5.2. Installing the CPU
The APOLLO III can adapt Socket 370 Intel Celeron or
Pentium III CPU. Upgrading the CPU can increase the system
performance. When Pentium III 1GB 133MHz is used with
the system, it is suggested to attach another system cooling
fan at the right side of the system compartment to prevent
the system from overheating.
The APOLLO’s motherboard provides one 370-pin ZIF socket
(Socket 370). The CPU must come with a CPU fan with a heat
sink on to avoid overheating.
To install a CPU or upgrade a new CPU, follow the instructions
below.
1. If there is an existing CPU on the socket, remove the CPU
cooling fan first. Then remove the CPU by pulling the
lever out a little and raising it, then lifting out the existing
CPU from the socket.
2. To insert the CPU into the socket, the notch on the corner
of the CPU (the corner with golden dot) should point
toward the end of the socket lever. If the insertion of the
CPU to the socket is not easy, check whether the CPU pins
correspond with the holes on the socket.
3. After insert the CPU into the socket, pull the lever down to
make sure the CPU is in place.
4. The CPU cooling fan comes with a 3-pin power cable.
Connect the power cable to the 3-pin power connector on
the motherboard.
5. There are two white clips on the CPU socket. Make sure
the cooling CPU fan clips click into place.
