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:
