2-1 CPU Installation

This motherboard provides an 1156-pin DIP, LGA 1156 Land Grid Array socket,
referred to as the LGA 1156 socket.
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.
NOTED! Be sure that there is sufficient air circulation across the processor's
heat sink 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. Locate the LGA
1156 socket and open it by first pulling the level sideways away from the socket then
upward to a 135-degree angle. 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.
When you install the CPU into the LGA 1156 socket, there's no force required CPU
insertion; then press the level to locate position slightly without any extra force.
