Installing An Overdrive Module - Epson Progression User Manual

Installing on OverDrive Module
If you have the 486SX/25 or 486DX/33 CPU card, you can
enhance your system's performance by installing an Intel
OverDrive module on the card. This allows you to effectively
double the internal clock speed of your computer's
microprocessor with a very simple upgrade procedure.
Note
Although there is an OverDrive socket on the 486DX2/66
card, there is no OverDrive module available for it at this
time.
The type of module you choose depends on the CPU card you
have, as shown in the table below.
Available OverDrive modules

486SX/25
486DX/33
If you install this module, you cannot also Install a 487SX/25 microprocessor
chip because both options require the same socket.
** Check with your dealer on the availability of this chip.
You may prefer to have your dealer install the OverDrive
module for you because it can be easily damaged if installed
incorrectly. If you decide to install it yourself, be sure to read
any documentation that came with it, especially any
precautionary information. Then follow the instructions
provided with the OverDrive module as well as those given in
the appropriate section below to install it on your CPU card.
