Noise Filter
This feature detects repetitive and stationary noises (non-voice signals)
like computer fans, air conditioners, and other background noises then
eliminates it in the incoming audio stream while recording.
C.P.R. (CPU Parameter Recall)
The BIOS C.P.R. feature automatically restores the CPU default settings
when the system hangs due to overclocking failure. C.P.R. eliminates the
need to open the system chassis and clear the RTC data. Simply shut
down and reboot the system, and the BIOS automatically restores the
CPU parameters to their default settings.
