This page contains a summary of the important notes that must be
given special attention to prior to using the system board.

Over Voltage

The Over Voltage function allows you to manually adjust to a higher
core voltage that is supplied to the CPU. Although this function is
supported, we do not recommend that you use a higher voltage
because unstable current may be supplied to the system board
causing damage.

CPU Overclocking

The CPU Overclocking function allows you to adjust the processors
bus clock by 1MHz stepping. However, overclocking may result to
the processors or systems instability and are not guaranteed to
provide better system performance.

GPA

The system board supports 4MB display cache. To use this function,
you must install a 4MB GPA (Graphics Performance Accelerator)
card into the AGP slot. The GPA card is optional.

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.

 If you want to manually select the CPUs FSB (using JP9 and

JP10) instead of using its default setting which is Auto, make sure
the Open Slight Adjust field in the CPU Frequency Control
submenu of the BIOS is set to Disabled.

2.2 System Memory

The system board is equipped with
three 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.

Refer to System Memory Frequency in the Advanced Chipset
Features section in chapter 3 for more information.

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. Refer
to chapter 1 for the type of memory supported by the system
board.

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.
