The Pentium OverDrive 83

The Pentium OverDrive chip requires a 237 or 238 pin PGA processor socket. When the Pentium OverDrive chip finally arrived it was discovered not all the System Boards manufactured with a Pentium OverDrive socket would actually work with the chip. I can not guarantee compatibility with your board, please check before purchasing. Questions or concerns just ask "Before purchasing" Thank You

The Pentium OverDrive chips have a fan built into a heatsink on top of the chip but the 486 OverDrive chips only have the heatsink and do not require a fan on the processor chip.
