2.4.1 Overview
The motherboard comes with a surface mount 478-pin Zero Insertion
Force (ZIF) socket. This socket is specifically designed for the Intel
®
Pentium
®
4 478/Northwood Processor.
The Intel Pentium 4 Processor in the 478-pin package uses the Flip-Chip
Pin Grid Array 2 (FC-PGA2) package technology, and includes the Intel
®
NetBurst™ micro-architecture. The Intel NetBurst micro-architecture
features the hyper-pipelined technology, rapid execution engine, 400 /
533MHz system bus, and execution trace cache. Together, these attributes
improve system performance by allowing higher processor frequencies,
faster execution of integer instructions, and a data transfer rates of 3.2 and
4.2GB/s.
Note in the illustration that the CPU has a gold triangular mark on one
corner. This mark indicates the processor Pin 1 that should match a
specific corner of the CPU socket.
Incorrect installation of the CPU into the socket may bend the pins and
severely damage the CPU!
