This motherboard supports the latest Intel Core i7 processors in LGA1366 package with integrated memory controller to support 3-channel (6 DIMMs) DDR3 memory. Supports Intel QuickPath Interconnect (QPI) with a system bus of up to 6.4 GT/s and a max bandwidth of up to 25.6 GB/s. Intel Core i7 processor is one of the most powerful and energy efficient CPUs in the world. The Intel X58 Express Chipset is one of the most powerful chipset designed to support the Intel Core i7 Processors with LGA1366 package and Intel next generation system interconnect interface, Intel QuickPath Interconnect (QPI), providing improved performance by utilizing serial point-to-point links, allowing increased bandwidth and stability. It also supports up to 36 PCI Express 2.0 lanes providing better graphics performance. The P6X58D-E breaks the boundaries to bring you the multi-GPU choice of either SLI or CrossFireX. The motherboard features a dedicated graphics engine on the most powerful Intel X58 platform to optimize PCIe allocation in multiple GPU configurations. Expect a brand-new gaming style you've never experienced before! This motherboard supports the latest PCIe 2.0 devices for double speed and bandwidth which enhances system performance. Supporting next-generation Serial ATA (SATA) storage interface, this motherboard delivers up to 6.0Gb/s data transfer rates. Additionally, get enhanced scalability, faster data retrieval, double the bandwidth of current bus systems. Experience ultra-fast data transfers at 4.8Gbps with USB 3.0 - the latest connectivity standard. Built to connect easily with next generation components and peripherals, USB 3.0 transfers data 10X faster and is also backward compatible with USB 2.0 components. The motherboard supports DDR3 memory that features data transfer rates of 2000(O.C.) / 1333 / 1066 MHz to meet the higher bandwidth requirements of the latest 3D graphics, multimedia, and Internet applications. The triple-channel DDR3 architecture enlarges the bandwidth of your system memory to boost system performance. The groundbreaking 16+2 phase VRM design is brrought to the ASUS motherboards. 16+2 phase power design, 16-phase for vCore and extra 2-phase for QPI/Memory controller inside CPU, can provide the highest power efficiency, and hence generates less heat to effectively enhance the overclocking capability. With the high quality power components such as low RDS (on) MOSFETs, Ferrite core chokes with lower hysteresis loss and 100% high quality conductive polymer capacitors, ASUS 16+2 phase VRM design also ensure longer component life and minimum power loss. Feel the adrenaline rush of real-time OC - now a reality with the ASUS TurboV. This extreme OC tool lets you set new ambitions on the OC stage with an advanced and easy-to-use interface - allowing you to overclock without exiting or rebooting the OS. With micro adjustments of the CPU PLL, NB, NB-PCIe, and DRAM voltages in 0.02v intervals, there are no limits - only extreme results to break new OC records! The ASUS EPU - the world's first power saving engine, has been upgraded to a six engine version, which provides total system power savings by detecting current PC loadings and intelligently moderating power in real-time. With auto phase switching for components (which includes the CPU, VGA card, memory, chipset, drives and system fan), the EPU automatically provides the most appropriate power usage via intelligent acceleration and overclocking - helping save power and money.
