      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.

      DDR2 711 Native Support

      Although Intel's 925XE chipsets claimed to only support DDR2 400/533, ASUS engineers successfully unleashed their true potential. This model offers native DDR2 711, eliminating the bottleneck when overclocking both the CPU and memory. With current processors supporting 1066MHz FSB, ASUS motherboards, the only solutions with native DDR2 711, will provide superior performance for the most demanding applications.

      Hyper Path2 - Shorten Memory Latency
      The innovative ASUS Hyper Path2 significantly shortens the latency time between the CPU and memory on 925XE chipsets and improves memory performance without sacrificing stability. Enabling both Hyper Path2 and Intel PAT (Performance Acceleration Technology) on the ASUS 925XE based motherboards, delivers powerful computing never seen before.

      The highest C/P value in 2005 with Intel 925XE chipset inside.

      The P5AD2-E is one of the most comprehensive ASUS AI Proactive series motherboards. Featuring RAID systems, gigabit Ethernet LAN, and the most advanced PC technologies from the Intel 925XE chipsets and lower pricing than the other performance model the P5AD2-E gets the highest C/P value. With its unsurpassed performance, the P5AD2-E also works perfectly as a high-end gaming machine or a task-intensive workstation.

      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 925XE chipset
      Its PAT (performance acceleration technology) function boosts the system performance without sacrificing any system stability. Companioned with the ICH6R Southbridge chip to provide integrated 4-port SATA RAID controller, PCI Express x1 interfaces and 8 high-speed USB 2.0 ports, the Intel 925XE chipset is the best solution for high-end desktop system.

      Intel LGA775 Pentium 4 CPU
      This motherboard supports the latest Pentium 4 CPU from Intel in LGA775 package. With 800MHz FSB, 1 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 DDR2 533
      DDR2 is the next generation memory technology to replace the current DDR. With initial speeds from 400 and 533MHz, DDR2 memory provides bandwidth up to 4.3GB/s. Doubled by the dual-channel architecture, the widest memory bus bandwidth 8.6GB/s is achieved on this motherboard.

      Intel PAT
      The Intel Performance Acceleration Technology (Intel PAT) delivers additional system-level performance by optimizing memory access between CPU and system memory, and allows increased performance at standard operating specifications.

      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. The high speed PCI Express interface creates new usages on desktop PCs e.g., Gigabit LAN, 1394b, and high-speed RAID systems.

      AI Proactive

      AI NOS™
      Boost performance when you need it the most!

      Applications such as 3D games and video editing demand a huge chunk of system resource.
      Inject "nitrous oxide" into your CPU! The patented AI NOS™ (Non-delay Overclocking System) technology intelligently detects system load and automatically boosts performance for the most demanding tasks. Unlike other dynamic overclocking techniques, AI NOS™ reacts much faster to satisfy your unending need for speeds.

      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.

      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, retasking functions and multi-streaming technology that simultaneously sends different audio streams to different destinations. You can now talk to your partners on the headphone while playing a multi-channel network games. All of these are done on one computer. The Dolby Digital Live technology from Dolby Lab encodes the multi-channel audio source into AC-3 bit-stream and outputs it to S/PDIF port in real time.

      Serial ATA
      Serial ATA is the next generation ATA specification that provides scalable performance for today and tomorrow. With up to 150MB/s data transfer rate, Serial ATA is faster than current Parallel ATA, while providing 100% software compatibility.

      USB 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 BIOS2
      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.

      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.
