2.3 Installation of Memory Modules (SO-DIMM)

AD2550B-ITXmotherboard provides two 204-pin DDR3 (Double Data Rate 3) SO- DIMM slots.

1.It is not allowed to install a DDR or DDR2 memory module into DDR3 slot; otherwise, this motherboard and SO-DIMM may be damaged.

2.Please install the memory module from DDR3_A2 slot for the first priority.

Installing a SO-DIMM

Please make sure to disconnect power supply before adding or removing SO-DIMMs or the system components.

Step 1. Unlock a SO-DIMM slot by pressing the retaining clips outward. Step 2. Align a SO-DIMM on the slot such that the notch on the SO-DIMM

matches the break on the slot.

The SO-DIMM only fits in one correct orientation. It will cause perma- nent damage to the motherboard and the SO-DIMM if you force the SO- DIMM into the slot at incorrect orientation.

Step 3. Firmly insert the SO-DIMM into the slot until the retaining clips at both ends fully snap back in place and the SO-DIMM is properly seated.
