Intel LGA775 CPUThis motherboard supports the latest Pentium 4 CPU from Intel in LGA775 package. With 1066/ 800/ 533MHz FSB, Hyper-Threading Technology and core-speeds up to 3.8GHz and beyond. Intel® 65nm Dual-Core CPU supportThis motherboard supports Intel® Pentium® D/Pentium® 4/Celeron® dual-core processors built on the 65-nanometer (nm) process technology with copper interconnect. Dual-core processors contain two physical CPU cores with dedicated L2 caches to meet demands for more powerful processing. Intel®'s 65nm process is the most advanced chip manufacturing technology, delivering breakthrough performance, enhanced media experience, and low power consumption. Intel® 65nm dual-core processors utilize the latest package technologies for a thinner, lighter design without compromising performance. 64-bit CPU support64-bit computing, the next generation technology to replace current 32-bit architecture, delivers advanced system performance, faster memory access and increased productivity. This motherboard provides excellent compatibility and flexibility by supporting either 64-bit or 32-bit architecture. SIS Advanced HyperStreaming™ ArchitectureThe motherboard supports the SIS HyperStreaming™ technology that smartly manages data streaming between the Northbridge and Southbridge, memory, graphics interface, and other peripherals for efficient and superior performance. Asus Unique Features ASUS CrashFree BIOS2The CrashFree BIOS2 feature now includes the BIOS auto-recovery function in a support CD. Users can reboot their system through the support CD when a bootable disk is not available, and go through the simple BIOS auto-recovery process. ASUS motherboards now enable users to enjoy this protection feature without the need to pay for an optional ROM. ASUS EZ FlashWith ASUS EZ Flash, you can update BIOS before entering operating system. No more DOS-based flash utility and bootable diskette required. ASUS Q-FanASUS Q-Fan technology intelligently and automatically adjusts CPU fan speeds according to system load and temperature, enabling users to work in a distraction-free environment with minimal noise. Other Features 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 also outperforms PCI interface with its exceptional high bandwidth up to 500MB/s. Universal PCI-E SlotThe Universal PCI Express technology offers utilization flexibility of the Southbridge PCI Express interface. It enables users to plug in an additional PCI Express graphics card to set up a dual graphics card platform on a single motherboard. ASUS’ own smart quick switch further detects how users installed their PCI Express devices, and intelligently reroutes the PCI Express lanes for optimized bandwidth allocation. Serial ATA 3Gb/sThe motherboard supports the next-generation hard drives based on the Serial ATA (SATA) 3Gb/s storage specification, delivering enhanced scalability and doubling the bus bandwidth for high-speed data retrieval and saves. High Definition AudioEnjoy six-end sound system on your PC! The onboard 6-channel HD audio (High Definition Audio, previously codenamed Azalia) CODEC enables high-quality 192KHz/24-bit audio output, jack-sensing feature. S/PDIF-outThis motherboard provides convenient connectivity to external home theater audio systems via an 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. Gigabit LAN Attansic F1 PHY delivers transfer speeds up to ten times faster than conventional 10/100 Ethernet connections. Gigabit LAN is the networking standard for the early future and is ideal for handling large amounts of data such as video, audio, and voice.
