AMDMSR Tweaker V1.1 is a lightweight, portable utility designed for advanced users and enthusiasts looking to optimize their AMD processor performance. This 64-bit release allows for real-time manipulation of Model-Specific Registers (MSRs), enabling fine-tuned control over CPU parameters that are typically locked or hidden within the BIOS.
AmdMsrTweaker is a lightweight command-line utility designed for Windows (x64 and x86) to reprogram the (Performance States) of AMD CPUs and APUs. It is primarily used to undervolt for power savings or to overclock by modifying the clock multipliers and voltages of various power states. 🛠️ Key Capabilities AMDMSR Tweaker V1.1 64 Bit
