IBM System x3750 M4 12
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.
The following table lists the memory options that are available for the x3750 M4 server.
