EVGA Precision X1 vs Green Curve

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.

Green Curve is a free, open-source utility for adjusting NVIDIA GeForce GPU behavior on Windows and Linux. It can inspect and edit live voltage/frequency curves, core and VRAM offsets, power targets, and fan settings. Supported GeForce architectures run from Pascal through Blackwell, with a best-effort fallback for future architectures. Users can save five profiles, switch them with global hotkeys, or switch automatically based on the foreground application. Fan options include driver auto, fixed speed, and temperature curves with up to eight points. A command-line interface supports hardware probing, profile changes and live-state output in text or JSON. Windows has a native GUI; Linux has a keyboard- and mouse-navigable terminal UI. The application loads NVAPI and NVML from the installed NVIDIA driver rather than bundling proprietary driver binaries. The project states it has no telemetry, analytics, cloud tracking or remote error reporting. Windows x64 and Linux x64 are validated on NVIDIA hardware; ARM64 platforms are compile targets without completed live hardware validation. The project warns that tuning may cause instability or hardware damage.
