Sockect PPGA 370 to Slot 1 Adapter. CPU370 Daughter Card.Supports 66/100 MHz CPU FSB (FRONT SIDE BUS).Supports Single/Dual CPU Operation Mode.Works with all of the slot 1 mainboards. However, almost all motherboards that currently support FSB speeds of 133MHz are Slot 1 - thus the resurgence of the Socket-370 to Slot-1 adapters.
In computer hardware terminology, slotkets, also known as slockets, (both short for slot to socket adapter) are adapters that allow socket-based microprocessors to be used on slot-based motherboards.
Slotkets were first created to allow the use of Socket 8Pentium Pro processors on Slot 1 motherboards. Later, they became more popular for inserting Socket 370IntelCelerons into Slot 1 based motherboards. This lowered costs for computer builders, especially with dual processor machines. High-end motherboards accepting two Slot 1 processors (usually Pentium 2) were widely available, but double-socketed motherboards for the less expensive Socket 370 Celerons were not. The slotkets remained popular in the transition period from Slot to Socket-based Pentium III processors by allowing CPU upgrades in existing Slot 1 motherboards.
Slotkets were never introduced to take advantage of the AMD Athlon processors' transition from the Slot A form factor to the Socket A form factor.
Today, slotkets have largely disappeared, as neither Intel nor AMD currently manufacture CPUs in slot form factors.

Socket 370 (also known as the PGA370 socket) is a CPU socket first used by Intel for Pentium III and Celeron processors to first complement and later replace the older Slot 1 CPU interface on personal computers. The '370' refers to the number of pin holes in the socket for CPU pins.
Socket 370 was replaced by Socket 423 in 2000.
Overview[edit]
Socket 370 started as a budget oriented platform for 66 MHz FSB PPGA Mendocino Celeron CPUs in late 1998, as the move to on-die L2 cache removed the need for a PCB 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 motherboards that used Socket 370 support Intel processors in dual CPU configurations. 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.
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 not properly handled.
Socket 370 Intel processors mechanical load limits[edit]
Most Intel Socket 370 processors (Pentium III and Celeron) have the following mechanical maximum load limits which should not be exceeded during heat sink assembly, shipping conditions, or standard use. Load above those limits will crack the processor die and make it unusable.
| Location | Dynamic | Static |
|---|---|---|
| Die Surface | 890 N (200 lbf) | 222 N (50 lbf) |
| Die Edge | 667 N (100 lbf) | 53 N (12 lbf) |
Socket 370 Intel processors with integrated heat sink mechanical load limits[edit]
All Intel Socket 370 processors with integrated heat sink (Pentium III and Celeron 1.13–1.4 GHz) have the following mechanical maximum load limits which should not be exceeded during heatsink assembly, shipping conditions, or standard use. Load above those limits will crack the processor die and make it unusable.
| Location of integrated heat sink | Dynamic | Static |
|---|---|---|
| surface | 890 N (200 lbf) | 667 N (100 lbf) |
| edge | 556 N (125 lbf) | N/A |
| corner | 334 N (75 lbf) | N/A |
