Central Processing Unit (CPU)
2.4.1 Overview
The motherboard comes with a surface mount 478-pin Zero Insertion
Force (ZIF) socket. The socket is designed for the Intel
®
Pentium4™
Processor in the 478-pin package with 512KB L2 cache. The processor
includes the Intel
®
NetBurst™ micro-architecture that 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 core frequencies, faster execution of
integer instructions, and data transfer rate of up to 3.2/4.2GB/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!
