The motherboard supports AMD AM2+/AM2 for Phenom FX/Phenom/Athlon 64/ Sempron/Athlon 64 X2/ Athlon 64 FX/ processors and compatible with Phenom™ II/ Athlon™ X4/ Athlon™ X3/ Athlon™ X2 (AM3 CPU)with 2MB / 1MB / 512KB L2 cache, which is based on 64-bit architecture. It features 5200 MT/s HyperTransport3.0 Bus, dual-channel un-buffered DDR2 1066 memory support and AMD Cool ´n´ Quiet! 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.
HyperTransport 3.0 Support
Provides 2.6 times more bandwidth than HT1.0 that radically improves system efficiency for a smoother, faster computing environment.
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.
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.
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.
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.
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.
