The computer has two RAM expansion slots that accommodate standard SO (small outline) DIMMs using SDRAM devices. One or both slots may be occupied by factory-installed SO-DIMMs. The slots are accessible for user installation of an additional or larger SO-DIMM.
RAM expansion SO-DIMMs for both models must be PC133 compliant.
The SO-DIMMs must use SDRAM devices. If the user installs an SO-DIMM that uses EDO 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 accomodate up to 1 GB total RAM.
