Summary

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 support for RDNA 2 and RDNA 3, and an April 2025 update added RDNA 4 compatibility. 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; the maker points users to MorePowerTool for further memory and fan settings. 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, noting that higher voltages can damage hardware.

Who it is for

MCT is intended for experienced users evaluating supported newer AMD graphics cards. It is not presented for routine production use with all settings around the clock.
