Chapter 1: Introduction

1-2 Chipset Overview

The H8SMU motherboard is based on the nVidia MCP55 Pro chipset. The nVidia
MCP55 Pro functions as Media and Communications Processor (MCP). Controllers
for the system memory are integrated directly into the AMD Opteron processor.

MCP55 Pro Media and Communications Processor

The MCP55 Pro is a single-chip, high-performance HyperTransport peripheral con­troller. It includes a 28-lane PCI Express interface, an AMD Opteron 16-bit Hyper
Transport interface link, a four-port Serial ATA interface, a dual-port Gb Ethernet
interface, a single ATA133 bus master interface and a USB 2.0 interface. This hub
connects directly to the CPU.

HyperTransport Technology

HyperTransport technology is a high-speed, low latency point to point link that was
designed to increase the communication speed by a factor of up to 48x between
integrated circuits. This is done partly by reducing the number of buses in the
chipset to reduce bottlenecks and by enabling a more effi cient use of memory in
multi-processor systems. The end result is a signifi cant increase in bandwidth
within the chipset.

H8SMU User’s Manual

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the H8SMU. The
motherboard has an onboard System Hardware Monitor chip that supports PC
health monitoring.

Onboard Voltage Monitors for CPU core, 3.3V, +5Vin, +12Vin,
+5V standby and battery voltage

The onboard voltage monitor will scan these voltages continuously . Once a voltage
becomes unstable, it will give a warning or send an error message to the screen.
Users can adjust the voltage thresholds to defi ne the sensitivity of the voltage moni-
tor. Real time readings of these voltage levels are all displayed in BIOS.

Fan Status Monitor with Firmware/Software Speed Control

The PC health monitor can check the RPM status of the cooling fans. The onboard
fans are controlled by thermal management via BIOS.

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 defi ne 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 5-phase-switching voltage regulator for the CPU core can support up to 100A
and auto-sense voltage IDs. This will allow the regulator to run cooler and thus
make the system more stable.

1-10

Chapter 1: Introduction

1-4 Power Confi guration Settings

This section describes the features of your motherboard that deal with power and
power settings.

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.

BIOS Support for USB Keyboard

If a USB keyboard is the only keyboard in the system, it will function like a normal
keyboard during system boot-up.

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function as a system
suspend button. When the user depresses the power button, the system will 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. The power
will turn off and no power will be provided to the motherboard.

Wake-On-LAN (JWOL)

Wake-On-LAN is defi ned as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, up-dates and access
tracking can occur after hours and on weekends so that daily LAN traffi c is kept to
a minimum and users are not interrupted. The motherboard has a 3-pin header
(JWOL) 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.

1-11

H8SMU User’s Manual

Wake-On-Ring Header (JWOR)

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.

1-5 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 H8SMU accommodates 12V ATX power supplies. Although most power sup­plies generally meet the specifi cations required by the CPU, some are inadequate.
Important: a 3A or greater current supply on the 5V Standby rail is required.

It is strongly recommended that you use a high quality power supply that meets
12V ATX power supply Specifi cation 1.1 or above. Additionally, in areas where
noisy power transmission is present, you may choose to install a line fi lter 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.

Warning: To prevent the possibility of explosion, do not use the wrong type of
onboard CMOS battery or install it upside down.

Chapter 1: Introduction

1-6 Super I/O

The disk drive adapter functions of the Super I/O chip include a fl oppy 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 fl oppy disk drives. The Super I/O supports two 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 Confi guration
and Power Interface), which includes support of legacy and ACPI power manage­ment through a 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 be fl exibly adjusted
to meet ISA PnP requirements, which support ACPI.

2-1 Static-Sensitive Devices

Electrostatic Discharge (ESD) can damage electronic com ponents. T o prevent dam­age to your system board, it is important to handle it very carefully. The following
measures are generally suffi cient 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 CMOS onboard battery as specifi ed by the manufac-
turer. Do not install the CMOS onboard battery upside down, which may result
in a 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.

Installation Procedures

Follow the procedures as listed below to install the motherboard into a chassis:

1. Install the processor(s) and the heatsink(s).

2. Install the motherboard in the chassis.

3. Install the memory and add-on cards.

4. Finally, connect the cables and install the drivers.

2-2 Processor and Heatsink Installation

Exercise extreme caution when handling and installing the proces­sor. Always connect the power cord last and always remove it be­fore adding, removing or changing any hardware components.

CPU Backplates

A CPU backplate (BKT-0017L) has been included in the retail box. The backplate
prevents the CPU area of the motherboard from bending and provides a base for
attaching the retention module. To install, the backplate, begin by peeling off the
release paper to expose the adhesive. On the underside of the motherboard,
locate the two holes on either side of the CPU socket. Attach the adhesive side
of the backplate to the board by inserting the standoffs into the two holes and
applying light pressure so that the backplate sticks to the underside of the board.
See Figure 2-1.

Installing the Processor

1. Lift the lever on CPU socket until it
points straight up.

2. Use your thumb and your index fi n-
ger to hold the CPU. Locate pin 1 on
the CPU socket and pin 1 on the CPU.
Both are marked with a triangle.

3. Align pin 1 of the CPU with pin 1
of the socket. Once aligned, carefully
place the CPU into the socket. Do not

drop the CPU on the socket, move the
CPU horizontally or vertically or rub the
CPU against the socket or against any
pins of the socket, which may damage
the CPU and/or the socket.

Triangles

2-2

4. With the CPU inserted into the
socket, inspect the four corners of the
CPU to make sure that it is properly
installed and fl ush with the socket.

5. Gently press the CPU socket lever
down until it locks in the plastic tab.

Chapter 2: Installation

Installing the Heatsink Retention Modules

A heatsink retention module (BKT-0018L) and two screws have been included in
the retail box. Once installed, it is used to help attach the heatsink to the CPU.
To install, position the module so that the CPU backplate standoffs insert through
the holes on the heatsink retention module and the four feet on the module contact
the motherboard. Secure the retention module to the backplate with two of the
screws provided. See Figure 2-1. Note: BKT-0018L is included for use with non­Supermicro heatsinks only. When installing Supermicro heatsinks, only BKT-0017L
(CPU backplate) is needed. BKT-0018L was designed to provide compatibility with
clip-and-cam type heatsinks from third parties.
