Central Processing Unit (CPU)

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, 400MHz
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 rate of 3.2GB/s.

Incorrect installation of the CPU into the socket may bend the pins and
severely damage the CPU!
