MorePowerTool (MPT) is a free community tool for AMD Radeon GPUs.
It lets you unlock and adjust advanced power limits, TDC, fan curves, voltage, and other hidden settings that AMD’s WattMan normally restricts.
Users load a GPU BIOS dump, tweak the SoftPowerPlayTable (SPPT) values, and flash the changes for higher performance. It’s popular for overclocking Navi cards but has limits on newer generations.

| OS | Windows 10 / Windows 11 (64-bit) |
| License | Freeware — community-distributed |
| Key features | Power limits (TGP/PPT/TDC), voltage curve edits, memory timing tuning, clock limits, fan and thermal limits, power table edits without BIOS flashing. |
| Risks | Void warranty, instability, possible hardware damage if misused, sometimes reset by driver updates. Requires admin rights and technical care. |
| Typical workflow | Launch as admin → load current SPPT → change parameters → write SPPT → restart driver/system → test stability (use monitoring tools). |
| Alternatives | MSI Afterburner, AMD Radeon Software, OverdriveNTool (older cards), Red BIOS Editor (BIOS flashing) |
