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

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.
The
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.

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.
