* Maximum quantity supported is shown for four processors installed. When two processors are installed,
the maximum quantity supported is a half of the quantity that is shown. When one processor is installed,
the quantity is one quarter of that shown.
The following memory protection technologies are supported:
ECC
Chipkill (for x4-based memory DIMMs; look for "x4" in the DIMM description)
Memory mirroring
Memory rank sparing
If memory mirroring is used, then DIMMs must be installed in pairs (minimum of one pair per 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.
