2.5 Installation of Memory Modules (DIMM)

2Core1333-2.66G motherboard provides two 240-pin DDRII (Double Data Rate)

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

configuration, you always need to install two identical (the same brand, speed,

size and chip-type) memory modules in the DDRII DIMM slots to activate Dual

Channel Memory Technology. Otherwise, it will operate at single channel mode.

It is not allowed to install a DDR memory module into DDRII slot;

otherwise, this motherboard and DIMM may be damaged.

If you install only one memory module or two non-identical memory

modules, it is unable to activate the Dual Channel Memory Technology.

Installing a DIMM

Please make sure to disconnect power supply before adding or

removing DIMMs or the system components.

Step 1.

Unlock a DIMM slot by pressing the retaining clips outward.

Step 2.

Align a DIMM on the slot such that the notch on the DIMM matches the break

on the slot.

The DIMM only fits in one correct orientation. It will cause permanent

damage to the motherboard and the DIMM if you force the DIMM into the

slot at incorrect orientation.

Step 3.

Firmly insert the DIMM into the slot until the retaining clips at both ends fully

snap back in place and the DIMM is properly seated.
