This motherboard supports AMD AM3 multi-core processors with unique L3 cache and delivers better overclocking capabilities with less power consumption. It features dual-channel DDR3 memory support and accelerates data transfer rate up to 5200MT/s via HyperTransport 3.0 based system bus. This motherboard also supports AMD CPUs in the 45nm manufacturing process. HyperTransport 3.0 technology provides 2.6 times more bandwidth than HyperTransport 1.0, radically improving system efficiency to create a smoother, faster computing environment. ATI Hybrid CrossFireX technology is a unique hybrid multi-GPU technology. It takes your gaming experience to the next level boosting PC performance by enabling the chipset’s integrated graphics processor and a discrete GPU to operate simultaneously with combined output for blisteringly-fast frame rates unleashing the graphics performance. This motherboard supports multiple digital and analog display output interfaces -DVI, and D-Sub. With such diversity of display outputs, you are able to choose and upgrade display devices freely. DVI (Digital Visual Interface) provides high visual quality of digital display devices such as LCD monitor. The interface of this motherboard supports dual VGA output both DVI and RGB and is HDCP compliant allowing playback of HD DVD, Blu-ray Disc and other protected content. The motherboard supports DDR3 memory that features data transfer rates of 1800 (O.C.)/1600(O.C.)/1333/1066 MHz to meet the higher bandwidth requirements of the latest operation system, 3D graphics, multimedia, and Internet applications. 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. This motherboard supports next-generation SATA hard drives based on the SATA 3Gb/s storage specification. It also supports RAID0, RAID1, RAID 0+1 configurations for SATA hard drives. USB 2.0 is the latest connectivity standard for next generation components and peripherals. Backwards compatible with 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. This capability ensures rapid transfer of data from WAN to LAN without any added arbitration or latency. ASUS Q-Fan technology intelligently adjusts CPU fan speeds according to system loading to ensure quiet, cool and efficient operation. M4A78LT-M LE supports AMD Cool ‘n’ Quiet! technology, which monitors system operation and automatically adjusts CPU voltage and frequency for a cool and quiet environment. The ASUS EPU – the world’s first power saving engine, has been upgraded to a 4-engine version, which provides total system power savings by detecting current PC loadings and intelligently moderating power in real-time. The EPU automatically provides the most appropriate power usage for the CPU, VGA card, hard drives and CPU cooler fan – helping save power and money. ASUS Turbo Key allows the user to turn the PC power button into a physical overclocking button. After the easy setup, Turbo Key can boost performances without interrupting ongoing work or games – with just one touch! Express Gate is an ASUS exclusive OS that provides you with quick access to the Internet and key applications before entering Windows.
