ASUS Smart Series of Motherboards
Performance
•SDRAM Optimized Performance — ASUS Smart series of motherboards sup-
port the new generation memory, Synchronous Dynamic Random Access
Memory (SDRAM).
•Double the IDE Transfer Speed — ASUS Smart series of motherboards with
SiS5591 chipset improves IDE transfer rate using Bus Master UltraDMA/33
IDE which can handle data transfer up to 33MB/s. This technology is also compatible with existing ATA-2 IDE specs so there is no need to upgrade current
hard drives or cables.
•ACPI Ready — ACPI (Advanced Configuration and Power Interface) is also
implemented on all ASUS Smart series of motherboards. ACPI provide more
Energy Saving Features for the future operating systems (OS) supporting OS
Direct Power Management (OSPM) functionality. With these features implemented in the OS, PCs can be ready around the clock everyday, yet satisfy all
the energy saving standards. To fully utilize the benefits of ACPI, an ACPIsupported OS such as in the next release of Windows 95 must be used.
Smart Series
II. FEATURES
•PC97 Compliant — Both the BIOS and hardware levels of ASUS Smart series
of motherboards meet PC97 compliancy . The new PC 97 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 both Windows 95 (and its successors) and Windows NT.
Intelligence:
•Fan Status Monitoring and Alarm — To prevent system overheat and system
damage, the CPU and chassis fans are monitored for RPM and failure. The normal RPM range and alarm thresholds of these fans can be set through hardware
monitoring software.
•Temperature Monitoring and Alert — To prevent system overheat and sys-
tem damage, there is a heat sensor under the CPU and on the motherboard itself
to monitor CPU and system temperature to make sure the system is operating at
a safe heat level to avoid any failures triggered by extremely high temperature.
ASUS SP98AGP-X User’s Manual9
II. FEATURES
Smart Series
II. FEATURES
•Voltage Monitoring and Alert — System voltage levels are monitored to en-
sure 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 — Today’s operating systems such as Windows 95,
Windows 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.
•CPU Slow Down — If the CPU fan malfunctions, the system will deactivate the
CPU Clock line to decrease CPU utilization to the speed upon detection of system overheat. This will prevent CPU damage from system overheat. The CPU
utilization will restore normal operations when temperature falls below a safe
level.
•Auto Fan Off — The system fans will power off automatically even in sleep
mode. This function reduces both energy consumption and system noise, and
is a important feature to implement silent PC systems.
•Remote Ring On (requires A TX power supply) — This allows a computer to
be turned on remotely through a modem. W ith this benefit on-hand, any user can
access vital information from their computer from anywhere in the world!
•Message LED — Chassis LEDs now act as information 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.

connection, connect pins 1&2, and connect pins 2&3 respectively . Pin 1 for our motherboards is always on top
the keyboard connector away from yourself. A “1” is written besides pin 1 on jumpers
with three pins. The jumpers will also be shown graphically such as to connect
pins 1&2 and to connect pins 2&3. Jumpers with two pins will be shown as
for Short (On) andfor Open (Off). For manufacturing simplicity, the jumpers may be sharing pins from other groups. Use the diagrams in this manual instead of
following the pin layout on the board. Settings with two jumper numbers require that
both jumpers be moved together. To connect the pins, simply place a plastic jumper
cap over the two pins as diagramed.
WARNING!Computer motherboards, baseboards and components, such as SCSI
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.

Only Dual Inline Memory Modules (DIMMs) can be used with this motherboard.
Three sockets are available for 3.3Volt (power level) Unbuffered Synchronous
DRAMs (SDRAMs; 8, 16, 32, 64, or 128MB) or EDO DRAM (8, 16, 32, 64, 128, or
256MB) to form a memory size between 8MB to 768MB. One side (with memory
chips) of the DIMM module takes up one Row on the motherboard. If ECC-supported DIMM is used, you can enable the ECC function through BIOS setup –
CHIPSET FEATURES SETUP “Data Integrity Mode.”
IMPORTANT: You must first set the memory speed through the “EDO/FPM Con-
figuration” under the BIOS Chipset Setup of the BIOS SOFTWARE.
WARNING:Memory modules must have 18 chips or less. Memory modules with
more that 18 chips will cause unstable operation.
ASUS DIMM Module Examples:

System Memory
III. INSTALLATION
General DIMM Notes: (not true for all memory modules)
• Four possible memory chips are supported: EDO or SDRAM with and without parity.
• SDRAM chips are generally thinner with higher pin density than EDO chips.
• BIOS shows EDO or SDRAM memory on bootup screen.
• 8 chip/side modules do not support parity, only 9 chip/side modules support parity.
• Single sided modules are usually 16 or 64 MB, double sided are usually 8, 32, or 128MB.

III. INSTALLATION
DIMM Memory Installation Procedures:
Insert the module(s) as shown. Because the number of pins are different on either
side of the breaks, the module will only fit in the orientation as shown. DRAM
SIMM modules have the same pin contact on both sides. SDRAM DIMM modules
have different pin contact on each side and therefore have a higher pin density.
