With 1066o.c/800/ 533MHz FSB, Hyper-Threading Technology and core-speeds up to 3.8GHz and beyond. Intel Core™2 Duo This motherboard supports the latest Intel® Core™2 processors in LGA775 package. With new Intel® Core™ microarchitecture technology and 1066O.C/800 MHz FSB, Intel® Core™2 processor is one of the most powerful and energy efficient CPUs in the world.Intel® 65nm Dual-Core CPU support This motherboard supports Intel® Pentium® D/Pentium® 4/Celeron D® 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. 64-bit CPU support 64-bit computing, the technology to replace 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™ Architecture The 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 CrashFree BIOS 2 The 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. EZ-Flash With ASUS EZ Flash, you can update BIOS before entering operating system. No more DOS-based flash utility and bootable diskette required. ASUS Q-Fan ASUS 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. Serial ATA 3Gb/s The motherboard supports the 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 Audio Enjoy 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-out This motherboard provides convenient connectivity to external home theater audio systems via coaxial and optical S/PDIF-out (SONY-PHILIPS Digital Interface) jacks. It allows to transfer digital audio without converting to analog format and keeps the best signal quality.
