Additional Information

Checking that your computer recognizes the new memory

To check that the computer recognizes the new memory:

  1. Start up your computer.
  2. When you see the Mac OS X desktop, choose Apple () from the upper-left menu bar, then choose About This Mac.

The total memory includes the amount of memory that originally came with the computer plus the new memory you added, or if all the memory has been replaced, the new total for that memory. For detailed information about the amount of memory installed in your computer, open System Profiler by choosing Apple (), then About This Mac; click More Info and then Memory from the Hardware section that appears in System Profiler.

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