3.3 Hardware Setup Procedure

Before using your computer, you must complete the following steps:

• 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

This section explains in detail how to change your motherboard’s function settings
through the use of switches and/or jumpers.

WARNING! Computer motherboards and expansion cards contain very delicate Inte-

grated 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 compo­nent whenever the components are separated from the system.

5. Ensure that the ATX power supply is switched off before you plug in or remove the
ATX power connector on the motherboard.

Motherboard Feature Settings (DSW)

Besides jumper settings, some of the motherboard’ s onboard functions are adjusted
through the DIP switches. The white block represents the switch’s position. The

5) CPU External Frequency Setting (DSW)

This option tells the clock generator what frequency to send to the CPU, SDRAM,
and the chipset. This allows the selection of the CPU’ s External frequency. The
CPU External Frequency multiplied by the Frequency Multiple equals the CPU’ s
Internal frequency (the advertised CPU speed). The CPU is running at the same
speed as the SDRAM.

NOTE: To use this feature, CPU Frequency Selection in BIOS setup must be
set to [By Jumper] (see 4.4.2 Advanced Chipset Setup).

3.5 System Memory (DIMM)

NOTE: No hardware or BIOS setup is required after adding or removing memory.
This motherboard uses only Dual Inline Memory Modules (DIMMs). S ockets are

available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Ac-
cess Memory (SDRAM) of 16, 32, 64, 128MB, or 256MB. to form a memory size
between 16MB and 768MB. One side (with memory chips) of the DIMM takes up
one row on the motherboard.

To use the chipset’s Error Checking and Correction (ECC) feature, you must use a
DIMM with 9 chips per side (standard 8 chips/side + 1 ECC chip).

Memory speed setup is recommended through Configure SDRAM T iming by SPD
(see 4.4.2 Advanced Chipset Setup).

Install memory in any combination as follows:

System Memory

3. H/W SETUP

IMPORTANT: DIMMs must be inserted in the following sequence: DIMM1,

DIMM2, DIMM3. That is, if you intend to initially use one DIMM, use DIMM1
first. Then when you are ready for a second DIMM, use DIMM2, and so on. If
this sequence is not followed, system instability may be experienced.

DIMM3 (Rows 4&5) SDRAM 16, 32, 64, 128, 256MB x1

NOTE: At the time this User’s Manual was written, 256MB DIMM’s are only
available as Double-Sided registered memory (128Mbit cells).

3.5.1 General DIMM Notes

• When this motherboard operates at 100MHz, PC100-compliant modules must

Total System Memory (Max 768MB) =

be used because of the strict timing issues involved under this speed.

• This motherboard supports SPD (Serial Presence Detect) DIMMs. This is the
memory of choice for best performance vs. stability.

• 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 16, 32, 64,128MB; double-sided come in 32, 64,
128, 256MB.

3.5.2 DIMM Memory Installation

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 shown. DIMM mod­ules are longer and have different pin contact on each side and therefore have a
higher pin density. SIMM modules have the same pin contact on both sides.
