In their own words
ASUS GPU Tweak III
ASUS GPU Tweak III is free Windows software for adjusting parameters on NVIDIA and AMD desktop graphics cards, including overclocking, voltage, and fan control. OC Scanner automatically optimizes clock speeds for NVIDIA cards and saves a profile without overwriting driver data. The Voltage-Frequency Tuner manages the GPU boost curve through multiple input methods. Profile Connect can load linked overclock, fan-curve, and OSD settings when a selected application runs. Users can configure GPU fans and system fans connected to FanConnect headers with curves or fixed RPM settings. Monitoring includes fan RPM and system power metrics, system information over full-screen apps, and log export for analysis. A hardware plug-in adds real-time component statistics, while the OSD has adjustable display properties. ASUS lists Windows 10 and 11, 2 GB RAM, and 200 MB storage as minimum requirements for most versions. Power Detector+ compatibility is limited to specified ROG cards. The listed stable release is version 2.1.9.5, dated September 18, 2026.
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.
