2. FEATURES

2.1.3 Performance

• UltraPerformance: Onboard IDE Bus Master controller with two connectors that

support four IDE devices in two channels. Supports UltraDMA/66, UltraDMA/33
(IDE DMA Mode 2), PIO Modes 3 & 4, and supports Enhanced IDE devices, such
as DVD-ROM, CD-ROM, CD-R/RW , LS-120, and Tape Backup drives.

• Dual Speeds: CPU frequency can operate at either 133MHz or 100MHz.

• High-Speed Data Transfer Interface: IDE transfers using UltraDMA/33 Bus

Master IDE can handle rates up to 33MB/s. This motherboard with its chipset
and support for UltraDMA/66 doubles the UltraDMA/33 burst transfer rate to

66.6MB/s. UltraDMA/66 is backward compatible with both DMA/33 and DMA
and with existing DMA devices and systems so there is no need to upgrade
current EIDE/IDE drives and host systems. (UltraDMA/66 requires a 40-pin
80-conductor cable to be enabled and/or for UltraDMA Mode 4.)

• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-

ter buses to memory to CPU.

• RDRAM Optimized Performance: This motherboard supports the new gen-

eration memory , Rambus Dynamic Random Access Memory (RDRAM). While
PC100 SDRAM modules operate at 100MHz with a peak bandwidth of 0.8GB/s,
Rambus DRAMs can operate at up to 800MHz with a peak bandwidth of 1.6GB/s.

• ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also imple-

mented on all ASUS smart series motherboards. ACPI provides more Energy
Saving Features for future operating systems (OS) supporting OS Direct Power
Management (OSPM) functionality . W ith these features implemented in the OS,
PCs can be ready around the clock, yet satisfy all the energy saving standards.
To fully utilize the benefits of ACPI, an ACPI-supported OS, such as Windows
98, must be used.

• PC 99 Compliancy: Both the BIOS and hardware levels of the motherboard

meet PC 99 System Design requirements. The PC 99 requirements for systems
and components are based on the following high-level goals: support for Plug
and Play compatibility and power management for configuring and managing
all system components, and 32-bit device drivers and installation procedures for
Windows 95/98/NT. Color-coded connectors and descriptive icons make identi­fication easy as required by PC 99.

ASUS P3C-D User’s Manual

2. FEATURES

2.1.4 Intelligence

• Fan Status Monitoring and Alarm: To prevent system overheat and system

damage, the CPU, power supply, and system fans can be monitored for RPM
and failure. All the fans are set for its normal RPM range and alarm thresholds.

• Temperature Monitoring and Alert: To prevent system overheat and system

damage, this motherboard supports processor thermal sensing and auto-protec­tion.

• Voltage Monitoring and Alert: System voltage levels are monitored to ensure

stable current to critical motherboard components. Voltage specifications are
more critical for future processors, so monitoring is necessary to ensure proper
system configuration and management.

• System Resources Alert: T oday’s operating systems such as Windows 98, W in-

dows NT , and OS/2, require much more memory and hard drive space to present
enormous user interfaces and run large applications. The system resource moni­tor will warn the user before the system resources are used up to prevent pos­sible application crashes. Suggestions will give the user information on manag­ing their limited resources more efficiently.

• Dual Function Power Button: Through BIOS, the power button can be defined
as the “Stand by” (a.k.a. Suspend or Sleep) button or as the Soft-Off (see 25) A TX
Power / Soft-Off Switch Lead in 3.8 External Connectors for more information)
button. Regardless of the setting, pushing the power button for more than 4 sec­onds will enter the Soft-Off mode.

• Remote Ring On (requires modem): This allows a computer to be turned on
remotely through an internal or external modem. With this benefit on-hand, users
can access any information from their computers from anywhere in the world.

• Message LED (requires ACPI OS support): Message LEDs now act as infor-
mation providers. Through the way a particular LED illuminates, the user can
determine the stage the computer is in. A simple glimpse provides useful infor­mation to the user.

• Peripheral Power Up: Keyboard or Mouse power up can be enabled or dis-
abled through BIOS setup to allow the computer to be powered ON using your
keyboard or mouse click.

