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.

Socket 370

The motherboard receptacle for Pentium II and III CPUs. Socket 370 accepts a 370-pin PPGA (plastic pin grid array) chip package. Socket 370 chips and motherboards cost less to manufacture than the more elaborate Single Edge Cartridge (SEC) and Slot 1 receptacle introduced with the Pentium II. See Super7.

Socket 370 and Slot 1
This motherboard supports both types of sockets for Pentium III chips.
