At configuration time, a DIMM rank is set aside to replace a defective DIMM

rank. When the error rate for a failing DIMM rank reaches a pre-determined

threshold, the memory sparing function will issue an interrupt and initiate a

spare copy. At the completion of the copy, the failing DIMM rank is disabled

and the “spared” DIMM rank will be used in its place. Refer to

- The system will auto select the largest pair ranks size in the channel 0 or

1 of the Branch 0 and assign as the sparing DIMMs. The total

memories size will also reduce the largest ranks size in the channel 0

or 1 of the Branch 0.

- Rank Sparing in the Branch 0 only supports 4/6/8 memory populations as
