The supported memory configurations must meet population rules defined above.
-
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.

Although mixed DIMM capacities between channels is supported, Intel does not validate DIMMs
in mixed DIMM configurations.

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.

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.
