2.4 Installation of CPU Fan and Heatsink
This motherboard is equipped with 1155-Pin socket that supports Intel 1155-Pin
CPUs. Please adopt the type of heatsink and cooling fan compliant with Intel 1155-
Pin CPU to dissipate heat. Before you install the heatsink, you need to spray ther-
mal interface material between the CPU and the heatsink to improve heat dissipa-
tion. Ensure that the CPU and the heatsink are securely fastened and in good con-
tact with each other. Then connect the CPU fan to the CPU_FAN connector (CPU_
FAN1, see page 14, No. 5).
For proper installation, please kindly refer to the instruction manuals of your
CPU fan and heatsink.
Below is an example to illustrate the installation of the heatsink for 1155-Pin CPUs.
Step 1. Apply thermal interface material onto the cen-
ter of the IHS on the socket’s surface.
Step 2. Place the heatsink onto the socket. Ensure
that the fan cables are oriented on side closest
to the CPU fan connector on the motherboard
(CPU_FAN1, see page 14, No. 5).
Step 3. Align fasteners with the motherboard through-
holes.
Step 4. Rotate the fastener clockwise, then press
down on fastener caps with thumb to install
and lock. Repeat with remaining fasteners.
If you press down the fasteners without rotating them clockwise, the
heatsink cannot be secured on the motherboard.
Step 5. Connect fan header with the CPU fan connector on the motherboard.
Step 6. Secure redundant cable with tie-wrap to ensure the cable does not
interfere with fan operation or contact other components.

2.5 Installation of Memory Modules (DIMM)
This motherboard provides two 240-pin DDR3 (Double Data Rate 3) DIMM slots,
and supports Dual Channel Memory Technology. For dual channel configuration,
you always need to install two identical (the same brand, speed, size and chip-
type) memory modules in the DDR3 DIMM slots to activate Dual Channel Memory
Technology. Otherwise, it will operate at single channel mode.
1. It is not allowed to install a DDR or DDR2 memory module into a
DDR3 slot; otherwise, this motherboard and DIMM may be
damaged.
2. If you install only one memory module or two non-identical
memory modules, it is unable to activate Dual Channel
Memory Technology.
3. Some DDR3 1GB double-sided DIMMs with 16 chips may not
work on this motherboard. It is not recommended to install them
on this motherboard.
Installing a DIMM
Please make sure to disconnect power supply before adding or
removing DIMMs or the system components.
Step 1. Unlock a DIMM slot by pressing the retaining clips outward.
Step 2. Align a DIMM on the slot such that the notch on the DIMM matches the
break on the slot.
The DIMM only ts in one correct orientation. It will cause permanent
damage to the motherboard and the DIMM if you force the DIMM into
the slot at incorrect orientation.
Step 3. Firmly insert the DIMM into the slot until the retaining clips at both ends
fully snap back in place and the DIMM is properly seated.
