HARDWARE INSTALLATION

2-1.2 CPU Type Setting

This mainboard supports jumperless CPU type setting, no jumper or switch is
needed. Select your Intel Pentium II / Pentium III CPU under “CHIPSET
FEATURES SETUP” in BIOS(CMOS) Setup Menu.

The Intel Pentium CPU currently available in the market are listed as below:

CPU Type CPU Clock Ratio CPU Clock Frequency

Intel Pentium II 233 3.5x 66MHz
Intel Pentium II 266 4x 66MHz
Intel Pentium II 300
Intel Pentium II 333
Intel Pentium II 350
Intel Pentium II 400
Intel Pentium II 450
Intel Pentium III 450 4.5x 100MHz
Intel Pentium III 500 5x 100MHz

This mainboard also supports CPU over-clocking by adjusting the CPU Clock
Frequency and CPU Clock Ratio under BIOS Setup.

Warning: Normally, Intel Pentium II CPU supports 66/100MHz, the other CPU
Clock Frequency 75.0/83.3/103/112/124/133MHz are available only for
internal test or end-user over-clocking testing, which may cause your system
unstable or serious damage.

HARDWARE INSTALLATION

2-1.3 Power On Mode (Optional)

JP3 Power On Mode

The mainboard supports two kinds of system power on mode, panel switch
power on (PAN SW. PWR ON) mode and keyboard power on (KB PWR ON)
mode. Set JP3 at pin 1-2 to use power switch/button to power on your system.

If you want to use the “Keyboard Power On” function, make sure you have a
300mA/+5VSB or above ATX power supply and the supporting mainboard
BIOS. Set JP3 at pin 2-3 to enable the keyboard power on mode.

The mainboard supports AGP Overspeed Mode. Set JP3 at pin 2-3, ASYN.
AGP (Overspeed Mode), for better AGP performance if your system is

running overclocking. Set JP3 at pin 1-2 for default AGP operation.
Note: The maximum clock of the AGP specification is 66MHz. If the system

bus clock is larger than 66MHz, you can set this jumper to pin 2-3 to force
AGP clock synchronize with bus clock. However, doing so may probably cause
your system unstable or serious damage

Attach the ATX power button or suspend switch cable to this connector.
In the ATX power system, this connector will be not only an ATX power

button, but a suspend switch as well. Details are describes as below:
When the system is off, push the power button to turn the system on. When

the system is on, push the power button rapidly within 4 seconds to switch the
system to the suspend mode, and, by pushing and holding the button for
more than 4 seconds, it will turn the system completely off. When the system
is in the suspend mode, push the power button rapidly to turn the system on.

When the system is in suspend mode, the GRN LED will flash. And when the
system is in normal working mode, the GRN LED will not work.

HARDWARE INSTALLATION

2-3 System Memory Installation

There are 3 pcs 168-pin DIMM (Dual Inline Memory Module) sockets on the
mainboard which support Synchronous DRAM and Registered SDRAM, and
allow you install system memory maximum up to 768MB.

DIMM Sockets

2-3.1 Type

This mainboard supports Synchronous DRAM and Registered SDRAM.
However, mixing SDRAM and Registered SDRAM is not allowed. Install one
type only in your system for better compatibility.

2-3.2 Speed

The memory speed normally marked as: -15, -12, -10, -7, -8, PC-100.
The meaning is,

-15 = 15ns, and the maximum clock is 66MHz

-12 = 12ns, and the maximum clock is 83MHz

-10 = 10ns, and the maximum clock is 100MHz

-8 = 7ns, and the maximum clock is 125MHz

-7 = 8ns, and the maximum clock is 142MHz
PC-100 = New Intel specification for high memory speed

24

HARDWARE INSTALLATION

With 100MHz or above CPU Bus Clock.

This motherboard supports all the above memory speed. For better system
performance and reliability, we suggest that you use PC-100 SDRAM if
100MHz or above CPU Bus Clock is used in your system.

2-3.3 Buffered and Non-buffered

Only the non-buffered DIMM can be used in this mainboard.

The difference between buffered and non-buffered DIMM can be identified by
the notch position shown above.

2-3.4 2-clock and 4-clock signal

Both 2-clock and 4-clock SDRAM DIMM supported by this mainboard.

2-3.5 Parity and Non-parity

This mainboard supports standard 64 bit (Non-parity) and 72 bit (Parity)
DIMM modules.

25

HARDWARE INSTALLATION

2-3.6 Memory Auto detection by BIOS

This mainboard BIOS can automatically detect the DIMM memory size and
type, so you do not need to adjust any hardware or software settings. The
maximum memory size supported up to 768MB.

2-3.7 Suggested SDRAM combination

This mainboard supports the following SDRAM combination.

DIMM Location

DIMM 1 SDRAM 8, 16, 32, 64 128, 256MB 256MB
DIMM 2 SDRAM 8, 16, 32, 64 128, 256MB 256MB
