Socket 370
<hardware, standard, processor>
(PGA370) A physical and electrical specification for a motherboard processor socket. Socket 370 uses a square SPGA ZIF socket with 370 pins, arranged 37x37 (sometimes described as 19x19).
Intel originally designed Socket 370 for PPGA 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.
