Appendix B

Installing Additional Memory

You can install additional memory—dynamic random-access memory (DRAM)—in your computer. DRAM allows you to work with more programs and larger documents. Additional memory comes in packages called Dual Inline Memory Modules, or DIMMs. Altogether, you can install a maximum (total) of 136 megabytes (MB) of DRAM in this Macintosh model. You can also install an optional High Performance Module (level 2 memory cache) in the cache slot in your computer for additional processing power.

WARNING Although instructions for installing DIMMs and a High Performance Module are provided in this manual, Apple Computer strongly recommends that you have an Apple-certified technician install additional DRAM or High Performance Modules. 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 install additional DIMMs yourself, you risk damaging your equipment, and this damage is not 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.

For more information about memory, see the “Memory” topic of Macintosh Guide, available in the Guide (h) menu.
