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 P8SC8/P8SCi motherboard. The P8SC8/P8SCi supports
single Intel Pentium® 4 Processor (the Prescott Processor) in the 775-Land
Grid Array Package (LGA 775) at a system bus speed of 800 MHz. The
Pentium 4 Processor in the 775-Land Grid Array Package is housed in a
Flip-Chip Land Grid Array (FC-LGA4) package that interfaces with the moth­erboard via an LGA775 socket. The package consists of a processor core
mounted on a substrate land-carrier. An integrated heat spreader (IHS) is
attached to the package substrate and core and serves as the contacting
surface for processor component thermal solutions, such as a heatsink.
Please refer to the motherboard specifications pages on our web site (http:/
/www.supermicro.com/Product_page/product-m.htm) for updates on sup­ported processors. This product is intended to be professionally installed.

Chapter 1: Introduction

1-2 Chipset Overview

Intel’s E7221 (Copper River) chipset, designed for the server market, con­sists of the following components: the Graphics Memory Controller Hub
(GMCH), Intel PCI-X Hub (PXH-V), and Intel I/O Controller Hub (ICH6R). The
E7221 (Copper River) chipset provides the performance and feature-set
required for the entry level single-processor server solutions.

Graphics Memory Controller Hub (GMCH)

The function of the GMCH is to manage the data flow between five inter­faces: Processor/Host interface (FSB), System Memory Interface (DRAM
controller), PCI Express Interface, Direct Media Interface (DMI) and PXH-V
Interface. The GMCH is optimized for the Prescott processors in an
LGA775 Package. It supports one or two channels of unbuffered, ECC/Non
ECC DDR2 533/400 SDRAM.

The ACPI component provides the data buffering and interface arbitration
required to ensure that system interfaces operate efficiently. The Direct
Media Interface (DMI) is a point-to-point interconnect between the Copper
River GMCH and the ICH6.

Intel ICH6R System Features

The I/O Controller Hub provides the I/O subsystem with access to the rest
of the system. Functions and capabilities include:

*PCI Express Base Specification, Rev. 1.0a-compliant
*PCI 2.3
*ACPI Power Management Logic Support
*USB host interface
*Enhanced DMA Controller
*System Management Bus
*Low Pin Count (LPC) Interface
*Firmware Hub (FWH) Interface

Graphics Features/Display

The Copper River GMCH provides an integrated server-quality onboard
graphics.

P8SC8/P8SCi User’s Manual

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the P8SC8/
P8SCi. The motherboard has an onboard System Hardware Monitor chip
that supports PC health monitoring.

Eight Onboard Voltage Monitors for the CPU Core, Chipset

++

Voltage, +3.3V,

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 define the sensi­tivity of the voltage monitor.

++

+5V,

+5V Standby, 1.5V, VBAT, and

++

++

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 define an overheat
temperature. When this temperature is exceeded or when a fan failure
occurs, then, the Overheat/Fan Fail warning LED is triggered.

±±

±12V

±±

Auto-Switching Voltage Regulator for the CPU Core

The 3-phase-switching voltage regulator for the CPU core can support up to
60A current and auto-sense voltage IDs ranging from 0.875 V to 1.6V. This
will allow the regulator to run cooler and thus make the system more stable.

1-4 CPU Thermal Management

Thermal Management 2 (TM2)

When TM2 is enabled in the BIOS and the CPU temperature reaches a pre­defined threshold, a thermal monitoring mechanism will reduce the process
speed by lowering the bus-to-core ratio of the processor core clock and

decrease the voltage input by changing the CPU VID. This combination of
reduced CPU bus frequency and CPU VID effectively decreases CPU power

1-10

Chapter 1: Introduction

consumption to prevent processor overheat from happening and thus,
greatly increases system stability. (*This function is available for the CPUs
that support TM2.)

1-5 Power Configuration Settings

This section describes 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 the USB keyboard is the only keyboard in the system, it keyboard 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 (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 access tracking can occur after hours and on weekends so that
daily LAN traffic is kept to a minimum and users are not interrupted. The

1-11

P8SC8/P8SCi User’s Manual

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.

Wake-On-Ring (WOR) Header

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 of 1 GHz and faster.

The P8SC8/P8SCi accommodates 12V ATX power supplies. Al­though most power supplies generally meet the specifications required by
the CPU, some are inadequate. A 2 amps of current supply on a 5V Standby
rail is strongly recommended.

It is strongly recommended that you use a high quality power supply that
meets 12V ATX power supply Specification 1.1 or above. 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.

