2.4 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
®
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!

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.
