Installing Additional Memory

Your computer comes with two memory slots, one above the other, that you access by removing your PowerBook keyboard. Your computer comes with a 128 megabyte (MB) Synchronous Dynamic Random-Access Memory (SDRAM) module installed in the lower slot. The upper memory slot can accept a SDRAM module that meets the following specifications:

mSmall Outline-Dual Inline Memory Module (SO-DIMM) format

m1.25 inch or smaller

m64, 128, 256, or 512 MB

m144-pin

mPC-133 Type RAM

SDRAM from an earlier PowerBook that meets these specifications can be used with your PowerBook.

The maximum amount of RAM you can install in your PowerBook is 1 GB, using 512 MB DIMMs in both the upper and lower RAM slots.
