About memory
You can have memory—dynamic random-access memory (DRAM)—added
to your computer in packages called Dual Inline Memory Modules, or
DIMMs. You can also add an optional 256K Level 2 cache by installing a
High Performance Module.
DRAM configurations
Your computer can use any DRAM configuration with DIMMs of these sizes:
8, 16, 32, or 64 MB. DIMMs that are either 32 or 64 MB must support a 2K
refresh count.
You can increase your computer’s DRAM to up to a maximum of 136 MB (the
8 MB that comes on your computer’s main logic board, plus an additional 128
MB for a total 136 MB). The main logic board has two slots where DIMMs
can be installed. To increase DRAM to 136 MB, have an Apple-authorized
dealer or service provider fill both slots with 64 MB DIMMs. You can also fill
the slots with 8, 16, or 32 MB DIMMs. DIMMs of mixed sizes may be
installed—for example, you can install one 8 MB DIMM and one 16 MB
DIMM.
WARNING
To avoid damaging your computer and expansion card, do not
attempt to install any expansion card without first checking the
documentation for that card. If the documentation specifies that an
Apple-certified technician must install the card (usually because
the installation requires special training or tools), consult the service
and support information that came with your computer for instructions
on how to contact an Apple-authorized service provider or Apple for
assistance. If you attempt to install the card yourself, any damage you
may cause to your computer or card will not be covered by the limited
warranty on your computer. If the card is not an Apple-labeled product,
check with an Apple-authorized dealer or service provider to see if you
can install it yourself.
