Central Processing Unit: CPU
The mainboard supports Intel
®
Pentium
®
4 processor in the 478 pin
package. The mainboard uses a CPU socket called PGA478 for easy CPU
installation. When you are installing the CPU,
make sure the CPU has a heat
sink and a cooling fan attached on the top to prevent overheating.
If you do not
find the heat sink and cooling fan, contact your dealer to purchase and install
them before turning on the computer.
CPU Installation Procedures
1.
Pull the lever sideways away
from the socket. Make sure
to raise the lever up to a 90-
degree angle.
2. Look for the cut edge. The cut
edge should point towards the
lever pivot. The CPU can only
fit in the correct orientation.
3. If the CPU is correctly
installed, the pins should be
completely embedded into the
socket and can not be seen.
Please note that any violation
of the correct installation
procedures may damage your
mainboard.
4.
As the CPU is likely to move
while the lever is being closed,
always close the lever with
your fingers pressing tightly
on top of the CPU to make sure
the CPU is properly and
completely embedded into the
socket.
