The motherboard delivers a host of new features and latest technologies, making it another standout in the long line of ASUS quality motherboards! Before you start installing the motherboard, and hardware devices on it, check the items in your package with the list below. 1.2 Package contents Check your motherboard package for the following items.
1.3 Special features 1.3.1 Product highlights Latest processor technology The motherboard comes with a 775-pin surface mount Land Grid Array (LGA) socket designed for the Intel® Pentium® 4 or Intel® Celeron® processor in the 775-land package. The motherboard supports the Intel® Pentium® 4 processor with 800/533 MHz Front Side Bus (FSB). The motherboard also supports the Intel® Hyper-Threading Technology and is fully compatible with Intel® 04B and 04A processors. See page 1-9 for details.
Dual-channel DDR memory support Employing the Double Data Rate (DDR) memory technology, the motherboard supports up to 4GB of system memory using DDR400/333 DIMMs. The ultra-fast 400MHz memory bus delivers the required bandwidth for the latest 3D graphics, multimedia, and Internet applications. See page 1-16 for details. PCI Express™ interface (max 2GB/s transfer rate, x4 mode) The motherboard fully supports PCI Express, the latest I/O interconnect technology that speeds up the PCI bus.
USB 2.0 technology The motherboard implements the Universal Serial Bus (USB) 2.0 specification, dramatically increasing the connection speed from the 12 Mbps bandwidth on USB 1.1 to a fast 480 Mbps on USB 2.0. USB 2.0 is backward compatible with USB 1.1. See pages 1-24, 1-27, 1-30 and 2-21 for details. Temperature, fan, and voltage monitoring The CPU temperature is monitored by the Winbond Super I/O to prevent overheating and damage.
1.4 Before you proceed Take note of the following precautions before you install motherboard components or change any motherboard settings. • Unplug the power cord from the wall socket before touching any component. • Use a grounded wrist strap or touch a safely grounded object or to a metal object, such as the power supply case, before handling components to avoid damaging them due to static electricity • Hold components by the edges to avoid touching the ICs on them.
1.5 Motherboard overview Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it. Make sure to unplug the power cord before installing or removing the motherboard. -ure to do so can cause you physical injury and damage motherboard components. 1.5.1 Placement direction When installing the motherboard, make sure that you place it into the chassis in the correct orientation.
