2.4Central 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® Pentium® 4 Processor in the 478-pin package with 512KB L2 cache. The Pentium 4 processor features the Intel® NetBurst™ micro-architecture, Hyper- Threading Technology, and 800/533/400MHz system bus. Together, these attributes improve system performance by allowing higher core frequencies, faster execution of integer instructions, and data transfer rates up to 6.4GB/s. The socket will also support the Intel Prescott CPU when available.

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!

Notes on Intel® Hyper-Threading Technology

1.This motherboard supports Intel Pentium 4 CPUs with Hyper- Threading Technology.

2.Hyper-Threading Technology is supported under Windows XP and Linux 2.4.x (kernel) and later versions only. Under Linux, use the Hyper-Threading compliler to compile the code. If you are using any other operating systems, disable the Hyper-Threading Techonology item in BIOS to ensure system stability and performance.

3.It is recommended that you install WinXP Service Pack 1.

4.Make sure to enable the Hyper-Threading Technology item in BIOS before installing a supported operating system.
