2-3-2 About INTEL PENTIUM 4 478-PIN CPU
This motherboard provides a 478-pin surface mount, Zero Insertion Force (ZIF) socket, referred
to as the mPGA478B socket supports Intel Pentium 4 processor in the 478 Pin package utilizes
Flip-Chip Pin Grid Array (FC-PGA2) package technology.
The CPU that comes with the motherboard should have a cooling FAN attached to prevent
overheating. If this is not the case, then purchase a correct cooling FAN before you turn on your
system.
WARNING! Be sure that there is sufficient air circulation across the processor’s heatsink
and CPU cooling FAN is working correctly, otherwise it may cause the
processor and motherboard overheat and damage, you may install an auxiliary
cooling FAN, if necessary.
To install a CPU, first turn off your system and remove its cover. To locate the ZIF socket and
open it by first pulling the level sideways away from the socket then upward to 90-degree. Insert
the CPU with the correct orientation as shown below. The notched corner should point toward
the end of the level. Because the CPU has a corner pin for two of the four corners, the CPU will
only fit in the orientation as shown.
