Feature Failed DIMM isolation Memory mirroring: intra-socket Memory address parity protection Memory sparing (rank) Memory thermal throttling Description 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 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 memory fails. The mirrored copy of the memory is stored in memory of the same processor socket. This feature provides the ability to detect transient errors on the address lines of the DDR channel. Memory sparing allocates one rank per channel as a spare. If excessive correctable errors occur in a rank or channel, it is moved to the spare area while the operating system is running to prevent the error from causing an uncorrectable failure. This feature helps to optimize power/performance and can also be used to prevent DIMMs from overheating. For information on memory mirroring and sparing configurations, see the Dell PowerEdge T320 Systems Owner's Manual on Support.Dell.com/Manuals.

Feature
Description
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:
intra-socket
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
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, it is moved to the spare area while the operating
system is running to prevent the error 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.
