Introducing the Mainboard

IInnttrroodduuccttiioonn

Congratulations on purchasing the L4S5MG mainboard. The L4S5MG
mainboard is a Micro ATX mainboard that uses a 4 -layer printed circuit board
and measures 244 mm x 220 mm. The mainboard features a mPGA Socket
478 that accommodates Pentium 4 processors supporting data transfers up to
400 MHz.

The L4S5MG incorporates the XP4G chipset which combines support for the
new high -bandwidth Double Data Rate (DDR) 266/333 SDRAM, Integrated
VGA and the AC 97 audio codec.

Note: SDRAM provides 800 MBps or 1 GBps data transfer depending on whether

the bus is 100 MHz or 133 MHz. Double Data Rate SDRAM (DDR SDRAM)
doubles the rate to 1.6 GBps or 2.7 GBps by transferring data on both the
ris ing and falling edges of the clock. DDR SDRAM uses additional power and
ground lines and requires 184-pin DIMM modules rather than the 168-pin
DIMMs used by SDRAM.

Installing the Processor

Caution: When installing a CPU heatsink and cooling fan make sure that
you DO NOT scratch the mainboard or any of the surface-mount resistors
with the clip of the cooling fan. If the clip of the cooling fan scrapes
across the mainboard, you may cause serious damage to the mainboard
or its components.

On most mainboards, there are small surface-mount resistors near the
processor socket, which may be damaged if the cooling fan is carelessly
installed.

Avoid using cooling fans with sharp edges on the fan casing and the
clips. Also, install the cooling fan in a well-lit work area so that you can
clearly see the mainboard and processor socket.

Before installing the Processor

This mainboard automatically determines the CPU clock frequency and
system bus frequency for the processor. You may be able to change these
settings by making changes to jumpers on the mainboard, or changing the
settings in the system Setup Utility. We strongly recommend that you do not
overclock processors or other components to run faster than their rated speed.

Warning: Overclocking components can adversely affect the reliability of
the system and introduce errors into your system. Overclocking can
pe rmanently damage the mainboard by generating excess heat in
components that are run beyond the rated limits.

This mainboard has a Socket 478 processor socket. When choosing a
processor, consider the performance requirements of the system.
Performance is based on the processor design, the clock speed and system
bus frequency of the processor, and the quantity of internal cache memory
and external cache me mory.
