Memory
You can increase your computer memory by installing memory modules on the system board. For information on the type
of memory supported by your computer, see Memory.
Memory Overview
● Memory modules should be installed in pairs of matched memory size, speed, and technology for best performance.
Otherwise, the computer will continue to operate, but with a slight reduction in performance. See the label on the
module to determine the module's capacity.
