PowerLeap™Installation Guide

Introduction

Your PowerLeap™ PL-K6-III CPU upgrade kit allows Pentium Socket 7 and

Socket 5 systems to take advantage of the latest CPU technology from AMD. The

PL-K6-III employs patented technology to adapt Socket 7 and Socket 5 systems to

the voltage and pinout requirements of this new generation of processors. It

provides an upgrade solution that would otherwise require the replacement of the

motherboard.

In version 2.0 of the PL-K6-III, we reduced the size of the adapter for easier

installation on a greater number of motherboards. If your motherboard has

capacitors or other components right next to the CPU socket, this new version will

allow installation of the PowerLeap adapter without adding a PGA socket

extender (riser). We also added a DIP switch function that enables/disables the

CPU’s AL-1 pin signal for split-voltage detection. This switch provides an easy

compatibility solution for certain HP Vectra systems and Biostar motherboards

that check the signal.

About the MMXTechnology

Intel’s MMX technology extends the performance of Pentium processors with 57

new instructions, a 32K L1 cache, four new 64-bit data types, and more. For

multimedia and communications applications, MMX can significantly enhance

audio/video playback and image processing. MMX technology is compatible with

a wide range of existing operating systems (including MS-DOS, Windows, OS/2,

and UNIX) and 16/32-bit applications.

PowerLeap™Installation Guide

About the 3DNow!Technology

AMD’s 3DNow! technology is an innovative group of 21 new instructions for the

x86 architecture that brings powerful performance enhancements for multimedia

and floating-point-intensive applications. With 3DNow! technology, applications

can achieve more detailed 3D imaging, faster frame rates for video playback, and

dramatic improvements in audio. 3DNow! technology appears in the AMD K6-III

processor and works with all existing operating systems and x86 applications.

PowerLeap PL-K6-III Special Features

The PowerLeap PL-K6-III offers the following advanced features:

#" Supports the AMD K6-III CPU with 3DNow! and MMX CPU technologies.

#" Provides chip-for-chip replacement, with no software drivers to install.

#" Supports the 66MHz, 75MHz, 83MHz, 95MHz, and 100MHz system bus

(frontside bus).

#" Provides clock multiplier control from 2.5x up to 6.0x--for a maximum CPU

core speed of 400 MHz on a 66MHz FSB motherboard, 450MHz on a

75MHz FSB motherboard, 500MHz on an 83MHz FSB motherboard, and

600MHz on a 100MHz FSB motherboard.

#" Employs PowerLeap’s patented IPS (Independent Power Source)

technology, which provides pure, abundant, and durable power to the

V/Core of split-voltage type CPUs.

#" Provides large 64KB on-chip L1 cache for high-performance

implementation.

#" Supports the AMD K6-III with internal 1:1, 256KB L2 cache.

#" Incorporates PALs to handle the timing of the CPU's on-chip L2 cache

(running at full CPU speed).

Introduction 3

PowerLeap™Installation Guide

#" Includes high-capacity switching VRM (Voltage Regulating Module) circuitry.

#" Provides CPU overcurrent and overvoltage protection (with a self-repairing

fuse).

#" Offers a unique CPU overheating protection function: if the fan fails and the

CPU overheats, the clock frequency is gradually reduced to a level that allows

the system to stay up and running until the situation is corrected.

#" Includes PowerLeap CPU Control Panel software with integrated CPU

cooling technology and support for advanced AMD K6-III performance

enhancements such as Write Allocate.

#" Delivers the most cost-effective MMX CPU upgrade solution!

What You Have

Your PowerLeap™ PL-K6-III CPU upgrade kit includes the following items:

#" The PowerLeap™ PL-K6-III upgrade adapter

#" Power connector cord

#" PowerLeap™ software distribution media (including the CPU Control Panel

software)

#" CPU heatsink and cooling fan (with retaining bracket)

PowerLeap™Installation Guide

Getting Started with the

PowerLeap™ PL-K6-III

This chapter describes how to choose the correct clock multiplier and core voltage

setting for your new AMD K6-III CPU. It also provides a detailed listing of DIP

switch settings for the PowerLeap PL-K6-III.

Quick Start: AMD CPU Settings

This section shows how to use the SW1 DIP switch to choose the correct clock

multiplier and core voltage setting for your new AMD K6-III processor. (For a

detailed description of SW1 DIP switch settings, refer to the next section of this

chapter.)

AMD K6-III CPU SW1 Settings

K6-III 333 (66MHz / 5.0x) ON

12345678910

K6-III 400 (66MHz/6.0x) ON

12345678910

#K6-III 450 (75MHz/6.0x)

12345678910

# For systems with an external clock speed faster than 66MHz.

SW1 Settings: Clock Multiplier, CPU Voltage,

System Compatibility, and CPU Overheating

Protection

This section shows the SW1 clock multiplier and core voltage settings for

supported AMD CPUs. It also lists settings for pin AL-1 compatibility and CPU

overheating protection.

SW1: Pins 1, 2, & 3 (Clock Multiplier)

The default clock multiplier setting for the PL-K6-III is 6x. (For a description of

calculating the bus clock speed, clock multiplier, and CPU speed for a variety of

CPUs, refer to “Technical Reference” later in this document.)

Pins 1, 2, & 3: Clock Multiplier for AMD K6-III

CLKMUL 6x 5.5x 5x 4.5x 4x 3.5x 3x 2.5x

SW1: Pin 1 ON OFF OFF ON ON OFF OFF ON

SW1: Pin 2 OFF OFF ON ON OFF OFF ON ON

SW1: Pin 3 OFF ON ON ON ON OFF OFF OFF

For systems with an external clock speed of less than 66MHz

(50MHz or 60MHz), there may be a slight performance

sacrifice for your new CPU. For example, changing to a

K6-III 400 from a Pentium-75 will result in a system upgrade

speed of 300MHz (not 400MHz). In this case, you can get

improved performance by adjusting the external clock speed

to 66MHz.
