The P8SCT motherboard supports single Intel Pentium 4 Processor (the Prescott Processor) in the 775-Land Grid Array Package (LGA 775) at a system bus speed of 800 MHz. It also supports Intel Celeron Processor at a bus speed of 533MHz. The Pentium 4 Processor in the 775-Land Grid Array Package is housed in a Flip-Chip Land Grid Array (FC-LGA4) package that interfaces with the motherboard via an LGA775 socket. The package consists of a processor core mounted on a substrate land-carrier. An integrated heat spreader (IHS) is attached to the package substrate and core and serves as the contacting surface for processor component thermal solutions, such as a heat sink.
