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 4 . 4 . 2

1. While enabling "Branch 0 Rank Sparing":
- 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
the below table:
