Intel LGA775 Platform Intel G31/ICH7 Chipset FSB 1600(O.C.)/1333/1066/800 DDR2 1066(O.C.)/800/667 ASUS EPU Shop Modal header LGA775 Intel® 45nm Processor Ready This motherboard supports the latest Intel 45nm CPU which introduces new micro-architecture features for greater performance at a given frequency, up to 50% larger L2 caches, and expanded power management capabilities for new levels of energy efficiency. LGA775 Intel® Core™2 Processor This motherboard supports the latest Intel® Core™2 processors in LGA775 package. With new Intel® Core™ microarchitecture technology and 1600(O.C.)/1333/1066/800 MHz Intel® Core™2 processor is one of the most powerful and energy efficient CPU in the world. Dual-Channel DDR2 1066(O.C.) DDR2 1066(O.C.) memory provides great performance for 3D graphics and other memory demanding applications on next generation memory technology. PCI Express Architecture PCI Express is the latest I/O interconnect technology that will replace the existing PCI. With a bus bandwidth 4 times higher than that of AGP 8X interface, PCI Express x16 bus performs much better than AGP 8X in applications such as 3D gaming. PCI Express x1 and x4 also outperforms PCI interface with its exceptional high bandwidth. The high speed PCI Express interface creates new usages on desktop PCs. SATA 3Gb/s Serial ATA3.0Gb/s is the next generation ATA specification that provides scalable performance for today and tomorrow. With up to 300MB/s data transfer rate, Serial ATA II is faster than current Parallel ATA, while providing 100% software compatibility. EPU The ASUS EPU (Energy Processing Unit) provides total system power management by detecting current PC loadings and intelligently moderating power in real-time. It automatically provides the most appropriate power usage for the CPU, VGA card, hard drives, and CPU/chassis fans- helping save power and money! High Definition Audio Enjoy high-quality sound system on your PC! The onboard 8-channel HD audio (High Definition Audio, previously codenamed Azalia) CODEC enables high-quality audio output, jack-detect feature automatically. S/PDIF-out on Back I/O Port This motherboard provides convenient connectivity to external home theater audio systems via an optical or coaxial S/PDIF-out (SONY-PHILIPS Digital Interface) jack. It allows to transfer digital audio without converting to analog format and keeps the best signal quality. ASUS Express Gate 0 to Internet in Seconds!Express Gate™ is an ASUS exclusive OS that provides you with quick access to the Internet and key applications before entering Windows®. ASUS AI NET2 Diagnose LAN connection before entering OS! Network problems are often caused by bad cable connection. AI NET2 remotely detects cable connection the second you turn on the system, and any faulty connections are reported back up to 100 meters at 1 meter accuracy. Gigabit Lan With Intel CSA-based Gigabit LAN controller, network data can be transferred at a much higher rate with lower latency. This new interface performs networking tasks more efficiently, and achieves bi-directional gigabit speeds. ASUS Q-Fan ASUS Q-Fan technology intelligently adjusts CPU fan speeds according to system loading to ensure quiet, cool and efficient operation. C.P.R.(CPU Parameter Recall) When the system hangs due to overclocking failure, there is no need to open the case to clear CMOS data. Just simply restart the system, the BIOS would show the previous setting and then users can amend the CPU setting again. EZ Flash2 Simply update BIOS from a USB flash disk before entering the OSEZ Flash is a user-friendly BIOS update utility. Simply press the pre-defined hotkey to launch this tool and update BIOS from a floppy disk before entering the OS. CrashFree BIOS 3 Simply restore corrupted BIOS data from USB flash diskThe ASUS CrashFree BIOS 3 allows users to restore corrupted BIOS data from a USB flash disk containing the BIOS file. This utility saves users the cost and hassle of buying a replacement BIOS chip. MyLogo2 Personalize your system with customizable boot logoYou can convert your favorite photo into a 256-color boot logo for a more colorful and vivid image on your screen. Compliance with the RoHS Directive The 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 and packaging to safeguard consumers´ health while minimizing the impact on the environment.
