Intel Celeron SL376 366MHz Slot 1 SEPP Processor w/ Heatsink 366/66

The Intel Celeron SL376 is a 366MHz Slot 1 processor built on Intel's "Mendocino" core, which integrated 128KB of L2 cache directly onto the processor die — a key improvement over earlier Covington-core Celerons that shipped with no L2 cache at all. It uses the SEPP (Single Edge Processor Package) form factor and seats into a standard Slot 1 (SC242) connector. This unit ships with its aluminum finned heatsink attached; no fan is included.

Applications

The Slot 1 Celeron line, introduced in 1998, was Intel's value-tier response to the Pentium II and was widely used in budget desktop PCs and entry-level workstations of the late 1990s. The Mendocino-core Celerons — running at 300A, 333, 366, 400, 433, and 466 MHz — became popular not just in budget builds but also among enthusiasts, as many proved highly overclockable on 100MHz FSB motherboards. The SL376 at 366MHz was part of this highly regarded generation. Today these processors are sought by collectors and by maintainers of period-correct late-1990s systems based on Intel 440BX, 440LX, and 440EX chipset motherboards. Compatible with any Slot 1 motherboard that accepts Celeron SEPP modules, making it a straightforward drop-in replacement for systems of that era.
