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 efciency 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.
DDR3 1800(O.C.) support
The motherboard supports DDR3 memory that features data transfer
rates of 1800 (O.C.)/1600 (O.C.)/1333/1066 MHz to meet the higher
bandwidth requirements of the latest operation system, 3D graphics,
multimedia, and Internet applications. The dual-channel DDR3
architecture doubles the bandwidth of your system memory to boost
system performance, eliminating bottlenecks with peak bandwidths of up
to 25.6 GB/s. Furthermore, the supply voltage for the memory is reduced
from 1.8 V for DDR2 to just 1.5 V for DDR3. This voltage reduction limits
the power consumption and heat generation of DDR3 which makes it an
ideal memory solution.
PCI Express 2.0 support
This motherboard supports PCI Express 2.0 devices for double speed
and bandwidth which enhances system performance.
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 graphics GPU.
• Hybrid CrossFireX™ is supported by Windows
®
Vista OS only.
• Refer to
www.amd.com for the discrete GPUs which support Hybrid CrossFireX™.
