In their own words
Green Curve
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.
MoreClockTool
MoreClockTool (MCT) is a free Windows utility for simpler overclocking of newer AMD graphics cards, intended to complement MorePowerTool and Red BIOS Editor. The maker lists RDNA 2 and RDNA 3 support, with RDNA 4 compatibility added in an April 2025 update. Users can enter minimum and maximum clock frequencies in MHz, limit voltage increases, and adjust GPU power by percentage. MCT can save and load multiple settings profiles, including profiles created in Wattman. Its Set control applies changes in real time, while Reset restores factory defaults. It also includes a Memory Fast Timing Level setting and fan controls analogous to Wattman; for further memory and fan settings, the maker points users to MorePowerTool. The download page lists MCT 1.1.11 Version 2, dated 12.04.2025, with ADLX 1.4 support, RDNA4 bug fixes, and an ImageSharpening Sharpen Desktop feature. The maker describes use as experimental and at the user's own risk, warning that higher voltages may damage hardware and that the tool is not intended for all-settings production use around the clock.
