OR> (PGA370) A physical and electrical specification fOR a motherboardprocessOR socket. Socket 370 uses a square SPGAZIF socket with 370 pins, arranged 37x37 (sometimes described as 19x19). IntelORiginally designed Socket 370 fORPPGA Celeron processORs. Newer Socket 370 motherboards additionally suppORt FC-PGA Celeron and Pentium III processORs. The difference between the two versions is electrical some pins are used differently and voltage requirements have been changed from Intel' s VRM 8.2 to VRM 8.4. In addition, Celeron processORs require a 66 MHz front side bus (FSB), and Pentium III processORs require a 100/133 MHz FSB. Some older Socket 370 motherboards suppORt VRM 8.4 and variable bus speeds, so adapters are available that convert the socket pinout to allow FC-PGA processORs to wORk. VIA' s Cyrix III processOR was designed to wORk with Socket 370 motherboards. {Intel Celeron ProcessOR in PPGA fORm factOR - Integration (http://www.pentium.com/design/quality/celeron/ppga/integration.htm)}. {Pentium III ProcessORs - Design Guidelines (http://www.intel.com/design/PentiumIII/designgd/)}.
