Introduction 1
PowerLeap™Installation Guide
Introduction
Your PowerLeap™ PL-ProMMX CPU upgrade adapter allows Pentium socket 5
and socket 7 systems to take advantage of the latest MMX CPU technology from
Intel, AMD, Cyrix, and IDT.
The CPU upgrade adapter 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 bring 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 K6-2
processor and works with all existing operating systems and x86 applications.

Settings
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.

For systems with an external clock speed of less than 66MHz,
there may be a slight performance sacrifice for your new
CPU. For example, changing to a K6-2/400 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.

Installing the PL-ProMMX
This chapter describes installing your CPU upgrade adapter in your computer.
Figure 1. PL-ProMMX (SVRM)
To compare the performance increase provided by the PL-ProMMX CPU
upgrade adapter, we suggest running the PowerLeap CPU Control Panel®
software 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®.

contains links to files available for downloading, including
the PowerLeap CPU Control Panel®software.

10 Installing the PL-ProMMX
PowerLeap™Installation Guide
$" To install a CPU in the PL-ProMMX upgrade adapter:
1. Loosen the hex nuts at each corner of the provided CPU cooling fan/heatsink.
You should be able to freely move the heatsink up and down.
2. Turn your new CPU over (so that the pins are facing upward) and slide it under
the grooves at the sides of the CPU cooling fan/heatsink.

Figure 2. 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.

4. Turn the assembled CPU cooling fan/heatsink and CPU over and insert the
CPU into the socket on the upgrade adapter, making sure that pin 1 of the
CPU corresponds to pin 1 of the socket. Be sure the CPU is firmly seated in
the socket.

$To install the CPU upgrade adapter in your computer:
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).

PowerLeap™Installation Guide
4. Locate the CPU ZIF socket on the computer’s motherboard. The CPU itself
may be concealed under a CPU cooling fan and/or heatsink.
5. If your computer has a CPU cooling fan/heatsink, remove it.
6. Raise the ZIF socket arm and remove the CPU from the ZIF socket.

sure that pin 1 of the upgrade adapter is installed in pin 1 of the ZIF
socket.

Figure 8. Connecting the power cables
The CPU upgrade adapter must have an independent
(external) power supply in order to operate properly.
For maximum reliability, do not use the unused connector on
the power connector cord to supply power to a CD-ROM
drive or other device. In other words, use the power
connector cord to connect only the upgrade adapter to the
computer’s power supply.
