2. HARDWARE SETUP

2.1 Getting Started

IMPORTANT: Due to Pentium 4 CPU’s power consumption requirement, an

ATX12V power supply is recommended for this motherboard. For typical system configurations, an ATX12V power supply that can supply at least 230W and at least

8.5A on the +12V lead is required. For heavily-loaded configurations, an ATX12V power supply that can supply at least 300W is required.

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

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 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.

WARNING! Make sure that you unplug your power supply when adding or

removing system components. Failure to do so may cause severe damage to your motherboard, peripherals, and/or components. The onboard LED when lit acts as a reminder that the system is in suspend or soft-off mode and not powered OFF.

2. HARDWARE SETUP

2.2 System Memory

NOTE: No hardware or BIOS setup is required after adding or removing memory . This motherboard has four 184-pin Rambus Inline Memory Modules (RIMM) sockets.

These sockets support 64Mbit, 128Mbit, and 256Mbit Direct RDRAM technologies.

TOT AL SYSTEM MEMOR Y =

(2GB Max)

IMPORTANT

1. The memory configuration of channel A (RIMMA1 and RIMMA2) and channel B (RIMMB1 and RIMMB2) must be identical (see below).

2. C-RIMMs (Continuity RIMM) must be used to complete the sockets that are not populated by RDRAMs. A 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. This assures the electrical integrity of a Rambus interface.

3. When C-RIMMs are required, it is recommended that they be inserted into RIMMA2 and RIMMB2.

2. HARDWARE SETUP

2.2.1 Installing Memory

The memory module (RIMM/C-RIMM) will fit in only one orientation.

IMPORTANT: Do not touch the memory module’s connectors. Handle the mod-

ule only by the edges.

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

ule in place.

Removing Memory

T o release a memory module, push both ejectors outward and pull the module straight up and out of the RIMM sockets.

WARNING! RIMM modules become extremely hot during operation. To re-

duce the risk of personal injury from hot surfaces, allow the modules to cool off before removing them.

2. HARDWARE SETUP

2.3 Central Processing Unit (CPU)

The motherboard provides a ZIF Socket for the P4 CPU. The CPU that came with the motherboard should have a fan attached to it to prevent overheating. If this is not the case, then purchase a fan before you turn on your system.
