5-3. How to install DDR/SDRAM DIMM 

Module 

1. The DDR DIMM socket has a 

“ Plastic Safety Tab”, and the 

DDR DIMM memory module has 

an Asymmetrical notch”, so the 

DDR DIMM memory module can 

only fit into the slot in one 

direction  

2. Push the tabs out. Insert the 

DDR DIMM memory modules into 

the socket at a 90-degree angle, 

then push down vertically so that 

it will fit into the place.

3. The Mounting Holes and plastic tabs should fit over the edge and 

hold the DDR DIMM memory modules in place.
