16) CLR_CMOS (Clear CMOS Jumper)
Use this jumper to clear the BIOS configuration and reset the CMOS values to factory defaults. To clear
the CMOS values, use a metal object like a screwdriver to touch the two pins for a few seconds.
• Always turn off your computer and unplug the power cord from the power outlet before clearing
the CMOS values.
• After system restart, go to BIOS Setup to load factory defaults (select Load Optimized Defaults) or
manually configure the BIOS settings (please navigate to the "BIOS Setup" page of GIGABYTE's
website for more information).
17) SPDIF_O (S/PDIF Out Header)
This header supports S/PDIF digital output, which allows you to connect a S/PDIF digital audio cable to
output digital audio from your motherboard to the supported audio devices. For information about connecting
the digital audio cable, carefully read the manual for your audio devices.
