Installing the CPU Upgrade Board

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.
Ü
To 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.
