2.3 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)

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_2; Yellow slots;

see p.13/14 No.6) or identical DDR2 DIMM pair in Dual Channel B (DDRII_3 and

DDRII_4; Orange slots; see p.13/14 No.7), 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.

Dual Channel Memory Configurations

DDRII_1 DDRII_2 DDRII_3 DDRII_4

(Yellow Slot) (Yellow Slot) (Orange 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 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_1 and DDRII_2), or in the set of orange slots

(DDRII_3 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_3, 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.
