In any mode, the maximum operational speed is determined by the slowest memory module in the
system.
Installing memory modules
There are two memory sockets on the system board. To remove or install memory modules:
1. Remove all removable media, such as USB flash drives, from the computer.
2. Turn off the computer properly through the operating system, and turn off any external devices.
3. Disconnect the power cord from the AC outlet and disconnect any external devices.
IMPORTANT: You must disconnect the power cord and wait approximately 30 seconds for the power to
drain before adding or removing memory modules. Regardless of the power-on state, voltage is always
supplied to the memory modules as long as the computer is plugged into an active AC outlet. Adding or
removing memory modules while voltage is present may cause irreparable damage to the memory
modules or system board.
4. Remove the base unit rear and front access panels. See Removing and replacing the base unit access
covers on page 12 .
5. To locate the memory modules on the system board, see Locating internal components on page 16 .
6. To remove a memory module, press outward on the two latches on each side of the memory module (1),
and then pull the memory module out of the socket (2).
7. To install a memory module, slide the memory module into the socket at approximately a 30° angle (1),
and then press the memory module down (2) so that the latches lock it in place.
NOTE: A memory module can be installed in only one way. Match the notch on the module with the tab
on the memory slot.
