Overview

Intel Celeron processors, the plastic pin grid array
(P.P.G.A.) 370

The Intel Celeron processors provide power to handle the internet, educational
programs, interactive 3D games, and productivity applications. The Intel Celeron
processors at 466, 433, 400, 366, 333 and 300A MHz include integrated L2 cache
128Kbyte. The core for the 466, 433, 400, 366, 333 and 300A MHz processors
have 19M transistors due to the addition of the integrated L2 cache 128Kbyte. All
the Intel Celeron processors are available in the plastic pin grid array (P.P.G.A.)
form factor. The P.P.G.A. form factor is compatible with the 370 pin socket. All
the Intel Celeron processors are available in the plastic pin grid array (PPGA)
package. The PPGA package is compatible with the 370 pin socket and provides
more flexibility to design low cost systems by enabling lower profile and smaller
systems and providing the potential for reducing costs of processor retention and
cooling solutions. Like the Intel Celeron processors that utilize S.E.P.P., the Intel
Celeron processors that use P.P.G.A., feature a P6-microarchitecture-based core
processor on a single-sided substrate without BSRAM componentry.

The Intel Celeron processor at 466, 433, 400, 366, 333, and 300A MHz. Includes
Intel MMX[tm] media enhancement technology. Offers Dynamic Execution
technology.
Includes a 32Kbyte (16Kbyte/16Kbyte) non-blocking, level-one cache that provides
fast access to heavily used data. Intel Celeron processors at 466, 433, 400, 366,
333 and 300A MHz include integrated L2 cache 128Kbyte. All the Intel Celeron
processor utilize the Intel P6 microarchitecture’s multi-transaction system bus at
66MHz. The 466, 433, 400, 366, 333 and 300A MHz processors utilize the Intel
P6 microarchitecture’s multi-transaction system bus with the addition of the L2
cache interface. The combination of the L2 cache bus and the processor-to-main­memory system bus increases bandwidth and performance over single-bus

processors.
Intel MMX technology includes new instructions and data types that allow

IntroductionEP-3WXM/2/4

Page 1-3

applications to achieve a new level of performance. Intel’s MMX technology is
designed as a set of basic, general-purpose integer instructions that are easily
applied to the needs of a wide diversity of multimedia and communications
applications. The highlights of the technology are:

* Single Instruction, Multiple Data (SIMD) technique
* 57 new instructions
* Eight 64-bit wide MMX technology registers
* Four new data types

Installation and Removal

Installation:

Install the processor and the fan heatsink using the Installation Notes provided
with the boxed processor. First, raise the handle of the 370-pin socket. Carefully
install the processor into the 370-pin socket making sure that none of the pins are
bent. Then close the handle of the socket. Next install the fan heatsink. Make sure
to install the heatsink onto the processor after the processor has been inserted
into the 370-pin socket. Place the fan heatsink onto the processor such that the
integrated clip lines up with the socket’s attach tabs. This will align the fan cable
with the PGA370 mark on the 370-pin
socket. Remember not to damage the
thermal interface pad. Attach the clip onto
the socket’s attach tabs. (A small tool, such
as a pen, may make this process easier.) Take
care to consider potential scraping of the
motherboard underneath the 370-pin socket
attach tabs. Connect the attached fan power
cable to the motherboard connector and
quickly power on the system to verify that
the processor fan is running.

Introduction EP-3WXM/2/4

Page 1-4

Removal:

To simplify the following process, consider removing the motherboard from the
chassis before removing the processor. First, unplug the fan power cable from the
motherboard’s connector. Then pull the integrated clip away from the socket’s tab
nearest the fan cable. (A small tool, such as a pen or screwdriver, may make this
process easier.) Once the clip is free, slowly lift the fan heatsink straight up away
from the socket and the processor. (If the processor has been in operation for a
long period of time, then this step may require some extra force; this is because the
heat dissipated from the processor will have affected the thermal interface pad)
Next, lift up the handle of the 370-pin socket. Finally, carefully remove the proces­sor from the socket making sure not to bend any of the processor pins.

