Adding Memory

Your PC comes with random access memory (RAM),
which temporarily stores data and instructions on your
PC. The PC ships with one or more memory modules,
but you can replace the existing memory module(s)
with higher-capacity ones.
The motherboard contains sockets for DDR DIMMs
(double data rate dual in-line memory modules). The
exact number of sockets and type of DDR memory
module depends on which model PC you have.
DDR DIMM module example
To determine which type of memory module your
PC uses, and for specific memory module information
and specifications, go to the Web site listed in
your Warranty and Support Guide and click the
Support link.
WARNING: Using the wrong type of
memory module can damage the system.
