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-LAND CPU.

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.

Step 6. Secure excess cable with tie-wrap to ensure

cable does not interfere with fan operation or

contact other components.

This motherboard provides four 240-pin DDR2 (Double Data Rate 2) DIMM slots and

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 identical (the same brand, speed, size and chip-type) DDR2/DDR3 DIMM 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.6), identical DDR2 DIMM pair in Dual Channel B (DDRII_2 and DDRII_4; Orange slots; see p.11 No.7), or identical DDR3 DIMM pair in Dual Channel C (DDR3_A1

and DDR3_B1; Green slots; see p.11 No.8), so that Dual Channel Memory Technol-

ogy 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.

1. If you want to install two memory modules, for optimal compatibil-

ity and reliability, it is recommended to install them in the slots of

the same color. In other words, install them in the set of green

slots (DDR3_A1 and DDR3_B1), 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 acti-

vate the Dual Channel Memory Technology. If only one memory

module is installed in the DDR3 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 DDR3 memory module into DDR2 slot

or install a DDR2 memory module into DDR3 slot; otherwise, this

motherboard and DIMM may be damaged.

5. DDR2 and DDR3 memory modules cannot be installed on this

motherboard at the same time.
