Notes:
1. Single channel mode is only tested and supported with a 512MB x8 FBDIMM installed in DIMM Slot A1.
2. The supported memory configurations must meet population rules defined above.
3. For best performance, the number of DIMMs installed should be balanced across both memory branches.
For Example: a four DIMM configuration will perform better than a two DIMM configuration and should be
installed in DIMM Slots A1, B1, C1, and D1.
An eight DIMM configuration will perform better then a six
DIMM configuration.
4. Although mixed DIMM capacities between channels are supported, Intel does not validate DIMMs in mixed
DIMM configurations.
3.1.3.3.1 Minimum Non-Mirrored Mode Configuration
The server board is capable of supporting a minimum of one DIMM installed.
However, for
system performance reasons, Intel’s recommendation is that at least 2 DIMMs be installed.
The following diagram shows the recommended minimum DIMM memory configuration.
Populated DIMM slots are shown in Grey.

Note: The server board supports single DIMM mode operation. Intel will only validate and
support this configuration with a single 512MB x8 FBDIMM installed in DIMM slot A1.
