1-2 Chipset and Processor Features Overview

Built upon the functionality and the capability of the Intel 5100 chipset, the

X7DCX motherboard provides the performance and feature set required for dual

processor-based high-end computer systems with conﬁ guration options optimized

for intensive computing, high energy-efﬁ ciency and complex business applications.

The 5100 chipset supports single or dual Intel Xeon 64-bit Quad-Core/Dual-Core

5400/5300/5200/5100 Sequence processors with front side bus speeds of up to

1333 MHz. 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,

1333/1066 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 four DDR2 667 MHz/533 MHz DIMM modules, providing a total memory capacity

of up to 48 GB.

The 5100 MCH also provides three x8 PCI-Express interfaces and one x4 DMI

Interface to the ICH9R. Each PCI Express port on the MCH provides 4 GB/s bi-

directional bandwidth if conﬁ gured as a x8 port, or 2 GB/s bi-directional bandwidth

if conﬁ gured as a x4 port.

The Ninth Generation I/O Controller Hub (ICH9R)

The I/O Controller ICH9R provides the data buffering and interface arbitration re-

quired for the system to operate efﬁ ciently. 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 one PCI-Express x16 slot, six Serial ATA ports and six 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 genera-

tion of client management through the use of PROActive technology in conjunction

with Intel's next generation Gigabit Ethernet controllers.

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 X7DCX. All have an

onboard System Hardware Monitor chip that supports PC health monitoring.

Voltage Monitoring

An onboard voltage monitor will scan the CPU Core, Chipset, +1.8V, +3.3V, +5V,

+12V, -12V, +3.3V Standby, +5V Standby and VBAT voltages 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 deﬁ ne 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-deﬁ ned

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 chas-

sis temperature is too high.

CPU Overheat LED and Control

This feature is available when the user enables the CPU overheat warning function

in the BIOS. This allows the user to deﬁ ne an overheat temperature. When the CPU

temperature reaches the pre-deﬁ ned overheat threshold, both the overheat fan and

the warning LED are triggered.

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 insufﬁ cient hard drive space for saving the

data, you can be alerted of the potential problem. You can also conﬁ gure Supero

Doctor to provide you with warnings when the system temperature goes beyond

a pre-deﬁ ned range.

1-5 ACPI Features

ACPI stands for Advanced Conﬁ guration and Power Interface. The ACPI speciﬁ -

cation deﬁ nes a ﬂ exible 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 conﬁ guration control. ACPI leverages the Plug

and Play BIOS data structures while providing a processor architecture-indepen-

dent 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. The external modem ring-on can

only be used with an ATX 2.01 (or above) compliant power supply.

Wake-On-LAN is deﬁ ned 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 trafﬁ c is kept

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 X7DCX can only accommodate 24-pin ATX power supply. Although most power

supplies generally meet the speciﬁ cations required by the motherboard, some are

inadequate. You should use one that will supply at least 400W of power, depend-

ing on your system conﬁ guration. 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 Speciﬁ cation 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 ﬁ lter to shield the computer from noise.
