* Maximum quantity supported is shown for two processors installed.

The following memory protection technologies are supported:

ECC

Chipkill (for x4-based memory DIMMs)

Memory mirroring

Memory rank sparing

If memory mirroring is used, DIMMs must be installed in pairs (minimum of one pair per each CPU), and

both DIMMs in a pair must be identical in type and size.

If memory rank sparing is used, then a minimum of one quad-rank DIMM or 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 installed.
