Notes:
 Single channel mode is only tested and supported with a 512MB x8 FBDIMM installed in DIMM Slot A1.
 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 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 two DIMMs be installed.
The following diagram shows the recommended minimum DIMM memory configuration.
Populated DIMM slots are shown in gray.
