DDR DIMMs must be 184-pin unbuffered DDR SDRAM (double data rate synchronous dynamic random access memory). The PC ships with one or more memory modules, but you can replace the existing memory module(s) with higher-capacity ones. You can install 64 MB, 128 MB, 256 MB, or 512 MB memory modules in the computer.
