Figure 65. Population with Non-identical DDR3 DIMMs
x DIMMs within a Lock step pair must be of same organization. In the above configuration, DIMM 1/B & DIMM 1/D
should be of the same organization.
x However, DIMMs across lock step DIMM pairs need not be identical. For example, DIMM 1/B and DIMM 2/B can
be of different type.
x In the above configuration, DIMM sparing is not supported.
Figure 66. Minimal Population for Intra Socket Mirroring
x {DIMM 1/B, DIMM 1/D} pairs of both boards must be identical in organization, size, and speed.
x Figure 66 shows the minimum population for Intra Socket Mirroring
