* Support is planned for later in 2013.
** Maximum quantity supported is shown for two processors installed. When one processor is installed, the
maximum quantity supported is a half of the quantity that is shown.
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.
