Socket 370 (also known as the PGA370 socket) is a

CPU socket In computer hardware, a CPU socket or CPU slot contains one or more mechanical components providing mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows for placing and replacing the centr ...

design as seen on Slot 1. From late 1999 to late 2000 it was Intel's main desktop socket for 100/133 MHz FSB Coppermine Pentium IIIs. In 2001, the Tualatin Pentium III processors brought changes to the infrastructure which required dedicated Tualatin-compatible motherboards; some manufacturers would indicate this with a blue (instead of white) socket. These late sockets were typically compatible with Coppermine processors, but not older Mendocino Celerons. Some

s that used Socket 370 support

processors in dual CPU configurations (e. g. ABIT BP6). Others allowed the use of a Socket 370 or Slot 1 CPU, although not at the same time. The Via-Cyrix Cyrix III, later renamed the VIA C3, also used Socket 370. Slotkets are available that allows Socket 370 CPUs to be used on

Socket 370 Intel processors mechanical load limits

The weight of a Socket 370 CPU cooler should not exceed 180 grams (6.3 ounces). Heavier coolers may result in damage to the die when the system is improperly handled. Most Intel Socket 370 processors (Pentium III and Celeron) had mechanical maximum load limits which were designed not be exceeded during heat sink assembly, shipping conditions, or standard use. They came with a warning that load above those limits would crack the processor die and make it unusable. The limits are included in the table below.
