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 X6DH8-G2/X6DHE-G2 motherboard. The X6DH8-G2/
X6DHE-G2 supports single or dual Intel® NoconaTM processors at a 800
MHz front side bus. Based upon Intel's NetBurst microarchitecture, the
Nocona processor supports the IA-32 software and includes features
found in the XeonTM processor such as Hyper Pipelined Technology, which
includes a multi-stage pipeline, allowing the processor to operate at much
higher core frequencies. 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, which supports Hyper-Threading Technology
and Intel EM64T, 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.

Manual Organization

Chapter 1 begins with a checklist of what should be included in your

mainboard box, describes the features, specifications and performance of

Introduction

1-2 Chipset Overview

Built upon the functionality and the capability of the E7520 Lindenhurst
chipset, The X6DH8-G2/X6DHE-G2 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 Lindenhurst Memory Controller Hub (MCH),
the 82801ER I/O Controller Hub 5-R (ICH5-R), and the Intel 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 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. The MCH interfaces with the
82801ER I/O Controller Hub 5-R (ICH5R) via a dedicated Hub Interface sup­porting a peak bandwidth of 266 MB/s using a x4 base clock of 66 MHz. The
PXH provide connection between a PCI Express interface and two indepen­dent PCI bus interfaces that can be configured for standard PCI 2.3 proto­col, as well as the enhanced high-frequency PCI-X protocol. The PXH can
be configured to support for 32- or 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 integrated 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 firmware hub (FWH) and Super IO interface,
a System Management Interface, a power management interface, integrated
IOxAPIC and 8259 interrupt controllers.

X6DH8-G2/X6DHE-G2 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 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 X6DH8-G2/
X6DHE-G2. All have an onboard System Hardware Monitor chip that sup­ports PC health monitoring.

Onboard Voltage Monitors for the CPU Cores, Chipset
Voltage, +3.3V, +5V, +12V and +3.3V 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 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-defined 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 chassis temperature is too
high.

Chapter 1: Introduction

1-11

Introduction

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

This feature is available when used with Supero Doctor III in the Windows
OS environment or used with Supero Doctor II in Linux. SDIII is used to
notify the user of certain system events. 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.

.

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 both Win­dows 2000 and Windows NT 5.0.

Introduction

X6DH8-G2/X6DHE-G2 User's Manual

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
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

Chapter 1: Introduction

1-13

Introduction

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 X6DH8-G2/X6DHE-G2 can only accommodates 24-pin ATX power sup­plies. Although most power supplies generally meet the specifications re­quired by the CPU, some are inadequate. You should use one that will
supply at least 400W of power connector. In addition, the 12V 4-pin power
supply (J32) - is also required to ensure adequate power supply to the
system. Also your power supply must supply 1.5A for the Ethernet ports.

NOTE: The + 12V 8-pin Aux. Power Connector (J1D1) is also required
to support Intel Xeon CPUs. Failure to provide this extra power will
result in CPU PWR Failure. See Section 2-5 for details on connect­ing the power supply.

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.

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,

1-14

Introduction

X6DH8-G2/X6DHE-G2 User's Manual

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.

• 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.

2-2

X6DH8-G2/X6DHE-G2 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 (CEK) heat sink. To adequately support the weight of CPU heat
sinks, please install the X6DH8-G2/X6DHE-G2 in a chassis that is compliant
with the SSI EEB 3.5 Specification.

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.

!

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.)

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

X6DH8-G2/X6DHE-G2 User's Manual

To Un-install the Heatsink

1. Unscrew and remove the heatsink
screws from the motherboard in the
sequence as show in the picture on
the right.

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, 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.

(Caution! We do not recommend that the
CPU or the heatsink be removed. How­ever, if you do need to un-install the
heatsink, please follow the instructions
below to uninstall the heatsink to prevent
damage done to the CPU or the CPU
socket. )

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.

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
Bank 1. The memory scheme is interleaved so you must install two
modules at a time, beginning with Bank 1, then Bank 2, 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).
