Socket 4 Motherboards

Socket 4

Socket 4

Socket 4 was released in 1993 and was used for the initial Pentium "P5" processors. The initial processors were based on the P5 core and include the Pentium 60MHz and 66MHz. Intel did release two Pentium Overdrive CPUs based on P54, operating at 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.
