2.3Central Processing Unit (CPU)

2.3.1Overview

The motherboard comes with a surface mount 478-pin Zero Insertion Force (ZIF) socket designed for the Intel® Pentium® 4 Processor.

Take note of the marked corner (with

gold triangle) on the CPU. This markGold Mark should match a specific corner on the

socket to ensure correct installation.

Your boxed Intel® Pentium® 4 processor package should come with installation instructions for the CPU, heatsink, and the retention mechanism. If the instructions in this section do not match the CPU documentation, follow the latter.

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