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.
Native DDR2 1066 support
This motherboard supports native DDR2 1066. It provides faster data
transfer rate and more bandwidth to increase memory computing
efficiency, enhancing system performance in 3D graphics and other
memory demanding applications.
• DDR2 1066 is supported by AM3 / AM2+ CPU only. Refer to www.asus.com for the AM3
/ AM2+ CPU models.
• Due to AM2+ / AM3 CPU limitation, only one DDR2 1066 DIMM is supported per
channel. When four DDR2 1066 DIMMs are installed, all DIMMs run at 800MHz
frequency by default for system stability.
Hybrid CrossFireX support
ATI Hybrid CrossFireX™ technology greatly boosts graphics performance
with an onboard GPU and a discrete graphics card.
• Hybrid CrossFireX is supported by Windows ® Vista OS only.
• Refer to www.amd.com for the discrete GPUs which support Hybrid CrossFireX™.
