Static Electricity Precautions

Components on this mainboard can be damaged by static electricity. Take the following precautions when unpacking the mainboard and installing it in a system.

Keep the mainboard and other components in their original static-proof packaging until you are ready to install them.

During installation, wear a grounded wrist strap if possible. If you dont have a wrist strap, discharge static electricity by touching the bare metal of the system chassis.

Handle the mainboard carefully by the edges. Avoid touching the components unless it is absolutely necessary. During installation put the mainboard on top of the static-protection packaging it came in with the component side facing up.

Pre-Installation Inspection

Inspect the mainboard for damage to the components and connectors on the board.

If you suspect that the mainboard has been damaged, do not connect power to the system. Contact your mainboard vendor and report the damage.

To install this mainboard in a system, please follow these instructions in this chapter:

q       Identify the mainboard components

q       Install a CPU

q       Install one or more system memory modules

q       Make sure all jumpers and switches are set correctly

q       Install this mainboard in a system chassis (case)

q       Connect any extension brackets or cables to connecting headers on the mainboard

q       Install other devices and make the appropriate connections to the mainboard connecting headers

Note:

Before installing this mainboard, make sure jumper JP2 is under Normal setting. See this chapter for information about locating JP2 and the setting options.

Never connect power to the system during installation; otherwise, it may damage the mainboard.

Mainboard Components

This diagram below identifies major components on the mainboard.

Note: Any jumpers on your mainboard that do not appear in the illustration above are for testing only.

I/O Ports

Install A CPU

This mainboard has a Socket-462 CPU socket for AMD K7 processors.

To ensure reliability, ensure that your processor has a heatsink/cooling fan assembly.

Do not try to install a Socket-370/Socket-7 processor in the Socket-462. A Socket-370/Socket-7 processor such as the PPGA Celeron, FCPGA Pentium-III, Pentium-MMX, or the AMD K5/K6 does not fit in the Socket-462.

The following list notes the processors that are currently supported by this mainboard.

Athlon XP: 2000+ and up; FSB: 266 MHz

Athlon: 650 MHz~1.4 GHz, FSB: 200 MHz, 266 MHz

Duron: 550 MHz~1.2 GHz, FSB: 200 MHz

Installing a Socket-462 Processor

A processor installs into the ZIF (Zero Insertion Force) Socket-462 on the mainboard.

Locate the Socket-462 and CPUFAN1. Pull the locking lever out slightly from the socket and raise it to the upright position.

On the processor, identify the Pin-1 corner by its beveled edge.

On the Socket-462, identify the Pin-1 corner. The Pin-1 corner is at the top of the locking lever when it locked.

Match the Pin-1 corners and insert the processor into the socket. No force is required and the processor should drop into place freely.

Swing the locking lever down and hook it under the catch on the side of the socket. This secures the CPU in the socket.

All processors should be installed with a combination heatsink/cooling fan (the original fan is recommended, the others fan is not), connect the cable from the fan to the CPU fan power connector CPUFAN1.

See the Setting Jumper Switches section for detail information on CPU System Bus settings.

Install Memory

This mainboard accommodates 168-pin 3.3V/184-pin 2.5V unbuffered SDRAM/DDR SDRAM (Double Data Rate SDRAM) memory modules. The memory chips must be standard or registered SDRAM (Synchronous Dynamic Random Access Memory).

You must install at least one memory module in order to work the mainboard, either SDRAM or DDR SDRAM, but you cannot work them simultaneously.

SDRAM provides 800 MB/s or 1 GB/s data transfer rate corresponding with the bus 100 MHz or 133 MHz. It doubles the rate to 1.6 GB/s and 2.1 GB/s by transferring data on both the rising and falling edges of the clock. DDR SDRAM uses additional power and ground lines and requires 184-pin 2.5V unbuffered DIMM module reather than the 168-pin 3.3V unbuffered DIMMs used by SDRAM.

Installation Procedure

The mainboard accommodates two memory modules. You must install at least one module of them. Each module can be installed with up to 2 GB system memory.

Install the memory modules as the following steps:

Push the latches on each side of the DIMM socket down.

Align the memory module with the socket. The DIMM sockets are keyed with notches and the DIMMs are keyed with cutouts so that they can only be installed correctly.

Check that the cutouts on the DIMM module edge connector match the notches in the DIMM socket.

Install the DIMM module into the socket and press it firmly down until it is seated correctly. The socket latches are levered upwards and latch on to the edges of the DIMM.

Install any remaining DIMM modules.

Setting Jumper Switches

Jumpers are sets of pins connected together with jumper caps. The jumper caps change the mainboards operation by changing the electronic circuits on the mainboard. If we connect two pins with a jumper cap, these pins are SHORT; if remove a jumper cap from these pins, they are OPEN.
