What MoreClockTool is
MoreClockTool (MCT) is a free Windows utility for experienced users evaluating overclocking settings on newer AMD graphics cards. It is intended to complement MorePowerTool and Red BIOS Editor and replace AMD Wattman for simpler overclocking. 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 to the system in real time, while Reset restores factory defaults. Memory Fast Timing Level and fan controls are included; for further memory and fan settings, the maker directs users to MorePowerTool. The listed release is 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. Higher voltages may damage hardware, and it is not intended for all-settings use in production systems around the clock.
