SEPP - Computer Definition
(Single Edge Processor Package) A CPU module from Intel that held Celeron chips and their L2 cache chips. The SEPP, which plugged into Slot 1 on the motherboard, was the bare printed circuit board. For the Pentium II and Pentium III chips, the board was encased in a metal housing and became the single edge contact cartridge (SECC). See Slot 1 and SECC.
