Introduction
Your PowerLeap™ PL-ProMMX Plus CPU upgrade board 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 board employs patent pending technology to adapt socket 5 and
socket 7 systems to the voltage and pinout requirements of this new generation of
processors. By providing an upgrade solution that would otherwise require the
replacement of the motherboard, PowerLeap™ lets you enjoy the most cost-
effective MMX CPU upgrade solution.
About 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 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.

PowerLeap™Installation Guide
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.
JP2 Settings: CPU Voltage and CPU Overheating
Protection
This section shows the CPU core voltage settings for Intel, AMD, Cyrix/IBM,
and IDT CPUs. It also discusses enabling and disabling the CPU overheating
protection function.
Pins 1-10: CPU Core Voltage
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.

The CPU upgrade board offers a unique CPU overheating protection function—
when enabled, the CPU speed will automatically drop 50% if the CPU
temperature reaches 70°C. This prevents the CPU from overheating.

PowerLeap™Installation Guide
Installing the CPU Upgrade Board
This chapter describes installing your PowerLeap™ PL-ProMMX Plus 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. PowerLeap™ PL-ProMMX Plus (SVRM)

12 Installing the CPU Upgrade Board
PowerLeap™Installation Guide
To compare the performance increase provided by the PowerLeap™ PL-
ProMMX Plus CPU upgrade board, we suggest running the Landmark System
Speed Test both before and after installation. If you are uncertain about the
speed of your existing CPU, you can determine the speed by running the
Landmark System Speed Test. For details, see “Running the Landmark System
Speed Test” later in this guide.
Installation
If your package came with a CPU cooling fan & heatsink, install the CPU
upgrade board as follows.
ÜTo install the CPU upgrade board:
Place your computer where you will have plenty of space to work.
Turn the computer off and disconnect all power cords and cables from
the rear of the computer.
Remove the cover from the computer (as described in the computer
documentation).
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).
Remove the existing CPU cooling fan.
Remove the existing CPU from the ZIF socket.

Installing the CPU Upgrade Board 13
PowerLeap™Installation Guide
Figure 2. Removing the existing CPU and CPU cooling fan
Hold the provided CPU cooling fan & heatsink so that the CPU plate faces
upward.
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.

14 Installing the CPU Upgrade Board
PowerLeap™Installation Guide
Turn your new CPU over (so that the pins are facing upward) and slide it
under the grooves at the sides of the CPU plate.

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.

Installing the CPU Upgrade Board 15
PowerLeap™Installation Guide
Tighten the hex nuts. The CPU should be firmly attached to the CPU plate.
Figure 4. Tightening the hex nuts

16 Installing the CPU Upgrade Board
PowerLeap™Installation Guide
Make sure that the upgrade board’s JP1 and JP2 jumper settings are correct
(refer to the previous chapter). These jumper switches let you set the correct
external clock frequency, clock multiplier, and voltage for the upgrade board.
