ASRock P67 Transformer [19/61] Installation of memory modules dimm

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-

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

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

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

DDR3_B1; white slots; see p.12 No.5), so that Dual Channel Memory Technol-

ogy can be activated. This motherboard also allows you to install four DDR3

DIMMs for dual channel configuration, and please install identical DDR3

DIMMs in all four slots. You may refer to the Dual Channel Memory Con gura-

tion Table below.

For the con guration (2), 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 white

slots (DDR3_A1 and DDR3_B1).

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

into DDR3 slot;otherwise, this motherboard and DIMM may be

damaged.

4. Please install the memory module into the white slot (DDR3_B1) for

the rst priority.
