Introduction
1-2 Chipset Overview
Built upon the functionality and the capability of the E7525 Tumwater
chipset, the X6DAR-8G/X6DAR-iG motherboard provides the performance
and feature set required for dual processor-based computer systems, with
configuration options optimized for communications, presentation, storage,
computation or database applications. The Intel E7525 Tumwater chipset
consists of the following components: the E7525 Tumwater Memory Controller Hub (MCH), the I/O Controller Hub (ICH5R), and the PCI-X Hub (PXH).
The E7525 Tumwater 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 DDR333/DDR266 with
a marched system bus address and data bandwidths of up to 2.7 GB/s
(DDR 333) per channel. The E7525 Tumwater also supports the new PCI
Express high speed serial I/O interface for superior I/O bandwidth. The MCH
provides configurable x16 PCI Express interfaces which may alternatively
be configured as two independent 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 ICH5R ICH I/O Controller Hub via HI 1.5 Hub Interface.
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.
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 2.3 Interface and
System Management Controller.
(*Notes: The CPU FSB speed is set at 800 MHz by the Manufacturer.
Please do not change the CPU FSB setting.)

Introduction
X6DAR-8G/X6DAR-iG 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 SUPER
X6DAR-8G/X6DAR-iG. 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.
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
Chapter 1: Introduction
1-11
Introduction
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.
Overheat/Fan Fail LED and Control
This feature is available when the user enables the Overheat/Fan Fail
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 autosense voltage IDs ranging from 0.8375V to 1.6V. This will allow the regulator to run cooler and thus make the system more stable.
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.
1-12
Introduction
X6DAR-8G/X6DAR-iG User's Manual
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
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.
Chapter 1: Introduction
1-13
Introduction
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 X6DAR-8G/X6DAR-iG 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.
(*Please refer to the next page for additional information.)
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.

Introduction
X6DAR-8G/X6DAR-iG User's Manual
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
X6DAR-8G/X6DAR-iG 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.
!
Socket lever
CPU Installation
1. Lift the lever on the CPU socket:
lift the lever to the upright
position as shown in the picture on
the right; otherwise, you will
damage the CPU socket when you
turn on the power. (Install CPU1
first.)
Pin 1
2. Insert the CPU in the socket and
make sure that pin 1 of the CPU
aligns with pin 1 of the socket
(both corners are marked with a
triangle). If only one CPU is used,
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* to make
sure that the CPU is securely
installed in the CPU socket.

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
due to the fact that 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 on the motherboard tray.

To Install:
Insert the
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 X6DAR-8G/X6DAR-iG supports up to 32/16 GB of Registered DDR-266/
333(PC2100/2700) 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. If Reg. ECC DDR 333 (PC2700)
memory modules are used, 4 pieces of double banked memory and 6 pieces
of single banked memory are supported.
