The following restrictions apply:
• Single channel mode is only tested and supported with a 512 Mbyte x8 FB-DIMM
installed in DIMM Slot A1.
• The supported memory configurations must meet the 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 performs better
than a two-DIMM configuration and should be installed in DIMM slots A1, B1, C1,
and D1. An eight-DIMM configuration performs better than a six-DIMM
configuration.
3.4.2.4 Non-mirrored Mode Minimum Configuration
The server board is capable of supporting a minimum of one installed DIMM. However,
for system performance reasons, Kontron recommends that at least two DIMMs be
installed.
Figure 21 shows the recommended minimum DIMM memory configuration. Populated
DIMM slots are shown in grey.

Mirroring: Y = Yes. Indicates that configuration
supports memory mirroring.
Sparing: Y(x) = Yes. Indicates that configuration
supports memory sparing, where x is one of the
following:
• 0: Sparing supported on Branch 0 only
