Amdmsr Tweaker V11 64 — Bit

Released around April 2013, AmdMsrTweaker v1.1 brought crucial updates that broadened its applicability. The key changes included:

Type the command you wish to run (e.g., C:\AMDMsrTweaker\AMDMsrTweaker.exe -p0 12 1A ). Save the file as overclock.bat .

— Disables TDP limiting (useful for Bulldozer-based chips). Implementation Tips Persistence

Laptop APUs are notorious for running hot. For example, on a Carrizo‑based notebook, users have successfully lowered the voltage of the P0 state from 1.1V (as reported by the tool) to around 1.0875V, which corresponded to a real‑world reduction from 1.325V to about 1.319V according to HWInfo. This small change can reduce temperatures by several degrees under load.

The hex or decimal value that determines the target clock speed.

: Improved support for different voltage increments across various platforms. 64-bit Native Support

The "v11 64-bit" iteration is often cited as a "sweet spot" build for several reasons:

AMD’s APM (Application Power Management) feature, which enforces a TDP limit, can cause severe throttling under sustained loads, especially on FX‑series CPUs. Users have reported that running AmdMsrTweaker.exe APM=0 completely resolves throttling issues, allowing the processor to maintain full turbo frequencies. amdmsr tweaker v11 64 bit

The tool requires kernel-level access to modify registers.

4.5/5

Because the tool writes to protected CPU registers, it requires elevated privileges. Right-click the executable and select .

Lowering the CPU voltage (undervolting) reduces heat generation and power consumption without sacrificing clock speed. AMDMSRTweaker allows you to tune the voltage of individual P-states, keeping your system cool during intense workloads and exceptionally efficient when idling. 2. Tailored Overclocking Released around April 2013, AmdMsrTweaker v1

Optimized natively for x64 versions of Windows. How It Works: Understanding P-States

The developer community remains active, with forks adding support for the and even Strix Point mobile chips. While version 11 is not the newest (v12 and v13 exist in beta), v11 remains the most stable “gold release” for 64-bit Windows 10/11.

After applying a tweak, run a heavy workload tool like Prime95 or Cinebench for at least 15–30 minutes to ensure the CPU does not crash under the new settings. — Disables TDP limiting (useful for Bulldozer-based chips)
