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 1333 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. NVIDIA nForce 750a SLI media and communications processors (MCPs) are the foundation for the world's 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 nFORCE 750a SLI chipset also supports six (6) Serial ATA 3 Gb/s devices, PCI Express x16 slots with NVIDIA SLI support at dual x8 mode, and up to 12 USB 2.0 ports. NVIDIA SLI (Scalable Link Interface) makes use of the PCI Express 2.0 bus architecture's increased bandwidth and features intelligent hardware and 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 and bandwidth which enhances system performance. 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. This motherboard supports DDR3 2000(O.C.) that provides faster data transfer rate and more bandwith to increase memory computing efficiency, enhancing system performance in 3D graphics and 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 CPU's potential, the ASUS M4 Series motherboards have adopted a 8-phase VRM power design. It delivers high power efficiency and supreme overclocking ability. Furthermore, high quality power components can effectively lower system temperature to ensure longer component lifespan. This series also features an extra 1 phase power dedicated to integrated memory/HT controller. This motherboard uses all long-life capacitors onboard for durability, improved lifespan, and enhanced thermal capacity. The ASUS EPU (Energy Processing Unit) provides total system power management by detecting current PC loadings and intelligently moderating power in real-time. It automatically provides the most appropriate power usage for the CPU, VGA card, hard drives, and CPU/chassis fans- helping save power and money! ASUS Core Unlocker simplifies the activation of a latent AMD CPU with just a simple switch or hot key. Enjoy an instant performance boost by simply unlocking the extra cores, without performing complicated BIOS changes.
