      AMD® Phenom™ X4/ Phenom™ X3/ Athlon™ X2/ Athlon™/ Sempron™ processors (socket AM2+/AM2)

      This motherboard supports AMD® Socket AM2+ multi-core processors. It features dual-channel DDR2 1066 memory support, data transfer rate up to 5200MT/s via HyperTransport™ 3.0 based system bus, and AMD® Cool ´n´ QuietTM Technology.

      O.C. DDR2 1200

      To attain top performance, ASUS engineers have successfully unleashed DDR2 1200(O.C.) MHz to meet the higher bandwidth requirements of the latest operation system, 3D graphics, multimedia, and Internet applications.

      *Ensure that you download and update to the latest BIOS at www.asus.com and purchase the memory modules listed in the ASUS official memory Qualified Vendors Lists (QVL).
      ** We recommend that you install the DDR2 1200 memory modules on the yellow slots for better performance.

      64-bit CPU support

      64-bit computing, the next generation technology to replace the current 32-bit architecture, delivers advanced system performance, faster memory access and increased productivity. This motherboard provides excellent compatibility and flexibility by support Intel EM64T.

      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 in applications such as 3D gaming.

      HyperTransport 3.0 Support

      Provides 2.6 times more bandwidth than HT1.0 that radically improves system efficiency for a smoother, faster computing environment.

      Serial ATA 3Gb/s

      This motherboard supports next-generation SATA hard drives based on the new SATA 3Gb/s storage specification, allowing RAID 0, RAID 1,RAID 0+1 and JBOD configurations for five SATA connectors.

      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.

      SATA on the Go

      The 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. The external SATA port located at the back I/O provides smart setup and hot-plug functions. Easily backup photos, videos and other entertainment contents on external devices.

      Gigbit LAN

      The on-board LAN controller is a highly integrated GbLAN controller. It is enhanced with an ACPI management function to provide efficient power management for advanced operating systems.

      ASUS CrashFree BIOS3

      The 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.

      S/PDIF-out on Back I/O Port

      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.

      AMD Cool ´n´ Quiet! Technology

      M4A78 supports AMD Cool ´n´ Quiet! Technology, which monitors system operation and automatically adjusts CPU voltage and frequency for a cool and quiet environment.

      ASUS Q-Fan

      ASUS Q-Fan technology intelligently adjusts CPU fan speeds according to system loading to ensure quiet, cool and efficient operation.

      Max. 12 USB 2.0 ports

      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.

      Turbo Key

      ASUS Turbo Key allows the user to turn the PC power button into an overclocking button. After the easy setup, Turbo Key can boost performances without interrupting ongoing work or games - with just one touch!!

      ASUS EZ Flash2

      EZ Flash 2 is a user-friendly BIOS update utility. Simply launch this tool and update BIOS from a USB flash disk before entering the OS. You can update your BIOS only in a few clicks without preparing an additional floppy diskette or using an OS-based flash utility.

      MyLogo2

      Personalize your system with customizable boot logo
      You can convert your favorite photo into a 256-color boot logo for a more colorful and vivid image on your screen.

      AI Nap

      With AI Nap, the system can continue running at minimum power and noise when you are temporarily away. To wake the system and return to the OS environment, simply click the mouse or press a key.

      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!

      GreenASUS

      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.
