Block Diagram of the Intel 5100 Chipset
Note: This is a general block diagram. Please see the previous Motherboard Features pages for details on the features of each motherboard.
1-8
Chapter 1: Introduction
1-2 Chipset and Processor Features Overview
Built upon the functionality and the capability of the Intel 5100 chipset, the X7DCL-
3/X7DCL-i motherboard provides the performance and feature set required for dual processor-based high-end servers with configuration options optimized for intensive computing, high energy-efficiency and complex business applications.
The 5100 chipset supports single or dual Intel Xeon 64-bit Quad Core/Dual Core 5400/5300/5200/5100 Series processors with front side bus speeds of up to 1.333 GHz. The chipset consists of the 5100 Memory Controller Hub (MCH), Intel I/O Controller Hub (ICH9R) and the I/O subsystem.
The 5100 Memory Controller Hub (MCH)
The Intel 5100 MCH chip is designed for symmetric multiprocessing across two independent front side bus interfaces. Each front side bus uses a 64-bit wide, 1066/1333 MTS data bus capable of transferring data at 8.5/10.6 GB/s for a total bandwidth of 17/21.3 GB/s. The MCH supports a 36-bit wide address bus and up to six DDR2 667 MHz/533 MHz DIMM modules, providing a total memory capacity of up to 32 GB.
The 5100 MCH also provides six x4 PCI-Express interfaces and one x4 DMI Interface to the ICH9R. Each PCI Express port on the MCH provides 4 GB/s bidirectional bandwidth if configured as a x8 port, or 2 GB/s bi-directional bandwidth if configured as a x4 port.
The Ninth Generation I/O Controller Hub (ICH9)
The I/O Controller ICH9R provides the data buffering and interface arbitration required for the system to operate efficiently. It also provides the bandwidth needed for the system to maintain its peak performance. The Direct Media Interface (DMI) provides the connection between the MCH and the ICH9R. The ICH9R supports up to six PCI-Express x1 slots, six Serial ATA ports and twelve USB 2.0 ports. In addition, the ICH9R offers the Intel Matrix Storage Technology which provides various RAID options for data protection and rapid data access. It also supports the next generation of client management through the use of PROActive technology in conjunction with Intel's next generation Gigabit Ethernet controllers.

X7DCL-3/X7DCL-i User's Manual
1-3 Special Features
Recovery from AC Power Loss
BIOS provides a setting for you to determine how the system will respond when AC power is lost and then restored to the system. You can choose for the system to remain powered off (in which case you must hit the power switch to turn it back on) or for it to automatically return to a power-on state. See the Power Lost Control setting in the Advanced BIOS Setup section to change this setting. The default setting is Last State.
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the X7DCL-3/X7DCL- i. All have an onboard System Hardware Monitor chip that supports PC health monitoring.
Onboard Voltage Monitors
An onboard voltage monitor will scan for the CPU Cores, Chipset Voltage, +1.8V, +3.3V, +5V, +12V, -12V, +3.3V Standby, +5V Standby and VBAT continuously. Once a voltage becomes unstable, a warning is given or an error message is sent to the screen. Users can adjust the voltage thresholds to define the sensitivity of the voltage monitor.
Fan Status Monitor with Firmware Control
The PC health monitor can check the RPM status of the cooling fans. The onboard CPU and chassis fans are controlled by Thermal Management via BIOS (under Hardware Monitoring in the Advanced Setting).
Environmental Temperature Control
The thermal control sensor monitors the CPU temperature in real time and will turn on the thermal control fan whenever the CPU temperature exceeds a user-defined threshold. The overheat circuitry runs independently from the CPU. Once it detects that the CPU temperature is too high, it will automatically turn on the thermal fan control to prevent any overheat damage to the CPU. The onboard chassis thermal circuitry can monitor the overall system temperature and alert users when the chassis temperature is too high.
System Resource Alert
This feature is available when used with Supero Doctor III in the Windows OS environment or used with Supero Doctor II in Linux. Supero Doctor is used to notify the user of certain system events. For example, if the system is running low on virtual memory and there is insufficient hard drive space for saving the data,
1-10
Chapter 1: Introduction
you can be alerted of the potential problem. You can also configure Supero Doctor to provide you with warnings when the system temperature goes beyond a predefined range.
1-5 ACPI Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI specification defines a flexible and abstract hardware interface that provides a standard way to integrate power management features throughout a PC system, including its hardware, operating system and application software. This enables the system to automatically turn on and off peripherals such as CD-ROMs, network cards, hard disk drives and printers. This also includes consumer devices connected to the PC such as VCRs, TVs, telephones and stereos.
In addition to enabling operating system-directed power management, ACPI provides a generic system event mechanism for Plug and Play and an operating system-independent interface for configuration control. ACPI leverages the Plug and Play BIOS data structures while providing a processor architecture-independent implementation that is compatible with Windows 2000, Windows XP and Windows 2003 Servers.
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start blinking to indicate that the CPU is in suspend mode. When the user presses any key, the CPU will wake-up and the LED will automatically stop blinking and remain on.
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a system suspend button to make the system enter a SoftOff state. The monitor will be suspended and the hard drive will spin down. Pressing the power button again will cause the whole system to wake-up. During the SoftOff state, the ATX power supply provides power to keep the required circuitry in the system "alive". In case the system malfunctions and you want to turn off the power, just press and hold the power button for 4 seconds. This option can be set in the Power section of the BIOS Setup routine.
External Modem Ring-On
Wake-up events can be triggered by a device such as the external modem ringing when the system is in the Standby or Off state. Note that external modem ring-on can only be used with an ATX 2.01 (or above) compliant power supply.
Wake-On-LAN is defined as the ability of a management application to remotely power up a computer that is powered off. Remote PC setup, up-dates and asset tracking can occur after hours and on weekends so that daily LAN traffic is kept
1-11
X7DCL-3/X7DCL-i User's Manual
to a minimum and users are not interrupted. The motherboard has a 3-pin header (WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has WOL capability. In addition, an onboard LAN controller can also support WOL without any connection to the WOL header. The 3-pin WOL header is to be used with a LAN add-on card only.
Note: Wake-On-LAN requires an ATX 2.01 (or above) compliant power supply.
1-6 Power Supply
As with all computer products, a stable power source is necessary for proper and reliable operation. It is even more important for processors that have high CPU clock rates.
The X7DCL-3/X7DCL-i can only accommodate 24-pin ATX power supply. Although most power supplies generally meet the specifications required by the motherboard, some are inadequate. You should use one that will supply at least 400W of power. In addition, the 12V 8-pin is also required for adequate power supply to the CPU. Also your power supply must supply 1.5A for the Ethernet ports.
It is strongly recommended that you use a high quality power supply that meets
ATX power supply Specification 2.02 or above. It must also be SSI compliant (info at http://www.ssiforum.org/). Additionally, in areas where noisy power transmission is present, you may choose to install a line filter to shield the computer from noise. It is recommended that you also install a power surge protector to help avoid problems caused by power surges.
1-7 Super I/O
The disk drive adapter functions of the Super I/O chip include a floppy disk drive controller that is compatible with industry standard 82077/765, a data separator, write pre-compensation circuitry, decode logic, data rate selection, a clock generator, drive interface control logic and interrupt and DMA logic. The wide range of functions integrated onto the Super I/O greatly reduces the number of components required for interfacing with floppy disk drives. The Super I/O supports 360 K, 720 K, 1.2
M, 1.44 M or 2.88 M disk drives and data transfer rates of 250 Kb/s, 500 Kb/s or 1 Mb/s. It also provides two high-speed, 16550 compatible serial communication ports (UARTs). Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps as well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which support higher speed modems.
The Super I/O supports one PC-compatible printer port (SPP), Bi-directional Printer
Port (BPP), Enhanced Parallel Port (EPP) or Extended Capabilities Port (ECP).
1-12
Chapter 1: Introduction
The Super I/O provides functions that comply with ACPI (Advanced Configuration and Power Interface), which includes support of legacy and ACPI power management through an SMI or SCI function pin. It also features auto power management to reduce power consumption.

