Dual channel 4 DDR3 1800+ (O.C.)HDMI/DVI/RGB Interface SupportASUS EPUAnti-Surge ProtectionTurbo Key Shop Modal header Phenom™ II/Athlon™ II/Sempron™ 100 Series Processors(Socket AM3) 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 new 45nm manufacturing process. HyperTransport 3.0 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. Dual-Channel DDR3 1800(O.C.) 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. The dual-channel DDR3 architecture doubles the bandwidth of your system memory to boost system performance, eliminating bottlenecks with peak bandwidths of up to 25.6 GB/s. Furthermore, the supply voltage for the memory is reduced from 1.8 V for DDR2 to just 1.5 V for DDR3. This voltage reduction limits the power consumption and heat generation of DDR3 which makes it an ideal memory solution. Hybrid CrossfireX Boosted Performance with onboard GPUand discrete graphics card 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 (For Windows Vista or later versions). HDMI Support Enjoy Full HD 1080p Multimedia Home-Theater EntertainmentHigh-Definition Multimedia Interface (HDMI) is a set of digital video standards that delivers multi-channel audio and uncompressed digital video for full HD 1080p visuals through a single cable. Supporting HDCP copy protection such as HD DVD and Blu-ray Discs, HDMI provides you with the highest-quality home theater experience. 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. 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.It also supports RAID0, RAID1,RAID 0+1 and JBOD Configurations for SATA hard drives. USB 2.0 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. Gigabit Lan This capability ensures rapid transfer of data from WAN to LAN without any added arbitration or latency. AMD Cool ´n´ Quiet! Technology M4A78LT-M supports AMD Cool ´n´ Quiet!
