RAM Expansion

The main logic board has four RAM expansion slots for SDRAM DIMMs. At least one of the RAM expansion slots contains a factory installed SDRAM DIMM.

The SDRAM DIMMs can be installed one or more at a time. The system supports linear memory organization; no performance gains are seen when two DIMMs of the same size are installed. Any supported size DIMM can be installed in any DIMM slot, and the combined memory of all of the DIMMs installed is configured as a contiguous array of memory.
