ThrottleStop: Monitor and Control CPU Performance

ThrottleStop is a free utility for Windows that allows users to monitor and control their CPU performance. It can be used to undervolt a CPU to reduce power consumption and heat output, overclock a CPU for increased performance, and adjust other advanced processor settings.

What is ThrottleStop?

ThrottleStop is a popular free software for advanced Windows users that gives them control over their CPU performance. It allows monitoring and tweaking various aspects of the processor like temperature, voltage, clock speeds, etc.

Some of the key features of ThrottleStop include:

  • Undervolting the CPU - Reduce voltage to lower temperatures and power draw without impacting stability and performance.
  • Overclocking the CPU (unlocked Intel CPUs only) - Increase clock speeds to boost performance in games and applications.
  • Adjust multiplier, bus speed, thermal throttling limits
  • Benchmark stress testing
  • Control over turbo boost power limits

ThrottleStop has an intuitive interface that displays graphs for temperature, clock speeds and other readings. It works well for enthusiasts and power users who want to optimize their Intel CPUs for heat, battery life or performance. It requires a good understanding of overclocking principles to use its advanced features correctly. Overall, it's a lightweight tool that gives significant control over processor behavior.
