1-2 Chipset Overview

Built upon the functionality and the capability of the E7520 Lindenhurst chipset,

The X6DHR-C8 motherboard provides the performance and feature set required

for dual processor-based servers, with conﬁ guration options optimized for commu-

nications, server security, storage, computation or database applications. The Intel

E7520 Lindenhurst chipset consists of the following components: the Lindenhurst

Memory Controller Hub (MCH), the 82801ER I/O Controller Hub 5-R (ICH5-R), and

the PCI-X Hub.

The E7520 Lindenhurst MCH supports single or dual Nocona processors with Front

Side Bus speeds of up to 800 MHz(*Note). Its memory controller provides direct

connection to two channels of registered DDR2 400 with a marched system bus

address and data bandwidths of up to 6.4GB/s. The Lindenhurst also supports the

new PCI Express high speed serial I/O interface for superior I/O bandwidth. The

MCH provides three conﬁ gurable x8 PCI Express interfaces which may alternatively

be conﬁ gured as two independent x4 PCI Express interfaces. These interfaces

support connection of the MCH to a variety of other bridges that are compliant

with the PCI Express Interface Speciﬁ cation, Rev. 1.0a. The MCH interfaces with

the 82801ER I/O Controller Hub 5-R (ICH5R) via a dedicated Hub Interface sup-

porting a peak bandwidth of 266 MB/s using a x4 base clock of 66 MHz. The PXH

provides connection between a PCI Express interface and two independent PCI

bus interfaces that can be conﬁ gured for standard PCI 2.3 protocol, as well as the

enhanced high-frequency PCI-X protocol. The PXH can be conﬁ gured to support for

64-bit PCI devices running at 33 MHz, 66 MHz, 100 MHz, and 133 MHz.

The ICH5R I/O Controller Hub provides legacy support similar to that of previous

ICH-family devices, but with extensions in RAID 0,1 support, Serial ATA Technology,

and an integrated ASF Controller. In addition, the ICH5R also provides various inte-

grated functions, including a two-channel Ultra ATA/100 bus master IDE controller,

USB 2.0 host controllers, an integrated 10/100 LAN controller, an LPC ﬁ rmware hub

(FWH) and Super IO interface, a System Management Interface, a power manage-

ment interface, integrated IOxAPIC and 8259 interrupt controllers.

(*Notes: The CPU FSB speed is set at 800 MHz by the Manufacturer. Please do

not change the CPU FSB setting.)

X6DHR-C8 User's Manual

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the X6DHR-C8. The

motherboard has an onboard System Hardware Monitor chip that supports PC

health monitoring.

Onboard Voltage Monitors for the CPU Core, +3.3V, +5V, +3V

standby, +12V and −12V

The onboard voltage monitor will scan these voltages continuously. Once a volt-

age becomes unstable, it will give a warning or send an error message to the

screen. Users can adjust the voltage thresholds to deﬁ ne the sensitivity of the

voltage monitor.

Fan Status Monitor with Firmware Speed Control

The PC health monitor can check the RPM status of the cooling fans. The onboard

fans are controlled by Thermal Management via BIOS.

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 this

temperature reaches the threshold, the CPU thermal trip feature will be activated

and it will send a signal to the Speaker LED and, at the same time, the CPU speed

will be decreased.

1-4 Power Conﬁ guration Settings

This section describes features of your motherboard that deal with power and

power settings.

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.

BIOS Support for USB Keyboard

If the USB keyboard is the only keyboard in the system, it keyboard will function

like a normal keyboard during system boot-up.

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function as a system

suspend button. When the user depresses the power button, the system will enter

a SoftOff state. The monitor will be suspended and the hard drive will spin down.

Chapter 1: Introduction

1-11

Depressing the power button again will cause the whole system to wake-up. Dur-

ing 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 depress and hold the power button for 4 seconds. The power

will turn off and no power will be provided to the motherboard.

Wake Ring-On (WOR)

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)

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. Wake-On-LAN must be enabled in BIOS. Note that Wake-On-LAN

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

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 pro-

vides 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-independent

implementation that is compatible with both Windows and Linux Operating Sys-

tems.

X6DHR-C8 User's Manual

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 of 1 GHz and faster.

X6DHR-C8 accommodates 12V ATX power supplies. Although

most power supplies generally meet the speciﬁ cations required by the CPU, some

are inadequate. The X6DHR-C8 accommodates ATX power supplies. It is strongly

recommended that you use a high quality power supply that meets ATX power

supply Speciﬁ cation 2.02 or above. Also your power supply must supply 1.5A for

the Ethernet ports. 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. It is recommended that

you also install a power surge protector to help avoid problems caused by power

surges. Please note that the 8-pin 12V (JWP3) and the 4-pin 12V (JPW2) power

connectors are also required to provide adequate power to you system.

2-1 Static-Sensitive Devices

Electric-Static-Discharge (ESD) can damage electronic com ponents. To prevent

damage to your system board, it is important to handle it very carefully. The following

measures are generally sufﬁ cient to protect your equipment from ESD.

Precautions

• Use a grounded wrist strap designed to prevent static discharge.

• Touch a grounded metal object before removing the board from the antistatic

bag.

• Handle the board by its edges only; do not touch its components, peripheral

chips, memory modules or gold contacts.

• When handling chips or modules, avoid touching their pins.

• Put the motherboard and peripherals back into their antistatic bags when not in

use.

• For grounding purposes, make sure your computer chassis provides excellent

conductivity between the power supply, the case, the mounting fasteners and

the motherboard.

• Use only the correct type of onboard CMOS battery. Do not install the onboard

upside down battery to avoid possible explosion.

Unpacking

The motherboard is shipped in antistatic packaging to avoid static damage. When

unpacking the board, make sure the person handling it is static protected.

X6DHR-C8 User's Manual

IMPORTANT: Always connect the power cord last and always remove it before add-

ing, removing or changing any hardware components. Make sure that you install

the processor into the CPU socket before you install the CPU (CEK) heat sink.

2-2 Processor and Heatsink Installation

When handling the processor package, avoid placing direct pressure

on the label area of the fan. Also, do not place the motherboard on a

conductive surface, which can damage the BIOS battery and prevent

the system from booting up.

CPU Installation

1. Lift the lever on the CPU socket: lift

the lever completely as shown on the

picture on the right; otherwise, you

will damage the CPU socket when

power is applied. (Install CPU1 ﬁ rst.)

2. Insert the CPU in the socket, mak-

ing sure that pin 1 of the CPU aligns

with pin 1 of the socket (both corners

are marked with a triangle). When

using only one CPU, install it into CPU

socket #1 (socket #2 is automatically

disabled if only one CPU is used).

3. Press the lever down until you

hear the *click* so you can be

sure that the CPU is securely

installed in the CPU socket.