3. Once the heatsink is loosened, remove the it from the CPU socket.
2-4
Chapter 2: Installation
4. Clean the surface of the CPU and the heatsink to get rid of the old thermal grease. Reapply the proper amount of thermal grease on the surface before you re-install the CPU and the heatsink.
Mounting the Motherboard in the Chassis
All motherboards have standard mounting holes to fit different types of chassis.
Make sure that the locations of all the mounting holes for both motherboard and chassis match. Make sure that the metal standoffs click in or are screwed in tightly. Then, use a screwdriver to secure the motherboard onto the motherboard tray. (Note: some components are very close to the mounting holes. Please take precautionary measures to prevent damage done to these components when you install the motherboard into the chassis.)
Caution: To avoid damaging the motherboard and its components, please do not use a force greater than 8 lb/inch on each mounting screw during motherboard installation.
2-3 Installing DIMMs
Note: Check the SuperMicro web site for recommended memory modules.
CAUTION
Exercise extreme care when installing or removing DIMM modules to prevent any possible damage. Also note that the memory is interleaved to improve performance.
DIMM Installation
1.Insert the desired number of DIMMs into the memory slots, starting with DIMM #1A. The memory scheme is interleaved, so you must install two modules at a time, beginning with DIMM 1A, DIMM 2A, then DIMM 1B, DIMM 2B, and DIMM 1C, DIMM 2C. (See the Memory Installation Table Below.)
2.Insert each DIMM module vertically into its slot. Pay attention to the notch along the bottom of the module to prevent inserting the DIMM module incorrectly.
3.Gently press down on the DIMM module until it snaps into place in the slot. Repeat for all modules (See step 1 above.)

X7DCL-3/X7DCL-i User's Manual
Memory Support
The X7DCL-3/X7DCL-i supports up to 48 GB Single-Rank/Dual Rank, Registered ECC DDR2 667/533 in 6 DIMMs (The amount and type of memory supported is dependent on the PCB revision. See Note 1 Below). Populating DIMM slots with pairs of memory modules of the same size and same type will result in Interleaved Memory which will improve memory performance.
Note 1: For the PCB Rev. 1.1 motherboard, Slots 1A and 2A support Dual-Rank modules; however, Slots 1B, 2B, 1C and 2C support Single-Rank memory only
(Maximum of 32 GB). The PCB Rev. 1.1a board supports 6 Dual-Rank or 6 SingleRank modules (Maximum of 48 GB).

For memory to work properly, you need to follow the restrictions listed above. )
Note 2: Due to OS limitations, some operating systems may not show more than 4 GB of memory.
Note 3: Due to memory allocation to system devices, memory remaining available for operational use will be reduced when 4 GB of RAM is used. The reduction in memory availability is disproportional. (Refer to the following Memory Availability Table for details. For Microsoft Windows users: Microsoft implemented a design change in Windows XP with Service Pack 2 (SP2) and Windows Vista. This change is specific to the Physical Address Extension (PAE) mode behavior which improves driver compatibility.
