AMD

®

785G Chipset

The AMD

®

785G Chipset is designed to support up to 5200MT/s

HyperTransport™ 3.0 (HT 3.0) interface speed and PCI Express 2.0

x16 graphics. It is optimized with AMD’s latest AM3 multi-core CPUs to

provide excellent system performance and overclocking capabilities.

HyperTransport™ 3.0 support

HyperTransport™ 3.0 technology provides 2.6 times more bandwidth

than HT1.0 that radically improves system efﬁciency for a smoother and

faster computing environment.

AMD Cool ‘n’ Quiet Technology

This motherboard supports the AMD Cool ‘n’ Quiet technology which

monitors system operation and automatically adjusts CPU voltage and

frequency for a cool and quiet operating environment.

DDR2 1200 (O.C.)

This motherboard supports DDR2 1200 (O.C.) that provides faster

data transfer rate and more bandwidth to increase memory computing

efﬁciency, enhancing system performance in 3D graphics and other

memory demanding applications.

S/PDIF digital sound ready

This motherboard provides convenient connectivity to external home

theater audio systems via coaxial and optical S/PDIF_OUT (SONY-

PHILIPS Digital Interface) jacks. The S/PDIF transfers digital audio

without converting it to analog format and keeps the best signal quality.

Hybrid CrossFireX™ support

ATI Hybrid CrossFireX™ technology greatly boosts graphics performance

with an onboard GPU and a discrete GPU.

•

Hybrid CrossFireX™ is supported by Windows

®

Vista OS only.
