CPU Processor Installation
These mainboards support Intel ® Core TM 2 Extreme/ Core TM 2 Quad/ Core TM 2 Duo/ Pentium ®
Extreme Edition/ Pentium ® Processors using a Socket 775. Before building your system, we
suggest you to visit the Intel website and review the processor installation procedures.

CPU Socket 775 Configuration Steps:
1. Locate the CPU socket 775 on
your mainboard and nudge the
lever away from the socket as
shown. Then lift the lever to a
140-degree angle (A). Next, lift up
the iron cover (B).
2. There are 2 distinctive marks
located near the corners of the
socket on the same side as the
lever as shown (C). Match these
marks with the marks on the CPU
and carefully lower the CPU down
onto the socket (D).
3. Replace the iron cover and then
lower the lever until it snaps back
into position (E). This will lock
down the CPU (F).
4. Smear thermal grease on the top of the CPU. Lower the
CPU fan onto the CPU/CPU socket and secure it using the
attachments or screws provided on the fan. Finally, attach
the fan power cord to the CPUFAN header.

Attention
DO NOT touch the CPU pins in case they are damaged. Also, make sure
that you have completed all installation steps before powered on the
system. Finally, double-check that the cooling fan is properly installed and
the CPU fan power cord is securely attached, in case your CPU and other
sensitive components are damaged because of high temperatures.
