– Supported memory modules:
10.1.1 Memory sequence
10.1.1.1 Population rules
– Populate memory slot 1 / channel A (DIMM 1A) first.
– In case of dual processor configurations, populate memory slot
1 / channel E (DIMM 1E) second.
– Within all channels, memory slot 1 must be populated prior to slot 2.
Slot 2 must be populated prior to slot 3 (for all CPUs).
– If memory modules with different ranks are used, always populate the higher
number rank DIMM first (starting from slot 1).
– If memory modules with different capacities are used:
