1.3 Special features
1.3.1 Product highlights
Green ASUS
This motherboard and its packaging comply with the European Union’s Restriction
on the use of Hazardous Substances (RoHS). This is in line with the ASUS vision
of creating environment-friendly and recyclable products/packaging to safeguard
consumers’ health while minimizing the impact on the environment.
Intel
®
Core™2 Extreme / Core™ 2 Quad /
Core™2 Duo Processor Support
This motherboard supports the latest Intel
®
Core™ 2 Extreme / Core™ 2 Quad /
Core™ 2 Duo processors in the LGA775 package. It is excellent for multi-tasking,
multi-media and enthusiastic gamers with 1600 / 1333 / 1066 / 800 MHz FSB. The
Intel
®
Core™ 2 series processor is one of the most powerful CPUs in the world.
This motherboard also supports Intel
®
CPUs in the new 45nm manufacturing
process.
Intel X48 Chipset
The Intel
®
X48 Express Chipset is the latest chipset designed to support dual-
channel DDR3 1600 / 1333 / 1066 / 800 architecture, 1600 / 1333 / 1066 / 800 FSB
(Front Side Bus), dual PCI Express x16 graphics and multi-core CPUs. It especially
includes Intel
®
Fast Memory Access technology that signicantly optimizes the use
of available memory bandwidth and reduces the latency of the memory accesses.
PCIe 2.0
This motherboard supports the latest PCIe 2.0 device for twice the current speed
and bandwidth. This enhances system performance while still providing backward
compatibility to PCIe 1.0 devices.
DDR3 memory support
The motherboard supports DDR3 memory that features data transfer rates
of 1800(O.C.) / 1600 / 1333 / 1066 / 800 MHz to meet the higher bandwidth
requirements of the latest 3D graphics, multimedia, and Internet applications. The
dual-channel DDR3 architecture doubles the bandwidth of your system memory
to boost system performance. Furthermore, this motherboard does not restrict the
memory size across two channels. Users may install different memory size DIMMs
into the two channels and enjoy dual-channel and single-channel functions at the
same time. This new feature optimizes the use of available memory size. See page
2-13 for details.
