1-2 Chipset Overview

Built upon the functionality and the capability of the Intel E8870 (870)
chipset, the i2DMR-8G2/i2DMR-iG2 motherboard provides the performance

Introduction

and feature set required for high-end server platforms with configuration
options optimized for communications, presentation, storage, computation or
database applications. The Intel E8870 chipset consists of the following
four primary components: the Scalable Node Controller (SNC), Server I/O
Hub (SIOH), the Memory Repeater Hub for Synchronous Double Data Rate
Memory(MRH_D) and Scalability Port Switch (SPS) (*Note Below). Comple­mentary components include the I/O Hub Controller (Intel ICH4), the Firm­ware Hub (FWH), and the PCI Bus Bridge (P64H2).

The major bus groups are:

Processor system bus: supporting up to two processors and one Scalable
Node Controller (SNC), with a maximum operating frequency of 200
MHz@400 MT/s.

Rambus and SNC Interface: the Interconnection between the SNC and
Memory Repeater Hub (MRH-D), operating at a maximum frequency of 400
MHz.

Synchronous DDR Interface: interface between the MRH-D and up to four
DIMM sockets, operating at the operating clock frequency of 100 MHz per
branch channel.

Scalability Port (SP) Interface: a 400MHz, double-pumped, simultaneous bi­directional signaling (SBD) interface.

Hub Interface 2.0: interface between the SIOH and the P64H2 using 266
MHz strobes on a 16-bit wide data bus.

Hub Interface 1.5: interface between the SIOH and the ICH4 using 133 MHz
strobes on a 8-bit wide data bus.

Local Firmware Hub (LPC): Interface between the SNC and local firmware.

System Management Bus (SMBus): a subset of the I2C serial bus integrated
into the SNC, SPS, and SIOH.

(*Note: The Scalability Port Switch-SPS is not used in the i2DMR-8G2/iG2.)

1-10

Chapter 1: Introduction

Complementary Components include:

I/O Controller Hub (ICH4)

The ICH4 is the fourth-generation I/O Controller Hub subsystem that inte­grates many of the input/output functions of the chipset, including a two­channel ATA100 Bus Master IDE controller. The ICH4 also interfaces with
PCI and various communications ports. Nearly all communications between
the GMCH and the ICH4 takes place over the hub Interface, which is a 66
MHz/266 MB/s bus.

P64H2 PCI-X Hub (P64H2)

The P64H2 PCI-X Hub provides a 16-bit connection to the MCH for high­performance I/O capability and two 64-bit PCI-X interfaces.

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 Last State.

Introduction

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER
i2DMR-8G2/i2DMR-iG2. All have an onboard System Hardware Monitor chip
that supports PC health monitoring.

Fan Status Monitor with Firmware/Software On/Off Control

The PC health monitor can check the RPM status of the cooling fans. The
onboard 3-pin chassis fans are controlled by the power management func­tions.

1-11

SUPER i2DMR-8G2/i2DMR-iG2 User's Manual

CPU Overheat LED and Control

This feature is available when the user enables the CPU overheat warning

Introduction

function in the BIOS. This allows the user to define an overheat tempera­ture. When this temperature is exceeded, fans will speed up, and the
warning LED is triggered.

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 1.1V to 1.5V (*sup­ported by VRMs only). This will allow the regulator to run cooler and thus
make the system more stable.

1-5 ACPI Features

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 SSI 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 i2DMR-8G2/i2DMR-iG2 requires a 24-pin connector and two 4­pin 12V/15A connectors for CPU VRMs. Although most power supplies
generally meet the specifications required by the CPU, some are inadequate.
You should use one that will supply at least 500W of power, and an even
higher wattage power supply is recommended for high-load configurations.
Also your power supply must supply 2A for the Ethernet ports and the
E8870 chipset.

It is strongly recommended that you use a high quality power supply that
meets SSI EPS 12V 1U 500W PS Specification. To verify the status of SSI
compliance, please visit the web site 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 recom-

1-12

Chapter 1: Introduction

mended 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 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.

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.

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 Itanium2 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.

Note: To optimize the functionality and capability of the i2DMR-8G2/
i2DMR-iG2, we recommend that i2DMR-8G2/i2DMR-iG2 be installed in
Supermicro chassis only.

Warning: The heatsink on the MRH-D chip has been pre-installed by the

manufacturer. Please do not touch it. Turning the heatsink in a wrong
way will damage it and will void the manufacturer's warranty.

A. Locating the components included in the shipping package
