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 electric-  
ity, 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 con-  
nectors, 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.

IMPORTANT  
1. The memory configuration of channelA(RIMMA1 and RIMMA2) and chan-  
nel 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 modules connectors. Handle the mod-  
ule only by the edges.

WMT-LX 184-Pin RIMM Sockets  
1. Make sure that the notch keys in the module are aligned with the small ribs  
inside the RIMM sockets.

EJECTOR  
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 sockets  
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  
To 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.
