EVGA Precision X1 vs NVIDIA_OC Daemon

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.

NVIDIA_OC Daemon is a Linux daemon that applies NVIDIA GPU overclocking settings through NVML. 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 changed configuration after a five-second debounce. Logs go to the terminal and to demon.log in the process working directory. The software requires Linux, a supported NVIDIA GPU, and a driver exposing NVML as libnvidia-ml.so. Building requires a Rust toolchain; creating configuration or applying settings requires root or equivalent permissions. Some laptop GPUs or driver and device combinations may not expose power-limit operations. 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 make a machine unbootable.
