Introduction
Your PowerLeap™ PL-K6-III/98 CPU upgrade board allows Pentium Socket 5
and Socket 7 systems to take advantage of the latest 3DNOW! & MMX CPU
technology from AMD, Intel, Cyrix, and IDT.
The CPU upgrade board employs patented technology to adapt Socket 5 and Socket
7 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.
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.
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
& K6-2 processor and works with all existing operating systems and x86
applications.

This section shows the SW1 clock multiplier and voltage settings for Intel, AMD,
Cyrix/IBM, and IDT CPUs. To reduce power consumption, dual-voltage CPUs
use two separate supply voltages: an I/O interface voltage and a lower core voltage
for the processor.

* Note the actual voltage printed on the CPU label.
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
K6-166 from a Pentium-75 will result in a system upgrade
speed of 150MHz (not 166MHz). In this case, you can get
improved performance by adjusting the external clock speed
to 66MHz.

PowerLeap™Installation Guide
SW1: Pin 10 (CPU Overheating Protection)
The CPU upgrade board offers a unique CPU overheating protection function that can
prevent damage to your CPU if the temperature increases. When this function is
enabled, the CPU speed will automatically drop 60% if the CPU temperature
reaches 70°C or higher. This prevents the CPU from overheating.

PowerLeap™Installation Guide
Installing the CPU Upgrade Board
This chapter describes installing your CPU upgrade board.
Before Installation
Prior to starting installation, take your CPU upgrade board from its packing and
remove the protective foam pad, taking care not to damage the pins. If the package
includes a CPU cooling fan & heatsink, remove it too.
Figure 1. The PL-K6-III/98

12 Installing the CPU Upgrade Board
PowerLeap™Installation Guide
To compare the performance increase provided by the PL-K6-III/98 CPU
upgrade board, we suggest running the PowerLeap CPU Control Panel®both
before and after installation. If you are uncertain about the speed of your existing
CPU, you can determine the speed by running the PowerLeap CPU Control
Panel®.
Installation
If your package came with a CPU cooling fan & heatsink, install the CPU upgrade
board as follows.
$To install the CPU upgrade board:
1. Place your computer where you will have plenty of space to work.
2. Turn the computer off and disconnect all power cords and cables from
the rear of the computer.
3. Remove the cover from the computer (as described in the computer
documentation).
4. Locate your existing CPU on the computer’s motherboard. The CPU will be
clearly labeled with the manufacturer’s name (such as “Intel”), and markings
identifying the CPU model and speed (such as Pentium-75).
5. Remove the existing CPU cooling fan.

Installing the CPU Upgrade Board 13
PowerLeap™Installation Guide
6. Remove the existing CPU from the ZIF socket.
Figure 2. Removing the existing CPU and CPU cooling fan
7. Hold the provided CPU cooling fan & heatsink so that the CPU plate faces
upward.
8. Loosen the hex nuts at each corner of the CPU cooling fan. You should be able
to freely move the CPU plate up and down.

Figure 3. Sliding the CPU onto the CPU plate
Pin 1 of the CPU must occupy the corner diagonally opposite
the fan’s power cable. If necessary, remove the CPU from the
CPU plate and insert it again, with pin 1 in the correct
position.

11. Turn the CPU cooling fan & heatsink over and insert the CPU into the upgrade
board, making sure that pin 1 of the CPU corresponds to pin 1 of the
upgrade board. Be sure the CPU is firmly seated in the board.
