Processor
 The frequency ratio of some processors may have been locked
by the manufacturer. If you are using this kind of processor,
setting an extended ratio for the processor will have no effect.
The system will instead use its factory default ratio.
 The frequency ratio of processors greater than 8x has been
locked by the manufacturer and will no longer have the flexibility
of using extended ratios. Therefore, the system will use the
processors factory default ratio.
 Selecting an external bus clock other than 66MHz, 100MHz or
133MHz may result to the processors or systems instability and
are not guaranteed to provide better system performance.
System Memory
 DIMMs 1 and 2 both support single-sided and double-sided
DIMMs.
 DIMM 3 supports single-sided and double-sided DIMMs but
double-sided is supported only if DIMM 4 is empty.
 DIMM 4 only supports single-sided DIMM and can be used only
if DIMM 3 is installed with single-sided DIMM too.
5VSB Power
 If you are using the (1) Wake-On-KB/Mouse, (2) Wake-On-LAN
and/or (3) Wake-On-Ring (internal modem) functions, the 5VSB
power source of your power supply must support ≥720mA.
 If you are using the Suspend to RAM function, the 5VSB power
source of your power supply must support ≥1A.
 If you are using the Wake-On-USB Keyboard function, the 5VSB

2.2 System Memory
The system board is equipped with four
168-pin DIMM (Dual In-line Memory
Module) sockets that support unbuffered
PC-133/PC-100 SDRAM DIMM for
133MHz/100MHz system memory bus.
PC SDRAM (Synchronous Dynamic
Random Access Memory) is a fast
memory interface technology that uses
the clock on the chip to synchronize with
the CPU clock so that the timing of the
memory chips and the timing of the
CPU are synchronized. This saves time
during transmission of data, subsequently increasing system
performance.
You can use single-sided or double-sided DIMMs. 16MB, 32MB,
64MB and 128MB are single-sided DIMMs. 32MB, 64MB, 128MB
and 256MB are double-sided DIMMs. The following rules must be
followed when installing DIMM modules.
Warning:
Electrostatic discharge (ESD) can damage your system board,
processor, disk drives, add-in boards, and other components. Perform
the upgrade instruction procedures described at an ESD workstation
only. If such a station is not available, you can provide some ESD
protection by wearing an antistatic wrist strap and attaching it to a
metal part of the system chassis. If a wrist strap is unavailable,
establish and maintain contact with the system chassis throughout
any procedures requiring ESD protection.

 If you use double-sided DIMM, leave DIMM 4 empty.
 If you use single-sided DIMM, only install single-sided DIMM in
DIMM 4.
Only supports single-sided DIMM and can be used only if DIMM 3
is installed with single-sided DIMM too.

Some double-sided DIMMs may come with memory chips mounted
on one side of the module only and are easily mistaken as single-
sided DIMMs. Relevant to the rules on DIMM installation, it is very
important that you know the type of DIMM you are using in DIMM
3 as this will affect the module you are going to use in DIMM 4.The
best way to identify the DIMM is to refer to the boot-up screen.
When you power-on the system, the boot-up screen shows the
systems configuration. Press the <Pause> key to halt scrolling so
that the systems configuration can be read. If it is assumed that
DIMM 3 is installed with single-sided DIMM (with memory chips on
one side of the module only) but the SDRAM at Row(s) field
shows 0 1 2 3 4 5, it means the module is a double-sided DIMM.
If the field shows 0 1 2 3 4, it means the module is actually a
single-sided DIMM.
The System Memory Frequency field in the Advanced Chipset
Features submenu of the BIOS must be set according to the type of
PC SDRAM DIMM used.
The onboard VGA shares 1MB of the system memory. This is fixed
regardless of the size of the system memory. Aside from the 1MB
shared memory, it also uses Dynamic Video Memory Technology
(DVMT). DVMT freely changes in size because graphics memory is
allocated from the system memory according to current needs.

Hardware Installation
2.2.1 Display Cache Using 4MB GPA Card
4MB display cache is supported only when an optional 4MB GPA
(Graphics Performance Accelerator) card is installed in the AGP slot.
The Display Cache Frequency field in the Advanced Chipset
Features submenu of the BIOS must be set according to the
frequency of the GPA card used.
The system board comes with a GPA retention module already
installed onto the AGP slot.The retention module is used to hold the
optional GPA card onto the slot and helps you install the card in the
correct orientation.
Installing the GPA Card
1. Position the GPA card in a 45 degree angle, making sure the
cards Fastening Latch hooks into the retention modules Notch.
