Mode” as Mirror), Branch 1 contains a replicate copy of the data in Branch 0. The

DIMMs must cover the same slot position on both branches. DIMMs that cover a

slot position must be identical with respect to size, speed, and organization. DIMMs

within a slot position must match each other, but aren’t required to match adjacent

slot positions.