Intel(R) 810 chipset features

The Intel(R) 810 chipset that Built on the strong foundation of Intel(R) 440BX
AGPset technology, the Intel(R) 810 chipset has re-engineered the Value PC,
providing next generation features and great graphics performance.

The 82810 Graphics Memory Controller Hub (GMCH) features : Intel(R)
graphics technology and software drivers, using Direct AGP (integrated AGP) to
create vivid 2D and 3D effects and images. The 82810 chip feature integrated
Hardware Motion Compensation to improve soft DVD video quality.

The Inte(R) 82810 chipset use Intel(R) Dynamic Video Memory Technology (D.
V.M.T.) is an architecture that offers breakthrough performance for the
(motherboard) PC through efficient memory utilization and Direct AGP. The
system OS uses the Intel software drivers and intelligent memory arbiter to
support richer graphics applications.

The 82801 I/O Controller Hub (ICH) employs the Intel(R) Accelerated Hub
Architecture to make a direct connection from the graphics and memory to the
integrated AC97 controller, the IDE controllers (ATA/66 or ATA/33), dual USB
ports, and PCI add-in cards.

IntroductionEP-3WXM/2/4

Page 1-5

The Accelerated Hub Architecture provides twice the bandwidth of the PCI bus at
266 MB per second. This allows a wider flow of rich information from the I/O
controller to the memory controller, with optimized arbitration rules allowing
more functions to run concurrently, enabling more life-like audio and video.

The Integrated Audio-Codec 97 controller enables software audio and modem
(AMR Riser Optional) by using the processor to run sound and modem software.
By reusing existing system resources, this feature adds flexibility, improves
sound and modem quality.

The 82802 Firmware Hub (FWH, 4MB) stores system BIOS and video BIOS,
eliminating a redundant nonvolatile memory component. In addition, the 82802
contains a hardware Random Number Generator (RNG). The Intel(R) RNG
provides truly random numbers to enable fundamental security building blocks
supporting stronger encryption, digital signing, and security protocols for the
future application program.

EP-3WXM/2/4 Form-Factor

The EP-3WXM/2/4 is designed with Micro-ATX form factor - the new industry
standard of chassis. The Micro-ATX form factor is essentially a Baby-AT base­board rotated 90 degrees within the chassis enclosure and a new mounting
configuration for the power supply. With these changes the processor is relocated
away from the expansion slots, allowing them all to hold full length add-in cards.
Micro-ATX defines a double height aperture to the rear of the chassis which can
be used to host a wide range of onboard I/O. Only the size and position of this
aperture is defined, allowing PC manufacturers to add new I/O features (e.g.; TV
input, TV output, modem, LAN, etc.) to systems. This will help systems integra­tors differentiate their products in the marketplace, and better meet your needs.

• Smaller size promotes a smaller system size.

• I/O shield does not need to be retooled in an ATX 2.01 or later. Mainboard
could be used in an ATX 2.01-compliant.

• A smaller power supply cam be used. High integration on mainboard reduces
the system costs.

I/O Shield Connector

The EP-3WXM/2/4 is equipped with an I/O back panel. Please use the appropri-
ate I/O shield (figure 3).

Power-On/Off (Remote)

The EP-3WXM/2/4 has a single 20-pin connector for ATX power supplies. For
ATX power supplies that support the Remote On/Off feature, this should be con­nected to the systems front panel for system Power On/Off button. The systems
power On/Off button should be a momentary button that is normally open.

The EP-3WXM/2/4 has been designed with “Soft Off" functions. You can turn Off
the system from one of two sources: The first is the front panel Power On/Off the
button, and the other is the "Soft Off" function (coming from the EP-3WXM/2/4’s
onboard circuit controller) that can be controlled by the operating system. Win­dows 95/98 will control this when the user clicks that they are ready to Shutdown
the system.
