1.8Central Processing Unit (CPU)

1.8.1 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 on 0.13 micron process. This processor supports 800*/533/400MHz front side bus (FSB), and allows data transfer rates of 6.4GB/s, 4.2GB/s, and 3.2GB/s, respectively. (*Overclocking mode)

If you installed a CPU with 800MHz FSB, you need to use a PC3200 (400MHz) DDR module listed in the Qualified Vendors List. Otherwise the system will become unstable!

Note in the illustration that the CPU has a

 

Gold Mark

 

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.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.

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

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

4.For more information on Hyper-Threading Technology, visit www.intel.com/ info/hyperthreading.

To use the Hyper-Threading Technology on this motherboard:

1.Install a Pentium 4 CPU that supports Hyper-Threading Technology.

2.Power up the system and enter BIOS Setup. Under the Boot Menu, make sure that the item Hyper-Threading Technology is set to Enabled. The item appears only if you installed a CPU that supports Hyper-Threading Technology. See page 2-17.

3.Reboot the computer.
