NVIDIA_OC Daemon

What NVIDIA_OC Daemon is

NVIDIA_OC Daemon is a free Rust daemon for applying NVIDIA GPU overclocking settings through NVML on Linux. It is intended for systems where X.Org Coolbits tools such as GreenWithEnvy or nvidia-settings are unavailable or undesirable, including Wayland setups. The daemon reads TOML settings from /etc/nvidia_oc/config for GPU clock offsets, memory clock offsets, and power limits, with controls available per device. On first run it creates the configuration file from currently reported GPU settings. It watches /etc/nvidia_oc recursively and reloads changes after a five-second debounce. Logs go to the terminal and to demon.log in the process working directory. It requires a supported NVIDIA GPU and a driver exposing NVML as libnvidia-ml.so. Building requires a Rust toolchain, while creating configuration or applying settings requires root or equivalent permissions. The repository does not include a systemd unit. The project warns that overclocking and power-limit changes can crash systems, damage hardware, void warranties, or leave a machine unbootable; some laptop GPUs or driver and device combinations may not expose power-limit operations.
