Preface
About This Manual

This manual is written for system integrators, PC technicians and
knowledgeable PC users. It provides information for the installation and use
of the X6DHR-8G2/X6DHR-iG2 motherboard. The X6DHR­8G2/X6DHR-iG2 supports single or dual Intel® NoconaTM processors at a
800 MHz front side bus. Based upon Intel's NetBurst microarchitecture with
EM64T support, the Nocona processor supports the IA-32 software and
includes features found in the XeonTM processor such as a Rapid Execu­tion Engine, an Execution Trace Cache, and Hyper Pipelined Technology,
which includes a multi-stage pipeline, allowing the processor to reach
much higher core frequencies. The 800 MHz system bus is a quad-pumped
bus running off a 200 MHz system clock making 6.4 GB per second data
transfer rates possible. Packaged in a 604-pin Flip Chip Micro Pin Grid
Array(FC-mPGA4) platform in a Zero Insertion Force(ZIF) socket (mPGA

604), the Nocona Processor (800 MHz) supports Hyper-Threading Technol­ogy and is ideal for high performance workstation and server environments
with up to two processors on one system bus. Please refer to the mother­board specifications pages on our web site (http://www.supermicro.com/
Product_page/product-m.htm) for updates on supported processors. This
product is intended to be professionally installed.

Introduction

1-2 Chipset Overview

Built upon the functionality and the capability of the Intel E7520
(Lindenhurst) chipset, The X6DHR-8G2/X6DHR-iG2 motherboard provides
the performance and feature set required for dual processor-based serv­ers, with configuration options optimized for communications, presentation,
storage, computation or database applications. The Intel E7520 (Lindenhurst)
chipset consists of the following components: the E7520 (Lindenhurst)
Memory Controller Hub (MCH), the ICH5R Controller Hub (ICH), the Intel PCI­X Hub (PXH).

The E7520 MCH supports single or dual Nocona processors with Front Side
Bus speeds of 800 MHz. Its memory controller provides direct connection to
two channels of registered DDRII with a marched system bus address and
data bandwidths of up to 6.4GB/s. The E7520 also supports the new PCI­Express high speed serial I/O interface for superior I/O bandwidth. The MCH
provides three configurable x8 PCI Express interfaces which may alterna­tively be configured 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 Specification, Rev. 1.0a, such
as 82546GB GLAN Adaptor, H/W RAID controllers and TCP/IP Off-load en­gines. The MCH interfaces with the ICH5R I/O Controller Hub (ICH5) via a
dedicated Hub Interface supporting 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 con­figured for standard PCI -X 1.0 protocol.

ICH5R System Features

In addition to providing the I/O subsystem with access to the rest of the
system, the ICH5R I/O Controller Hub integrates many I/O functions.

The ICH5R I/O Controller Hub integrates: 2-channel Ultra ATA/100 Bus Mas­ter IDE Controller, two Serial ATA (SATA) Host w/RAID0, RAID1 support,
SMBus 2.0 Controller, LPC/Flash BIOS Interface, PCI 2.2 Interface and Sys­tem Management Controller.

Introduction

X6DHR-8G2/X6DHR-iG2 User's Manual

1-3 Special Features

BIOS Recovery

The BIOS Recovery function allows you to recover your BIOS image file if
the BIOS flashing procedure fails (see Section 3-3).

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 power­on state. See the Power Lost Control setting in the Advanced BIOS Setup
section (Peripheral Device Configuration) to change this setting. The de­fault setting is Always On.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER
X6DHR-8G2/X6DHR-iG2. All have an onboard System Hardware Monitor
chip that supports PC health monitoring.

Onboard Voltage Monitors for the CPU Cores, Chipset
Voltage, Memory Voltage, +3.3V, +5V, +12V, -12V, and +5V
Standby

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 define the
sensitivity of the voltage monitor.

Fan Status Monitor with Firmware/Software On/Off 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.

Chapter 1: Introduction

1-11

Introduction

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. It can continue to monitor for overheat conditions even when the
CPU is in sleep mode. Once it detects that the CPU temperature is too high,
it will automatically turn on the thermal control fan 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.

CPU Fan Auto-Off in Sleep Mode

The CPU fan activates when the power is turned on. It continues to operate
when the system enters Standby mode. When in sleep mode, the CPU will
not run at full power, thereby generating less heat.

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 define an overheat tempera­ture. When this temperature is exceeded, both the overheat fan and the
warning LED are triggered.

System Resource Alert (*via Supero Doctor III)

This feature is available when used with Intel's LANDesk Client Manager
(optional). For example, if the system is running low on virtual memory and
there is insufficient hard drive space for saving the data, you can be
alerted of the potential problem.

