IBM System x3530 M4 13
The following memory protection technologies are supported:
ECC

Chipkill (x4-based memory DIMMs)

Memory mirroring

Memory rank sparing

Chipkill works only in independent channel mode (default operational mode) and supports only x4-based
memory DIMMs.
If memory mirroring is used, then DIMMs must be installed in pairs (a minimum of one pair per each
processor, a maximum of two pairs per processor), and both DIMMs in a pair must be identical in type and
size.
If memory rank sparing is used, then two single-rank or dual-rank DIMMs must be installed per populated
channel (the DIMMs do not need to be 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.
Chipkill, memory mirroring, and memory rank sparing modes are mutually exclusive. Only one operational
memory mode can be enabled on a server, and it is a system-wide setting.
The following table lists memory options available for the x3530 M4 server.
