a series of standard sockets

created by Intel. various x86 microprocessors

were plugged.

Socket 1 was a 169 pin.

Socket 2 was one of the series of

sockets into which various x86

microprocessorswere plugged.

It was a 238-pin.

SOCKET 3

It was commonly 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.

INTRODUCE 1991.

SOCKET 4

Socket 4, presented in 1993, was the

first CPU socket designed for the

early Pentium processors

Socket 4 was the only 5-volt socket

for the Pentium. After Socket 4, Intel

switched to the 3.3-volt-powered

Socket 5. Socket 4 does support a

special Pentium OverDrive, which

allows running at 120 MHz (for the 60

MHz Pentium) or 133 MHz (for the 66

MHz Pentium).[1]

CPUs. Socket 8 also has a unique pin

arrangement pattern.

CPU, the transition from socket to slot had

become necessary, because the CPU's

core and the cache are two different chips

on a shared circuit board.

Socket 563 is a microPGA CPU socketused exclusively for low-power (16 Wand 25 W TDP) Athlon XP-Mprocessors (Models 8 & 10.

This socket can usually be found in

laptops and requires a low-powermobile part in a special 563-pin PGApackage which is different from theSocket A (462 pin) package used forother Athlon processors.

There are desktop computermotherboards equipped with Socket

563. PCChips is know

n to havemarketed such a board, the M863GVer3 (actually made by ECS), bundledwith a socket 563 processor and aheatsink.

Replaces Socket 479.

Socket M is not pin-compatible withthe older desktop Socket 478 or thenewer mobile Socket P; it is alsoincompatiblewith most versions of

the older mobile Socket 479. PentiumIII-M processors designed for the firstversion of Socket 479 will physicallyfit into a Socket M, but areelectrically incompatiblewith it

Its FSB can run at 400, 533, 667, 800,or 1066 MT/s, and it can be throttledup or down to save power, given thatall Socket M CPUs support EIST.Socket P has 478 pins, but is not pin-compatiblewith Socket M or Socket

478. Socket P is also know

n as a 478-pin Micro FCPGA or FCPGA-478.
