Installing Memory

Your Mac mini has two memory slots in which you can install a pair of 1 GB, 2 GB, or
4 GB memory modules, for a maximum of 8 GB of memory. For best performance, don’t
mix modules of different sizes; always install two identical memory modules.

Memory modules for your Mac mini must meet the following specifications:


Small Outline Dual Inline Memory Module (SO-DIMM) format


1333 MHz, PC3-10600E, DDR3 compliant (also called DDR3 1333)


Unbuffered and unregistered

You can purchase Apple memory from an Apple Authorized Reseller, the online Apple
Store at, or your local Apple Retail Store.


Always shut down your Mac mini and remove the power cord before

installing memory. Do not install memory while your Mac mini is plugged in.

Step 1:

Turn off your Mac mini.

Choose Apple () > Shut Down.

Step 2:

Disconnect all cables.

Step 7:

Reconnect the cables.

Reconnect the power cord and any other cables you disconnected.

Step 8:

Check the new memory.

Press the power button to turn on your Mac mini.

When you see the Mac OS X desktop, choose Apple () > About This Mac and check
that the reported amount of memory is correct.

If the reported memory size isn’t correct, or if your Mac mini repeatedly sounds three
tones, it’s having trouble recognizing a memory module. If this happens, shut down
your Mac mini, verify the module specifications against the requirements listed on
page 41, and then repeat the memory installation instructions to make sure the modules
are installed correctly. If you still have problems, remove the memory and consult the
support information that came with the memory, or contact the vendor who provided
the memory.
