Memory Map And Population Rules - Intel 5000 Series Datasheet

System BIOS
Demand scrubbing is not possible when memory mirroring is enabled. Therefore, the BIOS will
disable it automatically if the memory is configured for mirroring.
Note: Memory sparing and mirroring features are currently disabled and will be made available
after production launch.

Memory Map and Population Rules

The nomenclature to be followed for DIMM sockets is as follows.
Note: Memory map and population rules may vary by product. See the server or workstation
Technical Product Specification that applies to your product for more detailed information.
3.3.7.1 Memory Sub-system Nomenclature
FBDIMMs are organized into physical slots on memory channels that belong to memory
branches.
Each branch can support a maximum of four DIMM sockets per channel.
The memory channels are identified as Channel A, B, C, and D.
Channels A and B belong to Branch 0. Channels C and D belong to Branch 1.
The DIMM identifiers on the silkscreen on the board provide information about which
channel, and therefore which branch, they belong to. For example, DIMM_A1 is the first
slot on Channel A on Branch 0. DIMM_C1 is the first DIMM socket on Channel C on
Branch 1.
