Memory Notes

1. Four DIMMs of the same size form a group.
2. The minimum memory configuration is sixteen DIMMS.
3. Memory errors include CPU number, J number, and Slot location.
4. DIMM groups associated with a failed CPU are unavailable for use.
5. Interleaving is limited to memory on the same CPU/Memory Board.
6. Two-way interleaving occurs in any group when the DIMM size does not match the size used in any other group.
7. Four-way interleaving occurs between any two groups when the DIMM sizes are the same.
8. Eight-way interleaving occurs when the DIMMs in all four groups are the same size.
