2. Central Processing Unit (CPU)
The motherboard comes with a surface mount 478-pin Zero Insertion Force (ZIF)
®
socket. The socket is designed for the Intel
Pentium
processor in the 478-pin package with 512KB L2 cache. This processor supports
800/533/400MHz front side bus (FSB), and allows data transfer rates of 3.2GB/s,
2.1GB/s, and 1.6GB/s.
Follow these steps to install a CPU.
1. Locate the 478-pin ZIF socket on the motherboard.

2. Unlock the socket by pressing the
lever sideways, then lift it up to a 90°-
100° angle.
Make sure that the socket lever is lifted
up to 90°-100° angle, otherwise the
CPU does not fit in completely.
3. Position the CPU above the socket
such that its marked corner matches
the base of the socket lever.
4. Carefully insert the CPU into the
socket until it fits in place.

Gold Mark
The CPU fits only in one correct
orientation. DO NOT force the CPU
into the socket to prevent bending
the pins and damaging the CPU!
5. When the CPU is in place, push
down the socket lever to secure the
CPU. The lever clicks on the side tab
to indicate that it is locked.
6. Install a CPU heatsink and fan
following the instructions that came
with the heatsink package.
7. Connect the CPU fan cable to the
CPU_FAN1 connector on the
motherboard.
