Sempron™ processors (socket AM2+/AM2)
This motherboard supports AMD ® Socket AM2+ multi-core processors.
It features dual-channel DDR2 1066 memory support, data transfer rate
up to 5200MT/s via HyperTransport™ 3.0 based system bus, and AMD ®
Cool ‘n’ Quiet™ Technology.
AMD ® 770 Chipset
The AMD ® 770 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.) support
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.
64-bit CPU support
64-bit computing 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.
