Chapter 2 Hardware Setup
To Get Things Ready for Hardware Setup !!!
1. We recommend to install your CPU before any other componentes. For
detailed installation instructions of processor, you can also refer to the
pamphlet enclosed in your CPU package.
2. Installing a cooling fan with a good heatsink is a must for proper heat
dissipation for your CPU. Get ready an appropriate fan with heatsink for
proper installation. Improper fan and installation will damage your CPU.
3. In case CPU Vcore, CPU clock or Frequency Ratio is adjustable onboard,
please follow the instructions described in the User manual for proper
setup. Incorrect setting will cause damage to your CPU.

2-1 Pentium 4 CPU and Installation
2-1.1 To Identify a Pentium 4 CPU
Intel
pentium 4
2.4 GHz / 512 / 533 / 1.5V
(Hyper-threading CPU included)
4) CPU Voltage Vcore
3) System Clock
2) CPU L2 Cache
1) CPU Working Frequency
On the heatsink side of a Pentium 4 CPU, there printed a line of figures to
identify its specifications. The line consists of 4 parts:
1. CPU Working Frequency: this part depicts the working frequency of
the CPU. For example,
2.4 GHz depicts that this CPU is locked to 2.4 GHz working frequency
(18 x 133MHz CPU clock);
2A GHz depicts that this CPU is an A version, locked to 2.0 GHz
working frequency (20 x 100MHz CPU clock)
3.06GHz depicts that this is a 3.06GHz hyper-threading CPU
2. CPU L2 Cache: this part depicts the L2 Cache size. For example,
512 stands for 512 KB L2 Cache; 256 stands for 256 KB L2 Cache
3. System Clock: this part depicts the System Clock (Front Side Bus)
provided by the CPU. For example,
533 stands for a 533MHz system clock provided by a 133MHz CPU
times 4;
400 stands for a 400 system clock provided by a 100 MHz CPU x 4.
4. CPU Voltage Vcore: this part depicts the CPU Voltage. For example,
1.5V stands for a CPU of 1.5V Vcore.
Note: System Clock vs CPU Clock
P4 CPU is a quadpumped CPU. The system bus is provided by the
CPU clock x 4. Therefore, users can figure out the P4 CPU clock by
the System Clock divided by 4.

2-1.2 Pentium 4 CPU Installation with Socket 478
This series is built with CPU Socket
478B (478-pin) supporting the Intel
Pentium 4 CPU:
• Follow the steps described in this
section to install the 478-pin Pentium
4 CPU into the on board Socket 478.
• After installation of Pentium 4 CPU,
you must also install the specific Pen-
tium 4 CPU fan designed in tandem
with this CPU. This CPU Fan instal-
lation is described in next section.
• This series supports Hyper-thread-
ing dual-in-one CPU, the function of
which can be enabled by Windows
XP. (See illustration on the right.)
1. First pull sideways the lever of
Socket 478, and then turn it up
900 so as to raise the upper layer
of the socket from the lower
platform.
2. Configure Pin 1 of CPU to Pin 1
of the Socket, just as the way
shown in the diagram on the right.
Adjust the position of CPU until
you can feel all CPU pins get into
the socket with ease.
3. Make sure that all CPU pins have
completely entered the socket
and then lower down the lever to
lock up CPU to socket.

( If Hyper-threading CPU is
installed successfully with O/S
Win XP, the O/S will enable the
dual-in-one CPU function.)

2-3 Memory Installation
How to tackle the memory modules:
• Make sure to unplug your power supply before adding or removing
memory module. Failure to do so may cause severe damage to both your
mainboard and the memory module.
• Pay attention to the orientation of the DIMM slots. Forcing a DIMM into a
slot improperly will damage the memory module and the slot itself.
• Make sure you have the right type of memory module for your mainboard.
2-3.1 To Install DIMM Module
• This series only supports up to 2GB unbuffered DDR 266/200MHz
SDRAM, with 2 DDR DIMM slots on board. Do not insert other type of
memory module into these slots.
• DDR DIMM slot has 184-pins and one notch. Insert a DDR SDRAM
vertically into the 184-pin slot with the notch-to-rib matching. Press the
module down in a gradual way until it surely reaches the bottom and
clicks straight up the two latches on the left and right of the slot. If any
one of the latches has not turned up completely, you should unplug the
module and press it down the slot a bit more firmly.

2-3.2 To Remove a DIMM:
• Press down the holding latches on both sides of the DIMM slot and the
module will be released from it.

2-4 Install AGP4X with LED & Jumper Safeguard
1. The AGP slot on board supports only AGP 4X card configuration. Users
should install an 1.5V AGP 4X card.
2. A safe installation of AGP 4X card is to set Jp3 to 1-2 closed, resulting in
allowing only 1.5V AGP 4X card to boot system. In this case, if users
cannot boot with an AGP card inserted in the slot, it indicates that the
AGP card is not a correct one. The card should be replaced with a 1.5V
AGP 4X card.
3. LED1 is a Warning LED. Whenever JP3 is set 1-2 closed for an AGP 4X
card installation, and yet the AGP slot is left empty, or the card is not a
correct one, LED1 will light up until a proper installation is done.
Jp3:
AGP4X Safeguard

(default)
Safeguard enabled
1-2 closed for 1.5V AGP 4X only;
(Warning: 3.3V AGP 2X can not boot system)

(Warning: 3.3V AGP card will cause 1.5V
circuitry burn)

2-5 IDE Connector Installation
To install HDD or CD-ROM Drive, you may connect the connector of IDE
cable to the primary (IDE1) or secondary (IDE2) connector on board, and
then connect the gray connector to your slave device and the black
connector to your master device. If you install two hard disks, you must
configure the second drive to Slave mode by setting its jumpers correctly.
Please refer to your hard disk documentation for the jumper settings.
