Dolby® Digital Live™ The CMI9880 audio CODEC comes with an AC-3 encoder capable of transforming your computer's digital audio contents into real-time Dolby® Digital stream. This digital stream passes through the S/PDIF out interfaces to an AC-3 decoder for 7.1-channel playback. See page 5-18 for details. S/PDIF digital sound ready The motherboard supports the S/PDIF technology through the S/PDIF interfaces on the rear panel and at midboard. The S/PDIF technology turns your computer into a high-end entertainment system with digital connectivity to powerful audio and speaker systems. See pages 2-24 and 2-29 for details. IEEE 1394b/a support The motherboard implements the IEEE 1394b standard that allows up to 800 Mbps transfer rates, and increases the computer-to-electronic device operational distance from 4.5 meters to 100 meters. IEEE 1394b maintains backward compatibility with IEEE 1394a (400 Mbps), keeping vital characteristics such as plug-and-play and peer-to-peer connectivity. See pages 2-23, 2-31, and 5-8 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 2-24 and 2-30 for details. Gigabit and wireless LAN solutions The motherboard comes with dual Gigabit and onboard wireless LAN controllers to provide a total solution for your networking needs. The Gigabit LAN controllers uses the PCI Express segment to provide faster data bandwidth. The onboard wireless LAN controller supports up to 54 Mbps data transmission for your wireless Internet, LAN, and file sharing requirements. See pages 2-23, 2-24, and 2-33 for details. Temperature, fan, and voltage monitoring The CPU temperature is monitored by the ASIC (integrated in the Winbond Super I/O) to prevent overheating and damage. The system fan rotations per minute (RPM) is monitored for timely failure detection. The ASIC monitors the voltage levels to ensure stable supply of current for critical components.
