This motherboard supports AMD AM3 multi-core processors with unique L3 cache & delivers better overclocking capabilities with less power consumption. It features dual-channel DDR3 1333 memory support & accelerates data transfer rate up to 5200MT/s via Hyper Transport 3.0 based system bus. This motherboard also supports AMD CPUs in the 45nm manufacturing process. NVIDIA n Force 750a SLI media & communications processors (MCPs) are the foundation for the worlds ultimate gaming PC. It supports the NVIDIA Scalable Link Interface (SLI) technology that allows two graphics processing units (GPUs) in a single system. The NVIDIA n FORCE 750a SLI chipset also supports six (6) Serial ATA 3 Gb/s devices, PCI Express x 16 slots with NVIDIA SLI support at dual x 8 mode, & up to 12 USB (Universal Serial Bus) 2.0 ports. NVIDIA SLI (Scalable Link Interface) makes use of the PCI Express 2.0 bus architectures increased bandwidth & features intelligent hardware & software that allows two GPUs to efficiently work together to deliver earth-shattering, scalable performance. For some applications, this translates into nearly double the performance! This motherboard supports the PCIe 2.0 devices for double speed & bandwidth which enhances system performance. Hyper Transport 3.0 technology provides 2.6 times more bandwidth than Hyper Transport 1.0, radically improving system efficiency to create a smoother, faster computing environment. This motherboard supports DDR3 2000 (O.C.) that provides faster data transfer rate & more bandwith to increase memory computing efficiency, enhancing system performance in 3D graphics & other memory demanding applications. Hybrid SLI technology is a unique hybrid multi-GPU technology. It turbo-charges performance of discrete graphics cards when combined with the motherboard GPUs. To fully unleash the AM3 CPUs potential, the ASUS M4 Series motherboards have adopted a 8-phase VRM power design. It delivers high power efficiency & supreme overclockin
