Thermal 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.

2-3-1 Glossary

Chipset (core logic) - two or more integrated circuits which control the interfaces between the system processor, RAM, I/O devises, and adapter cards.

Processor socket - the 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 interface for video cards, sound cards, network interface cards, and modems; runs at 33MHz.

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.

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 Pentium III CPU has

256K or above, while Celeron CPU will have 128K.

The way to recognize the specification of CPU from the packing Pentium III 370 pins FC-PGA

On the surface of the CPU as shown on the right picture, under the word of “PENTIUM III” the code is:

RB 80526 P2 866 256 RB :

FC–PGA packing

P2 :

P2–133MHz front side bus frequency

PY–100MHz front side bus frequency

866 :

CPU internal frequency, where here is

866MHz

256 :

the size of L2 cache, where here is 256K

Celeron FC–PGA

On the surface of the CPU as shown on the right picture, under the word of “Celeron” the code is:

566/128/66/1.5V 566 :

CPU internal frequency, where here is 566MHz

128 :

the size of L2 cache, where here is 128K

66 :

front side bus frequency, where here is 66MHz

1.5V :

the voltage for the CPU

2-3-2 Setting CPU Bus Clock & Memory Clock Jumper

Setting the front side bus frequency and SDRAM frequency

The motherboard uses jumper JS1, JS2, JS3 and JS4 for the front side bus frequency and SDRAM frequency setting as shown from the table below:

CPU/SDRAM (MHz) JS1 JS2 JS3 JS4

AUTO ON ON 1-2 1-2

66/100

(Default)

OFF OFF 2-3 2-3 100/100 OFF OFF 2-3 1-2 133/100 OFF OFF 1-2 1-2 133/133 OFF OFF 1-2 2-3

Example: Using a Pentium III 866 CPU with front side bus frequency of 133MHz and

PC-133 SDRAM module, the setting of JS3 will be 1-2 and JS4 will be 2-3. This sets both CPU BUS CLOCK and SDRAM CLOCK to be 133MHz.

For experience user looking for over clocking possibility, please refer to sec 2-3-4.

2-3-3 Install CPU

This motherboard provides a ZIF socket 370. 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.
