Figure E-4 SIMMs and NVSIMM
The system board has 16 SIMM sockets physically divided into two rows of
eight. The SIMMs are also logically divided into four groups of four, known as
group 0, 1, 2, and 3. Figure E-5 shows SIMM locations and identifies groups.
A system board can be installed with zero memory or from one to four groups
filled. For example, 0 SIMMs, 4 SIMMs, 8 SIMMs, 12 SIMMs or 16 SIMMs.
When installing memory, first install all group 0 SIMMs on all system boards,
from the lowest board slot number to the highest. Then, install group 1 SIMMs
in the same order, followed by groups 2 and 3 for the remaining SIMMs.
