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 denition audio
The onboard 8-channel HD audio (High Denition Audio, previously
codenamed Azalia) CODEC enables high-quality 192KHz/24-bit audio
output and jack-detect feature that automatically detects and identies
what types of peripherals are plugged into the audio I/O jacks and noties
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 efcient power
management for advanced operating systems.
1.3.2 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-dened proles. The effect is that DIGI+ VRM technology
ensures greater energy efciency 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 ofce work and heavy multitasking. Engineered and tested to assure
unmitigated performance, ASUS A55 boards with DIGI+ VRM remain
efcient and accurate, for reliable application in every scenario.
* DIGI+ VRM functions also available in FM1 socket compatible CPUs.
EPU
Tap into the world’s rst 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.
