Compatibility and Performance

The PowerStacker 5x86 is capable of running 133 MHz, however, the actual speed and performance delivered depends on your system's bus speed. The PowerStacker will not work in systems with the 486 SLC or DLC processors. The following chart shows how the PowerStacker 5x86 133 MHz will perform based on the system's bus speed and the PowerStacker's clock multiplier (3x or 4x).

The Components

The PowerStacker consists of several main components which include:

  • The Heatsink - Cools the 5x86 processor. Some versions of the PowerStacker required a fan in addition to a heatsink.
  • The 5x86 Processor - The replacement for the 486
  • The Module - Contains the circuitry, switches, pins and 5x86 processor DO NOT attempt to separate any of the PowerStacker's components. Doing so will damage the PowerStacker and void your warranty.

The Dip Switches

The current PowerStacker features two blocks of dip switches. Versions earlier than Rev. E had only one switch block. these switches are set at the factory for the highest speed and compatibility. DO NOT change the default settings without testing in your computer first

Note: PowerStacker's shipped prior to October 1997 are referred to as REV. D and have different dip switch settings than those shown here. Please refer to your Technical Guide or the REV. D settings page for more information on proper settings.

Pin 1 Orientation

Notice that one of the corners on the PowerStacker 5x86 upgrade has a white stripe and beveled edge or other distinguishing mark. This corner signifies Pin 1 and must lineup with Pin 1 on the processor socket. Before removing the old 486 processor, please take note of its Pin 1 location. This will aid you in aligning the PowerStacker in the correct position.

Warn To avoid damage to your computer and/or the upgrade, the Pin 1 on the PowerStacker 5x86 must align with the Pin 1 on the socket.

Bus Speed

Some system boards allow you to alternate the bus speed. If possible set the bus speed to a maximum of 33MHz. This will allow you to run the PowerStacker at 133 MHz. To change the system board's bus speed, consult your owner's manual.

Highest Successful Operation Setting
To achieve the highest level of performance and successful operation,
configure your system board jumpers (see your owner's manual) to:
486 DX 33 MHz - 5 volt

Special Notes

The PowerStacker 5x86 employs the AMD Am5x86™ P-75 processor running 133 MHz. Your BIOS may recognize this upgrade as a 486 microprocessor. After installing the upgrade, run the utilities located on the enclosed disk to verify the speed and performance of your machine.
