1.6 Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA775 socket designed for
the Intel® Pentium® 4 processor in the 775-land package.
•
Your boxed Intel® Pentium® 4 LGA775 processor package should
come with installation instructions for the CPU, fan and heatsink
assembly. If the instructions in this section do not match the CPU
documentation, follow the latter.
• Upon purchase of the motherboard, make sure that the PnP cap is
on the socket and the socket pins are not bent. Contact your
retailer immediately if the PnP cap is missing, or if you see any
damage to the PnP cap/socket pins/motherboard components.
ASUS will shoulder the cost of repair only if the damage is shipment/
transit-related.
• Keep the cap after installing the motherboard. ASUS will process
Return Merchandise Authorization (RMA) requests only if the
motherboard comes with the cap on the LGA775 socket.
•
The product warranty does not cover damage to the socket pins
resulting from incorrect CPU installation/removal, or misplacement/
loss/incorrect removal of the PnP cap.

• This motherboard supports Intel® Pentium® 4 CPUs in the 775-land
package with Hyper-Threading Technology.
• Hyper-Threading Technology is supported under Windows® XP/2003
Server and Linux 1.7.x (kernel) and later versions only. Under Linux,
use the Hyper-Threading compiler to compile the code. If you are
using any other operating systems, disable the Hyper-Threading
Technology item in the BIOS to ensure system stability and
performance.
• Installing Windows® XP Service Pack 1 or later is recommended.
• Make sure to enable the Hyper-Threading Technology item in BIOS
before installing a supported operating system.
• For more information on Hyper-Threading Technology, visit
www.intel.com/info/hyperthreading.
To use the Hyper-Threading Technology on this motherboard:
®
1. Install an Intel
Pentium® 4 CPU in the 775-land package that supports
Hyper-Threading Technology.
2. Power up the system and enter the BIOS Setup (see Chapter 2: BIOS
setup). Under the Advanced 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.
3. Reboot the computer.

Installing the CPU heatsink and fanInstalling the CPU heatsink and fan
Installing the CPU heatsink and fan
Installing the CPU heatsink and fanInstalling the CPU heatsink and fan
The Intel® Pentium® 4 LGA775 processor requires a specially designed
heatsink and fan assembly to ensure optimum thermal condition and
performance.
•
When you buy a boxed Intel® Pentium® 4 processor, the package
includes the CPU fan and heatsink assembly. If you buy a CPU
separately, make sure that you use only Intel®-certified
multi-directional heatsink and fan.
•
Your Intel® Pentium® 4 LGA775 heatsink and fan assembly comes in
a push-pin design and requires no tool to install.
•
If you purchased a separate CPU heatsink and fan assembly, make
sure that you have properly applied Thermal Interface Material to the
CPU heatsink or CPU before you install the heatsink and fan
assembly.
Make sure that you have installed the motherboard to the chassis before
you install the CPU fan and heatsink assembly.
To install the CPU heatsink and fan:
1. Place the heatsink on top of the
installed CPU, making sure that
the four fasteners match the
holes on the motherboard.
Orient the heatsink and fan
assembly such that the CPU
fan cable is closest to the
CPU fan connector.
Make sure to orient each fastener with the narrow end of the groove
pointing outward. (The photo shows the groove shaded for emphasis.)
