Asrock imb-147 series 用户手册

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

Step 1.  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 per-
manent damage to the motherboard and the DIMM if you force 
the DIMM into the slot at incorrect orientation.

Step 2.  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.
