If two DDR3 SDRAM modules are already installed in the memory slot, 
remove one of them to make room for the new one by pulling out on the 
latches on both edges of the socket at the same time. Be sure to save the 
old DDR3 SDRAM for future use.

5

Align the notch of the DDR3 SDRAM module with the protrusion of the 
socket and gently insert the new module at a 30-45° angle.

6

Push the DDR3 SDRAM module down until the latches on both sides of 
the socket lock into its position.

7

After aligning the attachment clips with their matching gaps, reinstall the 
bottom slot cover.
