104 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.
