is a powerful command-line utility for Windows designed specifically to reprogram the P-states (Performance States) of various AMD CPUs and APUs. Originally developed to tweak processors utilizing AMD’s Cool'n'Quiet and Turbo Core technologies, it allows users to modify processor multipliers and core voltages directly through the operating system.
: To ensure settings persist after a reboot, create a new task in the Windows Task Scheduler with "Run with highest privileges" enabled. Important Safety Considerations
: While originally built for older Windows versions, users have reported difficulty running it on Windows 10 due to compatibility and driver issues. amdmsr tweaker v11 64 bit free
This will print a list of active P-states (e.g., P0, P1, P2) alongside their corresponding frequencies and VID (voltage ID) codes. Modifying a P-State
Improper settings can lead to immediate system freezes or BSOD (Blue Screen of Death). is a powerful command-line utility for Windows designed
: The target power profile (e.g., P0 for maximum performance). Multiplier : The target CPU core multiplier.

The information provided is for educational purposes only, and users assume all risks. Official sources like AMD confirm that any form of manual overclocking can damage your processor and void your warranty. Important Safety Considerations : While originally built for
: Enables power saving even on overclocked systems by allowing the CPU to drop to lower power states when idle.
If your machine experiences an accidental hard lockup due to an aggressive undervolt, simply press the physical chassis reset switch. Because your configuration isn't permanently flashed into the hardware BIOS memory, cycling system power completely purges volatile MSR registries back to factory defaults.
Because the command resets when the PC restarts, many advanced users utilize the Windows Task Scheduler to automate their P-state tweaks at every system boot. You can configure a hidden task that triggers at .
