2.5 Installation of Memory Modules (DIMM)

This motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM

slots, and supports Dual Channel Memory Technology. For dual channel con-

fi guration, you always need to install identical (the same brand, speed, size

and chip-type) DDR3 DIMM pair in the slots of the same color. In other words,

you have to install identical DDR3 DIMM pair in Dual Channel A (DDR3_A1

and DDR3_B1; Red slots; see p.16 No.5) or identical DDR3 DIMM pair in Dual

Channel B (DDR3_A2 and DDR3_B2; Black slots; see p.16 No.6), so that Dual

Channel Memory Technology can be activated. This motherboard also allows

you to install four DDR3 DIMMs for dual channel confi guration, and please in-

stall identical DDR3 DIMMs in all four slots. You may refer to the Dual Channel

Memory Confi guration Table below.

For the confi guration (3), please install identical DDR3 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 red slots

(DDR3_A1 and DDR3_B1), or in the set of black slots (DDR3_A2

and DDR3_B2).

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

DDR3_A1 and DDR3_A2, it is unable to activate the Dual Channel

Memory Technology .

4. It is not allowed to install a DDR or DDR2 memory module into

DDR3 slot; otherwise, this motherboard and DIMM may be dam-

aged.

5. Some DDR3 1GB double-sided DIMMs with 16 chips may not work

on this motherboard. It is not recommended to install them on this

motherboard.
