A55 (Hudson D2) FCH Chipset

AMD

®

A55 FCH (Hudson D2) is designed to support up to 5GT/s interface

and PCI Express 2.0 x 16 (at x4 speed) graphics.

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.

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.

ASUS DIGI+ VRM

DIGI+ Power Control: Digital Power Design for the APU*

ASUS motherboards using the AMD

®

A55 chipset employ precise digital

voltage regulation for the CPU, called DIGI+ VRM (Voltage Regulation

Modules) digital power design. The CPU voltage and VRM frequency

are adjusted via either carefully developed automated modes, or by

using user-defined profiles. The effect is that DIGI+ VRM technology

ensures greater energy efficiency and the most precise power delivery.

Boosted by world-renowned ASUS quality, it creates an ideal computing

platform for a diverse range of applications, from gaming to multimedia

or office work and heavy multitasking. Engineered and tested to assure

unmitigated performance, ASUS A55 boards with DIGI+ VRM remain

efficient and accurate, for reliable application in every scenario.

* DIGI+ VRM functions also available in FM1 socket compatible CPUs.

EPU

Tap into the world’s first real-time PC power saving chip through the AI

Suite II utility. Get total system-wide energy optimization by automatically

detecting current PC loadings and intelligently moderating power

consumption. This also reduces fan noise and extends component

longevity.
