Intel Pentium II 350MHz Processor 512KB Cache Slot 1 SL2U3 80523PY350512PE

Intel Pentium II 350MHz Processor 512KB Cache Slot 1 SL2U3 80523PY350512PE

The Intel Pentium II 350MHz is a sixth-generation x86 processor using Intel's Slot 1 (SC242) interface. It runs at 350MHz on a 100MHz front-side bus with 512KB of on-die L2 cache running at half-core speed. The S-spec is SL2U3, part number 80523PY350512PE, and it carries IBM FRU 02K2776. This is new old stock — unused and uninstalled.

Applications

The Pentium II was Intel's mainstream desktop and workstation processor from 1997 through 1999, succeeding the Pentium Pro and its older Pentium MMX line. The Slot 1 form factor replaced the older Socket 7 and Socket 8 designs, using a cartridge-style edge connector to accommodate the large L2 cache chips on the processor substrate. The 350MHz Deschutes variant ran on a 100MHz FSB introduced with the 440BX chipset, making it compatible with motherboards using Intel's 440BX, 440LX, and select VIA Apollo Pro chipsets. It was widely used in desktop PCs and entry-level workstations of the late 1990s running Windows 95, Windows 98, Windows NT 4.0, and early Windows 2000 builds. Today this processor is sought by collectors and by technicians maintaining or restoring late-1990s legacy systems, IBM Netfinity servers, and compatible workstations that still require Slot 1 hardware.
