Facts

Purpose
NVIDIA_OC Daemon is a Rust daemon for applying NVIDIA GPU overclocking settings through NVML.github.com · 30 Sept 2026
Target systems
It is intended for systems where X.Org Coolbits tools such as GreenWithEnvy or nvidia-settings are unavailable or undesirable, including Wayland setups.github.com · 30 Sept 2026
Configuration
The daemon loads TOML configuration from /etc/nvidia_oc/config and applies GPU clock offsets, memory clock offsets, and power limits.github.com · 30 Sept 2026
Reloading
It watches /etc/nvidia_oc recursively and reloads modified configuration after a five-second debounce.github.com · 30 Sept 2026
First-run setup
On first run, it generates /etc/nvidia_oc/config from the currently reported GPU settings.github.com · 30 Sept 2026
Per-device controls
Configuration supports per-device GPU frequency offsets, memory frequency offsets, and power management limits.github.com · 30 Sept 2026
Logging
The daemon logs to the terminal and to demon.log in its process working directory.github.com · 30 Sept 2026
Requirements
It requires Linux with a supported NVIDIA GPU and an NVIDIA driver exposing NVML as libnvidia-ml.so.github.com · 30 Sept 2026
Build and privileges
Building requires a Rust toolchain, and creating the configuration or applying settings requires root or equivalent permissions.github.com · 30 Sept 2026
Integration
The project uses NVIDIA Management Library through nvml-wrapper and direct NVML bindings.github.com · 30 Sept 2026
Safety warning
The README warns that overclocking and changing GPU power limits can crash systems, damage hardware, void warranties, or make a machine unbootable.github.com · 30 Sept 2026
Hardware limits
Some laptop GPUs or driver/device combinations may not support querying or setting power limits, and NVML calls can fail when operations are not exposed.github.com · 30 Sept 2026
Deployment limit
The repository does not currently include a systemd unit.github.com · 30 Sept 2026
License
The software is distributed under the MIT License, which grants permission to use, copy, modify, publish, distribute, sublicense, and sell copies subject to license conditions.github.com · 30 Sept 2026