Auto-Switching Voltage Regulator for the CPU Core

The auto-switching voltage regulator for the CPU core can support up to
20A current and auto-sense voltage IDs ranging from 0.83V to 1.63V. This
will allow the regulator to run cooler and thus make the system more stable.

1-12

Introduction

X6DHR-8G2/X6DHR-iG2 User's Manual

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
Operating Systems.

Microsoft OnNow

The OnNow design initiative is a comprehensive, system-wide approach to
system and device power control. OnNow is a term for a PC that is always
on but appears to be off and responds immediately to user or other re­quests.

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. Depressing
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

Chapter 1: Introduction

1-13

Introduction

you want to turn off the power, just depress 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)

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, up­dates and asset tracking can occur after hours and on weekends so that
daily LAN traffic 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.

1-6 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 SUPER X6DHR-8G2/X6DHR-iG2 accommodates ATX power 20-pin sup­plies. Although most power supplies generally meet the specifications re­quired by the system, some are inadequate. You should use one that will
supply at least 400W of power.

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.

Introduction

X6DHR-8G2/X6DHR-iG2 User's Manual

NOTES: 1. A 12V 8-pin power (JID1) is required to support Intel
Nocona CPUs. In addition, a 12V 4-pin PWR connection is also re­quired for the system to function properly. See Section 2-5 for
details on connecting the power supply cables.

2. Be sure to use the correct type of onboard CMOS battery as
specified by the Manufacturer. Do not install the CMOS battery up­side down to avoid possible explosion.

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), one of which supports serial infrared communication. Each UART
includes a 16-byte send/receive FIFO, a programmable baud rate generator,
complete modem control capability and a processor interrupt system. 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).

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.

The IRQs, DMAs and I/O space resources of the Super I/O can flexibly
adjust to meet ISA PnP requirements, which support ACPI and APM (Ad­vanced Power Management).

2-1 Static-Sensitive Devices

Electric-Static-Discharge (ESD) can damage electronic components. To pre­vent damage to your system board, it is important to handle it very carefully.
The following measures are generally sufficient 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.

Warning: Please use the correct type of onboard CMOS battery as
specified by the Manufacturer. Do not install the CMOS battery up­side down 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.

2-2

X6DHR-8G2/X6DHR-iG2 User's Manual

IMPORTANT: Always connect the power cord last and always remove it
before adding, removing or changing any hardware components. Make
sure that you install the processor into the CPU socket before you install
the CPU heat sink.

2-2 Nocona 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 first.)

1. Place the CPU retention bracket
on top of the CPU mounting plate.

Heatsink Installation

1. Do not apply any thermal compound

to the heatsink or the CPU die-the
required amount has already been
applied.

2. Place the heatsink on top of the

CPU so that the four mounting holes
are aligned with those on the retention
mechanism.

3. Screw in two diagonal screws (ie

the #1 and the #2 screws) until just
snug (-do not fully tighten the screws
to avoid possible damage to the CPU.)

4. Finish the installation by fully

tightening all four screws.

2. Insert the CPU in the socket,

making 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.

2. Hold the heatsink as show in the
picture on the right and gently wriggle
the heatsink to loosen it from the CPU.
(Do not use excessive force when
wriggling the heatsink!!)

3. Once the CPU is loosened from the
heatsink, remove the heatsink from the
CPU socket.

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 the location of all the mounting holes for both the
motherboard and the chassis match. Although a chassis may have both
plastic and metal mounting fasteners, metal ones are highly recommended
because they ground the motherboard to the chassis. Make sure 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 to the chassis.)

Figure 2-2. Installing and Removing DIMMs

To Install:

Insert module
vertically and
press down
until it snaps
into place.
Pay attention
to the
alignment
notch at the
bottom.

2-3 Installing DIMMs

Note: Check the Supermicro web site for recommended memory modules:

http://www.supermicro.com/TECHSUPPORT/FAQs/Memory_vendors.htm

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 (see step 1).

DIMM Installation (See Figure 2-2)

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, then DIMM 1B, and so on.

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).

Memory Support

The X6DHR-8G2/X6DHR-iG2 supports up to 16 GB of Registered DDRII-400
(PC3200) memory (recommended by the Manufacturer). All motherboards
were designed to support 2 GB modules in each slot, but has only been
verified for up to 1.0 GB modules.

Chapter 2: Installation

2-7

To Remove:

Use your thumbs to gently push near the edge of both ends of
the module. This should release it from the slot.
