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. For vendor list of heatsink and fan, please visit :

Chipset (or core logic) - two or more integrated circuits which control the interfaces between the system processor, RAM, I/O devises, and adapter cards. Processor slot/socket - the slot or socket used to mount the system processor on the motherboard.

Slot (AGP, PCI, ISA, RAM) - the slots used to mount adapter cards and system RAM. AGP - Accelerated Graphics Port - a high speed interface for video cards; runs at 1X

(66MHz), 2X (133MHz), or 4X (266MHz). PCI - Peripheral Component Interconnect - a high speed in terface for video cards, sound cards, network interface cards, and modems; runs at 33MHz. ISA - Industry Standard Architecture - a relatively low speed interface primarily used for sound cards and modems; runs at approx. 8MHz.

Serial Port - a low speed interface typically used for mouse and external modems. Parallel Port - a low speed interface typically used for printers. PS/2 - a low speed interface used for mouse and keyboards. USB - Universal Serial Bus - a medium speed interface typically used for mouse, keyboards,

scanners, and some digital cameras.

Sound (interface) - the interface between the sound card or integrated sound connectors and

speakers, MIC, game controllers, and MIDI sound devices.

LAN (interface) - Local Area Network - the interface to your local area network. BIOS (Basic Input/Output System) - the program logic used to boot up a computer and

establish the relationship between the various components. Driver - software, which defines the characteristics of a device for use by another device or other software. Processor - the "central processing unit" (CPU); the principal integrated circuit used for doing the "computing" in "personal computer" Front Side Bus Frequency - the working frequency of the motherboard, which is generated by the clock generator for CPU, DRAM and PCI BUS. CPU L2 Cache - the flash memory inside the CPU, normally Athlon CPU has 256K or above, while Duron will have 64K.

2-3-2 About Intel Pentium 4 478-pin CPU

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 90degree 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.

DDR1 (BANK0+BANK1)

Figure 2-4

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 133MHz, use only DDR266compliant DDR Modules. When this motherboard operate at 133Mhz, most system will not even boot if non-compliant modules are used because of the strict timing issues, if your DDR Modules are not DDR266compliant, set the DDR SDRAM clock to 100MHz 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

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

IRQ Priority Standard function

0 N/A System Timer 1 N/A Keyboard Controller 2 N/A Programmable Interrupt 3 * 8 Communications Port (COM2) 4 * 9 Communications Port (COM1) 5 * 6 Sound Card (sometimes LPT2) 6 * 11 Floppy Disk Controller 7 * 7 Printer Port (LPT1) 8 N/A System CMOS/Real Time Clock
