Chapter 1: Introduction

1-2 Chipset Overview

Built upon the functionality and capabilities of the E7525 chipset, the X6DAT­G/X6DAi-G motherboard provides the performance and feature set required
for dual processor-based computer systems, with configuration options
optimized for communications, presentation, storage, computation and data­base applications. The Intel E7525 chipset consists of the following compo­nents: the Memory Controller Hub (MCH), and the I/O Controller Hub (6300
ESB ICH).

MCH

The MCH supports single or dual Xeon EM64T processors with a Front Side
Bus speed of 800 MHz*. Its memory controller provides direct connection to
two channels of registered DDR333 with a marched system bus address
and data bandwidths of up to 2.67 GB/s (DDR333) per channel. The MCH
also supports the new PCI Express high speed serial I/O interface for supe­rior I/O bandwidth and provides configurable x16 and x8 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 6300ESB ICH I/O Controller Hub via HI

1.5 Hub Interface to support 32-bit or 64-bit PCI devices running at 33 or 66
MHz.

Introduction

6300 ESB (Hance Rapids) ICH System Features

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

The 6300 ESB Hance Rapids ICH I/O Controller Hub integrates: 2-channel
Ultra ATA/100 Bus Master IDE Controller, two Serial ATA (SATA) Host Con­trollers, SMBus 2.0 Controller, LPC/Flash BIOS Interface, PCI-X (66MHz) In­terface, PCI 2.2 Interface and System Management Controller.

*Note: The CPU FSB speed is set at 800 MHz by the Manufacturer.
Please do not change the this setting.

X6DAT-G/X6DAi-G User's Manual

1-3 Special Features

Introduction

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 Last State.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER
X6DAT-G/X6DAi-G. 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 Fan Speed Control

The PC health monitor can check the RPM status of the cooling fans. The
onboard 4-pin CPU and chassis fans are controlled by the thermal manage­ment functions under in the BIOS.

Environmental Temperature Control via Supero Doctor III

The thermal control sensor monitors the CPU temperature in real time and
will trigger the fan to speed up 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 trigger the fan to speed up to prevent any overheat damage to

1-10

Chapter 1: Introduction

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/Fan Fail LED and Control

This feature is available when the user enables the CPU overheat/Fan Fail
warning function in the BIOS. This allows the user to define an overheat
temperature. When this temperature is exceeded or when a fan failure
occurs, then, the Overheat/Fan Fail warning LED is triggered.

Auto-Switching Voltage Regulator for the CPU Core

The auto-switching voltage regulator can auto-detect and regulate power
supply to the CPU. This will allow the regulator to run cooler and thus make
the system more stable.

TM2/CPU VRM Overheat

When the CPU reaches 900 C and above (Overheat), the CPU will slow down
and CPU Voltage will decrease to reduce CPU power consumption and VRM
heat dissipation.

When CPU temperature reaches 900 C and above (*Default), the system will
go into the throttling state. The Overheat LED and Alarm Buzzer will be
turned on. The CPU wii slow down. When this happens, you can go to the
Health Monitor Setting in the BIOS to reset CPU Overheat Temperature.

Introduction

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

1-11

X6DAT-G/X6DAi-G User's Manual

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.

Introduction

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
2000, Windows NT 5.0, Windows XP and Windows Server 2003.

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into the suspend state, the chassis power LED will
start blinking to indicate that the CPU is in the 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 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 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 (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.

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.

1-12

Chapter 1: Introduction

The SUPER X6DAT-G/X6DAi-G accommodates 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. A 12V 8-pin power connection (at J1D1) is required

for CPU power consumption, and an additional 12V 4-pin power
connection (J32) is also recommended for heavy load configura­tions.) Also your power supply must supply 1.5A for the Ethernet ports. 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). 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.

Introduction

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.

Installation

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 as specified by the
manufacturer. Do not install the onboard 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.

2-1

X6DAT-G/X6DAi-G User's Manual

2-2 Xeon EM64T 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.

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. 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*. This
means that the CPU is securely
installed in the CPU socket.

(*Heatsinks are heavy. Please handle with care.)

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 tight-

ening all four screws.

Mounting the Motherboard in the Chassis

All motherboards have standard mounting holes to fit different types of
chassis. Make sure that the locations 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 that the
metal standoffs click in or are screwed in tightly. Then use a screwdriver
to secure the motherboard onto the motherboard tray.

2-3 Installing DIMMs

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

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 of the same memory type and of the same memory speed 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 X6DAT-G/X6DAi-G supports up to 16 GB of ECC registered DDR333 or
up to 32 GB of ECC registered DDR266 SDRAM memory. Both motherboards
were designed to support 4 GB modules in each slot, but have only been
verified for up to 2 GB modules. (*When Registered ECC DDR333-PC2700
memory modules are used, we recommend that up to four double-banked
memory modules be installed on the motherboard.)

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.

2-5

X6DAT-G/X6DAi-G User's Manual

To Remove:

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