2.3.2 Installling the CPU heatsink and fan
The Intel® Pentium® 4/Intel® Pentium® D LGA775 processor requires a
specially designed heatsink and fan assembly to ensure optimum thermal
condition and performance.
•
•
Install the motherboard to the chassis before you install the CPU fan
and heatsink assembly
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 a Thermal Interface Material is properly applied to the CPU heatsink
or CPU before you install the heatsink and fan 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.

2.6 Jumpers
1 . Clear RTC RAM (CLRTC)
This jumper allows you to clear the Real Time Clock (RTC) RAM in
CMOS. You can clear the CMOS memory of date, time, and system
setup parameters by erasing the CMOS RTC RAM data. The onboard
button cell battery powers the RAM data in CMOS, which include
system setup information such as system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Remove the onboard battery.
3. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the
cap on pins 2-3 for about 5~10 seconds, then move the cap back to
pins 1-2.
4. Re-install the battery.
5. Plug the power cord and turn ON the computer.
6. Hold down the <Del> key during the boot process and enter BIOS
setup to re-enter data.
Except when clearing the RTC RAM, never remove the cap on CLRTC
jumper default position. Removing the cap will cause system boot failure!
