Intel MFS2600KIB manual 23

Functional Architecture Intel® Compute Module MFS2600KI TPS

Rank Sparing Mode is only possible when all channels that are populated with memory meet the requirement of having at least two SR or DR DIMM installed, or at least one QR DIMM installed, on each populated channel.

Lockstep or Mirroring Modes require that for any channel pair that is populated with memory, the memory population on both channels of the pair must be identically sized.

DIMM population rules require that DIMMs within a channel be populated starting with the BLUE DIMM slot or DIMM farthest from the processor in a “fill-farthest” approach. In addition, when populating a Quad-rank DIMM with a Single- or Dual-rank DIMM in the same channel, the Quad-rank DIMM must be populated farthest from the processor.
