64-bit CPU support

64-bit computing, the next generation technology that replaces the

current 32-bit architecture, delivers advanced system performance, faster

memory access, and increased productivity. This motherboard provides

excellent compatibility and flexibility by supporting both 64-bit and 32-bit

architecture.

Gigabit LAN solution

The onboard LAN controller is a highly integrated Gb LAN controller. It is

enhanced with an ACPI management function to provide efficient power

management for advanced operating systems.

Serial ATA 3Gb/s technology and SATA-On-The-Go

This motherboard supports hard drives based on the Serial ATA (SATA)

3Gb/s storage specification, delivering enhanced scalability and doubling

the bus bandwidth for high-speed data retrieval and save. The external

SATA port provides smart setup and hot-plug functions for easy data

backup to external devices.

8-channel high definition audio

The onboard 8-channel HD audio (High Definition Audio, previously

codenamed Azalia) CODEC enables high-quality 192KHz/24-bit audio

output and jack-detect feature that automatically detects and identifies

what types of peripherals are plugged into the audio I/O jacks and notifies

users of inappropriate connection, which means there will be no more

confusion of Line-in, Line-out, and Mic jacks.
