P9D-X xxS2xxxxxxxx Made in China 合格 1.4 Special features 1.4.1 Product highlights Latest processor technology This motherboard supports the latest Intel® Xeon® Processor E3-1200 v3/ CoreTM i3 series in LGA1150 package, which has memory and PCI Express controller integrated to support 2-channel (4 DIMMs) DDR3 memory and 16 PCI Express 3.0 lanes. The Intel® Xeon® E3-1200 v3 have improve CPU performance and integrated voltage regulators making it one of the most powerful and energy efficient CPU in the world. Intel® Turbo Boost Intel® Turbo Boost automatically allows the processor to run faster than the marked frequency if the processor is operating below its power, current, and temperature specification limits. This technology increases performance of both multi-threaded and single-threaded workloads. Intel® Hyper Threading The thread-level parallelism on each processor makes more efficient use of the processor resources, higher processing throughout and improved performance on today's multithreaded software. Intel® EM64T The motherboard supports Intel® processors with the Intel® EM64T (Extended Memory 64 Technology). The Intel® EM64T feature allows your computer to run on 64-bit operating systems and access larger amounts of system memory for faster and more efficient computing. DDR3 memory support The motherboard supports ECC UDIMM DDR3 memory that features data transfer rates of 1600/1333 MHz to meet the higher bandwidth requirements of server and workstation applications. The dual-channel DDR3 architecture boosts system performance, eliminates bottlenecks with peak bandwidth up to 25Gb/s, and dramatically reduces the memory voltage to just 1.5V compared to DDR2's memory voltage of 1.8V. 1-4 Chapter 1: Product introduction
