Intel486 OverDrive

Intel DX2-66 MHz OverDrive

Intel 486 OverDrive (code name P23T ) is a microprocessor designed to upgrade systems based on Intel 80486 microprocessors .

Basic Information

In motherboards under the i486SX for desktop systems, two processor sockets were sometimes installed. The second was designed to install the i487 mathematical coprocessor or OverDrive processor. At the same time, i487 added hardware support for floating-point calculations, and OverDrive, in addition, increased system performance to the level of a DX2 processor of the corresponding frequency. In practice, this technology is not widely used.

Intel 486 OverDrive processors usually had better quality characteristics than the “regular” 486 processors of the same generation. Key Benefits of Intel 486 OverDrive Processors:

  • OverDrive processors included built-in voltage regulators;
  • Supported a write-back cache instead of a write-through cache
  • had a fixed radiator and were able to work without forced air cooling.
