DIMMs
The memory subsystem will only support DDR SDRAM (Double Data Rate Synchronous Dynamic Random Access Memory)
technology utilizing industry-standard PC2100 type DDR SDRAM DIMMs, 1.2" tall. This is expected to be the standard
height available at first release and is currently being used by high-volume products. The DIMMs use a 184-pin JEDEC
standard connector.
DIMMs must be loaded in pairs. To enable chip sparing, four DIMMs of the same density must be loaded with specific
configuration rules. The following table summarizes memory solutions:
