P5 Ai Proactive Series - Intel 915G chipset-Intel LGA775 Pentium 4 CPU-Dual-Channel DDR 400-PCI Express Architecture-Powerful Integrated Graphics-Max. 8 USB 2.0 ports supports-ASUS Q-Fan Technology-ASUS CrashFree BIOS2 Shop Modal header CPU Chipset SATA FSB LAN USB 2.0 1394 DDR P4 LGA775 915G 4 800 10/100 8 0 400(Dual channel) 64bit CPU support 64-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. Intel EM64T Intel EM64T (Intel Extended Memory 64 Technology) allows processors to run newly written 64-bit code and to access larger amounts of memory, which delivers exceptional graphic performance and higher data processing speed. Digital media applications can take advantage of Intel EM64T in high quality video and audio processing as well as 3D rendering. Intel EIST Intel EIST (Enhanced Intel SpeedStep technology) automatically adjusts Intel 64-bit processor voltage and core frequency according to system performance demand, establishing a self-managed, lower-power consumption, less heat and quieter environment. Combined Intel EIST and ASUS Q-fan technology (adjusts fan speeds according to system loading), this motherboard provides excellently quiet, cool and efficient platform for Intel lovers. Intel 915G ChipsetThe Intel 915G chipset supports the latest PC technologies such as LGA775 Pentium 4 CPU, dual-channel DDR memory architecture, and PCI Express x16 graphics card interface. Intel Graphics Media Accelerator 900 provides a significant increase in graphics performance. The ICH6 Southbridge further provides PCI Express x1 interfaces and 8 high-speed USB 2.0 ports. ports. Intel LGA775 Pentium 4 CPUThis motherboard supports the latest Pentium 4 CPU from Intel in LGA775 package. With 800MHz FSB, MB L2 cache, Hyper-Threading Technology and core-speeds up to 3.6GHz and beyond, Intel's LGA775 Pentium 4 is one of the fastest desktop processors to date."Attention!! CPU Installation" Dual-channel DDRDual-channel DDR technology doubles the bandwidth of your system memory and hence boost the system performance to out perform any memory existing solutions in the market. System bottlenecks are eliminated with balanced architecture and peak bandwidths up . Powerful Integrated GraphicsThe new Intel Graphics engine has new capabilities that provide a significant increase in graphics performance. DirectX 9 hardware acceleration, 333MHz core clock, and large video memory all together provide a full-value, high performance graphic PCI Express ArchitecturePCI 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. The high speed PCI Express interface creates new usages on desktop PCs e.g., Gigabit LAN, 1394b, and high-speed RAID systems. High Definition Audio Enjoy high-end sound system on your PC! The onboard 8-channel HD audio (High Definition Audio, previously codenamed Azalia) CODEC enables high-quality 192KHz/24-bit audio output, jack-sensing feature and retasking functions. With the 8-channel audio ports and S/PDIF out interface, you can connect your computer to home theater decoders to produce crystal-clear digital audio. Max. 8 USB 2.0 ports supportsUSB 2.0 is the latest connectivity standard for next generation components and peripherals. Backwards compatible with current USB 1.1 peripherals, USB 2.0 delivers transfer speeds up to 40 times faster at 480Mb/s, for easy connectivity and ultra-fast data transfers. 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.
