Many new computer motherboards and processors have varying forms of CPU Throttling and Power Management Utilities that are designed to reduce the speed of the CPU to preserve energy whenever the system load allows this. Unfortunately, these utilities can have a negative effect on any active audio playback- or recording task which will be audible as noise bursts, pops & clicks, or distortion. Most computers allow these features to be turned off from the BIOS.

Some examples of these CPU Throttling and Power Management Utilities to look for and disable include:

AI Tweaker
CPC C-State
C1E
Intel EIST
Intel Speedstep (sometimes just called "Speedstep")
HPET (High Precision Event Timer)

Please refer to your motherboard’s documentation for specific information about the available CPU Throttling and Power Management Utilities, as well as how to access and make changes to your computer’s BIOS.