*Warning: Do not use a wrong type of onboard CMOS battery or
install the onboard CMOS battery upside down to avoid any
possible explosion.

1-12

Chapter 1: Introduction

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 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 provides functions that comply with ACPI (Advanced Con­figuration 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 flexibly
adjusted 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.

• Use only the correct type of CMOS onboard battery as specified by the
Manufacturer. Do not install the CMOS onboard battery upside down to
avoid 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 for full installation of the mother­board into a chassis:

1. Install the processor and the heatsink to the motherboard.

2. Install the motherboard in the chassis.

3. Install the memory and add-on cards.

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

3. Locate Pin 1 on the CPU socket.

(*Note: Pin 1 is the corner marked
with a triangle). Please note that the
North Key and the South Key are
located vertically in the CPU housing.

4. Position the motherboard in such a

way that Pin 1 of the CPU socket is
located at the left bottom of the CPU
housing.

5. Use your thumb and your index

finger to hold the CPU at the North
Center Edge and the South Center
Edge of the CPU.

6. Align Pin 1 of the CPU with Pin 1 of

the socket. Once aligned, carefully
lower the CPU straight down to the
socket. (**Do not drop the CPU on
the socket. Do not move the CPU
horizontally or vertically. Do not rub
the CPU against the surface of the
socket or against any pins of the
socket to avoid damage to the CPU
or the socket.)

7. With the CPU inside the socket,

inspect the four corners of the CPU to
make sure that the CPU is properly
installed.

8. Use your thumb to gently press the

lever down and lock it in the hook.

9. If the CPU is properly installed into

the socket, the plastic cap will be
automatically released from the load
plate when the lever is pushed into the
hook. Remove the plastic cap from the
motherboard.

Installation of the Heatsink

1. Locate the CPU Fan on the
motherboard. (Refer to the layout
on Page 1-4 for the CPU Fan
location.)

2. Position the heatsink in such a
way that the heatsink fan wires
are closest to the CPU fan and
are not interfered with other
components

3. Inspect the CPU Fan wires to
make sure that the wires are routed
through the bottom of the heatsink.

4. Remove the thin layer of the
protective film from the copper core
of the heatsink.

(*Warning: CPU overheat may occur
if the protective film is not removed
from the heatsink.)

5. Apply the proper amount of
thermal grease on the CPU. (*Note:
if your heatsink came with a
thermal pad, please ignore this
step.)

6. If necessary, rearrange the
wires to make sure that the wires
are not pinched between the
heatsink and the CPU. Also make
sure to keep clearance between the
fan wires and the fins of the
heatsink.

7. Align the four heatsink fasteners
with the mounting holes on the
motherboard. Gently push the
fasteners into the mounting holes
until you hear a "click".

8. Repeat Step 6 to insert all four

heatsink fasteners into the mounting
holes.

9. Once all four fasteners are

securely inserted into the mounting
holes and the heatsink is properly
installed on the motherboard, connect
the heatsink fan wires to the CPU Fan
connector.

Heatsink Removal

1. Unplug the power cord from the

power supply.

2. Disconnect the heatsink fan wires

from the CPU fan header.

3. Use your finger tips to gently press

on the fastener cap and rotate counter­clockwise to make a 1/4 (900) turn.

Chapter 2: Installation

4. Repeat Step 3 to loosen all fasteners

from the mounting holes.

5. With all fasteners loosened, remove

the heatsink from the CPU.

2-3 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. (*Note: some com­ponents are very close to the mounting holes, please take caution to pre­vent damage done to these components when installing the motherboard
into the chassis.)

2-4 Installing DDR2 Memory

CAUTION

Exercise extreme care when installing or removing memory

modules to prevent any possible damage.

Memory Module Installation (See Figure 2-2)

1. Insert each DDR2 memory module vertically into its slot. Pay attention
to the notch along the bottom of the module to prevent inserting the
module incorrectly. (See support information below.)

2. Gently press down on the memory module until it snaps into place.

Support

The P8SC8/P8SCi supports Dual channel, ECC/Non ECC, unbuffered
DDR2 533/ 400 SDRAM. Both interleaved and non-interleaved memory
are supported, so you may populate any number of DIMM slots. (Popu­lating DIMM#1A, DIMM#2A, and/or DIMM#1B, DIMM#2B with memory
modules of the same size and of the same type will result in dual
channel, two-way interleaved memory which is faster than single
channel, non-interleaved memory.)

To Install:

Insert module
vertically and
press down
until it snaps
into place.
Pay attention
to the notch.

To Remove:

Use your thumbs
gently to push
each release tab
outward to
release the DIMM
from the slot.
