Expansion Features

This chapter describes the expansion features of the PowerBook G4 17-inch computer’s RAM expansion slots and the CardBus slot.

RAM Expansion Slots

The computer has two RAM expansion slots that accommodate standard SO (small outline) DIMMs using DDR SDRAM devices. One slot may is occupied by factory-installed SO-DIMM. The slots are accessible for user installation of an additional SO-DIMM.

The SO-DIMMs must use DDR SDRAM devices. If the user installs an SO-DIMM that uses Single Data Rate (SDR) devices, the boot process will fail when the user attempts to restart the computer and the computer will not operate.

The address logic for the RAM slots supports up to 1 GB total RAM. Using the highest-density devices currently available, an SO-DIMM can contain up to 512 MB of RAM, so the two RAM expansion slots can accommodate up to 1 GB total RAM.

Accessing the RAM Slots

The user can access the RAM expansion slots by removing the memory slot cover on the back of the computer, as shown in Figure 4-1(page 53). For complete instructions on accessing and replacing the RAM memory, refer to the PowerBook G4 17-inch Getting Started guide that came with the computer.
