MorePowerTool review
Free Windows tuning utility for experienced AMD Radeon overclocking and undervolting.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MorePowerTool is a free Windows utility for modifying AMD Radeon tuning parameters beyond standard Wattman controls. It is aimed at experienced enthusiasts exploring overclocking or undervolting on supported Radeon GPUs from Vega through RDNA 2, including supported Navi models. The tool can adjust power, voltage, frequency and fan-control limits, while also enabling or disabling Wattman overdrive features. The publisher warns that inappropriate settings can cause instability or permanent hardware damage, so it is not a natural fit for users seeking a simple, guided tuning experience.
Its main strength is the depth of its Radeon control surface. MorePowerTool adjusts Wattman power and voltage limits, GPU frequency limits and clock settings, fan-control and Zero RPM parameters, debug overrides, and throttler controls. It can also load and save MPT settings files, then export settings as a Windows registry file. That combination supports repeatable configuration and gives experienced users more control than standard Wattman settings alone. The published information identifies version 1.3.19 and describes support through RDNA 2, but the team states there is no conventional MPT for RDNA3.
MorePowerTool is a focused utility rather than a complete monitoring suite. Its free pricing and Windows-only delivery make it straightforward to consider for AMD Radeon owners who want low-level tuning controls without a paid tier. However, the lack of verified monitoring or overlay features means users may need other software for visibility while tuning. Choose it for extensive Radeon power, voltage, frequency, fan and settings-file controls; choose an alternative if you need broader GPU-vendor support, RDNA3 coverage, or integrated monitoring and overlays.
