The tool allows you to manually adjust multipliers and voltages for different P-States. Version 1.1 introduced support for Trinity, Richland, and preliminary Kaveri architectures. : Athlon and Phenom models. Family 12h & 14h : Llano, Ontario, and Zacate.
: Available in both 32-bit and 64-bit (x64) versions. For 64-bit Windows, users must typically use the contents of the folder within the distributed package. amdmsr tweaker v11 64 bit free
AMD MSR Tweaker acts as a GUI (Graphical User Interface) alternative to command-line tools like msr-tools . It communicates directly with the CPU core to read and write values that control voltage and frequency. Unlike overclocking software such as AMD Overdrive or Ryzen Master, MSR Tweaker is minimalistic, requires no installation, and focuses specifically on P-State manipulation. The tool allows you to manually adjust multipliers
: Allows users to manually set the multiplier and voltage for different performance levels (P0, P1, etc.). Power Management Control : Can enable or disable Application Power Management (APM) Turbo Core technology. Stability Tuning Family 12h & 14h : Llano, Ontario, and Zacate
Changes revert immediately after writing. Fix: Another process (e.g., AMD Ryzen Master, MSI Afterburner) is overwriting the MSR. Close all other tuning software.
To ensure your custom settings apply automatically every time you log in, you can create a batch file (.bat) and schedule it:
(power states) of various AMD CPUs and APUs. It is primarily used by enthusiasts to optimize performance through overclocking or to improve power efficiency via undervolting. Core Functionality P-State Customization
