as minimum requirements for most versions. Power Detector+ compatibility is limited to specified ROG cards. The listed stable release is version 2.1.9.5, dated September 18, 2026.

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.
