2.3 Installation of Memory Modules (DIMM)

A785GM motherboard provides two 240-pin DDR2 (Double Data Rate 2) 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 DDR2 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 DDR2 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.

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.
