8-channel high definition audio

Onboard is the C-Media CMI9880L 7.1-channel audio CODEC. This CODEC is
fully-compliant with Intel

High Definition Audio standard (192 KHz, 24-bit

audio). With the CODEC, 8-channel audio ports, and S/PDIF interfaces, you
can connect your computer to home theater decoders to produce
crystal-clear digital audio.

The CMI9880L CODEC comes with a software application that features jack
detection to monitor the plugging status of each jack, impedance sensing
to determine audio device classes, and pre-defined equalization for various
audio devices. See page 1-26 and 1-27 for details.

S/PDIF digital sound ready

The motherboard supports the S/PDIF Out function through the midboard
S/PDIF interface. The S/PDIF technology turns your computer into a high-end
entertainment system with digital connectivity to powerful audio and speaker
systems. See page 1-27 for details.

USB 2.0 technology

The motherboard implements the Universal Serial Bus (USB) 2.0
specification, dramatically increasing the connection speed from the
12 Mbps bandwidth on USB 1.1 to a fast 480 Mbps on USB 2.0. USB 2.0 is
backward compatible with USB 1.1. See pages 1-27, 1-31, and 2-22 for
details.

Temperature, fan, and voltage monitoring

The CPU temperature is monitored by the Winbond Super I/O to prevent
overheating and damage. The system fan rotation per minute (RPM) is
monitored for timely failure detection. The Winbond Super I/O monitors the
voltage levels to ensure stable supply of current for critical components.
