Installation of CPU Fan and Heatsink
This motherboard is equipped with 775-Pin socket that supports Intel 775-LAND CPU.
Please adopt the type of heatsink and cooling fan compliant with Intel 775-LAND CPU
to dissipate heat. Before you installed the heatsink, you need to spray thermal
interface material between the CPU and the heatsink to improve heat dissipation.
Ensure that the CPU and the heatsink are securely fastened and in good contact with
each other. Then connect the CPU fan to the CPU_FAN connector (CPU_FAN1, see
page 11, No. 3).
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 775-LANDCPU.
Step 1. Apply thermal interface material onto center
of IHS on the socket surface.
Step 2. Place the heatsink onto the socket. Ensure
fan cables are oriented on side closest to the
CPU fan connector on the motherboard
(CPU_FAN1, see page 11,No. 3).
Step 3. Align fasteners with the motherboard
throughholes.
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.

2.5 Installation of Memory Modules (DIMM)
This motherboard provides four 240-pin DDR2 (Double Data Rate 2)DIMM slots,
and supports Dual Channel Memory Technology. For dual channel configuration,
you always need to install identical (the same brand, speed, size and chip-
type) DDR2DIMM pair in the slots of the same color. In other words, you have to
install identical DDR2 DIMM pair in Dual Channel A (DDRII_1 and DDRII_3;
Yellow slots; see p.11 No.5) or identical DDR2 DIMM pair in Dual Channel B
(DDRII_2 andDDRII_4; Orange slots; see p.11No.6), so thatDual Channel Memory
Technology can be activated. This motherboard also allows you to install four
DDR2 DIMMs for dual channel configuration, and please install identical DDR2
DIMMs in all four slots. You may refer to the Dual Channel Memory Configuration
Table below.
Dual Channel Memory Configurations
DDRII_1 DDRII_2 DDRII_3 DDRII_4
(Yellow Slot) (Orange Slot) (Yellow Slot) (Orange Slot)
(1) Populated - Populated -
(2) - Populated - Populated
(3)* Populated Populated Populated Populated
* For the configuration (3), please install identical DDR2 DIMMs in all four
slots.
1. If you want to install two memory modules, for optimal compatibility
and reliability, it is recommended to install them in the slots of the
same color. In other words, install them either in the set of yellow
slots (DDRII_1 and DDRII_3), or in the set of orange slots (DDRII_2
and DDRII_4).
2. If only one memory module or three memory modules are installed
in the DDR2 DIMM slots on this motherboard, it is unable to activate
the Dual Channel Memory Technology.
3. If a pair of memory modules is NOT installed in the same Dual
Channel, for example, installing a pair of memory modules in DDRII_1
and DDRII_2, it is unable to activate the Dual Channel Memory
Technology .
4. It is not allowed to install a DDR memory module into DDR2 slot;
otherwise, this motherboard andDIMM may be damaged.
5. This motherboard supports two double-sided or four single-sided
DIMMs. Therefore, if you install four DDR2 DIMMs, you can only
adopt four single-sided DIMMs.
