In their own words
amdgpu-clocks
amdgpu-clocks is a free, GPL-2.0-licensed Linux script for setting custom power states on AMD GPUs that use the amdgpu kernel driver. Where the hardware exposes the controls, it can adjust GPU and memory clocks, voltages, power caps, performance levels, and power profiles. The project says it should work with Polaris, Vega, Navi, and RDNA cards, but Vega GPUs in AMD APUs lack the required API. It can manage multiple cards, with custom state files selected by card identifier or PCI address. Users define settings in files under /etc/default. Fine-grained control requires Radeon OverDrive to be enabled in the kernel. A systemd service can apply states at startup, and a resume script can reapply them after suspend. For RDNA 3 and newer, it can handle driver-exposed Zero RPM fan settings; these require Linux 6.13 or newer, and stop-temperature control is available only on RDNA 3. A restore option returns states to their initial defaults, except the power profile, which it sets to 0. The README directs installation to /usr/local/bin; the GitHub releases page lists no releases.
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.
