It features dual-channel DDR2 1066 memory support and accelerates data transfer rate up to 5200MT/s via HyperTransport™ 3.0 based system bus.

AMD® Socket AM2 Athlon™/Sempron™ CPU Support

This motherboard supports AMD® Socket AM2 Athlon™/Sempron™ processors. It features 2000/1600 MT/s HyperTransport™-based system bus, dual-channel un-buffered DDR2 800 memory support, and AMD® Cool ´n´ Quiet™ Technology.

Native DDR2 1066

This motherboard supports native DDR2 1066. It provides faster data transfer rate and more bandwidth to increase memory data transfer rate and computing efficiency, enhancing system performance in 3D graphics and other memory demanding applications.
*DDR2 1066 is supported by some of the AM2+ CPUs only. Refer to www.asus.com for the supported CPU models.

HyperTransport 3.0 Support

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

AMD Cool ´n´ Quiet! Technology

M3A78 supports AMD Cool 'n' Quiet! Technology, which monitors system operation and automatically adjusts CPU voltage and frequency for a cool and quiet environment.

Dual-Core CPU

Enjoy the extraordinary CPU power from the latest dual-core CPU. The advanced processing technology contains two physical CPU cores with individually dedicated L2 cache to satisfy the rising demand for more powerful processing capability.

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 supporting either 64-bit or 32-bit architecture.

PCI Express Architecture

PCI Express is the latest I/O interconnect technology that 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.

PCIe 2.0 support

This motherboard supports the latest PCIe 2.0 devices for double speed and bandwidth which enhances system performance.

Serial ATA 3Gb/s

This motherboard supports next-generation SATA hard drives based on the new SATA 3Gb/s storage specification. The onboard SB700 southbridge allows RAID 0, RAID 1,RAID 10 configurations for six SATA connectors.

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.

High Definition Audio

Enjoy high-quality 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-detect feature,which automatically detects and identifies what types of peripherals are plugged into the audio I/O jacks and notifies users of inappropriate connection, meaning there will be no more confusion of Line-in, Line-out and Mic jacks.

ASUS Q-Fan

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

Max. 10 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.

Express Gate

Instant Internet Access without Entering Windows!
With only 5 seconds boot-up time, the ASUS Express Gate allows you to instantly surf the Internet without entering Windows or the Hard Disk. You can now enjoy Skype, IM, YouTube, webmail and internet file downloads and sharing whenever and wherever you want!
* The actual boot time is subject to hardware configurations and product models.

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.

ASUS EZ Flash2

With ASUS EZ Flash, you can update BIOS before entering operating system. No more DOS-based flash utility and bootable diskette required.

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.

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.

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.
