Description

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.

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, they are moved to the spare area while the

operating system is running to prevent the errors from causing an uncorrectable

failure.

This feature helps to optimize power/performance and can also be used to

prevent DIMMs from overheating.