• Check Motherboard Settings

• Install Memory Modules

• Install the Central Processing Unit (CPU)

• Install Expansion Cards

• Connect Ribbon Cables, Panel Wires, and Power Supply

3.4 Motherboard Settings

WARNING! Computer motherboards and expansion cards contain very delicate

Integrated Circuit (IC) chips. To protect them against damage from static electric­ity, you should follow some precautions whenever you work on your computer.

1. Unplug your computer when working on the inside.

2. Use a grounded wrist strap before handling computer components. If you do
not have one, touch both of your hands to a safely grounded object or to a metal
object, such as the power supply case.

3. Hold components by the edges and try not to touch the IC chips, leads or con­nectors, or other components.

4. Place components on a grounded antistatic pad or on the bag that came with the

3.5 System Memory

NOTE: No hardware or BIOS setup is required after adding or removing memory.
This motherboard has three Rambus Inline Memory Module (RIMM) sockets. The

first two sockets (see Important notes for details) support Direct RDRAMs (both
ECC and non-ECC are supported) in 64, 96, 128, 192, 256, and 512MB densities for
a maximum of 1GB.

With the optional ASUS DR1 DIMM Riser, unbuffered Synchronous Dynamic Ran­dom Access Memory (SDRAM, 3.3V power level) in 64, 128 , 256, or 512MB densi­ties with Serial Presence Detect (SPD) can be used on the third socket for a maxi­mum of 1GB.

The chipset’s Error Checking and Correction (ECC) feature is available only when
using RDRAMs. ECC feature is not available when using SDRAM with an ASUS
DIMM Riser (ECC memory modules may still be used, but the ECC function will
not be available).

1. Depending on your configuration, a C-RIMM (Continuity RIMM) or CTRIMM,
or both must be used to complete the sockets that are not populated by either
RDRAMs or an ASUS DIMM Riser (when using SDRAM). C-RIMM is neces­sary to avoid breaking the signal lines, which are a serial connection in a Rambus
interface, such as used in this motherboard. CTRIMM is used to minimize sig­nal reflections or control the impedance at the end of the signal line. Both C­RIMM and CTRIMM assure the electrical integrity of a Rambus interface.

2. Pull out the port access cover and set it aside in case you need to cover the port
again when you decide to replace the riser with RDRAM.

3. Remove the riser from its static-proof bag.
NOTE: Hold the riser by its edges to avoid touching the connector or any deli-

cate components on the riser.

4. Align the notch keys in the riser with the small ribs inside the RIMM sockets
(see opposite page for locations of parts).

5. With the RIMM socket’s ejectors in the open position (as shown), push down gently
but firmly on the riser until it snaps into place. The guides on the socket’s ejectors
should go through the two mounting notches on the riser and the ejectors should
close. If necessary , push the ejectors inward to secure the riser in place.

NOTES:

• Do not rock the riser side to side. Rocking the riser can damage the RIMM
socket and the riser.

• Do not force the riser in. If you meet a lot of resistance, pull the riser out and
try again.

• T o see if the riser is properly connected, pull it gently. If it resists and stays
in place, it is connected. Make sure that you do not pull the riser so much
that you accidentally disconnect it.

3. HARDWARE SETUP

General DIMM Notes

• This motherboard only supports SPD DIMMs.

• SDRAM chips are generally thinner with higher pin density than EDO (Extended

Data Output) chips.

• BIOS shows SDRAM memory on bootup screen.

• Single-sided DIMMs come in 64,128, 256MB; double-sided come in 32, 64, 128,

256, 512MB.

• PC100-compliant modules must be used on the riser because of the strict timing
issues involved under this speed.

• The DIMMs must be 3.3V Unbuffered for this motherboard. To determine the
DIMM type, check the notches on the DIMMs (see figure below).

The notches on the DIMM module will shift between left, center, or right to identify
the type and also to prevent the wrong type from being inserted into the DIMM
socket on the riser. You must ask your retailer the correct DIMM type before pur­chasing. The riser supports four clock signals.
