Intel Pentium 4 Processor Family
Cooling Solutions
As processor technology pushes to faster speeds and higher performance, thermal management
becomes increasingly crucial when building computer systems. Maintaining the proper thermal
environment is key to reliable, long-term system operation. The overall goal in providing the proper
thermal environment is keeping the processor below its specified maximum case temperature.
Heatsinks induce improved processor heat dissipation through increased surface area and
concentrated airflow from attached fans. In addition, interface materials allow effective transfers of
heat from the processor to the heatsink. For optimum heat transfer, Intel recommends the use of
thermal grease and mounting clips to attach the heatsink to the processor.
When selecting a thermal solution for your system, please refer to the website below for collection of
heatsinks evaluated and recommended by Intel for use with Intel processors. Note, those heatsinks are
recommended for maintaining the specified Maximum T case requirement. In addition, this collection
is not intended to be a comprehensive listing of all heatsinks that support Intel processors.

Chapter 1
Introduction
The special designed 2-user motherboard allows (848PTWIN) two users to share the
computing power of a single PC system. With integrated connectivity hardware onboard, the
motherboard comes with innovative software, the MagicTwin®, allowing 2 users to be
connected to it and runs up to two stations directly from it simultaneously. The unique and
copyright-protected MagicTwin® technology makes each of the 2 users feel like having
himself his own Windows-XP computer. Each user needs to have himself his own keyboard,
mouse, sound device, and monitor. All remaining PC hardware are shared, even the IP.
Both users can operate on their own station concurrently just like the operation of a standard
PC. There is no obvious delay because of the Time-slicing/Multiplexing technology built-in.
Each user gets an exact and extremely short defined moment to access to the PC system,
devices, applications and Windows itself. Resources are only claimed for nanoseconds at a
time, usually from electronic memory, or cache. Both users get from Windows and the PC,
what they really need when they need it! The MagicTwin solution turns the single PC into a
cost-effective multi-user system.
The setup is intuitive and easy. In only a few minutes, users can install and start using their
new workstation. No network administrator is needed as everything to network the
workstations together is done automatically with the MagicTwin software. You can add
immediately additional user station to the single system and turn one PC into two.

2-3-2 About Intel Pentium 4 478-pin CPU
9
This motherboard provides a 478-pin surface mount, Zero Insertion Force (ZIF) socket,
referred to as the mPGA478B socket supports Intel Pentium 4 processor in the 478 Pin
package utilizes Flip-Chip Pin Grid Array (FC-PGA2) package technology.
The CPU that comes with the motherboard should have a cooling FAN attached to prevent
overheating. If this is not the case, then purchase a correct cooling FAN before you turn on
your system.
WARNING!
Be sure that there is sufficient air circulation across the processor’s heatsink and
CPU cooling FAN is working correctly, otherwise it may cause the processor and
motherboard overheat and damage, you may install an auxiliary cooling FAN, if
necessary.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF socket and
open it by first pulling the level sideways away from the socket then upward to a 90-degree
angle. Insert the CPU with the correct orientation as shown below. The notched corner
should point toward the end of the level. Because the CPU has a corner pin for two of the
four corners, the CPU will only fit in the orientation as shown.
CPU ZIF mPGAB Socket
Colden Arrow
mPGA478B
When you put the CPU into the ZIF socket. No force require to insert of the CPU, then press
the level to Locate position slightly without any extra force.
2-4 Install Memory
This motherboard provides two 184-pin DUAL INLINE MEMORY MODULES (DIMM)
sites for memory expansion available from minimum memory size of 64MB to maximum
memory size of 2.0GB DDR SDRAM.

Generally, installing DDR SDRAM modules to your motherboard is very easy, you can refer
to figure 2-4 to see what a 184-Pin DDR266/DDR333/DDR400 DDR SDRAM module looks
like.
DIMM2 (BANK2 + BANK3)
DIMM1 (BANK0 + BANK1)
NOTE!
When you install DIMM module fully into the DIMM socket the eject tab should be
locked into the DIMM module very firmly and fit into its indention on both sides.
WARNING!
For the DDR SDRAM CLOCK is set at 200MHz, use only DDR400-compliant DDR
Modules. When this motherboard operate at 200Mhz, most system will not even
boot if non-compliant modules are used because of the strict timing issues, if your
SDR Modules are not DDR400-compliant, set the DDR SDRAM clock to 133MHz
to ensure system stability.
2-5 Expansion Cards
WARNING!
Turn off your power when adding or removing expansion cards or other system
components. Failure to do so may cause severe damage to both your motherboard
and expansion cards.
2-5-1 Procedure For Expansion Card Installation
1. Read the documentation for your expansion card and make any necessary hardware or
software setting for your expansion card such as jumpers.
2. Remove your computer’s cover and the bracket plate on the slot you intend to use.
3. Align the card’s connectors and press firmly.
4. Secure the card on the slot with the screen you remove above.
5. Replace the computer system’s cover.
6. Set up the BIOS if necessary.
7. Install the necessary software driver for your expansion card.
2-5-2 Assigning IRQs For Expansion Card
Figure 2-4
11
Some expansion cards need an IRQ to operate. Generally, an IRQ must exclusively assign to
one use. In a standard design, there are 16 IRQs available but most of them are already in use.
Standard Interrupt Assignments

IMPORTANT!
If using PCI cards on shared slots, make sure that the drivers support “Shared
IRQ” or that the cards don’t need IRQ assign ments. C o nfli c ts will arise between
the two PCI groups that will make the system unstable or cards inoperable.
2-5-4 AGP Slot
This motherboard provides an AGP Slot, only support the 1.5V 4X/0.8V 8X AGP VGA card.
12
Do not use AGP 2X card (3.3V) in this motherboard. It will burn and damage the
motherboard due to Intel® 848 chipset can not support AGP 2X (3.3V).
IMPORTANT!
Before you plug-in AGP card, please make sure the following notice is
fully understood and practiced. If your AGP card has “AGP 4X notch
(show below) please make sure your AGP card is AGP 4X/8X
(1.5V/0.8V) not AGP 2X (3.3V)

SiS 305 & ATi Rage 128 Pro AGP card those golden finger is compatible
with 2X/4X mode AGP slot, but only can support 2X (3.3V) only. If you
install these cards in Intel® 848 based motherboard it will burn and damage
the motherboard.
Example 2:
We also find Diamond Vipper V770 golden finger is design for 2X/4X mode
AGP Slot. It can be adjusted the jumper for AGP 2X (3.3V) or AGP 4X
(1.5V). But the factory default setting is 2X (3.3V). If you install this AGP
card in motherboard without change the jumper setting to 4X (1.5V), it will
burn the motherboard.
