Chapter 1: Introduction1-2Processor and Chipset OverviewBuilt upon the functionality and the capability of the 5500/5600 Series Processorplatform, the X8DTN /X8DTN -LR motherboard provides the performance andfeature set required for dual-processor-based high-end systems with configurationoptimized for intensive application and high-end server platforms. The 5500/5600Series Processor platform consists of the 5500/5600 Series (LGA 1366) processor, the 5520 (North Bridge), and the ICH10R (South Bridge). With the IntelQuickPath Interconnect (QPI) controller built in, the 5500/5600 Series Processorplatform is the first dual-processing platform to offer the next generation pointto-point system interconnect interface that replaces the current Front Side BusTechnology and substantially enhances system performance by utilizing serial linkinterconnections, allowing for increased bandwidth and scalability.The 5520 connects to each processor through an independent QuickPath Interconnect link. Each link consists of 20 pairs of uni-directional differential lanes fortransmission and receiving in addition to a differential forwarded clock. A full-widthQPI link pair provides 84 signals. Each processor supports two QuickPath link,one going to the other processor and the other to the 5520.The 5520 supports up to 36 PCI Express Gen2 lanes, peer-to-peer read and writetransactions. The ICH10R supports up to 6 PCI-Express ports, six SATA portsand 10 USB connections.In addition, the 5500/5600 Series Processor platform also offers a wide range ofRAS (Reliability, Availability and Serviceability) features. These features includememory interface ECC, x4/x8 Single Device Data Correction (SDDC), Cyclic Redundancy Check (CRC), parity protection, out-of-band register access via SMBus,memory mirroring, and Hot-plug support on the PCI-Express Interface. The Main Features of the 5500/5600 Series Processor andthe 5520 ChipsetFour processor cores in each processor with 8MB shared cache among coresTwo full-width Intel QuickPath interconnect links, up to 6.4 GT/s of data transferrate in each directionVirtualization Technology, Integrated Management Engine supportedPoint-to-point cache coherent interconnect, Fast/narrow unidirectional links, andConcurrent bi-directional trafficError detection via CRC and Error correction via Link level retry1-11

X8DTN /X8DTN -LR User's Manual1-3Special FeaturesRecovery from AC Power LossBIOS provides a setting for you to determine how the system will respond whenAC power is lost and then restored to the system. You can choose for the systemto remain powered off (in which case you must hit the power switch to turn it backon) or for it to automatically return to a power- on state. See the Advanced BIOSSetup section to change this setting. The default setting is Last State.1-4PC Health MonitoringThis section describes the PC health monitoring features of the X8DTN /X8DTN LR. All have an onboard System Hardware Monitor chip that supports PC healthmonitoring. An onboard voltage monitor will scan these onboard voltages continuously: CPU1 Vcore, CPU2 Vcore, 5Vin, 12V, -12V 3.3Vcc (V), and Battery Voltage. Once a voltage becomes unstable, a warning is given or an error message issent to the screen. Users can adjust the voltage thresholds to define the sensitivityof the voltage monitor.Fan Status Monitor with Firmware ControlThe PC health monitor can check the RPM status of the cooling fans. The onboardCPU and chassis fans are controlled by Thermal Management via BIOS (underHardware Monitoring in the Advanced Setting).Environmental Temperature ControlThe thermal control sensor monitors the CPU temperature in real time and will turnon the thermal control fan whenever the CPU temperature exceeds a user-definedthreshold. The overheat circuitry runs independently from the CPU. Once it detectsthat the CPU temperature is too high, it will automatically turn on the thermal fancontrol to prevent any overheat damage to the CPU. The onboard chassis thermalcircuitry can monitor the overall system temperature and alert users when the chassis temperature is too high.Warning! To avoid possible system overheating, be sure to provide adequate airflow to the system.System Resource AlertThis feature is available when used with Supero Doctor III in the Windows OSenvironment or used with Supero Doctor II in Linux. Supero Doctor is used to1-12

Chapter 1: Introductionnotify the user of certain system events. For example, you can also configureSupero Doctor to provide you with warnings when the system temperature, CPUtemperatures, voltages and fan speeds go beyond a pre-defined range.1-5ACPI FeaturesACPI stands for Advanced Configuration and Power Interface. The ACPI specification defines a flexible and abstract hardware interface that provides a standardway to integrate power management features throughout a PC system, includingits hardware, operating system and application software. This enables the systemto automatically turn on and off peripherals such as CD-ROMs, network cards, harddisk drives and printers.In addition to enabling operating system-directed power management, ACPIprovides a generic system event mechanism for Plug and Play and an operatingsystem-independent interface for configuration control. ACPI leverages the Plugand Play BIOS data structures while providing a processor architecture-independentimplementation that is compatible with Windows XP/Windows 2003/Windows 2008/Windows Vista Operating Systems.Slow Blinking LED for Suspend-State IndicatorWhen the CPU goes into a suspend state, the chassis power LED will start blinkingto indicate that the CPU is in suspend mode. When the user presses any key, theCPU will wake-up and the LED will automatically stop blinking and remain on.Main Switch Override MechanismWhen an ATX power supply is used, the power button can function as a systemsuspend button to make the system enter a SoftOff state. The monitor will besuspended and the hard drive will spin down. Pressing the power button againwill cause the whole system to wake-up. During the SoftOff state, the ATX powersupply provides power to keep the required circuitry in the system "alive." In casethe system malfunctions and you want to turn off the power, just press and holdthe power button for 4 seconds. This option can be set in the Power section ofthe BIOS Setup routine.1-6Power SupplyAs with all computer products, a stable power source is necessary for proper andreliable operation. It is even more important for processors that have high CPUclock rates.1-13

X8DTN /X8DTN -LR User's ManualThe X8DTN /X8DTN -LR can accommodate 24-pin ATX power supplies. Althoughmost power supplies generally meet the specifications required by the CPU, someare inadequate. In addition, the 12V 8-pin power connections are also required toensure adequate power supply to the system. Also your power supply must supply1.5A for the Ethernet ports.Warning: To prevent damage to your power supply or mother
