AMDMsrTweaker is a lightweight, command-line utility designed to modify the Model Specific Registers (MSR) of AMD processors. Unlike BIOS overclocking, which is static, or heavy GUI software like AMD OverDrive, AMDMsrTweaker allows users to adjust P-States (Power States) on the fly directly within Windows.
Always verify system stability incrementally using testing software like or AIDA64 before permanently writing commands into a startup automation script.
Modern processors don't just run at one speed; they step up or down based on what you are doing to save power and reduce heat. These steps are called P-States. amdmsr tweaker v11 64 bit
