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.
- Page 6 “Setting the JP1 Jumper Switch” later in this manual. You must use the JP1 jumper switch on the PowerLeap™ upgrade to select the 3.3V/3.45V CPU voltage setting. For more information, please see the section “Setting the JP1 Jumper Switch” later in this manual.
- Page 7 If any of these items is missing or damaged, contact the dealer from whom you purchased PowerLeap™. Save the packing materials for future use. Leave the PowerLeap™ processor upgrade in its original packing until you are ready to install it.

Page 18: Figure 7. The Powerleap™ Pl/586-133 Sw1 Dip Switch
Before installing the processor upgrade, you must set the SW1 DIP switch on the PowerLeap™. You can find SW1 on the top of the Power Leap™ PL/586-133. The SW1 DIP switch is shown in the following figure and described below. - Page 19 Installing PowerLeap™ PL/586-133 SW1 Position 1: CPU Socket Type Selection The PowerLeap™ offers several installation options to match your computer’s CPU configuration. Before installing the processor upgrade, you must specify the selected socket type by setting position 1 of the SW1 DIP switch. This position is set to OFF by default.

Page 22: Figure 8. Orienting And Inserting The Processor Upgrade (Standard And Zif Sockets)
Installing PowerLeap™ PL/586-133 Orienting & Inserting PowerLeap™ Before starting installation, locate pin 1 on the PowerLeap™ processor upgrade and the pin 1 hole on the motherboard CPU socket (see the figure below). When you install the processor upgrade, pin 1 of the processor upgrade must be installed in the pin 1 hole of the motherboard CPU socket. - Page 23 Installing PowerLeap™ PL/586-133 Inserting PowerLeap™ in a Standard or 80487SX Socket Align the pins of the processor upgrade with the holes of the socket. If you are installing the processor upgrade in a 238-pin socket (socket 3), make sure that the processor is positioned in the center of the socket.
- Page 24 If the computer does not boot, refer to the “Troubleshooting” section later in this guide. Because PowerLeap™ does not require any software drivers, there is no software installation to perform. However, we recommend that you run the Landmark System Speed Test to compare the performance increase provided by PowerLeap™.
