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
H8DGT-HF/HIBQF serverboards.

The H8DGT-HF/HIBQF serverboard is based on the AMD® SR5670/SP5100
chipset and supports dual AMD Socket G34 type processors with up to 128 GB of
ECC/Non-ECC UDIMM or up to 512 GB of ECC RDIMM/LRDIMM
DDR3-1600/1333/1066 MHz SDRAM in 16 DIMMs. The only difference between
the serverboards is that the H8DGT-HIBQF serverboard has a Mellonox Connect-X2
Infi niBand® QSFP connector and the H8DGT-HF does not.

Please refer to the motherboard specifi cations pages on our web site for updates on
supported processors (http://www.supermicro.com/aplus/). This product is intended
to be professionally installed.

Manual Organization

Chapter 1 includes a checklist of what should be included in your motherboard

box, describes the features, specifi cations and performance of the motherboard
and provides detailed information about the chipset.

Chapter 2 begins with instructions on handling static-sensitive devices. Read this
chapter when installing the processor(s) and memory modules and when installing
the motherboard in a chassis. Also refer to this chapter to connect the hard disk
drives, the various ports, and the power and reset buttons and the system LEDs.

If you encounter any problems, see Chapter 3, which describes troubleshooting
procedures for the video, the memory and the setup confi guration stored in CMOS.

actual specifi cations of your motherboard.

Chapter 1: Introduction

1-9

1-3 Chipset Overview

The H8DGT-HF/HIBQF serverboard is based on the AMD SR5670/SP5100
chipset. This chipset functions as a Media and Communications Processor (MCP).
Controllers for the system memory are integrated directly into AMD Opteron
processors.

AMD SR5670/SP5100 Chipset

The AMD SR5670/SP5100 are each a single-chip, high-performance HyperT ransport
peripheral controller. It includes a 30-lane PCI Express interface, an AMD Opteron
16-bit Hyper Transport interface link, a six-port Serial ATA interface and a fi ve-port
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.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the H8DGT-HF/HIBQF
serverboard. The serverboard has an onboard System Hardware Monitor chip that
supports PC health monitoring.

Onboard Voltage Monitors

The onboard voltage monitor will continuously scan crucial voltage levels. 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 monitor. 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.

1-10

H8DGT-HF/HIBQF Serverboard User’s Manual

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, the Overheat/Fan Fail
warning LED is triggered.

Auto-Switching Voltage Regulator for the CPU Core

The 6-phase-switching voltage regulator for the CPU core can support up to
AMD Opteron 6000SE series processors. This will allow the regulator to run cooler
and thus make the system more stable.

1-5 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

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 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.

Chapter 1: Introduction

1-11

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 H8DGT-HF/HIBQF serverboard requires the use of proprietary power supplies.
Please refer to the pinout information for the power connectors in Section 6 of
Chapter 2 for detailed information on power requirements.

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.

1-7 Super I/O

The Super I/O includes 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 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 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 and APM (Advanced Power
Management).
