Ryzen Controller: Fine-Grained Control for AMD Ryzen Processors

Free, open-source utility for adjusting TDP limits and advanced CPU parameters for optimized performance and power management of AMD Ryzen processors.

What is Ryzen Controller?

Ryzen Controller is an open-source utility program developed specifically for AMD Ryzen processors. It gives users more control over their CPU's performance and power consumption settings.

The main feature of Ryzen Controller is the ability to adjust the processor's TDP (Thermal Design Power) limits. TDP determines the maximum amount of power and heat output allowed for the CPU. Lowering the TDP can reduce temperatures and fan noise, while raising it can boost performance.

In addition to TDP adjustment, Ryzen Controller lets you modify other advanced CPU parameters like voltage, clock speed multipliers, memory timings, and more. This allows for finer tuning compared to what's available in the BIOS. It can be useful for optimizing performance, overclocking, undervolting to save power, or finding a quieter acoustic profile.

The program has a simple and straightforward interface that displays usage statistics and graphs to help visualize the effects of settings changes. It includes real-time monitoring and temperature logging as well. Ryzen Controller is free to use and open source software compatible with most AMD Ryzen desktop processors.
