MoreClockTool vs MSI Afterburner

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.

MSI Afterburner is Windows software for tuning graphics cards and monitoring hardware in real time. Its controls cover GPU clock frequency, voltage, power limits and fan speed, and users can set fan curves and save tuning profiles. MSI says it works with graphics cards from all brands, not only its own. OC Scanner can find the highest stable overclock settings for a card. While gaming, an on-screen display can show live system performance information. The page also describes Predator, a separate recording tool for games or overclocking that supports H.264, WMV and AVI formats. MSI lists a free plan at free, with overclocking and undervolting, hardware monitoring, custom fan control and an on-screen display. There is no free trial. MSI lists versions 4.6.6 (Final) and 4.6.7 (Beta), both released in September 2026. It warns that phishing sites may steal data and identifies msi.com and Guru3D as the correct sites.
