Clock Tuner for Ryzen (CTR) is a automated tuning software created by Yuri Bubliy (known as 1usmus) that speeds up AMD processors by optimizing performance at the Core Complex (CCX) level. Unlike traditional overclocking utilities that apply a blanket speed and voltage across the entire processor, CTR evaluates each individual core’s silicon quality to find the maximum possible frequency at the lowest stable voltage. This process yields a free performance boost of roughly 10% to 15% while keeping power consumption and temperatures down. System Prerequisites
Before using CTR, your computer must meet the following hardware and software guidelines:
Supported CPU: AMD Ryzen based on Zen 2 or Zen 3 architecture (e.g., Ryzen 3000, 4000G, or 5000 series desktop chips).
Motherboard: AM4 socket boards with an A320, B350, X370, B450, X470, B550, or X570 chipset.
Required Support Software: You must have .NET Framework 4.6 (or newer) installed, alongside the official AMD Ryzen Master utility, which provides the underlying monitoring library. Mandatory BIOS Preparations
To allow the software to safely interact with your hardware, restart your computer, enter your motherboard’s BIOS, and apply these exact adjustments: CPU Voltage (Vcore): Set to Auto. Precision Boost Overdrive (PBO): Set to Disabled.
CPU Load Line Calibration (LLC): Change this to Level 3 or Medium (Level 4 for ASUS boards). Core Performance Boost: Set to Auto or Enabled.
Global C-State Control: Set to Enabled to ensure stable power delivery when idling. Step-by-Step Guide to Using CTR
