Removing the Primary System Memory (RAM)
The computer has three memory sockets for 204 pin Small Outline Dual In-line (SO-DIMM) DDR3L type memory modules.
The total memory size is automatically detected by the POST routine once you turn on your computer.
Note that three SO-DIMMs are only supported by Quad-Core CPUs; Dual-Core CPUs support two SO-DIMMs maxi-
mum.
Two primary memory sockets are located under component bay cover (the bottom case cover), and one secondary
memory sockets are located under the keyboard (not user upgradable). If you are installing only two RAM modules
then they should be installed in the primary memory sockets under the component bay cover.
