Memory Population Rules and Configurations
The system supports two DDR2-400 DIMM slots for Channel A and two DDR2-400
DIMM slots for Channel B. The four slots are interleaved and placed in a row in the
following order: A1, B1, A2, B2 with A1 being closest to the MCH. This design supports
only registered ECC-enabled DIMMs.
When populating both channels, always place identical DIMMs in sockets that have the
same position on Channel A and Channel B (i.e., DIMM A2 should be identical to DIMM
B2). Refer to datasheet for definition of identical DIMMs.
In addition, single-rank DIMMs should be populated furthest from the MCH when a
combination of single-rank and double-rank DIMMs are used. This recommendation is
based on the signal integrity requirements of the DDR2 interface.
