2.3 Installation of Memory Modules (DIMM)

P4Dual-880Pro motherboard provides four 184-pin DDR (Double Data Rate) 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) DDR DIMM pair in the slots of the same color. In other words,

you have to install identical DDR DIMM pair in Dual Channel A (DDR1 and

DDR3; Blue slots; see p.10 No.6) or identical DDR DIMM pair in Dual Channel B

(DDR2 and DDR4; Black slots; see p.10 No.7), so that Dual Channel Memory

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

DDR DIMMs for dual channel configuration, and please install identical DDR

DIMMs in all four slots. You may refer to the Dual Channel Memory Configuration

Table below.

(3)* Populated Populated Populated Populated

* For the configuration (3), please install identical DDR 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 blue slots

(DDR1 and DDR3), or in the set of black slots (DDR2 and DDR4).

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

in the DDR 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 DDR1

and DDR2, it is unable to activate the Dual Channel Memory Tech-
