Feature
Description
Recovery from single DRAM device failure (SDDC)
Recovery from Single DRAM Device Failure (SDDC) provides
error checking and correction that protects against any single
memory chip failure as well as multi- bit errors from any portion
of a single memory chip.
Failed DIMM isolation
This feature provides the ability to identify a specific failing
DIMM channel pair, thereby enabling the user to replace only the
failed DIMM pair.
Memory mirroring
Memory mirroring is a method of keeping a duplicate (secondary
or mirrored) copy of the contents of memory as a redundant
backup for use if the primary intra-socket memory fails. The
mirrored copy of the memory is stored in memory of the same
processor socket.
Memory address parity protection
This feature provides the ability to detect transient errors on the
address lines of the DDR channel.
Memory sparing (rank)
Memory sparing allocates one rank per channel as a spare. If
excessive correctable errors occur in a rank or channel, they are
moved to the spare area while the operating system is running to
prevent the errors from causing an uncorrectable failure.
Memory thermal throttling
This feature helps to optimize power/performance and can also
be used to prevent DIMMs from overheating.
