x86 processor socket

x86 processor socket

(hardware, standard)One of the series of standard socketsinto which you can plug various x86 microprocessors.These vary in the number of pins, package, voltages, busspeeds, and supported processors. Motherboards often haveclock multipliers so that the processor runs at a multipleof the bus speed.

Socket 1, 169 pin LIF/ZIF PGA (17x17), 5v, 16-33 MHz486 SX, 486 DX, 486 DX2, DX4 Overdrive. Socket 1 wasthe first standard Intel 486 socket.

Socket 2, 238 pin LIF/ZIF PGA (19x19), 5v, 25-50 MHz 486 SX,486 DX, 486 DX2, 486 DX4, DX4 & Pentium Overdrive. UpdatedSocket 1, added support for Pentium Overdrive processors.

Socket 3, 237 pin LIF/ZIF PGA (19x19), 3.3/5v, 25-50 MHz 486SX, 486 DX, 486 DX2, 486 DX4, DX4 & Pentium Overdrive.Supports 5V & 3.3V processors, considered the latest 486socket.

Socket 4, 273 pin LIF/ZIF PGA (21x21), 5v, 60/66 MHz Pentium60/66 and Pentium Overdrive, only 5v.

Socket 5, 296 pin LIF/ZIF, 320 pin LIF/ZIF SPGA (19x19 or37x37), 3.3v, 50/60/66 MHz Pentium 75 - 133MHz, PentiumOverdrive, only 3.3v.

Socket 6, 235 pin ZIF PGA (19x19), 3.3v, 25-40MHz. Unpopularadvanced Socket 3, rarely seen / paper spec 486 DX4, PentiumOverdrive, only 3.3v.
