2.5 Installation of Memory Modules (DIMM)

4Core1333-GLAN

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) DDR2 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.10 No.7) or identical DDR2 DIMM pair in Dual Channel B
(DDRII_2 and DDRII_4; Orange slots; see p.10 No.8), so that Dual 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

(DS: Double Side, SS: Single Side)

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 acti-
vate 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 and DIMM may be damaged.
