Built upon the functionality and the capability of the Intel 5520 platform, the X8DA3/X8DAi motherboard provides the performance and feature set required for dual-processor-basedhigh-end systems with configuration options optimized for workstations, high-end CAD systems, and intensive applications. The 5500 Series Processor platform consists of the 5500 Series Processor (LGA 1366) processor, the 5200 (North Bridge), and the ICH10R (South Bridge). With the Intel QuickPath interconnect controller built in the processor, the 5500 Series Processor platform is the first dual-processing platform to offer the next generation point-to-point system interconnect interface, replacing the current Front Side Bus Technology, providing substantial system performance enhancement by utilizing serial link interconnec- tions, allowing for increased bandwidth and scalability.
The IOH connects to each processor through an independent QuickPath Inter- connect link. Each link consists of 20 pairs of unidirectional differential lanes for transmission and receiving in addition to a differential forwarded clock. A full-width QuickPath interconnect link pair provides 84 signals. Each processor supports two QuickPath link, one going to the other processor and the other to the 5520 chip.
The Intel 5520 platform supports up to 36 PCI Express Gen2 lanes, and the 5520 North Bridge supports peer-to-peer read and write transactions. The ICH10R pro- vides up to 6 PCI-Express ports, six SATA ports and 10 USB connections.
In addition, the Intel 5520 platform also offers a wide range of RAS (Reliability, Availability and Serviceability) features. These features include memory interface ECC, x4/x8 Single Device Data Correction (SDDC), Cyclic Redundancy Check (CRC), parity protection, out-of-band register access via SMBus, memory mirror- ing, memory sparing, and Hot-plug support on the PCI-Express Interface.
Main Features of the 5500 Series Processor and the 5520 Chipset
• Four processor cores in each processor with 8MB shared cache among cores
• Two full-width Intel QuickPath interconnect links, up to 6.4 GT/s of data transfer rate in each direction
• Virtualization Technology, Integrated Management Engine supported
• Point-to-point cache coherent interconnect, Fast/narrow unidirectional links, and Concurrent bi-directional traffic
