Expanding memory
The random-access memory (RAM) in your computer can be expanded.
Installing additional RAM adds more memory chips to your computer and
expands its capabilities. The Tech n i c a l In fo r m a t i o n booklet that came with
your computer describes how much additional memory can be installed in
your Power Macintosh.
Memory for your computer is provided in packages called DRAM Single
Inline Memory Modules (SIMMs). The SIMMs must be the correct type for
your computer, and should be installed in pairs of the same size into paired
slots in your computer.
In a Power Macintosh that is not AV-equipped, the memory used to display
images on the screen (called video RAM, or VRAM) can also be expanded.
In an AV-equipped Power Macintosh computer, VRAM cannot be expanded.
It is very important that the DRAM SIMMs be correctly installed in your
Power Macintosh, because incorrect installation can result in errors,
unpredictable results, and damage to your equipment and data.
WARNING
To avoid damage to your computer, Apple recommends that
only an Apple-certified technician install additional RAM. 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 service. If you attempt to install additional RAM yourself, any
damage you may cause to your equipment will not be covered by the
limited warranty on your computer. See an Apple-authorized dealer or
service provider for additional information about this or any other
warranty question.
