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)

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_A1 and DDRII_B1; Yellow

slots; see p.2/3 No.6) or identical DDR2 DIMM pair in Dual Channel B (DDRII_A2

and DDRII_B2; Orange slots; see p.2/3 No.7), so that Dual Channel Memory Tech-

nology 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.

* For the configuration (3), please install identical DDR2 DIMMs in all four slots.

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 either in the set of

yellow slots (DDRII_A1 and DDRII_B1), or in the set of orange

slots (DDRII_A2 and DDRII_B2).

2. If only one memory module or three memory modules are in-

stalled 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_A1 and DDRII_A2, 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.
