Chapter 2 Hardware Setup
1. We recommend to install your CPU before any other components.
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 heat sink is a must for proper
heat dissipation for your CPU. Get ready an appropriate fan with
heat sink for proper installation. Improper fan and installation will
damage your CPU.
3. In case CPU Vcore, CPU clock or Frequency Ratio is adjustable on
board, please follow the instructions described in the User’s manual
for proper setup. Incorrect setting will cause damage to your CPU.
The following topics are included in this chapter:

Chapter 2 Hardware Setup
2-1 CPU Installation with Socket 478B
2-1.1 To Identify a Pentium 4 CPU
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. The Intel P4 processor with three differeent System Bus
mode provides a variety of speeds ranging from 2A Ghz to 3.2Ghz.
400MHz System Bus: 2.60, 2.50, 2.40, 2.20, 2A GHz
533MHz System Bus: 3.06, 2.80, 2.66, 2.53, 2.40, 2.26 GHz
800MHz System Bus: 3.20, 3, 2.80C, 2.60C, 2.40C GHz
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 Bus: this part depicts the System Bus (Front Side Bus) is
provided by CPU clock x 4. For example,
800MHz = 200MHz(CPU clock) x 4; 533MHz = 133MHz x 4
400MHz = 100MHz x 4
Note: System Bus vs CPU Clock
P4 CPU is a quad-pumped CPU. The system bus is provided by the
CPU clock x 4. Therefore, users can figure out the P4 CPU clock by the
System Bus divided by 4.
(Hyper-Threading CPU included)

3) System Bus
Pentium 4 with Hyper Threading Technology :
The new P4 processors at 2.40C, 2.60C, 2.80C, 3, 3.20GHz with an
advanced 800MHz system bus and P4 processor at 3.06Ghz with
533MHz system bus all support Hyper Threading Technology.

2-1.2 CPU Installation with Socket 478B
This mainboard 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 Pen-
tium 4 CPU into the on board
Socket 478.
• After installation of Pentium 4 CPU,
you must also install the specific
Pentium 4 CPU fan designed in
tandem with this CPU. This CPU
Fan installation is described in next
section.
• This mainboard supports Hyper-
threading 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
900so as to raise the upper layer
of the socket from the lower
platform.
3. Make sure that all CPU pins have
completely entered the socket
and then lower down the lever
to lock up CPU to socket.
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.

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

How to tackle the memory Modules:
• Make sure to unplug your power supply before adding or removing
memory module.
• Pay attention to the orientation of the DIMM 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.
• To enable Dual-channel memory function, users should insert totally
identical (size and frequency) DDR module pair into the bank-pair. In
this series, DIMM1 and DIMM3 is a pair, and DIMM2 and DIMM4 is
another.

23
Chapter 2 Hardware Setup
2-3.3 To Remove a DIMM
Power off the system first, and then press down the holding latches on
both sides of slot to release the module from the DIMM slot.
• Dual Channel memory configuration provides higher performance than
Single Channel configurations
• Matched DIMMs need to have identical density, DRAM technology,
DRAM bus width, and equal number of memory banks.
• This series supports up to 4GB unbuffered Dual-channel DDR 400/
333/266 SDRAM, with 4 DDR DIMM slots on board. Do not insert
other type of modules into these slots.
• The dual memory controller can double the DDR memory bandwidth
up to 6.4GB/s with DDR400, 5.4GB/s with DDR333 and 4.2GB/s with
DDR266.
