AMD
®
Socket AM2 Athlon™ / Sempron™ CPU support
The motherboard supports AMD
®
Socket AM2 Athlon™ processors. It
features 2000 / 1600 MT/s HyperTransport™-based system bus, dual-
channel un-buffered DDR2 800 memory support and AMD™ Cool ‘n’
Quiet™ Technology.
HyperTransport™ 3.0 support
HyperTransport™ 3.0 technology provides 2.6 times more bandwidth
than HT1.0 that radically improves system efciency for a smoother,
faster computing environment.
64-bit CPU support
64-bit computing, the next generation technology to replace the current
32-bit architecture, delivers advanced system performance, faster
memory access, and increased productivity. This motherboard provides
excellent compatibility and exibility by supporting either 64-bit or 32-bit
architecture.
Dual-core CPU
Enjoy the extraordinary CPU power from the latest dual-core CPU. The
advanced processing technology contains two physical CPU cores with
individually dedicated L2 cache to satisfy the rising demand for more
powerful processing capability.
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.
AMD Cool ‘n’ Quiet Technology
The 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.
Dual channel DDR2 1066 support
This motherboard supports DDR2 1066, which provides faster data
transfer rate and more bandwidth to increase memory data transfer
rate and computing efciency. This enhances system performance in
3D graphics and other memory demanding applications.
• DDR2 1066 is supported by AM2+ CPU only. Refer to the ASUS website at
www.asus.com for the supported CPU models.
• Due to AM2+ 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.
PCI Express 2.0 support
This motherboard supports the latest PCIe 2.0 devices for double
speed and bandwidth which enhances system performance.
