Socket 3 was a series of CPU Sockets for various x86 microprocessors. It was sometimes found alongside a secondary socket designed for a math coprocessor chip, in this case the 487. Socket 3 resulted from Intel's creation of lower voltage microprocessors. An upgrade to Socket 2, it rearranged the pin layout and omitted one pin so that 3.3 V processors could not be plugged into older 5 V only sockets.
Socket 3 was a 237-pin low insertion force (LIF) or zero insertion force (ZIF) 19×19 pin grid array (PGA) socket suitable for the 3.3 V and 5 V, 25–50 MHz Intel 486 SX, 486 DX, 486 DX2, 486 DX4, 486 OverDrive and Pentium OverDrive processors as well as AMD Am486, Am5x86 and Cyrix Cx5x86 processors.[1]
