PowerBase can take only EDO DIMMs. It does not support interleaved memory. The three DIMM sockets are NOT identical. The first socket, which comes stock with a 16 MB DIMM installed, can only accept up to 32 MB DIMMs. The other two sockets can accept up to 64 MB DIMMs. The maximum memory is therefore 160 MB.
PowerBase has a socketed CPU daughter card which can be upgraded. No specifics on upgrades or upgradeability for PowerBase are available at this time.
Each PowerBase system comes with 16MB RAM, a 1.2GB IDE hard drive, 8x CD-ROM, 2MB IDO DRAM for graphics, and a 256K Level-2 Cache.
