mIf you want to install additional DRAM yourself, you must purchase the memory chips, or DIMMs, from an Apple-authorized dealer. Then follow the instructions in this appendix.

mIf you want an Apple-certified technician to install additional DRAM for you, see 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.

DRAM configurations

Your computer can use any DRAM configuration with DIMMs of these sizes: 8 MB, 16 MB, 32 MB, or 64 MB. The exact configuration depends on the density of the DRAM chips that are mounted on the DIMMs. Use only DIMMs that support a 1K or 2K refresh count. Do not use DIMMs that support a 4K refresh count.
