PowerLeap™ Installation Guide
Introduction
Your PowerLeap™ PL/586-133 is a clock- tripled/quadrupled processor upgrade for
80486SX/SX2, 80486DX/DX2, and 80486DX4 computers. The PowerLeap™
processor upgrade uses the AMD X5-133 CPU (Am5x86-P75 CPU). PowerLeap™
installs directly into your computer’s existing CPU socket or, if you cannot remove the
original CPU, into an Intel Overdrive or 80487SX socket. Please contact your dealer for
more information about the CPU.
Before installing the PowerLeap™ processor upgrade, we
recommend setting your motherboard’s onboard clock frequency to
33MHz for the BEST Performance. For more information, refer to
your motherboard’s documentation or contact your system vendor.
