'''Slot 2''' refers to the physical and electrical specification for the 330-lead [[Single Edge Contact Cartridge]] (or edge-connector) used by [[Intel]]'s [[Xeon#Pentium II Xeon|Pentium II Xeon]] and [[Xeon#Pentium III Xeon|Pentium III Xeon]].

When first introduced, [[Slot 1]] [[Pentium II]]s were intended to replace the [[Intel P5|Pentium]] and [[Pentium Pro]] processors in the home, desktop, and low-end [[symmetric multiprocessing]] (SMP) markets. The Pentium II Xeon, which was aimed at multiprocessor workstations and servers, was largely similar to the ordinary Pentium II, being based on the same [[P6 (microarchitecture)|P6]] [[Deschutes (microprocessor)|Deschutes]] core, differing by offering the choice of L2 cache capacity of 1024 or 2048&nbsp;KB besides 512&nbsp;KB,<ref>In the context to semiconductor memory such as cache, KB refers to 2<sup>10</sup> bytes</ref> and by operating it at the core frequency (the Pentium II used cheaper third-party SRAM chips, running at 50% of CPU speed, to reduce cost).

Because the design of the 242-lead Slot 1 connector did not support the full-speed L2 cache of the Xeon, an extended 330-lead connector was developed. This new connector, dubbed 'Slot 2', was used for Pentium II Xeon (codenamed 'Drake') and Pentium III Xeon (codenamed 'Tanner' and 'Cascades'). Slot 1 was finally replaced by the [[Socket 370]] with the revised [[Pentium III]] codenamed [[Tualatin (microprocessor)|Tualatin]] for the low power dual-processor servers, and Slot 2 by [[Socket 603]] with [[Pentium 4]]-based [[Xeon#Foster|Xeon (codenamed Foster)]] for workstations and quad-processor servers.
