Socket 4 was released around 1993 and housed the very first real Pentium processor. Very few different CPU's have been made to fit this socket, which is limited to the Pentium 60MHz, the Pentium 66MHz and the obscure Pentium Overdrive which ran at either 120MHz or 133MHz. Because of the limited variety of CPU's manufactured for this socket and the limited speed options these motherboards provided, Socket 4 is a far less flexible platform when compared to Socket 3 or Socket 7. Socket 4 supported the then new 60MHz FSB and 66MHz FSB (even though some Socket 4 motherboards were made that had slower FSB's like 50MHz and 40MHz). Usually Socket 4 motherboards were fitted with ISA and PCI slots, though some VLB slotted Socket 4 motherboards were made. Socket 4 motherboards used either EDO or FPM memory modules and the memory modules had to be fitted in pairs where in it's predecessor, single modules were used. This was because Socket 4 was the first x86 motherboard that had a 64-bit memory bus (486 and earlier used a 32-bit, or a 16-bit memory bus).

'''Today:''' These days Socket 4 isn't the best basis for a retro rig, as there are better alternatives out there. Socket 3 (486) boards are just as fast as Socket 4 and offer more flexibility then Socket 4, which generally speaking is locked at either 60MHz or 66MHz. Socket 7 (and Super 7) on the high end offer much more flexibility also and can be slowed down to almost the same speed using different processors and/or speed settings. Last but not least, Socket 4 motherboards aren't all that common as Socket 4 was so quickly replaced by Socket 5 and Socket 7.

Socket 4

Socket 4

Socket 4 was released in 1993 and was used for the initial Pentium "P5" processors. This includes the Pentium 60MHz and 66MHz in addition to Pentium Overdrive 120MHz and 133MHz. There are no other CPU options for this socket. Usually Socket 4 motherboards use ISA and PCI slots, though some VLB-equipped boards were made. Socket 4 motherboards used either EDO or FPM 72-pin SIMM modules, fitted in pairs to match the 64-bit memory bus.

All Socket 4 motherboards were made as AT motherboards or as proprietary boards.

Today: Socket 4 is an uncommon choice because of its poor CPU choices and old chipsets have low performance and old feature-sets.
