Upgrading the System Memory (RAM)

The computer has two memory sockets for 204 pin Small Outline Dual In-line (SO-DIMM) DDRIII (DDR3) type mem-

ory modules (see Memory page 1 - 2 for details of supported module types).

The total memory size is automatically detected by the POST routine once you turn on your computer.

2. The RAM is located at point

(Figure 10a).

3. Gently pull the two release latches on the sides of the memory socket in the direction indicated by the arrows (

& ) in Figure 10b.

4. The RAM module will pop-up

(Figure 10c), and you can remove it (see over).
