1-2 Chipset Overview

The Intel 3210 Chipset, designed for use with the Xeon 3000 Series Processor,

is comprised of two primary components: the Memory Controller Hub (MCH)

and the I/O Controller Hub (ICH9R). In addition, Intel's PCI-X (PXH) is used for

added functionality. The X7SB4/X7SBE provides the performance and feature-set

required for the cutting-edge, cost-effective server market.

Memory Controller Hub (MCH)

ThefunctionoftheMCHistomanagethedataowbetweenfourinterfaces:the

CPU interface, the DDR2 System Memory Interface, the PCI Express Interface

(Note Below), and the Direct Media Interface (DMI). The MCH is optimized for the

Xeon Core™2 processor in the 45nm/65nm process in the LGA775 Land Grid

Array Package. It supports one or two channels of DDR2 SDRAM.

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

quiredforthesystemtooperateef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

two PCI-Express devices, six Serial ATA ports, and up to seven USB 2.0 ports/

headers. 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 controller.

Intel ICH9R System Features

The I/O Controller Hub provides the I/O subsystem with access to the rest of the

system. Functions and capabilities include:

X7SB4/X7SBE 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 section to change this setting. (Note: Default: Last State.)

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the X7SB4/X7SBE.

All have an onboard System Hardware Monitor chip that supports PC health

monitoring.

Onboard Voltage Monitors for the CPU Cores, Memory Voltage,

+1.8V, +3.3V, +5V, +5V Standby, +12V, −12V and Vbatt.(via SuperO

Doctor)

An onboard voltage monitor will scan these 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denethesensitivityofthe

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 the 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passesauser-dened

overheating 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 the CPU from overheating. The onboard chassis

thermal circuitry can monitor the overall system temperature and alert users when

the chassis 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 dene an overheat temperature. When the

CPU temperature passes this temperature 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 insufcient hard drive space for saving the

data,youcanbealertedofthepotentialproblem.YoucanalsocongureSupero

cationdenesa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con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 Server Operating Systems.

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

to "wake-up" the whole system. 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 SoftOff state. Note that external modem ring-on can

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

Wake-On-LAN (WOL)

trackingcanoccurafterhoursandonweekendssothatdailyLANtraf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 X7SB4/X7SBE can only accommodate 24-pin ATX power supplies. Although

mostpowersuppliesgenerallymeetthespecicationsrequiredbytheCPU,some

are inadequate. In addition, the 12V 8-pin power connection is also required to

ensure adequate power supply to the system. Also your power supply must sup-

ply 1.5A for the Ethernet ports. It is strongly recommended that you use a high

qualitypowersupply that meets ATX power supply Specication 2.01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

power surge protector to help avoid problems caused by power surges.
