* Maximum quantity supported is shown for all processors that are installed
The following memory protection technologies are supported:
ECC
Chipkill (for x4-based memory DIMMs)
Redundant bit steering (Double Device Data Correction)
Memory mirroring
Memory rank sparing
Chipkill and Redundant Bit Steering are supported in RAS mode. Chipkill is supported in Performance
mode.
If memory mirroring is used, DIMMs must be installed in pairs for Performance mode (minimum of one pair
per each processor) and quads for RAS mode. DIMMs in the pair/quad must be identical in type and size.
If memory rank sparing is used, then a minimum of two single-rank or dual-rank DIMMs must be installed
per populated channel (the DIMMs do not need being identical). In rank sparing mode, one rank of a DIMM
in each populated channel is reserved as spare memory. The size of a rank varies depending on the
DIMMs that are installed.
