Inno3D TuneIT vs nvuv

INNO3D TuneIT OC & RGB Utility V5.02 is a free Windows utility for overclocking and RGB control on listed INNO3D GeForce graphics cards. Its controls include GPU and memory clocks, fan speed, target power, and target temperature. The home page displays GPU clock, temperature, fan speed, memory profiles, driver version, and BIOS version, with real-time GPU monitoring available. RGB settings let users select a mode, change brightness and effect speed, or create a custom effect. Users can also change software startup options. The listed release supports GeForce 50, 40, 30, 20, 16, 10, 900, and 700 Series cards and specifies Windows 11 or Windows 10 64-bit. INNO3D provides a download link and a technical support form requesting product details, hardware configuration, and a problem description. For RMA requests, the support form directs customers to the store where the graphics card was purchased.

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.
