Removing and Installing Parts
Memory
You can increase your computer memory by installing memory modules on
the system board.
Memory Overview
• Memory modules should be installed in pairs of matched memory size,
speed, and technology. If the memory modules are not installed in matched
pairs, the computer will continue to operate, but with a slight reduction in
performance. See the label in the upper-right corner of the module to
determine the module’s capacity.
