Enhanced Intel SpeedStep¨ Technology (EIST)

The Enhanced Intel SpeedStep¨ Technology (EIST) intelligently manages the CPU resources by automatically adjusting the CPU voltage and core frequency depending on the CPU loading and system speed or power requirement.

See page 2-22 and the Appendix for details.

Intel¨ 915G

The Intel¨ 915G graphics memory controller hub (GMCH) and the ICH6 I/O controller hub provide the vital interfaces for the motherboard. The GMCH features the Intel¨ Graphics Media Accelerator 900, an integrated graphics engine for enhanced 3D, 2D, and video capabilities. The GMCH provides the interface for a processor in the 775-land package with 533/800 MHz front side bus (FSB), dual channel DDR at speeds of up to 400 MHz, and PCI Express x16 interface for a graphics card.

The Intel¨ ICH6 Southbridge represents the sixth generation I/O controller hub that provides the interface for PCI Express and 8-channel high definition audio.

Dual display technology support (optional)

The integrated graphics engine supports dual display technology and TV out function through the optional ASUS DVI-ADD2 card. You can show additional independent display on an LCD monitor, or stretch one type of content on both VGA and LCD monitors for more workspace. See page 1-20 for details.

Dual-channel DDR memory support

Employing the Double Data Rate (DDR) memory technology, the motherboard supports up to 4 GB of system memory using DDR 400/333 DIMMs. The ultra-fast 400 MHz memory bus delivers the required bandwidth for the latest 3D graphics, multimedia, and Internet applications. See page 1-14 for details.

PCI Expressª interface

The motherboard fully supports PCI Express, the latest I/O interconnect technology that speeds up the PCI bus. PCI Express features point-to-point serial interconnections between devices and allows higher clockspeeds by carrying data in packets. This high speed interface is software compatible with existing PCI specifications. See page 1-20 for details.

Serial ATA technology

The motherboard supports the Serial ATA technology through the Serial ATA interfaces and the Intel¨ ICH6. The SATA specification allows for thinner, more flexible cables with lower pin count, reduced voltage requirement, and up to 150 MB/s data transfer rate. See page 1-27 for details.
